Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional compression spring shock absorbers are used, then shock absorption function is provided, but structure becomes complex and manufacturing cost increases
Solution Approach 1:
The shock absorber is divided into two rotating arms connected by a torsion bar spring, where each arm can rotate independently around fixed axes. This segmentation allows the shock absorption function to be achieved through the relative rotation between arms, simplifying the overall structure compared to traditional compression spring designs while maintaining effective vibration absorption.
Solution Approach 2:
The patent replaces the traditional compression spring mechanical system with a torsion bar spring system. Instead of using linear compression and extension movements, the invention uses torsional deformation of the bar spring during relative rotation of the arms, providing a simpler mechanical configuration that achieves the same shock absorption purpose.
2Ease of manufacture
If traditional shock absorbers with fixed stroke are used, then manufacturing is simplified, but adaptability to different road conditions deteriorates
Solution Approach 1:
The shock absorber incorporates adjustable stroke capability through the ability to modify the included angle between the two rotating arms. By changing this angle, the effective stroke of the shock absorber can be adjusted to suit different road conditions and rider preferences, while the basic manufacturing process remains simple and the fundamental structure is maintained.
