Adjustable Damping Stand for Stable Screen Height Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stands for elevating screens face issues with weight imbalance and inconsistent push force due to additional assemblies, and friction blocks wear out over time, leading to inaccurate height maintenance.
Innovation Solution
A stand equipped with a damping gear that adjusts damping force and compensates for friction loss, maintaining balance by integrating an elastic component, damping gear, and optionally a friction component to stabilize the electronic device's height and push force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional assemblies (light shield, light stand, video device) are installed on the screen, then the functionality of the electronic equipment is enhanced, but the weight balance between the screen and spring force becomes unbalanced, causing the screen to slide down or require inconsistent push force
Solution Approach 1:
The patent introduces an adjustable damping mechanism that can dynamically modify the damping force to adapt to different weight conditions. The damping coefficient adjustment capability allows the system to maintain stable positioning performance even when additional assemblies are installed on the screen, resolving the weight balance issue while preserving functionality.
2Measurement precision
If a friction block is used to maintain the position of the screen, then the positioning accuracy is improved, but the friction block wears out after long-term use and cannot properly exert the friction positioning effect
Solution Approach 1:
The patent replaces the traditional friction-based positioning mechanism with a damping-based positioning system. The damping mechanism uses viscous damping force instead of dry friction, which does not suffer from wear problems. This substitution maintains positioning accuracy while significantly improving long-term reliability and consistency of the positioning effect.
3Stability of the object's composition
If the damping force is increased to compensate for additional weight, then the weight balance is restored, but the push force required to move the screen becomes inconsistent and harder to operate
Solution Approach 1:
The adjustable damping mechanism allows the damping coefficient to be optimized for different operating conditions. By properly tuning the damping force, the system achieves both stable positioning (weight balance) and smooth operation (consistent push force). The adjustment capability ensures that the damping force compensates for additional weight without creating excessive resistance during screen movement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The stand accurately maintains the height and consistent push force required to move the electronic device up and down, even with additional assemblies and despite friction block wear, ensuring precise positioning.
Implementation Method 1
The support component resists a weight from the electronic device at least by an elastic force of the elastic component
Implementation Method 2
The support component resists a weight from the electronic device at least by an elastic force of the elastic component and a damping force of the damping gear
Implementation Method 3
The stand further resists the weight from the electronic device by a friction force between the friction component and the base to be positioned at the predetermined position

AI summary
A stand includes a base, a support component, an elastic component and a damping gear. The support component is slidably disposed on the base and adapted to support an electronic device and slide to a predetermined position relative to the base. The elastic component is connected between the base and the support component. The damping gear is rotatably disposed on the base and adapted to be coupled to the support component. The support component resists a weight from the electronic device at least by an elastic force of the elastic component and a damping force of the damping gear to be positioned at the predetermined position. The damping gear has an adjusting portion and is adapted to adjust the damping force through the adjusting portion. In addition, an electronic equipment includes the stand.
