Display Support Spring Balancing With Threaded Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mechanical spring display supports experience poor height adjustment due to reliance on friction, resulting in a worse experience compared to air spring supports, which have high costs, short lifespans, and environmental concerns.
Innovation Solution
A display support with a mechanical spring and threaded sliding block mechanism, where the mechanical spring is hinged with the connector and threaded sliding block, allowing for adjustable height by rotating a threaded rod, ensuring gravitational torque equals elastic torque for balanced weight and height adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical spring structure is used for height adjustment, then cost is reduced and lifespan is extended, but height adjustment experience deteriorates due to reliance on friction
Solution Approach 1:
The patent replaces the traditional friction-based mechanical spring adjustment mechanism with a threaded rod and sliding block mechanism. This substitution transforms the reliance on friction into a precision threaded connection system, where rotational motion of the threaded rod converts to linear motion of the sliding block, enabling smooth and precise height adjustment without depending on friction forces.
Solution Approach 2:
The patent changes the adjustment parameter from friction-dependent force to threaded rotational displacement. By using the threaded rod's pitch and rotation angle as the control parameter, the system achieves precise and repeatable height adjustment positions, improving the ease of operation while maintaining the mechanical spring's reliability advantages.
2Object-affected harmful factors
If a mechanical spring structure is used for height adjustment, then environmental protection and safety are improved, but height adjustment experience deteriorates due to reliance on friction
Solution Approach 1:
The patent replaces the friction-based mechanical spring adjustment mechanism with a threaded rod and sliding block mechanism. This substitution transforms the reliance on friction into a precision threaded connection system, where rotational motion of the threaded rod converts to linear motion of the sliding block, enabling smooth and precise height adjustment without depending on friction forces.
3Ease of operation
If air spring structure is used for height adjustment, then height adjustment experience is improved with stable air spring force, but cost increases and lifespan decreases
Solution Approach 1:
The patent extracts the height adjustment function from the air spring system and implements it separately using a threaded rod and sliding block mechanism. This allows the mechanical spring to retain its load-bearing function while the threaded mechanism provides precise position control, combining the advantages of both systems without the air spring's reliability issues.
4Ease of operation
If air spring structure is used for height adjustment, then height adjustment experience is improved with stable air spring force, but environmental protection deteriorates due to disposal difficulty
Solution Approach 1:
The patent extracts the height adjustment function from the air spring system and implements it separately using a threaded rod and sliding block mechanism. This allows the mechanical spring to retain its load-bearing function while the threaded mechanism provides precise position control, combining the advantages of both systems without the air spring's reliability issues.

AI summary
A display support having a freely adjustable height, including a base and a connector for installing a display, wherein an upper connecting arm and a lower connecting arm, which are parallel to each other, are arranged between the base and the connector. The display support further includes a mechanical spring, wherein an end of the mechanical spring is hinged with the connector or the lower connecting arm, the other end of the mechanical spring is hinged with a threaded sliding block, the threaded sliding block sleeves on a threaded rod, the threaded rod is arranged in the base, so that when an end part of the threaded rod is operated to drive the threaded rod to rotate, the threaded sliding block moves along the threaded rod, and a position of the threaded sliding block on the threaded rod is adjusted according to the weight of the display on the connector, so that when the connector is moved upwards or downwards, the connector is stopped at different heights relative to the base. The display support having the freely adjustable height can realize free stop of height adjustment, and thus is better than an air spring support.
