Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies such as liquid crystal panels suffer from slow response times, high power consumption, and screen burn-in issues, while OLED panels are susceptible to screen burn-in and require backlights, limiting their compactness and efficiency.
Innovation Solution
A display apparatus utilizing micro-LED panels with inorganic light emitting devices mounted on a substrate, supported by a frame with a specific coupling mechanism and reinforcing members, allowing for detachable attachment of display modules in an M*N matrix configuration, enhancing torque resistance and flat surface tiling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional frame structure is used to support display modules, then the device complexity is low, but the pulling force and torque resistance are insufficient
Solution Approach 1:
The frame is divided into a panel frame and a rear frame that are detachably coupled through coupling portions. This segmentation allows each frame component to be optimized independently for strength while maintaining overall structural integrity, resolving the contradiction between strength and complexity.
Solution Approach 2:
The coupling portions are inserted into coupling holes, creating a nested structure where the panel frame and rear frame interlock. This nesting provides mechanical interlocking that enhances pulling force and torque resistance without requiring complex additional components.
2Strength
If the frame structure is made more robust to improve torque resistance, then the strength increases, but the weight increases
Solution Approach 1:
The frame uses detachable coupling portions that allow for dynamic assembly and disassembly. This dynamic design enables the use of thinner, lighter frame components that can be joined to achieve the required torque resistance, rather than using a single heavy rigid structure.
Solution Approach 2:
The frame components utilize composite construction with coupling portions made of materials optimized for mechanical interlocking. This allows the frame to achieve high torque resistance through the combination of multiple lightweight components rather than a single heavy material.
3Shape
If display modules are attached directly to the frame, then the device complexity is low, but the surface flatness is insufficient
Solution Approach 1:
The coupling portions are pre-formed on the frame components during manufacturing. This preliminary action ensures that the coupling structures are already in place to provide the necessary surface flatness when display modules are attached, eliminating the need for additional flatness-correcting components.
Solution Approach 2:
The coupling portions serve multiple functions: they provide mechanical attachment for display modules while simultaneously ensuring surface flatness. This multi-functionality resolves the contradiction by achieving both attachment and flatness without adding separate components.
