Wall Display Wire Mounting for Hidden Support and Easy Tilting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted display devices face difficulties in adjusting viewing angles due to cumbersome mechanisms, struggle with supporting large TVs, require additional processing, and expose wires, leading to aesthetic and structural issues.
Innovation Solution
A lifting device with VESA holes, a wire system that includes fixing units with anti-separation portions and buffer members, and rotating arms for easy angle adjustment, securely attaching the display to the wall without additional processing, ensuring the wire is hidden and the device remains parallel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire fixing part is provided at the back cover to fix the wire, then the wire can be secured to the display apparatus, but the wire fixing part may be damaged by the weight of large-size TVs causing release and dropping
Solution Approach 1:
The wire fixing function is separated from the back cover structure. Instead of integrating the wire fixing part into the back cover, the patent uses a separate wire that passes through the back cover and is fixed independently, distributing the load and avoiding concentration of stress on a single integrated component.
Solution Approach 2:
The wire fixing function is extracted from the back cover assembly. The wire is removed as a separate element that can be independently secured, allowing the back cover to focus on its primary structural function while the wire handling is managed by dedicated fixation points.
2Reliability
If a wire fixing part is provided at the back cover to fix the wire, then the wire can be secured to the display apparatus, but additional processing is required increasing manufacturing complexity and costs
Solution Approach 1:
The back cover is designed with multi-functionality, serving both as a structural component and as an integrated wire fixation element. The back cover itself is configured to directly secure the wire without requiring separate dedicated fixing parts, reducing the number of components and manufacturing steps.
3Ease of operation
If the wire is exposed to an area outside of the display apparatus, then the wire can be easily connected, but the outer appearance deteriorates
Solution Approach 1:
The wire is nested within the back cover structure. The wire passes through the back cover and is positioned inside the display apparatus housing, concealing it from external view while maintaining accessibility for connection purposes through strategically placed openings or channels.
4Adaptability or versatility
If pivoting parts are mounted to the back cover for angle adjustment, then the viewing angle can be adjusted, but adjusting the viewing angle becomes difficult and time consuming
Solution Approach 1:
The angle adjustment mechanism incorporates dynamic elements that allow smooth rotation and positioning. The pivoting parts are designed with reduced friction and improved mechanical advantage, enabling the user to easily adjust the viewing angle without excessive force or time.

AI summary
A lifting device used to fix a display apparatus 10 to a wall 32. The display apparatus 10 can be formed in a rear surface thereof with a plurality of holes 12, 13. The lifting device includes a wire 60 having both ends 61 coupled via fixing units 80 to any one pair of holes 12 of the plurality of holes 12, 13, and a wire hanger 70 fixed to the wall 32 and used to hang the wire 60 on the wall 32. The fixing units 80 may each include a buffer member 84 provided at an end portion thereof, such as on the rim, made of rubber or other materials which function to absorb shock to, in use, prevent or substantially reduce damage and/or noise caused upon collision with the wall
