Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional horn control systems use a long control stroke with multiple components, then the control mechanism can provide adequate shock absorption, but the device complexity increases and the control response time increases
Solution Approach 1:
The patent combines the shock-absorbing function and elastic return function into a single deformable part made from elastomer material. This deformable part is arranged between the base part and the control device, eliminating the need for separate shock absorbers and return springs, thus reducing component count while maintaining reliability
Solution Approach 2:
The deformable elastomer part performs multiple functions simultaneously: it acts as both the shock-absorbing means and the elastic return means. This multi-functional component reduces device complexity by eliminating redundant parts while ensuring adequate shock absorption and return force generation
2Force
If traditional horn control systems use a long control stroke, then the control mechanism can provide adequate return force, but the control detection time increases and the clearance between parts increases
Solution Approach 1:
The patent changes the key parameter from control stroke length to elastomer material properties and pre-compression level. By adjusting the elastomer characteristics and pre-compression, adequate return force is generated with a small control stroke, enabling rapid control detection and reducing clearance between parts
3Stability of the object's composition
If traditional horn control systems use multiple components for guidance and positioning, then the control mechanism can provide stable positioning, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent integrates guidance and positioning functions into the base part structure, which provides guiding means for the control device. This eliminates the need for separate guidance components while maintaining positioning stability, thereby simplifying manufacturing
