Stackable TV Wall Mount Arms for Wide-Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall mounts for display devices, such as televisions, lack the ability to adjust to a wide range of angles, particularly in limited spaces, making it difficult to achieve multi-angle functionality and efficient installation.
Innovation Solution
A wall mount design featuring a metal wall fixing member, a rotatable supporting member with a telescopic structure comprising rear, middle, and front arms, and an adjustable back plate, allowing for multi-angle adjustment by changing the stacked arrangement of the arms, which improves stability and flexibility in mounting on various wall sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional fixed wall mount is used, then the installation is simple, but the multi-angle adjustment capability is poor
Solution Approach 1:
The supporting member is divided into multiple arms (first arm, second arm, third arm, fourth arm) that can be independently positioned and fixed. Each arm can be adjusted to different angles and positions, allowing the display device to be mounted at various orientations while maintaining structural integrity through modular segmentation.
Solution Approach 2:
The wall mount transitions from a fixed rigid structure to a dynamic adjustable structure. The arms can be rotated and repositioned relative to each other, enabling the mount to adapt to different viewing angles and wall configurations. The fixing members allow the structure to be locked at desired positions, providing both adjustability and stability.
2Adaptability or versatility
If the wall mount structure is extended to achieve wider angle adjustment, then the multi-angle functionality is improved, but the material usage increases
Solution Approach 1:
The arms are designed to be stackable and nestable within each other when not in use. The first arm can accommodate the second arm, and the third arm can accommodate the fourth arm, creating a compact folded configuration. This nesting design allows for extended angle adjustment capability when deployed, while minimizing material footprint and space occupation when stored or in non-use positions.
3Adaptability or versatility
If the arm length is increased to expand adjustment range, then the multi-angle capability is improved, but the stability decreases
Solution Approach 1:
Instead of using a single long arm that would be unstable, the structure is segmented into multiple shorter arms connected through fixing members. Each arm maintains a reasonable length-to-strength ratio, while the segmented configuration with multiple connection points distributes mechanical loads more effectively, enhancing overall stability despite the extended adjustment range.
Solution Approach 2:
The fixing members are designed to secure each arm at predetermined positions before final assembly. This preliminary positioning ensures that each arm is properly aligned and locked in its intended configuration, preventing instability during operation. The pre-designed connection points guide the assembly process to ensure optimal structural stability.
