Display Stand Brake Mechanism for Ergonomic Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height adjustable stands for electronic displays face challenges with counterbalancing mechanisms, which are either difficult to use for light displays due to friction issues or ineffective in maintaining position, and require users to reach behind the screen to adjust height, leading to ergonomic positioning difficulties.
Innovation Solution
A stand with a brake mechanism that can be unlocked and adjusted by an actuator located at the outer edge of the display, allowing for ergonomic positioning without counterbalancing forces, enabling easy height adjustment by grasping the display naturally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If counterbalancing mechanisms are used for light displays, then height adjustment is easier, but the display position cannot be maintained due to friction issues
Solution Approach 1:
The patent extracts the counterbalancing mechanism from the system entirely, replacing it with a brake mechanism that uses friction to hold the display at any position. This eliminates the friction-related position maintenance problems of counterbalancing mechanisms while keeping height adjustment easy through the actuator.
Solution Approach 2:
The brake mechanism acts as an intermediary between the display weight and the support structure. Instead of using counterbalancing forces that create friction problems, the brake mechanism provides controlled friction through the brake pad and rotor interface to maintain position reliably.
2Ease of operation
If counterbalancing mechanisms are used for extremely light displays, then height adjustment is possible, but the stand lifts off the support surface instead of acting against the mechanism
Solution Approach 1:
The patent removes the counterbalancing mechanism that causes the stand to lift off the support surface. The brake mechanism is designed to work with the stand's weight, providing stable operation without causing the entire stand to lift during adjustment.
Solution Approach 2:
The brake mechanism applies preliminary friction force to prevent the stand from lifting during height adjustment. The brake pad maintains contact with the rotor, creating a stabilizing force that counteracts any lifting tendency before it can occur.
3Strength
If clamps are positioned behind the display for height adjustment, then structural support is improved, but user accessibility deteriorates
Solution Approach 1:
The actuator is extended along the longitudinal axis of the stand, moving the control interface from the rear (inaccessible position) to the front/side (accessible position). This dimensional repositioning allows users to operate the actuator while grasping the display, eliminating the accessibility problem while maintaining structural support.
Solution Approach 2:
The actuator serves as an intermediary that transmits the user's grasping force to the brake mechanism. By positioning the actuator where users can naturally grasp it, it mediates between user interaction and the internal brake mechanism, improving accessibility without compromising structural integrity.

Function Achieved in This Case
The solution provides easy and ergonomic height adjustment for light electronic displays, eliminating the drawbacks of counterbalanced stands while maintaining the convenience of counterbalanced systems, ensuring the display remains securely positioned without creeping or lifting off the surface.
Implementation Method 1
the weight of the display can be about the same as the amount of friction inherent in a counterbalancing mechanism
