Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring clamp terminal is used to clamp the pole terminal, then connection stability is improved, but assembly space increases and connector size cannot be reduced
Solution Approach 1:
The invention extracts the spring clamp terminal from the connector structure and replaces it with a simplified pole terminal design. The female connector directly receives and secures the male pole terminal through geometric constraints (insertion groove and positioning strip) rather than elastic clamping, eliminating the need for spring components and reducing overall connector volume.
Solution Approach 2:
The invention changes the connection mechanism from elastic deformation (spring clamping) to rigid geometric constraint (insertion groove and positioning strip). This parameter change allows the connector to achieve stable connection without requiring the additional assembly space needed for spring terminals, thereby reducing connector size while maintaining connection reliability.
2Power
If dual poles are used for connection, then current transmission capability is improved, but dimensional accuracy requirements increase and contact reliability decreases
Solution Approach 1:
The invention introduces an intermediary positioning strip that mediates between the dual pole terminals. This positioning strip acts as a reference element that guides the male pole terminal into correct alignment, compensating for dimensional variations and ensuring reliable contact without requiring extremely tight manufacturing tolerances on the poles themselves.
Solution Approach 2:
The positioning strip performs preliminary alignment action before the actual electrical contact is established. By pre-positioning the male pole terminal correctly through the insertion groove and positioning strip, the system ensures proper alignment is achieved before contact pressure is applied, reducing sensitivity to dimensional inaccuracies.
3Ease of manufacture
If the connector design is simplified to reduce size, then manufacturing cost decreases, but connection stability and fault tolerance deteriorate
Solution Approach 1:
The invention segments the connection function into distinct geometric elements: the insertion groove for reception, the positioning strip for alignment, and the pole terminals for electrical contact. This segmentation allows each component to be simple and easy to manufacture while collectively providing stable connection and fault tolerance through their coordinated geometric relationships.
