Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manufacturing information is created manually for each design proposal, then accuracy of manufacturing information is improved, but time and effort required increases significantly
Solution Approach 1:
The system performs preliminary action by pre-processing CAD model data into standardized formats and pre-calculating similarity metrics for multiple design proposals simultaneously. This allows manufacturing information to be estimated in advance before final design decisions are made, reducing the time required for each individual proposal while maintaining accuracy through systematic comparison with historical data.
Solution Approach 2:
The system creates accurate copies of manufacturing information from historical data by extracting and adapting proven manufacturing processes, materials, and parameters from past successful designs. These copied information are then customized to match the specific requirements of new design proposals, ensuring accuracy while significantly reducing the time and effort needed to create manufacturing information from scratch.
2Productivity
If manufacturing information is estimated using only shape similarity, then processing speed is improved, but accuracy of manufacturing information estimation deteriorates
Solution Approach 1:
The system applies parameter changes by transforming the CAD model data into standardized numerical parameters that capture both geometric and manufacturing attributes. This allows the similarity calculation to efficiently process multiple parameters simultaneously, maintaining high processing speed while improving estimation accuracy by considering comprehensive design characteristics beyond simple shape matching.
Solution Approach 2:
The system segments the manufacturing information estimation process into distinct computational stages: CAD data extraction, parameter normalization, similarity calculation, and information synthesis. This segmentation enables parallel processing of multiple design proposals and efficient reuse of calculation results, maintaining high productivity while ensuring accurate estimation through systematic multi-parameter comparison.
3Reliability
If comprehensive manufacturing information is created for evaluation, then quality of design evaluation is improved, but complexity of information management increases
Solution Approach 1:
The system implements universality by creating a multi-functional platform that simultaneously performs CAD data management, similarity calculation, manufacturing information estimation, and evaluation quality assessment. This unified system handles diverse manufacturing information types (materials, processes, parameters) through standardized interfaces, improving evaluation quality while reducing information management complexity through integrated processing.
