Flat panel TV bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat panel TV brackets require labor-consuming and inflexible adjustments for upward/downward angle changes due to torsion springs, and cables can easily fall out of cable clips, affecting normal operation.
Innovation Solution
A flat panel TV bracket with a four-bar linkage mechanism and an air spring for stable and flexible angle adjustment, along with a cable management system using a limiting snap to prevent cable exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If torsion springs are mounted on pins of the hanging plate to prevent downward rotation, then the resistance to downward rotation is increased, but the force required to adjust the angle becomes larger and the operation becomes labor-consuming
Solution Approach 1:
The patent replaces the mechanical torsion spring system with a pneumatic air spring system. The air spring provides the necessary support force to prevent the hanging plate from rotating downward due to gravity, while eliminating the need to overcome high elastic forces during adjustment. The air spring can be easily compressed by hand to adjust the angle, and then maintains the position with minimal holding force.
Solution Approach 2:
The patent introduces an air spring as a pneumatic device to replace the mechanical torsion spring. The air spring uses compressed air to provide the supporting force, allowing for easy adjustment by simply compressing the air spring with hand pressure. The pneumatic system provides smooth, controllable resistance and maintains the hanging plate at various angles without requiring continuous force.
2Ease of manufacture
If an opening is formed at the bottom of a cable clip on a rocker arm, then cables can be packed into the cable clip, but the cable is likely to fall out of the cable clip from the opening
Solution Approach 1:
The patent applies a limiting snap to the cable clip opening before the cable is installed. This preliminary action of adding the limiting snap creates a retention mechanism that prevents the cable from falling out. The limiting snap is pre-installed on the rocker arm, and the cable is then placed through the opening, knowing that it will be retained by the limiting snap.
Solution Approach 2:
The limiting snap acts as an intermediary component between the cable clip opening and the cable. It mediates the interaction by providing a physical barrier that retains the cable while still allowing it to be inserted through the opening. The limiting snap translates the simple opening structure into an effective cable retention system.
