Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal includes a fastening part and a metal joining part with different coupling methods, then conduction reliability between the first conductive member and the second conductive member is enhanced, but deformation may still occur under external vibrations or impacts
Solution Approach 1:
The terminal is divided into multiple functional parts: a fastening part for mechanical fixation, a metal joining part for electrical connection, and a positioning part for structural alignment. Each part performs a specific function to collectively enhance both conduction reliability and structural stability under external stress.
Solution Approach 2:
The positioning part is designed in advance to prevent deformation before it occurs. By providing a positioning part that extends from the first conductive member and contacts the second conductive member, the structure is pre-configured to resist deformation from external vibrations or impacts before they occur.
2Ease of manufacture
If the crimp part is crimped to the third conductive member without a positioning part, then the manufacturing process is simpler, but undesired deformation occurs on the crimp part
Solution Approach 1:
The positioning part acts as an intermediary element between the first and second conductive members. It provides a reference surface for positioning the second conductive member during the crimping process, ensuring accurate positioning without complicating the overall manufacturing process.
Solution Approach 2:
The positioning part is prepared in advance on the first conductive member to guide the positioning of the second conductive member before crimping occurs. This preliminary positioning action ensures that the crimp part is accurately positioned and prevents undesired deformation during the crimping process.
3Device complexity
If multiple conductive members are connected without a positioning part, then the device structure is simpler, but the connection reliability between the terminal and other conductive members deteriorates
Solution Approach 1:
The terminal structure is segmented into distinct functional components: the first conductive member, the second conductive member, and the positioning part that connects them. This segmentation allows each component to perform its specific function while maintaining overall structural simplicity and enhancing connection reliability.
Solution Approach 2:
The positioning part is designed and positioned in advance to establish proper alignment between the first and second conductive members before final connection. This preliminary positioning action ensures reliable connection without requiring complex structural designs or additional alignment procedures.
