Movable Bracket Electric Connection Box for Connector Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric connection boxes face difficulties in assembling connectors due to narrow opening dimensions and wire congestion, leading to cumbersome operations and reduced heat dissipation.
Innovation Solution
An electric connection box design featuring a bracket that can be moved between a near position and a fix position within the case main body, utilizing a rotation shaft and maintain device to facilitate easy connector fitting and prevent wire congestion, with strategically placed wire lead outlets to manage wire routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all connectors are fixed in the vicinity of the opening of the case main body, then workability of fitting connectors is improved, but electric wires are pushed out and gathered close causing interference and poor heat dissipation
Solution Approach 1:
The bracket is designed to be movable between a first position (near the opening) for assembly and a second position (retracted) for operation. This dynamic positioning allows connectors to be accessible during fitting while wires remain organized and spaced apart during use, resolving the contradiction between ease of connector fitting and heat dissipation.
2Object-affected harmful factors
If connectors are fixed at a deep area of the case main body, then electric wires are not pushed out, but workability of fitting connectors becomes much worse due to narrow opening
Solution Approach 1:
The bracket moves between a retracted second position (deep in the case) and an extended first position (near the opening). During assembly, the bracket is positioned near the opening to provide access for fitting connectors. During operation, it is retracted to properly manage wire routing. This dynamic approach resolves the contradiction between wire management and connector fitting accessibility.
3Ease of manufacture
If the bracket is fixed at a deep area, then wire routing is improved, but assembly operation becomes troublesome due to narrow opening dimension
Solution Approach 1:
The movable bracket enables the system to adapt its position based on the operational phase: during assembly, it extends near the opening to facilitate efficient connector fitting; during operation, it retracts to a deep position for proper wire routing. This dynamic adaptability resolves the contradiction between assembly efficiency and wire routing quality.
