Protector Assembly Structure for Incorrect Locking Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking mechanisms in protectors allow for incorrect insertion of the second locking part, leading to potential misassembly and reduced durability.
Innovation Solution
The assembly structure incorporates a protruding part that prevents incorrect insertion by visually indicating the error through the floating of the cover member when the second locking part is inserted into the wrong through hole, utilizing a flexible partition wall and a locking mechanism with a cantilevered locking piece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a flexible partition wall is used as the first locking part to enable the locking mechanism to function, then the locking mechanism can be simplified, but incorrect insertion becomes possible leading to assembly errors
Solution Approach 1:
The protruding part is positioned in advance on the first assembly member to guide the insertion of the second locking part. The contact wall on the second assembly member is designed to contact the protruding part before the locking operation, preliminarily indicating the correct insertion position and preventing incorrect insertion into the second through hole
Solution Approach 2:
The protruding part acts as an intermediary element between the first and second assembly members. It mediates the insertion process by providing a physical contact point that guides the second locking part into the correct position, preventing direct incorrect insertion into the wrong through hole
2Adaptability or versatility
If the second locking part is made flexible to enable insertion, then the locking mechanism becomes more adaptable, but incorrect insertion into the wrong through hole becomes more likely
Solution Approach 1:
The contact wall is designed to contact the protruding part in advance during the insertion process. This preliminary contact action occurs before the flexible second locking part can be inserted, providing early guidance that prevents incorrect insertion into the second through hole
Solution Approach 2:
The protruding part creates an asymmetric guidance structure that distinguishes the correct insertion path from incorrect paths. The contact wall is positioned asymmetrically to engage with the protruding part only when the second locking part is inserted into the first through hole, not the second through hole

Function Achieved in This Case
Prevents incorrect insertion by visually signaling the mistake, ensuring proper assembly and maintaining the assembly structure's durability by guiding the worker to reinsert the locking part correctly.

AI summary
A first assembly member has an orthogonal wall provided with an orthogonal flat face, a through hole provided in the orthogonal wall, a partition wall as a first locking part sectioning the through hole into a first through hole and a second through hole, and a protruding part caused to protrude from the orthogonal flat face. A second assembly member has a contact wall causing a tip to be in contact with the orthogonal flat face of a first periphery.
