Electrical Connection Box Cover with Heat Dissipation Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical connection boxes with exposed power supply connection portions risk accidental touch and temperature rise due to heat accumulation when covered, as existing solutions either fail to prevent unintentional contact or effectively manage heat dissipation.
Innovation Solution
An electrical connection box design featuring a case with a cover that blocks the power supply connection portion from above, incorporating a hole portion for heat dissipation and detachable component holding, using a pair of wall portions to cover the connection portion from both sides, ensuring both safety and thermal management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply connection portion is covered to prevent unintentional touch, then safety is improved, but heat dissipation deteriorates causing temperature rise
Solution Approach 1:
The cover portion is designed with a hole portion at the location where heat needs to be dissipated, while other areas provide coverage for safety. This creates different local properties: areas with holes allow heat dissipation, while solid areas provide protection, resolving the contradiction between safety and heat dissipation.
2Temperature
If the power supply connection portion is exposed, then heat dissipation is improved, but the risk of unintentional touch increases
Solution Approach 1:
The cover portion provides coverage over the power supply connection portion to prevent unintentional touch, while incorporating a hole portion specifically positioned to allow heat dissipation. This local differentiation resolves the contradiction between safety and heat dissipation.
3Reliability
If a cover is added to protect the power supply connection portion, then safety is improved, but device complexity increases
Solution Approach 1:
The cover portion integrates multiple functions: it provides safety coverage, incorporates heat dissipation holes, and includes component holding portions for fuses. By merging these functions into a single integrated component rather than separate parts, the design improves safety without proportionally increasing complexity.
Solution Approach 2:
The cover portion serves multiple purposes simultaneously: protecting the power supply connection portion from unintentional touch, dissipating heat through hole portions, and holding components like fuses. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
