Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connector is rotationally combined with an assembling-disassembling groove to enable simple operation and desired angle positioning, then the operation convenience is improved, but the shell becomes thick and durability is reduced due to repeated use and breakage probability
Solution Approach 1:
The rotational connector is divided into separate components: a rotating component with coupling convex portions and a fixing component with coupling concave portions. This segmentation allows each part to be simpler and more durable while maintaining the rotational functionality through the interaction of multiple smaller elements rather than a single thick connector.
Solution Approach 2:
The coupling convex portions are inserted into the coupling concave portions, creating a nested structure where the rotating component fits within the fixing component. This nesting approach eliminates the need for a thick shell while maintaining rotational capability through the interlocking geometry of the convex and concave coupling elements.
2Reliability
If high machining precision is applied to each component to ensure safe and convenient use, then the reliability is improved, but the processing and assembly difficulty increases
Solution Approach 1:
High precision is applied only to the critical coupling surfaces (coupling convex portions and coupling concave portions) where interlocking is needed, while other parts of the components can be manufactured with lower precision. This localized precision approach ensures reliable assembly and safe use without requiring high machining precision across all components, thereby reducing overall manufacturing difficulty.
Solution Approach 2:
The coupling convex portions and coupling concave portions are designed with asymmetric geometries that provide inherent guidance during assembly. The asymmetric shapes ensure proper orientation and alignment, making assembly intuitive and reducing the skill level required for manufacturing and assembly operations while maintaining reliable connection.
