Solution Overview

Problem

Liquid crystal displays face structural vulnerabilities when parts are mounted, leading to reduced impact resistance and potential damage to the mold frame, liquid crystal display panel, or circuit components.

Innovation Solution

A reinforced mold frame with a part mounting unit and a chassis featuring a reinforcing tab that contacts the part mounting unit to enhance strength, including a mounting surface with notches and openings, and linking parts to improve structural integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a portion of the mold frame is removed to establish a part mounting area, then parts can be mounted on the module, but the mold frame becomes less resistant to impact and may be damaged

Engineering Contradiction:

Improvepart mounting capabilityVSAvoidimpact resistance of mold frame

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The mold frame is segmented into multiple regions: intact sidewalls that maintain structural strength and a part mounting unit with openings that provides mounting capability. This segmentation allows different portions of the mold frame to serve different functions - the sidewalls provide structural support while the mounting unit allows part installation

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mold frame exhibits local quality variations where different regions have different properties. The sidewalls maintain full structural integrity for impact resistance, while the part mounting unit has localized openings that reduce strength only where necessary for mounting parts. The reinforcing tab is strategically placed to provide local reinforcement without compromising the mounting functionality

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If a portion of the mold frame is removed to establish a part mounting area, then parts can be mounted on the module, but the liquid crystal display panel or circuit components may be damaged

Engineering Contradiction:

Improvepart mounting capabilityVSAvoidprotection of display panel and circuit components

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The reinforcing tab is installed beforehand in the part mounting unit to provide structural reinforcement before parts are mounted. This pre-reinforcement ensures that the mold frame can withstand impact forces and protect the display panel and circuit components from damage, even in the weakened mounting region

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
