Wall-Mount Display Support With Sliding Links and Stress Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mount-type display device supporting apparatuses are prone to breakage due to stress concentration on hinge shafts and have increased width due to overlapping links, which also increases the distance from the wall to the display device.
Innovation Solution
A supporting apparatus with a fixing unit, height adjustment unit, sliding units, and tilting friction parts that allow for independent movement and adjustment of the display device, distributing stress and maintaining a constant distance through rotatable and sliding mechanisms, and utilizing arc-shaped friction members for enhanced friction and reduced size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If links are used to enable back-and-forth movement of the display device, then movement functionality is improved, but stress concentrates on hinge shafts making the supporting apparatus susceptible to breakage
Solution Approach 1:
The supporting apparatus is divided into multiple independent linkage units, each capable of movement. By segmenting the structure into modular units connected by rotatable joints, the stress that would concentrate on single hinge shafts in a traditional link design is distributed across multiple joints and structural elements, reducing breakage susceptibility while maintaining movement functionality.
2Adaptability or versatility
If links overlap each other to enable movement, then movement capability is improved, but the back-and-forth width of the supporting apparatus increases
Solution Approach 1:
The linkage units are designed with nested structures where components are arranged concentrically or in overlapping configurations that minimize the overall footprint. The rotatable joints and connecting elements are positioned to allow movement while maintaining a compact profile, reducing the back-and-forth width compared to traditional extended link designs.
3Length of stationary object
If the back-and-forth width is reduced by minimizing link overlap, then the distance from wall to display device is reduced, but movement functionality may be compromised
Solution Approach 1:
The supporting apparatus employs dynamic linkage units with rotatable joints that allow the structure to adapt its configuration during movement. The joints can rotate to accommodate back-and-forth motion while the nested design maintains a compact retracted profile, enabling both reduced distance from wall and preserved movement functionality through dynamic reconfiguration.

AI summary
A supporting apparatus of a display device is provided that includes a fixing unit, one or more sliding units, and a device connecting part. The fixing unit may be fixed to a mounting position. The sliding units may be rotatably connected to the fixing unit. The device connecting part may be rotatable relative to the sliding unit and may be coupled with the display device. The sliding unit may include a first sliding member rotatable relative to the fixing unit, and a second sliding member slidable relative to the first sliding member.
