Tilt Ring Friction Mechanism for High-Load Display Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard display support systems are inadequate for larger displays, as they lack the necessary retention force to maintain the desired position, leading to instability and limited flexibility in positioning.
Innovation Solution
A support system with a tilt mechanism featuring a diamond-shaped tilt ring and adjustment mechanism, including a rotating member and transverse pin, which modifies the frictional engagement between the tilt ring and ring housing to securely hold displays of varying sizes, allowing for adjustable positioning without requiring user adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a standard display head is used to support a larger display, then the display can be mounted, but the retention force is insufficient to maintain the desired position
Solution Approach 1:
The frictional engagement between the tilt ring and ring housing is modified by changing the normal force parameter. The adjustment mechanism applies an additional force to press the tilt ring against the ring housing, increasing the frictional force according to the friction law (F_friction = μ * F_normal). This allows the system to maintain positional stability for heavier displays by dynamically adjusting the retention force parameter.
2Reliability
If the frictional engagement between the tilt ring and ring housing is increased to improve retention, then the display position is more stable, but the ease of adjustment decreases
Solution Approach 1:
The system transitions from a static frictional engagement to a dynamic one. The adjustment mechanism allows the normal force between the tilt ring and ring housing to be dynamically adjusted. During positioning, the user can apply force to overcome the friction, and once positioned, the mechanism maintains optimal frictional engagement for stability. This dynamic adjustment resolves the contradiction between ease of operation and position stability.
3Adaptability or versatility
If a moveable support arm is used to provide positioning flexibility, then the display can be positioned at various locations, but the retention force is insufficient for larger displays
Solution Approach 1:
The support system is segmented into distinct functional components: the moveable support arm provides positioning flexibility, while the separately adjustable tilt mechanism with modified frictional engagement provides retention force. This segmentation allows each component to optimize its specific function without compromising the other, enabling the system to handle larger displays while maintaining positioning flexibility.
