DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 to FIG. 12 are views showing a thought formation screen of the design thinking support method according to the present embodiment. Here, an example of designing a machine for compacting snow at a ski resort will be described. A thought formation screen that enumerates the requirements necessary to realize the target machine, a thought formation screen that classifies the requests into functions and constraints that hinder or affect the realization of the functions, and specifies the functions and constraints Thinking formation screen that develops into the concept space by using the method of (2) and arrives at the mechanism, and the thought formation screen that draws the mechanism that came up with the mechanism diagram and the structure from the mechanism diagram. Each thought formation screen is operated by a computer etc. It is processed and displayed on the display device.

FIG. 1 is a view showing a thought forming screen for inputting various design requirements of a designer to be designed.
Here, various requirements necessary for realizing a machine for compacting snow at a ski resort are listed and displayed.

Specifically, as shown in the figure, "I want to crush the bumps that can be used as a ski slope. I want to crush fresh snow and crush snowdrifts. I want to climb a slope with a maximum slope of 25 degrees. Ice. I want to climb even if there is a burn, I want to drive at night until 8:00 in the morning when the lift business starts, -3 in winter morning
0 ° C. It does not emit avalanche sound or impact. Does not sink or get stuck in fresh snow. And the like, and enumerate and input the functions that the target machine should fulfill, what the designer wants to do, what he wants to know, what he is having trouble with, etc.

FIG. 2 shows the requirements (functions on the plus side) to be fulfilled by the machine to be designed and influences on the realization of the functions by organizing the requirements enumerated on the thinking formation screen of FIG. It is a figure which shows the thought formation screen displayed separately with the constraint condition (function of the minus side) which prevents realization.

Here, as shown in the figure, the function is classified as "Crush the bumps on the slopes, crush the fresh snow, crush the snowdrifts, climb the slope of 25 degrees, climb the ice barn". Driving at night. Works at -30 ° C. No impact. No sinking in fresh snow. "

Next, FIGS. 3 to 7 are diagrams showing the process of expanding each group of functions and constraints displayed in FIG. 2 into a conceptual space to arrive at a mechanism.

FIG. 3 shows a group of functions and constraints separated in FIG. 2 in which each function is surrounded by a first display frame displayed by an elongated solid line circle or the like, and each constraint is defined by an elongated 2 A function group surrounded by a second display frame displayed by a double circle or the like, and furthermore, functions having similar meanings and constraints are brought close to each other and connected by a double line, and further, a function group connected by a double line; It is a figure which shows the thought formation screen which displays the whole constraint condition group by enclosing with a dotted line.

Here, as shown in the figure, "Squash the slopes", "Squeeze fresh snow", and "Crush the snowdrift" are functions of one synonymous group.
"Climb a 25-degree slope" and "Climb an ice-burn" are one synonymous group function, "Driving at night" and "Work at -30 ° C" are one synonymous group constraint. , "Do not generate impact" and "Do not sink in fresh snow" are classified and arranged as constraints of one group each.

By performing the classification and sorting process in this manner, similar functions and constraints are clarified, and what are really necessary functions and constraints are clarified.

Next, FIG. 4 summarizes the concept of each function and each constraint in each group with respect to each function and each constraint in each group formed on the thinking formation screen shown in FIG. FIG. 9 is a diagram showing a thought formation screen that is expressed by simplified or standardized functions and constraints and that is connected to clarify the relationship between each function and each constraint expressed by simplification or standardization.

Here, by expressing each function and each constraint condition in each group in a simplified or standardized manner, a function and a constraint condition higher than these functions and constraint conditions are displayed on a thinking formation screen described later. It is easy to reach.

In the same figure, the function of one synonymous group consisting of "crushing the slope of the slope", "compacting the fresh snow" and "crushing the snowdrift" is simplified as "stepping on the snow". Or expressed in standardized functions,
The function of one synonymous group consisting of "climbing a 25-degree slope" and "climbing an ice-burn" is expressed as a simplified or standardized function of "climbing a hill" and "driving at night". And "It can work even at -30 ° C." Is expressed as a simplified or standardized constraint of "use at low temperature".

When standardizing functions and constraints, a thesaurus (synonym dictionary) prepared in advance is used. If it is possible to standardize the terms to be commonly used in engineering here, a technology-related diagram prepared separately (a diagram that links words that designers generally associate with each other, also called a mind map) or design knowledge By using this database, it is possible to derive a mechanism necessary for realization and prevention and advice for selecting the mechanism.

Further, in the simplified or standardized functions, between the constraints, and between the functions and the constraints, mutually influencing relationships are connected by solid lines, and conflicting relationships are established. Are linked by ← → (both ends are solid arrows), and those having a higher / lower relationship are linked by → (solid arrows from upper to lower).

Here, the function "step on snow", the constraint condition "use at low temperature" and the constraint condition "do not generate impact"
Indicate that the function “step on snow” and the constraint condition “do not sink in snow” are in conflict with each other. In addition, the function "climb up the slope" and the constraint condition "use at low temperatures" and the constraint condition "do not generate an impact" are mutually related, and the function "climb up the slope" and the constraint condition "do not sink in the snow" Are in conflict.

The thinking formation screen clarifies the correlation between the simplified or standardized functions, the respective constraints, and the correlation between the respective functions and the respective constraints.

FIG. 5 is a view showing a thought forming screen for assuming functions or constraints which are simplified or standardized in FIG. 4 and which have a superordinate relation to each other.

Here, by newly setting functions or constraints that are in a higher-order relationship, it is possible to accurately arrive at a mechanism described later.

At the time of extraction, in the same manner as that performed on the thinking formation screen shown in FIG. 4, a newly conceived upper-level function and the like are included, between each function, between each constraint, and between each function and each constraint. Connect between. The operation of the conception or connection of the higher-level function or the like is performed by moving the function enclosed by the first display frame or the constraint condition enclosed by the second display frame to an arbitrary position together with the connection previously displayed. It is good to do while doing.

As shown in the figure, the function "stepping on the snow" is superordinated to "increase the contact pressure", and the two are connected. In addition, as the upper function of the function "climbing the slope", we came up with "increase the frictional force", connected the two, and further increased the function "increase the frictional force" and the higher function "increase the contact pressure""Do". In addition, the function "contact pressure is reduced", and the function "contact pressure" is in conflict with the function "contact pressure", which is in the upper level of the constraint condition "does not sink". To be larger. "

Further, a warning is automatically given to a function or a constraint condition having a conflict, and a hint for resolving the conflict is displayed.

FIG. 6 is a diagram showing a thought formation screen which is based on the thought formation screen shown in FIG. 5 and arrives at a mechanism satisfying each function and each constraint condition.

The mechanism is constructed so that the influencing and conflicting relations between the functions and the constraints indicated by the links are eliminated. The mechanism is surrounded by a third display frame displayed as a solid-line rectangle or the like, and in the case where functions are displayed as a mechanism, a second display frame surrounds the first display frame where functions are displayed. Enclose and display.

In the thought forming screen shown in FIG. 5, a mechanism where a problem is likely to occur is considered for the time being. In the thinking forming screen shown in FIG. 5, the conflicting "increase the contact pressure" and "decrease the contact pressure" As for “do”, as shown in the thought formation screen of FIG. 6 from the “contact pressure” that is in a vertical opposition to the ground from the second hint “change the direction of action” displayed in the hint, Raising the viewpoint of "snowing" in the direction parallel to the ground, a mechanism "caterpillar" for a series of functions of "increase contact pressure", "increase friction", and "climb up slope" The mechanism "blade" is conceived for each function or constraint condition of "snow" and "do not sink". In addition, it is assumed that a mechanism cannot be imagined at this time for a series of functions of “increase contact pressure” and “step on snow”, and the function “step on snow” is displayed as a mechanism. Even if the influential or conflicting relations between functions and constraints are resolved, if you want to keep the relations, if you want to keep the relations, connect the affecting relations with dotted lines, and indicate the conflicting relations with arrows at both ends. Displayed by connecting with dotted line. For example, there was a conflict between the function "step on snow" and the function "does not sink". By using the "blade" to realize each function with an independent mechanism, the conflict has been resolved, but it has been clearly shown that there was once a conflict by connecting with ←… →.

FIG. 7 is a diagram showing a thought formation screen that further advances the thinking from the thought formation screen shown in FIG. 6 and arrives at a mechanism that satisfies each function and each constraint.

Here, in the thought forming screen shown in FIG. 6, the function "step on snow" is displayed as a function "rolling on the snow" while the function "step on snow" is memorized without thinking about the function. Is displayed.

FIG. 8 is a diagram showing a thinking formation screen for drawing a mechanism diagram and a structural diagram based on the thinking formation screen shown in FIG.

Here, a mechanism diagram is drawn on the basis of each of the "blade", "caterpillar", and "roller" mechanisms conceived on the thinking formation screen of FIG. 7, and then a structural diagram is drawn on the basis of this mechanism diagram. I'm drawing. Matters deemed necessary in the process of drawing these mechanical diagrams and structural diagrams will be left as memos. Here, as a memo of the structural drawing, it is noted that a machine having the mechanisms "blade", "caterpillar", and "roller" has a "defect that can only move forward".

FIG. 9 is a view showing the thought formation screen which returns to the thought formation screen of FIGS. 5 and 6 and thinks about a mechanism different from the mechanism obtained in the thought formation screen of FIG. .

Here, the mechanism "caterpillar" is conceived as a mechanism that satisfies both the function "step on snow" and the function "climb up a slope", and the function "generates lift".
"Ski" has been conceived as a mechanism that satisfies a series of functions of "generate lift" and "do not sink in the snow." However, the mechanism "caterpillar" has a two-to-one relationship with the function. In this state, the warning of the interference design is displayed. If the functions or constraints have an interference relationship with each other, a warning is automatically issued and a hint for eliminating interference is displayed.

FIG. 10 is a diagram showing a thinking formation screen in which a mechanism diagram and a structural diagram are drawn based on the thinking formation screen shown in FIG.

Here, a mechanism diagram based on the mechanism "caterpillar" and mechanism "ski" conceived on the thinking formation screen of FIG. 9, and a structure diagram based on this mechanism diagram are drawn.

[0051] As a memo related to the mechanical diagram, "anything is possible if the board faces upward. Can the front of the caterpillar be turned upward?" As a memo related to the structural diagram, "This is also a drawback that it can only be advanced forward, May be
May be upside down. "

FIG. 11 is a diagram showing the thinking formation screen in which a new mechanism is considered, returning to the thinking formation screen of FIG. 5 again.

Here, two of the hints displayed to eliminate the interference relationship shown on the thought formation screen of FIG.
Select the second "Disassemble into lower-level mechanisms", disassemble the mechanism "caterpillar" to come up with the mechanisms "flat plate" and "Eisen", and further higher-level functions for the function "step on snow""Snowleveling" is conceived, and as a result, "plate" is conceived as a mechanism for a series of functions of "snow leveling" and "stepping on snow". In addition, the function "strike the ground" is conceived below the function "increase the friction force", and as a result, a series of functions of "increase the friction force" and "stab the ground" and the function "climb up the slope" To the mechanism "Eisen". Also, the constraint condition "Does not sink in snow"
As a result, a function "generates lift" is conceived, and as a result, a mechanism "wide plate" for the function "generates lift" and the constraint condition "does not sink in snow" is conceived. Each of these "plate", "Eisen", and "wide plate" mechanisms has a lower order relationship with respect to the mechanism "caterpillar".

The hints shown on the thinking formation screens in FIGS. 5 and 9 can be called thinking operations. In particular, the hints shown in FIGS. 5 and 9 are useful for solving design problems. Extremely effective. At this time, as hints, four arithmetic operations, function reversal, field visualization, conformal mapping,
It is preferable to use a known thinking operation method such as insertion, control exclusion, and time separation of the third substance, or a thinking operation method such as inversion of inside and outside, phenomenon conversion, prior separation, and a rule of technological evolution shown in TRIZ.

FIG. 12 is a diagram showing a thinking formation screen in which a mechanism diagram and a structural diagram are drawn based on the thinking formation screen shown in FIG.

Here, a mechanism diagram is drawn based on the respective mechanisms of “flat plate”, “cracker,” “wide board”, and “caterpillar” conceived on the thinking formation screen of FIG. 11, and further based on this mechanism diagram. I draw a structural drawing.

It should be noted that a memo relating to the mechanical diagram is "same as a spike tire", and a memo relating to the structural diagram is "a disadvantage that it cannot run on a snowy road".

As described above, by going through the thinking forming process of the design thinking support method of the present embodiment, it is possible to easily and accurately obtain the desired structure of the “machine for compacting snow at ski resorts”.

In each of the above figures, the display frames and connections surrounding the functions and constraints are not limited to those described above, and any shapes may be set and used as necessary. Is also good.

Next, a processing procedure for causing the design thinking support method according to the present embodiment to perform computer processing will be described with reference to flowcharts shown in FIGS.

First, in step 1, an object (a machine for compacting snow at a ski resort) designed on a thought formation screen
Input and display the requirements necessary for the realization of. Step 2
Then, based on the request obtained in step 1, the request is classified and displayed on the next thought formation screen into a function to be fulfilled by the object and a constraint condition that hinders the realization of this function. In step 3, the functions and constraints are displayed in different display frames on the next thought formation screen so that the functions and constraints obtained in step 2 are clearly indicated and the on-screen processing described later is easily obtained. Displayed with In step 4, on the next thought formation screen, the functions and constraints that are surrounded by the display frame obtained in step 3
Constraint conditions that are close to synonyms are displayed close together and connected. In step 5, the next thought formation screen is displayed in step 4
Between the functions having similar meanings and the constraint conditions having similar meanings obtained in the above are displayed as simplified or standardized functions and constraints. In step 6, on the next thought formation screen, for each function and each constraint obtained in step 5, those that have a mutually affecting relationship, those that have a conflicting relationship, and those that have a higher-lower relationship Are connected and displayed so that their relationship becomes clear. In step 7, a mechanism is conceived and displayed on the next thought formation screen based on the relationship diagram between the functions and the constraint conditions obtained in step 6. In step 8, the function obtained in step 7 is displayed on the next thought formation screen.
A mechanism diagram is drawn and displayed based on the relationship between the constraint conditions and the mechanism. In step 9, the structure of the object is drawn on the thinking formation screen of step 8 or the next thinking formation screen based on the mechanical diagram obtained in step 8. In step 10, when the structure of the desired object is obtained in the processing up to step 9, the processing is terminated. When the structure is not obtained, the process returns to the thinking formation screen of the above-mentioned arbitrary step and performs the processing again.

Although not described in the above-mentioned flowchart, in the processing of each step, it is free to return to the already processed step and perform the processing again.

In step 2, the functions to be fulfilled by the object and the constraints that hinder the realization of the functions are separated from the requests. Which of the listed requests is a function and which is a constraint. According to the viewpoint, there is a case in which there is a case, and there is little problem even if they are displayed in the same concept plane or concept space, including the mechanism, without strict classification.

In the above flowchart, in step 1, a request necessary for realizing the designed object is presented, and in step 2, the function that the object should fulfill the request and the function of this function are described. Although the constraints are classified into the constraints that hinder the realization, if the functions to be performed by the object and the constraints that hinder the realization of the functions are directly understood, step 1 may be omitted and step 2 may be started.
