Solution Overview

Problem

The existing electro-optical modules for projection-type display apparatuses have complex configurations with multiple frame bodies, leading to increased costs and assembly time due to the need for efficient heat dissipation and dust protection, which complicates the process and raises costs.

Innovation Solution

An electro-optical module with a simplified configuration that includes a frame with bent corner portions to accommodate the electro-optical panel, allowing for efficient heat release and dust protection, using overlapping transparent plates to prevent dust adherence and enhance cooling efficiency, and a flexible wiring board connection that optimizes heat dissipation by increasing the overlapping width with the frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If three frame bodies are used to hold the emitting side in the electro-optical panel for heat dissipation, then heat dissipation efficiency is improved, but device complexity and assembly time increase

Engineering Contradiction:

Improveheat dissipation efficiencyVSAvoidnumber of frame bodies

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The patent merges multiple frame bodies into a single integrated frame structure. The first frame body that holds the electro-optical panel is integrated with the second frame body that covers the protrusion surface, eliminating the need for separate assembly of multiple frame components while maintaining heat dissipation functionality through the unified metallic structure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The first frame body serves multiple functions: it holds the electro-optical panel, provides heat dissipation pathways, and integrates with the second frame body to form a complete protective and cooling structure. This multi-functional design eliminates the need for separate dedicated components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Temperature

Solution Approach 1:

By integrating multiple frame bodies into a single molded metallic frame, the patent reduces the number of components that need to be manufactured, stored, and assembled. This consolidation reduces manufacturing complexity and associated costs while maintaining the heat dissipation performance through the integrated metallic structure.

Inventive Principle:

Principle #5Merging (Combining)

3Temperature

If multiple frame bodies are used for holding the electro-optical panel, then heat dissipation is improved, but assembly time increases

Engineering Contradiction:

AI summary

In an electro-optical module, a first transparent plate is provided on a second surface of a first substrate of an electro-optical panel. A size of the first transparent plate is smaller than that of the first substrate, and the first substrate includes a protrusion surface protruding from the first transparent plate. In the frame made of metal that accommodates the electro-optical panel and the first transparent plate therein, corner portions bent along the protrusion surface of the first substrate and the side surfaces of the first transparent plate is provided.
