Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wheel fatigue testing is conducted without suspension mounting, then testing simplicity is improved, but test accuracy deteriorates due to lack of suspension buffering effect
Solution Approach 1:
The patent combines the wheel testing system with a suspension mounting structure, merging previously separate testing components into an integrated system. The suspension assembly is mounted on the testing equipment, allowing simultaneous testing of both wheel and suspension components, thereby incorporating the suspension buffering effect into the wheel fatigue testing.
Solution Approach 2:
The testing equipment is designed with universal functionality to accommodate both wheel testing and suspension mounting. The equipment can mount suspension assemblies and wheels simultaneously, making it a multi-functional test system that serves multiple testing purposes while improving test accuracy through comprehensive component inclusion.
2Measurement precision
If axis coupling road simulation test is conducted with suspension mounting, then test accuracy is improved, but device complexity and test cost increase
Solution Approach 1:
The testing system is segmented into modular components including a mounting base, inclination angle regulation assembly, rotation angle regulation assembly, and vertical load loading assembly. Each module can be independently configured and adjusted, allowing the system to achieve complex testing capabilities while maintaining operational simplicity through modular design.
Solution Approach 2:
The equipment incorporates dynamic regulation mechanisms including inclination angle regulation, rotation angle regulation, and vertical load loading capabilities. These dynamic features allow the system to adapt to different testing scenarios and simulate various road conditions, improving test accuracy without requiring a completely complex static structure.
3Measurement precision
If finished automobile road test is conducted, then test accuracy is improved, but development time and cost increase
Solution Approach 1:
The patent creates a simplified copy or model of the actual road testing conditions in a controlled laboratory environment. By replicating the suspension buffering effect and loading conditions through the mounting base and regulation assemblies, the system provides an accelerated test that mirrors real-world performance without requiring actual road testing of finished automobiles.
Solution Approach 2:
The testing system enables preliminary verification of wheel and suspension fatigue durability before actual road testing is performed. By conducting these tests in advance using the specialized equipment, development issues can be identified and resolved beforehand, reducing the time and cost of subsequent road testing and vehicle development.
