Adjustable Frame-Backplate Assembly for Display Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of display modules in various sizes faces a long development cycle and high mold-making costs due to the need for individualized frames and backplates, lacking a general-purpose solution.
Innovation Solution
A frame-backplate assembly with adjustable side edges and a detachable backplate, utilizing cross-rod linkage mechanisms for scalable connection rods, allowing for easy adjustment and replacement, enabling the use of a general-purpose frame and backplate for different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individualized frames and backplates are designed for each display module size, then the display module can meet specific size requirements, but the development cycle is extended and mold-making costs increase
Solution Approach 1:
The patent applies universality by designing a standardized frame and backplate that can be used across multiple display module sizes. The frame includes adjustable components (first and second adjustable parts) that allow the same frame structure to accommodate different screen dimensions, eliminating the need for size-specific mold-making and reducing development time while maintaining size adaptability
Solution Approach 2:
The frame is segmented into multiple functional parts: a fixed first side edge, an adjustable second side edge with first adjustable part, and a third side edge with second adjustable part. This segmentation allows independent adjustment of specific frame portions to fit different display sizes without redesigning the entire frame structure, thus reducing development cycle while maintaining versatility
2Adaptability or versatility
If individualized frames and backplates are designed for each display module size, then the display module can meet specific size requirements, but mold-making costs increase
Solution Approach 1:
The standardized frame design with adjustable components serves multiple display module sizes, allowing a single mold to produce frames that can be configured for different dimensions. This universality eliminates the need for separate molds for each size variant, significantly reducing mold-making costs while maintaining the ability to meet specific size requirements through adjustment mechanisms
3Adaptability or versatility
If adjustable mechanisms are added to the frame, then the frame can accommodate different display module sizes, but the frame structure becomes more complex
Solution Approach 1:
The frame incorporates dynamic adjustable parts (first and second adjustable parts) that can be configured for different lengths to accommodate various display sizes. These adjustable mechanisms allow the frame to transition between fixed and adjustable states, providing size adaptability while maintaining relatively simple construction through standardized components and connection interfaces
