Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If practical physical testing is used to determine reference data, then measurement precision is improved, but loss of time and productivity deteriorate due to extensive testing requirements
Solution Approach 1:
The patent applies preliminary action by computing reference data using strength analysis during the design phase, before the actual device is built or tested. This allows reference data to be prepared in advance, eliminating the need for extensive physical testing later while maintaining accuracy through computational methods.
Solution Approach 2:
The patent uses a design model as a copy of the actual device to perform strength analysis. This virtual copy allows reference data to be generated computationally without needing to physically test the real device, thereby saving time while maintaining measurement precision through accurate modeling.
2Reliability
If extensive physical testing is conducted to produce reference data, then reliability is improved, but device complexity and manufacturing difficulty worsen
Solution Approach 1:
The patent replaces the mechanical physical testing system with a computational strength analysis system. Instead of conducting physical tests on actual devices, the system uses computer-based strength analysis on design models, reducing physical complexity while maintaining reliability through accurate computational methods.
Solution Approach 2:
The patent uses a virtual design model copy to perform strength analysis, eliminating the need for complex physical testing setups. This virtual modeling approach simplifies the overall system complexity while maintaining reliability through accurate computational simulation of device behavior.
3Productivity
If design data and strength analysis are used to compute reference data, then productivity is improved, but measurement precision may worsen without physical validation
Solution Approach 1:
The patent performs strength analysis during the design phase to compute reference data in advance, dramatically improving productivity. The computational approach allows rapid generation of reference data without waiting for physical tests, while maintaining precision through sophisticated strength analysis methods applied to detailed design models.
