Spliced Display Unit Detachment via Controlled Gap Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in replacing a defective display unit in a spliced display device is the potential damage to adjacent units due to the need to detach from the edge, leading to inefficient and potentially damaging detachment processes.
Innovation Solution
A detachment device with a detachment mechanism and moving devices that allow controlled separation of display units by adjusting the splicing gap, using mechanisms like moving frames, adjustment members, and guide rails to manage the detachment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If detaching from the edge of the spliced display device, then the defective display unit can be removed, but the operation time increases and the risk of damaging adjacent display units increases
Solution Approach 1:
The patent introduces a detachment device as an intermediary tool between the defective display unit and adjacent units. This device includes a moving frame with moving devices that can precisely control the detachment process, allowing the defective unit to be separated without direct contact that could damage adjacent units, while significantly reducing the time required compared to manual edge-detachment methods.
2Reliability
If using traditional detachment methods, then the defective display unit can be removed, but adjacent display units may be damaged due to rubbing or contact
Solution Approach 1:
The detachment device serves as a mediator that prevents direct contact between the defective display unit and adjacent units during detachment. The moving frame structure with controlled moving devices ensures that the defective unit is separated without rubbing or contact that could cause damage, while the structured design keeps the operational complexity manageable through standardized components.
Solution Approach 2:
The detachment device is segmented into multiple independent moving devices (first moving device, second moving device, etc.) that can operate independently on different sides of the defective display unit. This segmentation allows precise control over the detachment process from multiple directions simultaneously, protecting adjacent units while maintaining manageable complexity through modular design.
3Ease of repair
If detaching multiple display units through extensive detachment processes, then defective units can be replaced, but the risk of new defective operations increases
Solution Approach 1:
The detachment device acts as a protective intermediary during the replacement process, ensuring that adjacent display units are not damaged during detachment operations. The controlled moving mechanisms prevent accidental contact or rubbing that could create new defects, thereby maintaining high reliability while enabling easy replacement of defective units.
Solution Approach 2:
The detachment device performs preliminary positioning and control actions before the actual detachment occurs. The moving devices are pre-positioned and the detachment process is pre-planned with controlled movement paths, ensuring that no new defective operations occur during the replacement process while maintaining ease of repair.

AI summary
An detachment device for a spliced display device includes: a detachment mechanism disposed to be connected with the first display unit to drive the first display unit to move along a direction away from or close to a plane where the spliced display device is located; at least one moving device, wherein the moving device includes a moving frame located outside the detachment mechanism and an adjustment member disposed on the moving frame, the moving frame is connected with the second display unit, the adjustment member abuts against the detachment mechanism, and the moving frame drives the second display unit connected with the moving frame to move in a direction away from the first display unit through the adjustment member on the plane where the spliced display device is located.
