Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protection covers for backlight modules are inefficient in dissipating heat, leading to component damage and operational issues due to delayed heat dissipation.
Innovation Solution
A protection cover design featuring a heat dissipation surface with heat dissipation holes and protruding sidewalls with vent holes, where the vent holes are arranged in equal spaces and have a larger diameter than the heat dissipation holes, forming effective air convection for timely heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation holes are disposed on the top plate, then heat dissipation function is provided, but heat dissipation efficiency is insufficient when large amounts of heat are gathered
Solution Approach 1:
The protection cover is segmented into multiple functional surfaces: the top plate with heat dissipation holes and the sidewall with vent holes. This segmentation allows heat to be dissipated through multiple pathways simultaneously, improving overall heat dissipation efficiency and preventing component damage from accumulated heat.
Solution Approach 2:
The invention transitions from a single-surface heat dissipation approach (top plate only) to a multi-dimensional approach by adding the sidewall with vent holes. This creates additional heat dissipation pathways in different spatial dimensions, enabling more effective heat removal from the protected components.
2Reliability
If the protection cover covers the components, then component protection is provided, but heat accumulates in the protection cover
Solution Approach 1:
Different regions of the protection cover are assigned different functions with corresponding structural characteristics. The top plate features heat dissipation holes for general heat release, while the sidewall incorporates vent holes specifically positioned to facilitate convective air flow. This local differentiation of structure and function enables effective heat dissipation while maintaining component protection.
