Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional connector structure is used, then the assembly is simple, but contact defects occur between cable and connector
Solution Approach 1:
The terminal is designed to be pivotable rather than fixed, allowing it to dynamically adjust its position during cable insertion. The cam mechanism provides dynamic control over the terminal's movement, enabling reliable contact establishment through controlled motion rather than static positioning.
Solution Approach 2:
The cam acts as an intermediary mechanism between the cable insertion action and the terminal contact establishment. By introducing this intermediate element, the system transforms simple cable insertion into controlled terminal movement, ensuring reliable contact without requiring complex direct coupling.
2Ease of operation
If additional actuators are added for cable fastening, then the fastening control is improved, but the device complexity increases
Solution Approach 1:
The cam mechanism is designed to automatically perform the fastening function through its geometric shape and rotational motion. The cam profile itself provides the necessary control characteristics without requiring external actuators, allowing the mechanism to serve its own control needs.
Solution Approach 2:
The cam mechanism controls cable fastening by changing the positional parameter of the terminal through rotational motion. By varying the cam rotation angle, the terminal position is automatically adjusted, providing controlled fastening without additional actuating components.
3Adaptability or versatility
If the substrate area is maximized for component placement, then the connector functionality is complete, but the usable area is reduced
Solution Approach 1:
The connector is divided into functional modules: the pivotable terminal section and the cam mechanism section. This segmentation allows each component to perform its specific function efficiently, reducing the overall space required compared to a monolithic connector design.
Solution Approach 2:
The cam mechanism is positioned to utilize the same spatial envelope as the terminal assembly. The cam rotates within the housing space already required for the pivotable terminal, nesting the fastening function within the existing structural footprint rather than requiring separate dedicated space.
