Solution Overview
Problem
Current display devices, such as liquid crystal display panels, face challenges in efficiently integrating a back cover and frame structure that provides structural stability and ease of assembly while minimizing manufacturing costs and thickness.
Innovation Solution
A display device design featuring a back cover with protrusions and connectors that slide into corresponding grooves and connectors on the frame, combined with a guide panel made of resin and glass fiber materials for enhanced rigidity, and an adhesive layer for attaching fixers to the display panel, allowing for a compact and cost-effective assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a back cover and frame structure is integrated into the display device, then structural stability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The back cover is divided into multiple segments with protrusions (first, second, third protrusions) that correspond to separate connectors on the frame. This segmentation allows the back cover to be assembled in modular sections, reducing overall assembly complexity while maintaining structural stability through the distributed connection points.
Solution Approach 2:
The protrusions on the back cover are designed to be inserted into and nested within grooves and connectors on the frame structure. This nesting mechanism enables the back cover to be integrated into the frame through a simple sliding motion, reducing assembly steps and complexity while achieving stable structural integration.
2Ease of operation
If a sliding assembly mechanism with protrusions and connectors is used, then ease of assembly is improved, but manufacturing precision requirements increase
Solution Approach 1:
The groove structures on the frame are designed with sufficient width and tolerance to accommodate minor dimensional variations in the protrusions. This partial excess in the groove dimensions allows for easier assembly with reduced precision requirements, while still providing adequate structural connection when the protrusions are inserted.
Solution Approach 2:
The design employs dimensional parameters with intentional tolerances and variations in the protrusion and groove dimensions. By adjusting these parameters to be less precise than ideal but still functional, the assembly becomes easier while maintaining adequate structural stability, resolving the contradiction between ease of assembly and manufacturing precision.
3Length of stationary object
If the back cover is made thinner to minimize overall thickness, then aesthetic appeal is improved, but structural stability deteriorates
Solution Approach 1:
The back cover is constructed using composite materials that combine lightweight properties with sufficient structural strength. This allows the back cover to maintain thin overall thickness for aesthetic purposes while the composite material structure provides the necessary structural stability and rigidity to support the display device.
Solution Approach 2:
The connectors and protrusions incorporate curved or rounded geometric features that distribute mechanical stresses more effectively throughout the structure. This curvature design allows the back cover to be thinner while maintaining structural integrity, as the curved geometry provides better stress distribution compared to sharp corners or flat surfaces.
