Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shock absorber mounting angle is fixed, then the structure is simple and reliable, but the shock absorber efficiency cannot be optimized in response to varying vehicle body height and wheel movement
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed mounting structure into a dynamic adjustable one. The shock absorber mounting angle is made variable through a driving unit that can adjust the angle in response to vehicle body height and wheel movement conditions, allowing the system to adapt to changing operating conditions while maintaining structural integrity
Solution Approach 2:
The patent implements parameter changes by varying the mounting angle parameter of the shock absorber based on detected vehicle body height and wheel movement. The driving unit modifies the angular parameter dynamically, enabling the shock absorber to operate at optimal angles for different suspension states, thereby improving efficiency without requiring complete structural redesign
2Productivity
If a driving unit is added to adjust the shock absorber mounting angle, then the shock absorber efficiency is improved, but the device complexity and number of components increase
Solution Approach 1:
The driving unit is designed with multi-functionality to justify its addition. It not only adjusts the shock absorber mounting angle but also integrates with the existing suspension system to respond to vehicle body height changes and wheel movement, effectively performing multiple functions including angle adjustment, vibration control optimization, and adaptation to different road conditions
Solution Approach 2:
The system incorporates feedback mechanisms where sensors detect vehicle body height and wheel movement conditions, and this information is used by the driving unit to automatically adjust the shock absorber mounting angle. This closed-loop feedback control enables the system to maintain optimal performance without requiring complex manual intervention or overly sophisticated control systems
3Reliability
If the shock absorber mounting angle is optimized for specific vehicle height, then vibration attenuation is improved, but the system cannot adapt to varying vehicle height conditions
Solution Approach 1:
The system transitions from a static mounting angle design to a dynamic one that continuously adapts to vehicle body height changes. The driving unit adjusts the shock absorber angle in real-time based on detected height variations, ensuring optimal vibration attenuation performance across different suspension states and road conditions
Solution Approach 2:
The system uses feedback from vehicle body height sensors to automatically adjust the shock absorber mounting angle. This feedback mechanism ensures that the system maintains reliable vibration attenuation performance across varying vehicle height conditions by continuously optimizing the mounting angle based on actual operating parameters
