Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing terminal module requires increased working man-hours due to the need for bending the case, which complicates manufacturability.
Innovation Solution
The terminal module design includes a resiliently deformable coil spring and a case with side walls that accommodate the spring, featuring parallel divided wall portions and engaging portions on the terminal, allowing for improved manufacturability by eliminating the need for bending and enhancing assembly workability and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the case is bent to form the terminal receiving portion, then the terminal module achieves secure terminal retention, but the manufacturing complexity and working man-hours increase
Solution Approach 1:
The side wall is divided into multiple portions (first side wall portion, second side wall portion, third side wall portion) that can be independently formed and assembled. This segmentation eliminates the need to bend the entire case, reducing manufacturing complexity while maintaining secure terminal retention through the integrated structure of these portions.
Solution Approach 2:
The first side wall portion, second side wall portion, and third side wall portion are combined to form the complete side wall structure with the terminal receiving portion. This merging approach allows the structure to achieve secure terminal retention while being manufactured through simpler processes for each individual portion.
2Reliability
If the case is bent to form the terminal receiving portion, then the terminal module achieves secure terminal retention, but the production time increases
Solution Approach 1:
By segmenting the side wall into multiple formable portions that can be independently manufactured, the production process is streamlined. Each portion can be formed separately and then assembled, significantly reducing production time compared to bending the entire case while maintaining secure terminal retention.
Solution Approach 2:
The first side wall portion, second side wall portion, and third side wall portion can be prepared in advance as separate components. This preliminary preparation allows for parallel manufacturing processes and simplifies final assembly, reducing overall production time while ensuring secure terminal retention through the pre-formed structure.

AI summary
In a terminal module, a case includes a pair of side walls and a terminal member includes a first terminal relatively movable with respect to the pair of side walls. Each of the pair of side walls includes a first divided wall portion and a second divided wall portion. The first divided wall portion includes a first terminal receiving portion. The second divided wall portion includes a second terminal receiving portion. The first terminal includes a guided portion, a first engaging portion and a second engaging portion. The respective first divided wall portions of the pair of respective side walls are parallel to each other. The respective second divided wall portions of the pair of respective side walls are parallel to each other. At the first position, the guided portion of the first terminal is arranged between the first divided wall portion and the second divided wall portion.
