Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a toothed disc arrangement is used for torque transmission, then structural simplicity is maintained, but adjustment precision and sensitivity are insufficient
Solution Approach 1:
The patent replaces the toothed disc mechanical engagement system with a brake system utilizing friction between a brake pad and brake disc. This substitution enables stepless adjustment of the coupling distance through rotational movement of the coupling rod, achieving sensitive and precise distance control while maintaining structural simplicity. The friction-based brake system allows continuous position adjustment unlike the discrete toothed disc engagement.
2Ease of operation
If the coupling rod is rotatably connected to both coupling members, then ease of operation is improved, but stability and prevention of undesired distance changes deteriorates
Solution Approach 1:
The patent introduces a brake pad as an intermediary element between the coupling rod and the first coupling member. This brake pad, in contact with a brake disc, provides a braking torque that acts as a stabilizing force to prevent undesired rotational movements of the coupling rod. The intermediary brake system allows the coupling rod to remain rotatably connected for ease of operation while simultaneously providing the necessary stability through friction-based torque transmission.
3Manufacturing precision
If a brake system with frictional engagement is introduced, then adjustment sensitivity is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the brake system components (brake pad, brake disc, and actuation mechanism) with the existing coupling rod assembly. The brake disc is integrated into the coupling rod structure, and the brake pad is positioned to contact it, combining multiple functions into a unified assembly. This merging approach achieves precise stepless adjustment capability while minimizing the increase in manufacturing complexity by reusing existing structural elements and integrating new components efficiently.
