Description

This technology relates to a design support device, a design support method, and a design support program.

A floor plan design support device has been proposed that selects a desired floor plan from among many floor plans stored in a database based on zoning information for rooms arranged in a building (for example, Patent Document 1). This device is said to have a database that stores multiple floor plans including information on the exterior shape and dimensions of the building, and information on the type, location, and size of rooms arranged in the building, an input means for inputting similar information as zoning information, an extraction processing means for extracting floor plans similar to the exterior shape and dimensions of the building, a selection processing means for selecting floor plan PL with a similar room arrangement, and a display means.

Japanese Patent Application Publication No. 8-77218

When selecting a desired floor plan from a large number of floor plans, floor plans that match the zoning information must be stored in a database beforehand. However, preparing a variety of floor plans is time-consuming, and there is also the problem that it cannot be handled unless floor plans that match the zoning information are stored.

The present invention aims to provide a technology that can generally assist in floor plan planning.

The design support device according to the present invention includes an area placement unit that places areas of predetermined sizes within the planar shape of a building or dwelling unit in association with the type of each room according to the planar shape and the configuration of the rooms to be placed within the planar shape, and an area expansion unit that expands the placed areas within the planar shape based on predetermined rules.

By expanding the area under defined rules, it becomes possible to propose floor plans that fully utilize the area given to a building or dwelling unit. In other words, it becomes possible to provide technology that can generally assist in floor plan planning.

The system may further include a relationship confirmation unit that determines whether the areas arranged within the planar shape meet a specified adjacent relationship required between the areas. The adjacent relationship may also include information that defines a lower limit for the passageway width between the areas. In this way, it becomes possible to propose a design that meets the minimum relationship between areas that can generally be traveled between. Note that a fixed value may be set instead of a lower limit for the passageway width.

The system may further include an evaluation unit that calculates an evaluation value for the expanded area based on a predetermined evaluation criterion associated with the type of area. In this way, the generated design can be objectively evaluated based on a certain criterion. In other words, when multiple plans are mechanically generated, an index can be obtained for selecting a plan to be proposed to the user.

The type may include at least living rooms, including living rooms or bedrooms, and corridors, and the evaluation criteria may be such that the lower the corridor rate, which is the proportion of the corridor in the planar shape, the higher the evaluation. The type may include at least dwelling units and common areas, including corridors, stairs, or elevators, and the evaluation criteria may be such that the lower the common area rate, which is the proportion of the common areas in the planar shape, the higher the evaluation. In this way, it can be applied to planning such as the layout of a house or floor plans in an apartment building.

The contents of the means for solving the problem may be combined as much as possible without departing from the problem and technical idea of the present invention. The contents of the means for solving the problem may be provided as a device such as a computer or a system including multiple devices, a method executed by a computer, or a program executed by a computer. The program may also be executed over a network. A recording medium holding the program may also be provided.

The present invention provides a technology that can generally assist in floor plan planning.

The following describes an embodiment of the present invention with reference to the drawings.

<Device Configuration>
FIG. 1 is a block diagram showing an example of a design support device according to the present invention. The design support device 1 is a general computer and supports planning of a floor plan of a house. For example, the design support device acquires a planar shape of a building or a dwelling unit and a reference position associated with a type of area to be placed inside the planar shape. The reference position may be determined randomly, for example, or may be determined randomly after zoning in advance for areas such as a living room and a bedroom. In addition, an area of a size predetermined in association with the type is placed in the planar shape based on the reference position. Then, based on a rule predetermined in association with the type, the placed area is expanded within a range that fits within the planar shape. For example, the rule is set to make the living room larger and the bathroom and hallway smaller. Under a general rule, a desired design can be automatically performed by expanding the area so as to maximize the sales area, so to speak.

The design support device 1 according to the present invention is a general computer and has a communication I/F (Interface
The computer system includes a memory device 11 , an input/output I/F (Interface) 13 , a processor 14 , and a bus 15 .

The communication I/F 11 is, for example, a wired network card or a wireless communication module, and transmits and receives information to and from other computers via a network (not shown). The storage device 12 is a main storage device such as a RAM (Random Access Memory) or a ROM (Read Only Memory), and an auxiliary storage device (secondary storage device) such as a HDD (Hard-disk Drive), an SSD (Solid State Drive), or a flash memory. The main storage device caches programs and data read by the processor and secures a working area for the processor. The auxiliary storage device stores programs and BIM (Building Information Modeling) data executed by the processor.
The input/output I/F 13 is connected to input devices such as a keyboard, a mouse, and a touch panel, and an output device such as a printer. Through the input/output I/F 13, operations by a user are accepted and information is output to a user.

The processor 14 is an arithmetic processing device such as a CPU (Central Processing Unit) and executes a program to perform each process according to the present embodiment. Specifically, the processor 14 functions as a condition acquisition unit 141, a region placement unit 142, a relationship confirmation unit 143, a region expansion unit 144, a consistency confirmation unit 145, and an evaluation unit 146.

The condition acquisition unit 141 acquires the planar shape of the building or dwelling unit and a reference position to be placed on the planar shape. The reference position is associated with a type of area, such as a room, hallway, or storage. The planar shape and reference position are, for example, input from a user via the input/output I/F 13 or are randomly determined and stored in the storage device 12. The reference position may be determined randomly within a range defined in a rough layout pattern of areas based on zoning.

The area placement unit 142 places areas, the sizes of which are determined in advance in association with the type, in a planar shape according to a reference position. In this embodiment, each area is rectangular, and depending on the type of area, such as a room, hallway, or storage, for example, a minimum value is determined for at least one of the short and long sides, and this information is stored in the storage device 12. The area placement unit 142 places each area at an initial size, which is, for example, the minimum value.

The relationship confirmation unit 143 determines whether a predetermined adjacent relationship required between the types of areas is satisfied. The predetermined adjacent relationship is, for example, that between a room and a hallway, that the areas must be adjacent, and the minimum width of the passage between the areas is specified, and this information is stored in the storage device 12.

The area expansion unit 144 expands the placed area based on a predetermined rule to the extent that it fits within the planar shape. The predetermined rule, for example, specifies whether or not expansion is required in association with the type of area, and is stored in the storage device 12. Depending on the type of area, the area may be expanded in a predetermined stepwise manner, or the area may be expanded steplessly. Also, different priorities may be specified depending on the type of area, and the area may be expanded according to the priority. Depending on the type of area, such as a toilet, bathroom, or kitchen, the area may not be expanded.

The consistency checking unit 145 determines whether the above-mentioned relationships are maintained for each area after expansion, for example.

The evaluation unit 146 calculates an evaluation value for the expanded area based on a predetermined evaluation criterion. For example, the evaluation criterion may be such that the lower the corridor ratio, which is the ratio of the corridor to the planar shape, the higher the evaluation. In addition, when making a floor plan for the planar shape of a dwelling unit, the types include at least the dwelling unit and common areas including corridors, stairs, or elevators, and the evaluation criterion may be such that the lower the common area ratio, which is the ratio of the common areas to the planar shape, the higher the evaluation.

The above components are connected via a bus 15. Note that the design support device 1 may not include some components such as the communication I/F 11 and the input/output I/F 13. The design support device 1 may be provided on a so-called cloud and output the results of the processing according to this embodiment to another computer via a network not shown, such as the Internet. These functions may be distributed and executed on multiple computers, or may be executed in parallel by multiple computers.

<Constraints (rules), relationships, and scoring>
FIG. 2 is a diagram for explaining an example of constraints (rules), requirements regarding the relationship of adjacency, and score calculation regarding evaluation, which are set in advance for the type of area. In the table of FIG. 2, the attributes of "constraints (rules)", "relationships", "expansion priority", and "addition/subtraction points" are defined in association with "type". It is assumed that such information is stored in the storage device 12 in advance. In the type field, "living room", "bathroom", "entrance", "corridor", and "storage" are registered. "Living room" is further divided into various types such as "living room (LD, living/dining room)", "master bedroom (MBR)", and "bedroom (BR)". "Bathroom" is further divided into various types such as "kitchen (K, kitchen)", "bathroom (UB)", and "toilet (WC)". "Storage" is further divided into various types such as "shoe closet" or "SIC (shoe in closet)", "closet" or "WIC (walk-in closet)", "storage room" or "storage room".

As "constraints (rules)" for each type, the minimum value of the short side, the minimum value of the depth, fixed dimensions of the width or depth, fixed dimensions in stages for the short side and the long side, etc., can be predefined. Note that specific numerical values are omitted in FIG. 2. As "relationships" for each type, the connection relationship between areas related to other types and the minimum value of the connection width, the area to be arranged concomitantly and the necessary connection relationship between the area and areas related to other types, the number or the minimum area of areas related to each type to be provided for one dwelling unit, etc. can be predefined. As "expansion priority" for each type, a number representing the priority order can be predefined. For example, each area arranged in the initial size is expanded according to the priority order. As "addition/deduction elements" for each type, the calculation method of the evaluation value, such as the addition or deduction according to the distance between areas related to different types, the area of the area related to each type, the ratio of the area of the area related to each type to the total area, and the ratio of the area of the area related to each type to the target value of the area of the area related to each type that is separately determined, can be predefined.

<Conditions>
The above-mentioned house layout may be applied to the layout of a detached house or to the layout of each dwelling unit of an apartment building. In this embodiment, the plan shape of the dwelling unit (in other words, the outline on the plan view) is assumed to be predetermined. FIG. 3 is a diagram showing an example of a target area set for each type of area for variations of floor plans such as 1LDK, 2LDK, and 3LDK. The table in FIG. 3 defines the target area (numerical values are omitted in the example of FIG. 3) for each type of area for each "floor plan" and "dwelling unit area". Such information is used, for example, in designing the floor plan of each dwelling unit of an apartment building, by reading out the target value according to the type of floor plan (in other words, the number of rooms) and the area of the entire dwelling unit, and is used, for example, in the enlargement process and evaluation process described later. Such information is assumed to be stored in the storage device 12 in advance.

<Processing>
Fig. 4 is a process flow diagram showing an example of a process executed by the design support device. The condition acquisition unit 141 of the design support device 1 performs a setting read process (Fig. 4: S1). In this step, settings related to the building to be designed and operation conditions shown in Fig. 2 and the like are read. Details of this step are shown in Fig. 5.

5 is a process flow diagram showing an example of the setting read process. The condition acquisition unit 141 reads out the room configuration of the dwelling unit to be processed in the planning and the planar shape of the building or dwelling unit from the storage device 12 (FIG. 5: S11). The room configuration of the dwelling unit is information representing the rooms to be provided in the dwelling unit, such as 2LDK or 3LDK. The shape of the dwelling unit includes information indicating whether the walls surrounding the dwelling unit are interior walls or exterior walls in addition to the planar shape of the dwelling unit. The condition acquisition unit 141 also acquires constraints on the size of each room (FIG. 5: S12). In this step, information on the size of each area, for example, registered in the constraint (rule) field in FIG. 2, is read out from the storage device 12. The condition acquisition unit 141 also reads out conditions on the relationship between areas from the storage device 12 (FIG. 5: S13). In this step, for example, conditions on the connection relationship between areas, registered in the relationship field in FIG. 2, are read out from the storage device 12. The condition acquisition unit 141 also acquires the rules for the extension process (FIG. 5: S14). In this step, for example, a number indicating the extension priority registered in the extension priority field in FIG. 2 is read from the storage device 12. Note that the processes in S11 to S14 may be executed in a different order or in parallel. Then, the process returns to FIG. 4.

Then, the design support device 1 performs design processing (FIG. 4: S2). In this step, the information read in S1 is used to arrange rooms within the dwelling unit and determine the size of the rooms. Details of this step are shown in FIG. 6.

Figure 6 is a process flow diagram showing an example of a design process. The area placement unit 142 of the design support device 1 places rooms within the dwelling unit based on predetermined conditions (Figure 6: S21). In this step, the area placement unit 142 places areas according to the room configuration acquired in S11, for example randomly, within the planar shape of the dwelling unit acquired in S11. Alternatively, information representing a zoning pattern for each room configuration may be determined in advance, and the area placement unit 142 may randomly place areas within the range determined by the pattern.

7 and 8 are diagrams for explaining an example of a zoning pattern. FIG. 7 shows a pattern when the room configuration is 1LDK and 2LDK. FIG. 8 shows a pattern when the room configuration is 3LDK. Note that the thick lines indicate the outer periphery of the planar shape of the dwelling unit. The thick solid lines indicate the inner wall between the adjacent dwelling units, the thick dashed lines indicate the outer wall on the balcony side, and the thick two-dot chain lines indicate the outer or inner wall with the common corridor. For 2LDK and 3LDK, different patterns are defined for a corner dwelling unit located at the corner of the planar shape of the building and surrounded by outer walls on two or more sides in addition to the common corridor, and a middle dwelling unit with other dwelling units on both sides and surrounded by outer walls on one side in addition to the common corridor. In addition, even if the room configuration is the same, multiple patterns may be defined. For each pattern, a rough range (rounded rectangle in FIG. 7 and FIG. 8) in which areas such as the living room (LD), kitchen (K), and bedroom (BR) should be arranged is defined. In S21, one of the patterns is selected depending on the room configuration of the dwelling unit to be processed, and, for example, each area is randomly arranged within a predetermined rough range, and areas with no predetermined range may be randomly arranged.

7 and 8 may be defined based on rules registered in the relationship field in Fig. 2. For example, the areas may be arranged randomly within a range that satisfies the following rules:
- Place the living/dining room in the corner, and the master bedroom (MBR) facing the other end of the exterior wall - Place the kitchen adjacent to the living/dining room - Place at least one of the bedrooms (MBR, BR2, BR3) adjacent to the living/dining room, with the other BRs prioritized in locations facing the exterior wall By zoning as described above and then randomly placing the rooms, it becomes possible to perform an automatic design within a reasonable range to a certain extent.

The placement may be determined based on a position specified by a user operation. For example, the condition acquisition unit 141 reads pre-stored information defining the planar shape of the building or dwelling, and presents it to the user via the input/output I/F 13. The user then clicks or taps on a position within the area to specify coordinates within the planar shape, and the condition acquisition unit 141 acquires the reference position via the input/output I/F 13.

Figure 9 is a diagram showing an example of the planar shape of a building or dwelling unit and the reference position at which it is located. In the example of Figure 9, the planar shape of the dwelling unit is represented by a rectangle. Also, points indicating the reference position are placed inside the planar shape. Also, for convenience, information indicating the type of area associated with each point is displayed near each point. In S21, such information may first be determined randomly, or randomly under certain constraints, or based on the user's instructions.

Figure 10 is a diagram showing an example of arranged areas. In the example of Figure 10, corresponding areas are arranged so as to include the reference position arranged in Figure 9. Each area has a minimum size, for example, as specified in Figure 2. Also, each area may be arranged along the outer wall of the dwelling unit. Note that the short straight lines represent the positions of the passageways provided between each area. In S21, an arrangement as shown in Figure 10 is generated. Also, in S21, multiple arrangement patterns may be generated.

Then, the relationship confirmation unit 143 of the design support device 1 judges whether the placed area satisfies a predetermined relationship (FIG. 6: S22). In this step, the relationship confirmation unit 143 judges whether the area satisfies the requirements defined in the "relationship" field shown in FIG. 2.

Figure 11 is a diagram showing an example of relationship requirements. The relationships in Figure 2 can be illustrated, for example, as shown in Figure 11. In Figure 11, areas related to each type are shown as rectangles. Also, the relationship between areas that require a connection or between areas that can be connected is shown with a bidirectional arrow. Here, a connection means that there is a connection between areas so that they can move back and forth. Also, a minimum connection width may be set for each connection part.

In S22 of FIG. 6, the relationship between the regions is determined as to whether the regions that require connection are connected correctly, and if they are connected, whether the required connection width is secured. Note that if it is determined in S22 that the requirements for the relationship are not met, the process may return to S21 and the regions may be rearranged (not shown). Alternatively, multiple arrangement patterns may be generated in S21, and the pattern that is determined in S22 to meet the required relationship may be used in subsequent processing. Alternatively, the processes of S21 and S22 may be executed together, and the regions may be arranged randomly within a range that meets the required relationship.

The area expansion unit 144 of the design support device 1 expands the arranged area according to the processing rules (FIG. 6: S23). In this step, the size of the area arranged in S21 is expanded steplessly for areas with a specified minimum size, or stepwise for areas with a specified step size. It is also possible to expand each area with a different priority based on the value shown in the expansion priority field shown in FIG. 2. With the expansion process in this step, the area of the corridor or entrance that is not the target of expansion is reduced within a range that satisfies a specified minimum width, etc. With the expansion of a certain area, the position of the adjacent area may be slid into the area that is not the target of expansion. In this way, the area of the dwelling is fully utilized to fit the required rooms into the dwelling.

Figure 12 is a diagram for explaining the expansion process. In Figure 12, an outward arrow is displayed on the area to be expanded. The area to be expanded is, for example, an area in which a numerical value is registered in the expansion priority field shown in Figure 2. Also, in the constraint (rule) field in Figure 2, the area is an area whose short or long side, or whose width or depth is not fixed. In other words, an edge with a specified minimum dimension or an edge with an unfixed dimension may be expanded. Also, the distance between the areas may be changed to increase the score based on the evaluation criteria shown in the addition/subtraction points element, or the area may be expanded to increase the area.

Figure 13 is a diagram showing an example of a floor plan after the area has been expanded. In Figure 13, the area indicated by the arrow in Figure 12 has been expanded as much as possible while still remaining within the range of the planar shape showing the exterior shape of the building or dwelling, and its position has been adjusted in accordance with the expansion.

Then, the consistency checking unit 145 of the design support device 1 checks whether the expanded area has consistency (FIG. 6: S24). In this step, the consistency checking unit 145 checks whether the floor plan after expansion in S23 satisfies the constraints and relationships shown in FIG. 2. If it is determined that there is no consistency, the process may return to S21 and perform the layout again, or the process may return to S23 and expand again by changing the priority of each area (not shown). In addition, a floor plan may be generated based on multiple layout patterns, and the floor plan determined in S24 to satisfy the required relationships may be used in the subsequent processing. In addition, the processes of S23 and S24 may be executed together, and the area may be expanded to the extent that the required relationships are satisfied.

The evaluation unit 146 of the design support device 1 also calculates an evaluation value for the floor plan designed according to a predetermined evaluation criterion (S25 in FIG. 6). For example, the evaluation unit 146 may increase or decrease the score based on the adding/deleting point elements shown in FIG. 2 relative to the reference score, and may also subtract points if the target size shown in FIG. 3 is not met. If the target size is not met, the target value or priority may be modified and the process may return to S21 or S23 to repeat the process (not shown). In this way, a value representing the evaluation of the generated floor plan is calculated. This ends the design process, and the process returns to FIG. 4.

The evaluation unit 146 also outputs the generated floor plan (FIG. 4: S3). For example, the evaluation unit 146 may present the generated floor plan and the evaluation value to the user via the input/output I/F 13, or may output them to a specified file. Also, the evaluation unit 146 may be configured to output multiple floor plans.

FIG. 14 is a diagram showing an example of an output floor plan. The table in FIG. 14 includes attributes of No., room area, area evaluation, storage evaluation, evaluation total (A), and overall evaluation (100-A). The room area includes attributes of the number of tatami mats in the living and dining room, the number of tatami mats and storage in the MBR, the number of tatami mats and storage in the BR2, and the number of tatami mats and storage in the BR3. The area evaluation includes attributes of the living and dining room, MBR, BR2, and BR3. The storage evaluation includes attributes of shared, SIC, MBR, BR2, and BR3. The room area and its evaluation of the generated floor plan are registered in each record with a serial number in the No. field. The area of each area is registered in a predetermined unit such as "tatami mats" in the room area field. In addition, in the area evaluation and storage evaluation fields, points are registered based on the addition and deduction point elements shown in FIG. 2, for example. In addition, in the evaluation total (A) field, the total value of the area evaluation and storage evaluation is registered. In addition, the overall evaluation (100-A) field registers an evaluation value obtained by subtracting the total evaluation (A) value from 100 points (full marks). Note that while the example in FIG. 14 shows an example in which points are subtracted when the criteria are not met, it is also possible to add points or to perform evaluation by adding or subtracting points. Such evaluations are output for each floor plan to be generated. Also, by selecting each record, it is also possible to display the floor plan corresponding to each record, as shown in FIG. 13, for example. This concludes the design support process.

＜Effects＞
According to the design support process of this embodiment, by expanding the area under a predetermined rule, it is possible to propose a floor plan that is generally preferable and makes full use of the area of the building. In other words, it is possible to provide a technology for supporting floor plan planning in a general purpose manner.

＜Other＞
The details of the process shown in Fig. 4 and the like are merely examples, and the details of the floor plan design process are not limited to the above examples. For example, the design process shown in Fig. 6 may learn multiple existing floor plans and generate a floor plan based on the relationship between the room configuration and the location of the dwelling unit and the characteristics of the layout of the rooms within the dwelling unit. In this case, too, a floor plan that makes full use of the area can be generated according to the planar shape of the dwelling unit by processing to expand the area under a predetermined rule.

The planar shape of the exterior of the building or dwelling unit may not be a simple rectangle, but may include columns or parts where the connections between the walls are not perpendicular. In such cases, the process in S4 of FIG. 4 may involve expansion of the exterior wall parts of the building or dwelling unit that do not fit within the planar shape.

In addition, information about the beams of the building may be included, and the area may be positioned so that the beams are not located at the center (center of gravity) of the room. Such constraints allow for a design that will not cause problems when installing lighting in the room.

The above-described embodiment is merely an example, and the present invention is not limited to the above-described configuration. The subject matter of the present invention also includes a computer program for executing the above-described processing, and a computer-readable recording medium on which the program is recorded. The recording medium on which the program is recorded enables the above-described processing by causing a computer to execute the program.

Note that a computer-readable recording medium is a recording medium that stores information such as data and programs through electrical, magnetic, optical, mechanical, or chemical action and can be read by a computer. Among such recording media, those that can be removed from a computer include flexible disks, magneto-optical disks, optical disks, magnetic tapes, memory cards, etc. Furthermore, recording media that are fixed to a computer include HDDs, SSDs (Solid State Drives), ROMs, etc.

expanding the arranged area based on a predetermined rule within a range that fits within a planar shape of the dwelling unit ;
calculating an evaluation value for the expanded area based on an evaluation criterion related to an area of the area, the evaluation criterion being predetermined in association with the type of the room;
expanding a section area associated with a type of section including the dwelling unit, the section area being arranged within the planar shape of the building of the apartment building, within a range that fits within the planar shape of the building;
calculating an evaluation value for the expanded divided area based on an evaluation criterion related to an area of the divided area, the evaluation criterion being determined in advance in association with the type of the section;
Run the following on your computer :
The room types include at least a living room including a living room or a bedroom, and a corridor;
The evaluation criteria for the area of the area are as follows: the lower the corridor ratio, which is the ratio of the corridor to the planar shape of the dwelling unit, the higher the evaluation;
The types of the sections include at least a dwelling unit and a common area including a common corridor, a common staircase, or a common elevator;
The evaluation criteria for the area of the partitioned area are as follows: the lower the common area ratio, which is the ratio of the common area to the planar shape of the building, the higher the evaluation.
