Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electro-optical devices face challenges in minimizing size and thickness due to the separate components of resin and metal casing frames, which increase the number of components and make it difficult to prevent damage from static electricity.
Innovation Solution
An electro-optical device with a frame that integrates a metal plate and resin part, where the metal plate is insert-molded into the resin, forming a conduction path that protrudes to facilitate static electricity discharge without additional components, thereby reducing the device's size and thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a casing frame made of resin and a member made of metal are provided separately and fixed by screws, then static electricity can be transmitted through the screws as earth paths, but the number of components increases and it becomes difficult to miniaturize and decrease the thickness of the electro-optical device
Solution Approach 1:
The patent combines the resin casing frame and metal member into a single integrated frame structure where the metal conduction part is embedded within the resin part. This merging eliminates the need for separate components and fastening elements like screws, thereby reducing component count while maintaining static electricity discharge functionality through the integrated conduction path.
Solution Approach 2:
The patent creates a composite frame structure consisting of a resin part containing an embedded metal conduction part. This composite structure integrates the insulating properties of resin with the conductive properties of metal, enabling both mechanical support and static electricity protection functions within a single unified component that reduces overall device complexity.
2Reliability
If a casing frame made of resin and a member made of metal are provided separately and fixed by screws, then static electricity can be transmitted through the screws as earth paths, but the electro-optical device size and thickness increase
Solution Approach 1:
The patent merges the resin casing frame and metal member into a single integrated frame structure, eliminating the need for separate fastening elements like screws that would increase device thickness. The metal conduction part is embedded within the resin part, creating a unified structure that maintains static electricity discharge functionality while minimizing overall device dimensions.
Solution Approach 2:
The patent implements a nested structure where the metal conduction part is embedded or inserted within the resin part. This nesting approach allows the conductive element to be housed within the insulating material, eliminating the need for additional external components and reducing the overall thickness of the frame structure while maintaining both protective and conductive functions.
3Reliability
If the electro-optical device is configured by combining many components, then static electricity protection can be achieved, but it becomes difficult to miniaturize the electro-optical device
Solution Approach 1:
The patent combines multiple functional components (resin casing frame, metal member, and fastening elements) into a single integrated frame structure. The metal conduction part is embedded within the resin part, creating a unified component that provides both structural support and static electricity protection, thereby eliminating the volume occupied by separate components and enabling device miniaturization.
Solution Approach 2:
The integrated frame structure serves multiple functions simultaneously: the resin part provides mechanical support and insulation, while the embedded metal conduction part provides static electricity discharge pathways. This multi-functional design eliminates the need for separate dedicated components for each function, reducing overall device volume while maintaining comprehensive protection capabilities.

AI summary
An electro-optical device includes a frame including a conduction part and a resin part, an electro-optical panel that is housed in the inner side of the resin part, and an exposure part that is formed by exposing the conduction part from the resin part. The exposure part is disposed to face at least a part of an end face of the electro-optical panel or protrude from a surface of the electro-optical panel over the end face.
