Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light valve modules in projectors face inefficiencies in heat dissipation due to the weight of heat dissipation fin sets, which can cause separation from the heat dissipation plate and reduce heat dissipation efficiency.
Innovation Solution
A light valve module design incorporating a heat dissipation structure with a supporting component that includes an extending and supporting portion, where the heat dissipation structure is suspended and supported by the supporting portion, maintaining contact with the light valve element and enhancing heat dissipation efficiency even with heavy heat dissipation structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heat dissipation fin set is made heavier to improve heat dissipation capability, then the heat dissipation efficiency is improved, but the heat dissipation plate and digital micro-mirror device may separate due to weight, which reduces heat dissipation efficiency
Solution Approach 1:
The patent applies preliminary action by pre-establishing a supporting structure (extending portion with supporting portion) that proactively bears the weight of the heat dissipation fin set before any separation can occur. This preventive support mechanism ensures that even heavy heat dissipation structures are held in position, maintaining continuous contact between the heat dissipation plate and light valve element throughout operation.
2Device complexity
If the heat dissipation fin set is merely supported by heat pipes without additional support structures, then the device complexity is reduced, but the heat dissipation structure may separate under weight, reducing heat dissipation efficiency
Solution Approach 1:
The patent introduces an intermediary supporting structure (the extending portion with supporting portion) that acts as a mediator between the heat dissipation fin set and the main casing. This intermediate support component specifically bears the weight of the heat dissipation structure and transmits it to the main casing, preventing separation while maintaining a relatively simple overall device structure.
