Solution Overview
Problem
The existing display devices face issues with relative deflection between laminated panels during assembly, leading to a small force-bearing area and impact resistance, causing adhesion deterioration and displacement during transport, which affects the display effect.
Innovation Solution
A plastic frame with a limiting part and a supporting part, featuring a fixing unit with triangular wedge blocks that contact the side surfaces of both panels, providing increased stability and resistance to displacement, and a skid-resistant layer with zigzag protrusions to prevent sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display screen is fixed by a limiting part of a plastic frame with line-contact lamination, then the structure is simple, but the force bearing area is small and impact resistance is poor
Solution Approach 1:
The fixing structure is segmented into multiple wedge blocks (first wedge block and second wedge block) that are distributed along the side surfaces of the panels. This segmentation increases the number of contact points and distributes the impact force across multiple locations, thereby improving impact resistance while maintaining structural simplicity
Solution Approach 2:
The fixing unit extends from a single line-contact dimension to a multi-point contact dimension by introducing wedge blocks that contact the side surfaces of both panels at different positions. This dimensional expansion increases the force bearing area and improves impact resistance without significantly increasing structural complexity
2Ease of manufacture
If the display screen is fixed by a limiting part of a plastic frame with line-contact lamination, then the assembly is simple, but the lamination effect deteriorates under impact
Solution Approach 1:
The wedge blocks are pre-installed on the limiting part before the panels are positioned. This preliminary action ensures that the panels are immediately supported at multiple points upon insertion, preventing relative deflection and protecting the lamination effect from deterioration during assembly
Solution Approach 2:
The wedge blocks act as intermediary elements between the limiting part and the panels. They mediate the force transmission and provide distributed support that protects the adhesive lamination from concentrated stresses, thereby improving reliability while maintaining assembly simplicity
3Ease of operation
If there is a gap between the display screen and the limiting part, then the assembly is easy, but the panels are easily displaced during transport
Solution Approach 1:
The wedge blocks are designed to be self-adjusting within the gap between the limiting part and the panels. During assembly, the panels naturally push the wedge blocks into their fixed positions, achieving stable fixation without requiring precise gap control or complex adjustment mechanisms, thereby maintaining ease of assembly while improving stability
Solution Approach 2:
The wedge blocks transform the loose gap parameter into a tight fixation state through their wedge geometry. When inserted into the gap, the wedge shape converts the initial loose fit into a secure, displacement-resistant connection, improving panel stability during transport while preserving assembly ease
