Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal module structures are complex and costly, with limited space for the backlight module due to internal positioning elements and frames, making assembly difficult and expensive.
Innovation Solution
A liquid crystal module structure featuring a back plate with a cavity and an elastic rubber frame that connects and secures the liquid crystal panel and backlight module, eliminating the need for complex frames and fastening elements by using an adhesive or double tape for assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If positioning elements and supporting elements are added to fix the liquid crystal panel, then the panel can be fixed securely, but the structure becomes complicated and costs increase
Solution Approach 1:
The patent combines the positioning function and supporting function into a single integrated frame structure. The frame serves both to position the liquid crystal panel and to support it, eliminating the need for separate positioning elements and supporting elements. This merging of functions reduces structural complexity while maintaining fixing reliability.
Solution Approach 2:
The frame is designed to perform multiple functions simultaneously: it provides structural support, positions the liquid crystal panel, and secures the backlight module. This multi-functional design eliminates the need for dedicated positioning elements and supporting elements, simplifying the overall structure while ensuring reliable fixation.
2Reliability
If positioning elements and supporting elements are added to fix the liquid crystal panel, then the panel can be fixed securely, but manufacturing costs increase
Solution Approach 1:
By merging the positioning and supporting functions into a single frame structure, the patent reduces the total number of components that need to be manufactured and assembled. This consolidation lowers manufacturing costs while maintaining secure fixation of the liquid crystal panel.
Solution Approach 2:
The patent extracts and eliminates unnecessary positioning elements and supporting elements from the traditional multi-component design. By removing these redundant components and integrating their functions into the frame, the manufacturing process is simplified and costs are reduced.
3Ease of operation
If front frame and plastic frame with moldings and fastening elements are used, then assembly is assisted, but the process becomes troublesome and costs increase
Solution Approach 1:
The patent merges the functions of the front frame and plastic frame into a single integrated frame structure. This eliminates the need for multiple separate frames and their associated moldings and fastening elements, simplifying the assembly process while maintaining ease of operation.
Solution Approach 2:
The patent replaces the mechanical fastening system (screws, clips, and other fastening elements) with an integrated frame structure that provides both support and fixation through its design. This substitution eliminates the need for separate fastening operations, simplifying assembly while maintaining ease of operation.
4Ease of operation
If multiple frames and fastening elements are used, then assembly is assisted, but manufacturing costs increase
Solution Approach 1:
By combining multiple frames and fastening elements into a single integrated frame structure, the patent reduces the total number of components that need to be manufactured and assembled. This consolidation lowers manufacturing costs while maintaining ease of assembly through the integrated design.
