Screen Stand Damping Gear for Stable Height and Push Force
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 incorporating a damping gear that adjusts damping force to balance weight and compensate for worn-out friction, using an elastic component and a damping gear with an adjusting portion to maintain consistent 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 and versatility of the electronic equipment is improved, but the weight balance is disrupted causing the screen to slide down or require inconsistent push force
Solution Approach 1:
The patent introduces a damping gear with an adjusting portion that allows the damping force to be dynamically adjusted. This enables the stand to adapt to different weight conditions when additional assemblies are installed, maintaining proper balance and consistent push force by modifying the damping characteristics in response to changing load conditions.
Solution Approach 2:
The adjusting portion of the damping gear enables change in the damping force parameter. By adjusting this parameter, the stand can compensate for the additional weight from installed assemblies, restoring the equilibrium between the spring force and the total weight, thereby preventing the screen from sliding down and ensuring consistent push force.
2Measurement precision
If a friction block is used to maintain screen position, then positioning accuracy is improved, but the friction block wears out over time losing its positioning capability
Solution Approach 1:
The damping gear acts as an intermediary mechanism between the support component and the base. Instead of relying solely on the friction block for positioning, the damping gear provides a controllable damping force that assists in maintaining screen position, reducing the wear burden on the friction block and extending its service life while maintaining positioning accuracy.
Solution Approach 2:
The damping gear provides prior cushioning by absorbing and dampening forces before they reach the friction block. This protective effect reduces the impact and wear on the friction block, preserving its positioning capability for longer periods and maintaining reliable friction positioning over time.
3Force
If the spring force is increased to support additional weight, then the weight bearing capacity is improved, but the push force required to move the screen becomes inconsistent and the screen may slide down
Solution Approach 1:
The damping gear with adjusting portion provides a dynamic solution where the damping force can be modified to match the actual load conditions. This allows the system to maintain proper force balance without excessively increasing the spring force, ensuring consistent push force characteristics and preventing the screen from sliding down under various load conditions.
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 push force required to move the electronic device up and down, even with additional assemblies and worn-out friction components, ensuring precise positioning.
Implementation Method 1
The elastic component is connected between the base and the support component. The support component resists a weight from the electronic device at least by an elastic force of the elastic component
Implementation Method 2
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
