Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If connection terminals are inserted into inserting grooves without guide structures, then the assembly process is simple, but the insertion accuracy is poor causing terminal deformation
Solution Approach 1:
The patent applies preliminary action by providing guide grooves and guide projected streaks before the actual insertion of connection terminals. These guide structures are pre-formed on the terminal inserting member and terminal holding member respectively, ensuring that terminals are correctly positioned and aligned before insertion occurs, thereby preventing deformation while maintaining assembly simplicity
Solution Approach 2:
The patent uses guide grooves and guide projected streaks as intermediary elements between the connection terminals and inserting grooves. These intermediary guide structures facilitate accurate alignment and insertion by providing a controlled path for the terminals, reducing direct contact forces that could cause deformation while improving insertion precision
2Reliability
If connection terminals are inserted without positioning structures, then the assembly operation is easy, but the connection reliability is poor due to deformation
Solution Approach 1:
The guide grooves and guide projected streaks are pre-formed on the components before assembly, establishing correct positioning paths in advance. This preliminary positioning action ensures that during assembly operations, the connection terminals naturally follow the correct path into the inserting grooves, improving connection reliability without complicating the assembly process
Solution Approach 2:
The guide structures serve as intermediary positioning elements that mediate between the assembler's actions and the final terminal insertion. They provide tactile and geometric guidance during the assembly operation, ensuring reliable connections while keeping the assembly process straightforward and easy to perform
