Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing liquid crystal display modules suffer from reduced rigidity due to the elimination of the bottom cover, making them vulnerable to damage from weak impacts, as they strive to achieve a thinner form factor.
Innovation Solution
A liquid crystal display module structure that incorporates a metal cover around the outer sidewall, bottom, and top surfaces of a rectangular frame, integrated using an insert injection molding method with stainless steel, which reinforces the module's rigidity without the need for a conventional bottom cover, while maintaining a thin profile.

Engineering Contradiction Analysis
1Length of moving object
If the bottom cover is eliminated to reduce total thickness, then the liquid crystal display module achieves a thinner form factor, but the rigidity of the module is reduced making it vulnerable to damage
Solution Approach 1:
The invention merges the support main and top cover into a single integrated component. The top cover is formed with an integrated support main that extends downward to provide structural support, eliminating the need for a separate bottom cover while maintaining rigidity. This merging of components achieves both thickness reduction and structural strength.
Solution Approach 2:
The invention extends the top cover structure in the vertical dimension to create the support main. By adding vertical extension to the top cover, the design provides bottom-cover-level support without requiring a separate bottom cover component, thus reducing overall thickness while maintaining rigidity.
2Device complexity
If the bottom cover is eliminated to reduce manufacturing complexity, then the number of components is reduced, but the module becomes weaker and more susceptible to impact damage
Solution Approach 1:
The invention combines the functions of the top cover and support main into a single integrated component. This merging reduces the number of separate parts and assembly steps while maintaining the structural support function that provides impact resistance, thereby improving reliability without increasing complexity.
Solution Approach 2:
The integrated top cover with support main performs multiple functions: it covers the front surface, provides structural support, and enhances impact resistance. This multi-functional design eliminates the need for a separate bottom cover while maintaining protective capabilities.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the rigidity of the liquid crystal display module, protecting it from external impacts and maintaining a slim design, while also reducing manufacturing costs by eliminating the need for a separate bottom cover.
Implementation Method 1
a molding resin is injected to the mold frame of the rectangular frame, and molding is performed so that the rectangular frame and the metal cover are integrally adhered
