Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are routed through conventional fixed structures, then cable routing is simple and device structure is stable, but cables are subject to mechanical stress, wear, and tension
Solution Approach 1:
The patent applies the dynamics principle by implementing a movable cable guide element that can shift position along a guidance path. This allows the cable routing to adapt dynamically to device movements, preventing mechanical stress and wear on high-voltage cables while maintaining structural stability. The cable guide element moves together with the cable, ensuring continuous protection during device operation.
Solution Approach 2:
The patent uses an intermediary approach by introducing a dedicated cable guide element as a mediator between the cable and the device structure. This intermediate component absorbs and distributes mechanical stresses, preventing direct transmission of forces to the cables. The guide element acts as a buffer that protects cables from tension and wear while maintaining their electrical function.
2Volume of moving object
If space-saving cable routing is implemented, then device size is reduced, but cables may experience bending stress and compression
Solution Approach 1:
The patent applies spheroidality by designing the cable guide element with a rounded, dome-shaped surface instead of sharp edges or corners. This curved geometry allows cables to bend naturally along the rounded path, distributing bending stresses evenly and preventing localized compression or damage. The smooth curvature enables space-efficient routing while protecting cables from mechanical harm.
3Stability of the object's composition
If cables are secured firmly to prevent movement, then cable positioning is stable, but cables experience friction and mechanical stress
Solution Approach 1:
The patent employs flexible shells by designing the cable guide element with a smooth, continuous surface that allows cable movement without rigid constraints. This flexible guidance structure maintains cable positioning stability while minimizing friction and mechanical stress through its ability to adapt to cable movements without creating sharp contact points or rigid restrictions.
