Connection Terminal Engaging Part Bending for Interference Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection terminals face interference issues with inclusively-fastening members due to the location of engaging parts and fixing pieces, leading to unstable attachment and potential size increases to avoid interference.
Innovation Solution
The connection terminal design features hollow and tubular wire connecting parts with flat plate attaching parts, where the engaging part is bent to be below the attaching part, and fixing pieces are bent to secure the edge of the superposed sheet, preventing interference with the inclusively-fastening member without increasing the terminal size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the engaging part is extended from the attaching part in parallel and the tip end part is bent upward, then the engaging part can be formed to engage with the engaged part, but the tip end of the engaging part interferes with the inclusively-fastening member mounted on the attaching part of the other terminal member
Solution Approach 1:
The engaging part is bent not only upward but also backward (in the direction opposite to the attaching part of the other terminal member). This two-dimensional bending creates a tip end that is positioned below the attaching part of the other terminal member, eliminating interference with the inclusively-fastening member while maintaining engagement functionality.
2Stability of the object's composition
If the fixing pieces are bent and crimped to grip the edge of the attaching part, then the attaching part is prevented from opening, but the fixing pieces interfere with the inclusively-fastening member mounted on the attaching part
Solution Approach 1:
The fixing pieces are bent not only backward but also downward, changing their position from the attaching part surface to below it. This dimensional change allows the fixing pieces to secure the attaching part edge while eliminating interference with the inclusively-fastening member mounted on the attaching part surface.
3Ease of manufacture
If the tip end of the engaging part is located above the mount surface of the inclusively-fastening member, then the engaging part can be easily formed, but the attitude of the inclusively-fastening member cannot be stabilized during mounting
Solution Approach 1:
The engaging part is bent backward and downward so that its tip end is positioned below the attaching part of the other terminal member and below the mount surface of the inclusively-fastening member. This positioning eliminates interference and allows the inclusively-fastening member to be mounted stably with its attitude properly stabilized.
