Display Device Hook Structure for Panel-Safe Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices without a middle frame face challenges in disassembly, leading to potential cracking of the display panel due to increased casing thickness for rigidity, complicating the disassembly process.
Innovation Solution
Incorporating a hook on the main casing behind the frame's side wall, with a position-limiting pillar and block, allowing disassembly without contacting the display panel, and enhancing structural rigidity through mutual limiting mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the thickness of the main casing is increased to have sufficient structural rigidity, then the structural rigidity is improved, but the difficulty of disassembling the display assembly increases and the display panel is likely to crack
Solution Approach 1:
The engagement structure is segmented into multiple components: a hook on the main casing, an engaging portion on the frame, and a position-limiting protrusion on the display assembly. This segmentation allows the disassembly force to be applied to the hook rather than directly to the display panel, enabling easy disassembly while maintaining structural rigidity with a thin casing
Solution Approach 2:
The hook acts as an intermediary element between the main casing and the display assembly. During disassembly, the dismantling tool engages with the hook to apply separation force, preventing direct contact with the display panel and thus avoiding cracks while still allowing effective disassembly
2Ease of operation
If the main casing thickness is reduced to enable easy disassembly, then the ease of operation is improved, but the structural rigidity deteriorates causing the display assembly to separate due to deformation
Solution Approach 1:
The position-limiting protrusion is preliminarily positioned to extend into the main casing along the front-rear direction, and the hook is preliminarily positioned behind the side wall to engage with the frame. These preliminary positioning arrangements ensure that during disassembly, the display assembly remains stable and does not separate due to casing deformation, even when the casing thickness is reduced
Solution Approach 2:
The hook is locally positioned behind the side wall of the frame rather than directly adjacent to the display panel. This local quality differentiation allows the main casing to have sufficient rigidity at critical engagement points while maintaining overall thinness, preventing display assembly separation during disassembly

AI summary
A display device, including a main casing and a display assembly, is provided. The main casing has a hook, a position-limiting pillar, and a position-limiting block. The position-limiting block is adjacent to the position-limiting pillar. The display assembly includes a frame and a display panel. The frame has a side wall, and the hook is located behind the side wall in a front-rear direction of the display device and is engaged with the frame. The position-limiting pillar penetrates the display assembly along the front-rear direction, and the position-limiting block leans against the display assembly along the front-rear direction. The display panel is disposed in the frame, and the side wall surrounds a periphery of the display panel.
