Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional blocking elements are used to limit connector movement, then connection reliability is improved, but device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
The patent combines multiple blocking functions into a single coupling element with integrated protuberances. The first and second protuberances on the coupling element simultaneously provide blocking in perpendicular directions, eliminating the need for separate blocking elements and reducing overall connector complexity while maintaining reliability
Solution Approach 2:
The coupling element is segmented into distinct functional zones: a coupling portion for engagement and a blocking portion with protuberances for vibration resistance. This segmentation allows each part to perform its specific function optimally while simplifying the overall structure compared to multiple separate components
2Reliability
If multiple separate blocking elements are added to resist vibrations in different directions, then vibration resistance is improved, but device complexity and parts quantity increase
Solution Approach 1:
Multiple blocking functions are merged into the coupling element's protuberances. The first protuberance blocks movement in a first direction while the second protuberance blocks movement in a second perpendicular direction, providing multi-directional vibration resistance with a single integrated component rather than multiple separate parts
Solution Approach 2:
The coupling element serves multiple functions simultaneously: mechanical coupling of connectors, blocking movement in multiple directions, and guiding insertion. This multi-functionality eliminates the need for separate blocking elements and reduces the total number of parts in the connector assembly
3Stability of the object's composition
If rigid blocking elements are used to prevent disconnection, then connection stability is improved, but resistance to external forces decreases
Solution Approach 1:
The blocking element transitions from a rigid structure to a flexible structure. The flexible protuberances on the coupling element can deform under external forces, allowing the connector to absorb mechanical shocks and vibrations without damage, while still maintaining stable connection through the receptacle engagement
