Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a concentrated point support system is used, then the structure is simple, but the supporting system is prone to damage and has poor stability
Solution Approach 1:
The supporting system is divided into multiple support points along the front bar rather than a single concentrated point. The front bar includes multiple rotating shafts distributed at different positions, which segment the support function to improve stability while maintaining structural simplicity.
Solution Approach 2:
Different sections of the front bar are equipped with rotating shafts at specific locations to provide localized support where needed. This allows the structure to have varying support characteristics at different points, improving overall stability without requiring complete restructuring.
2Reliability
If a higher cost rotating shaft system is used, then the service life and stability are improved, but the production cost of the car cover increases
Solution Approach 1:
The patent applies different material qualities to different rotating shafts based on their specific functional requirements. The large front bar rotating shaft uses durable materials for long service life, while other rotating shafts use cost-effective materials, achieving reliable performance without uniformly high costs across all components.
Solution Approach 2:
The patent varies the material parameters and structural parameters of rotating shafts according to their position and load requirements. By adjusting these parameters locally rather than using a uniform high-specification design throughout, the system achieves necessary reliability while controlling overall production costs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides improved stability and extended service life for the car cover's supporting system, while also lowering production costs through the use of different rotating shaft systems, making the car cover more economical.
Implementation Method 1
