Display Screen Bracket Cam-Roller Structure for Smooth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display screen brackets suffer from insufficient smoothness in adjustment due to instability in the force applying mechanism, curved surface of the cam member, and roller interaction, leading to uncoordinated and difficult adjustments.
Innovation Solution
A smoothly adjustable display screen bracket design incorporating a force applying mechanism with a pressure spring, limiting sleeve, and cam member, where the pressure spring is abutted by the cam member and the limiting sleeve covers the spring to prevent swinging, ensuring stable and smooth adjustments through a connecting rod group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the force applying mechanism, curved surface of cam member and roller are used for adjustment, then stepless adjustment is achieved, but the adjustment is not smooth enough due to insufficient coordination and spring swaying
Solution Approach 1:
The cam member employs a curved surface that works in coordination with the roller to enable smooth stepless adjustment. The curved profile of the cam member transforms rotational motion into linear displacement, providing continuous position adjustment while maintaining stable coordination between components.
Solution Approach 2:
The roller acts as an intermediary element between the cam member and the connecting rod group. It facilitates smooth force transmission and reduces friction, ensuring coordinated movement and preventing instability during adjustment operations.
2Force
If the pressure spring is used in the force applying mechanism, then the cam member can press against the roller, but the spring sways during adjustment causing instability
Solution Approach 1:
The limiting sleeve acts as a flexible constraint structure that envelops the pressure spring. It provides lateral support to the spring during compression and extension, preventing swaying and instability while allowing the spring to perform its force-applying function effectively.
3Strength
If the connecting rod group is used to connect the first and second connecting seats, then the display screen can be supported, but the connecting rod group is unstable and difficult to move during adjustment
Solution Approach 1:
The roller serves as a mediating element between the cam member and connecting rod group, facilitating smooth force transmission during adjustment. This intermediary component reduces friction and enables the connecting rod group to move easily while maintaining its load-bearing capacity.
Solution Approach 2:
The curved surface of the cam member works with the roller to provide continuous, smooth adjustment of the connecting rod group position. This curved mechanism enables the strong connecting rod group to be adjusted easily through rotational motion of the cam member.
