Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current structure design support devices lack the ability to effectively identify and evaluate changes in the positional relationship between parts of a structure under external forces, making it difficult to optimize design changes such as increasing rigidity without resorting to trial and error.
Innovation Solution
A structure design support device that acquires evaluation point information to calculate the magnitude of changes in positional relationships between parts, allowing for the identification of areas requiring modification and the specification of optimal countermeasures, such as strengthening joining, to improve structural rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional structural analysis methods are used to obtain displacement or deformation mode information, then the analysis can be performed, but it is insufficient for making design changes according to specific purposes such as strengthening rigidity
Solution Approach 1:
The patent segments the structure into multiple parts and further segments the analysis into two distinct evaluation values: one for displacement mode and another for positional relationship changes between parts. This segmentation allows each evaluation value to serve specific design purposes, providing comprehensive information for different types of design changes without requiring trial and error.
Solution Approach 2:
The patent adds a new dimension to structural analysis by introducing the evaluation of positional relationship changes between parts as a separate evaluation value alongside the traditional displacement mode evaluation. This dimensional addition enables designers to assess both local deformation and inter-part positional changes, providing sufficient information for various design optimization purposes.
2Ease of operation
If designers use trial and error based on experience to detect portions to be changed, then design changes can be made, but it requires significant time and effort
Solution Approach 1:
The patent enables the structural analysis system to automatically identify portions requiring design changes by computing evaluation values that highlight areas with significant positional relationship changes. The system serves itself by providing objective, data-driven identification of critical areas, eliminating the need for designers to rely on subjective trial and error based on experience.
Solution Approach 2:
The patent introduces feedback mechanisms where evaluation values representing positional relationship changes are computed and used to identify portions requiring design changes. This feedback loop provides designers with actionable information about where to focus design modifications, significantly reducing the time and effort compared to trial and error approaches.
3Reliability
If traditional analysis methods are used, then only displacement or deformation mode information is obtained, but it is not possible to evaluate the possibility of improvement by strengthening joining to another part
Solution Approach 1:
The patent creates a multi-functional evaluation system where two evaluation values serve different but complementary purposes: one evaluates displacement mode for general structural performance, and the other evaluates positional relationship changes for assessing joining strengthening possibilities. This universal evaluation framework supports multiple design optimization strategies including rigidity enhancement, joining improvement, and shape optimization.
Solution Approach 2:
The patent performs preliminary evaluation of positional relationship changes between parts before design changes are implemented. By computing this evaluation value in advance, the system identifies portions where strengthening joining to other parts would be effective, allowing designers to plan and implement targeted design changes rather than relying on trial and error after design modifications.
