Electro-optical Panel Retaining Member Cooling Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electro-optical devices, such as liquid crystal projectors, face insufficient cooling efficiency, leading to potential overheating and degradation of the electro-optical material, which can result in poor display quality and increased risk of panel scratches during manufacturing.
Innovation Solution
The design incorporates a retaining member with a first portion that extends along one side of the electro-optical panel and a second portion that intersects this side, allowing cooling air to flow smoothly over the panel face, effectively dispersing heat and reducing the risk of scratches by minimizing contact with the panel during manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a retaining member is designed to hold the electro-optical panel, then the panel is securely retained, but the cooling air flow is blocked and cooling efficiency deteriorates
Solution Approach 1:
The retaining member is divided into multiple retaining portions (first retaining portion and second retaining portion) positioned at different locations. This segmentation allows cooling air to flow through gaps between the portions while still providing secure panel retention, thus resolving the contradiction between retention reliability and cooling efficiency.
Solution Approach 2:
Different portions of the retaining member have different properties: the first retaining portion has a first transparency to cooling air while the second retaining portion has a second transparency. This local differentiation optimizes both retention and cooling by allowing air flow through specific regions while maintaining structural support where needed.
2Reliability
If the retaining member contacts the panel face, then the panel is securely held, but the risk of panel scratches increases during manufacturing
Solution Approach 1:
The retaining member uses a configuration where cooling air flow serves as an intermediary mechanism. The air flow path is designed to pass through gaps in the retaining portions, allowing the air to cool the panel without the retaining member directly contacting the panel face, thus preventing scratches while maintaining retention.
Solution Approach 2:
The design utilizes cooling air flow (pneumatic element) as the primary cooling mechanism. The air flow passes through the retaining member structure, providing both cooling function and a non-contact retention method that avoids direct mechanical contact between the retaining member and panel face, reducing scratch risk.
3Temperature
If cooling air flows directly over the panel face, then cooling efficiency is improved, but the panel face is exposed to potential damage during manufacturing
Solution Approach 1:
The retaining member acts as a protective shell structure that allows cooling air to pass through its gaps. This shell configuration provides physical protection to the panel face during manufacturing while maintaining the cooling air flow path, thus resolving the contradiction between cooling efficiency and panel protection.

AI summary
An electro-optical device includes an electro-optical panel and a retaining member. The retaining member includes a first retaining portion that extends along a first side of the electro-optical panel and a second retaining portion that extends along a second side, the first side intersects a direction in which cooling air flows, the first retaining portion is formed to be flush with a panel face of at least one of a light incident side and a light emitting side of the electro-optical panel, and the second retaining portion is formed to protrude from at least one of the panel faces.
