Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wire connection contacts are aligned parallel to the housing side surfaces, then plug insertion is facilitated, but electrical contact reliability with wires deteriorates
Solution Approach 1:
The wire connection contacts are oriented at a 45-degree angle relative to the housing side surfaces, transitioning from a parallel alignment to an angular orientation. This dimensional change in contact orientation enables both reliable wire contact (through the angled approach) and facilitates plug insertion (through the geometric configuration), resolving the contradiction between electrical contact reliability and ease of operation.
2Volume of moving object
If contact elements are arranged in a compact configuration, then device size is reduced, but manufacturing complexity increases
Solution Approach 1:
The contact elements are divided into modular components: a connecting web portion and contact limb portions that can be formed as separate features in the stamping process. This segmentation allows each component to be optimized independently for compactness while maintaining manufacturability through standard stamping techniques, reducing overall device volume without excessively increasing manufacturing complexity.
Solution Approach 2:
The contact elements utilize variable thickness parameters throughout their structure, with thinner sections in high-stress areas and thicker sections where structural support is needed. This parameter optimization enables compact design while maintaining structural integrity and ease of manufacture through controlled material distribution.
3Reliability
If contact limbs are positioned at 45 degrees to the housing surfaces, then electrical contact with wires is improved, but plug insertion difficulty increases
Solution Approach 1:
The contact limb geometry exhibits asymmetric design where the 45-degree angled portion provides optimal wire contact, while the opposing face and overall configuration are shaped to accommodate plug insertion. This asymmetric geometry allows the same contact element to fulfill both functions effectively, transforming the potential disadvantage of the 45-degree angle into an advantage through careful geometric optimization.
