Electrical Connection Box Tool Holding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connection boxes face difficulties in reliably detaching tools from the housing, especially when the tools are held in place, and the tool holding portions may deform, making detachment challenging.
Innovation Solution
The electrical connection box design includes a housing with a tool holding portion that features a holding main body, a rotation regulating portion, and a protrusion, which work together to securely hold and then detach the tool by regulating rotation and providing additional structural support to prevent deformation during the detachment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tool is strongly held in the housing during vehicle operation, then the tool remains securely in place, but the tool becomes difficult to detach from the housing
Solution Approach 1:
The tool holding portion is designed with elastic deformation capability, allowing it to dynamically adapt between holding and detachment states. The holding portion deforms elastically to release the tool when detachment force is applied, transitioning from a rigid holding state to a flexible release state.
Solution Approach 2:
The tool holding portion is pre-designed with a specific deformation characteristic that allows it to automatically return to its original shape after deformation. This preliminary design ensures that the holding portion can reliably return to its holding position after being deformed during detachment, without requiring additional resetting actions.

AI summary
An electrical connection box includes a housing, a tool and a tool holding portion. The tool includes a main body in which a holding hole is formed, and a pinching portion. The tool holding portion includes a holding main body, a rotation regulating portion and a protrusion protruding on an opposite side from a side of the rotation regulating portion with the holding main body interposed therebetween. The protrusion is formed to face an opposite side from a side of the pinching portion with the holding hole interposed therebetween in the main body in an insertion direction in the holding state, and comes into contact with the main body in a state in which the pinching portion is positioned in a pulling direction compared to a position of the main body from the holding state.
