Display Module Spacing Adjustment via Wedge Spacer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in adjusting the spacing between adjacent display modules without causing them to excessively move, making it difficult to maintain proper alignment and visibility of the image displayed on the screen.
Innovation Solution
The implementation of X-spacing and Y-spacing adjusters, which include screws and through-holes with specific diameters and configurations, allows for precise adjustment of the spacing between display modules by rotating the screws to increase or decrease the gap, facilitating alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display modules are shifted to adjust spacing, then the spacing between modules can be changed, but the modules gain momentum and excessively move, making fine adjustment difficult and time-consuming
Solution Approach 1:
A wedge-shaped spacer is introduced as an intermediary component between adjacent display modules. The spacer includes a wedge portion that fits into a groove on the display module, allowing spacing adjustment through lateral movement rather than direct shifting of the heavy display modules. This mediator enables precise spacing control without causing excessive movement or momentum issues.
Solution Approach 2:
The wedge portion of the spacer is designed to be movable laterally within the groove, enabling dynamic adjustment of the spacing between display modules. By moving the wedge portion laterally, the spacing can be precisely controlled without requiring direct manipulation of the entire display module, thus avoiding momentum-related adjustment difficulties.
2Adaptability or versatility
If display modules are connected together, then a single display screen is formed, but the boundaries between modules become conspicuous when spacing deviates from design value
Solution Approach 1:
The wedge-shaped spacer acts as a mediator that maintains precise spacing between adjacent display modules. By controlling the position of the wedge portion within the groove, uniform spacing is achieved across all modules, ensuring that boundaries remain inconspicuous while forming a complete display screen.
Solution Approach 2:
The spacer provides localized spacing control at each interface between adjacent display modules. By independently adjusting the wedge portion position at each location, precise spacing uniformity is achieved across the entire display screen, preventing conspicuous boundaries while maintaining overall screen integrity.
3Strength
If screws are used to connect display modules, then the modules can be firmly attached, but the structure becomes complex and difficult to adjust
Solution Approach 1:
The complex multi-screw connection structure is extracted and replaced with a simplified wedge-and-groove mechanism. The wedge portion fits into the groove and provides firm attachment through lateral positioning, eliminating the need for multiple screws while maintaining connection strength and enabling easy spacing adjustment.
Solution Approach 2:
The traditional screw-based mechanical connection system is replaced with a wedge-based mechanical system. The wedge portion utilizes lateral movement within the groove to achieve both firm attachment and adjustable spacing, simplifying the connection structure while maintaining or improving functional performance.

AI summary
At least one first display module selected from display modules arranged in a matrix to form a display screen for displaying an image has a first screw hole into which a first screw is screwed with the first screw pressed against a second display module placed adjacent to the first display module in forming the display screen. The first display module has a through-hole. The second display module has a second screw hole into which a second screw is screwed after the second screw is put through the through-hole toward the second display module. The second screw includes a shank having an outer diameter smaller than an inner diameter of the through-hole and a head having an outer diameter greater than the inner diameter of the through-hole.
