Monitor Support Tension Adjustment for Stable Angle Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supporting structures for flat panel monitors, such as LCD and plasma TVs, cannot effectively adjust tension between flexible bands and shaft wheels, leading to a loss of intended linkage and angle changes during height adjustments.
Innovation Solution
A tension adjusting mechanism is introduced, which includes a retractable connecting unit with a slide engaging sheet and an adjusting member that allows the length of the connecting unit and shaft wheels to be adjusted, maintaining proper tension in the flexible band between the shaft wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flexible band is used to connect the top and bottom shaft wheels, then the linking device can convert circular rotation into rack rotations for compensating displacements, but the tension between the flexible band and shaft wheels is insufficient, generating a lose status and failing to achieve the anticipated linking result
Solution Approach 1:
The patent introduces an adjusting member that modifies the physical parameters of the system by changing the distance between the top and bottom shaft wheels. This parameter change allows the flexible band tension to be adjusted from a fixed insufficient state to an optimized state, directly resolving the contradiction between maintaining linking precision and achieving adequate tension force
Solution Approach 2:
The adjusting member enables the system to self-regulate its tension state. By providing a mechanism that allows users to adjust the shaft wheel distance according to actual needs, the system becomes capable of maintaining optimal tension independently, transforming from a passive insufficient tension state to an actively managed optimal state
2Force
If the distance between top and bottom shaft wheels is increased to maintain tension, then the flexible band tension improves, but the structure becomes more complex and the adjustment mechanism is required
Solution Approach 1:
The adjusting member serves multiple functions simultaneously: it acts as a structural component connecting the shaft wheels, provides the adjustment mechanism for tension control, and functions as a distance regulator. By combining these functions into a single component, the patent avoids increasing overall device complexity while achieving improved flexible band tension
3Reliability
If the connecting unit length is fixed, then the structure is simpler, but the tension of the flexible band cannot be adjusted to maintain proper linking
Solution Approach 1:
The patent transforms the fixed connecting unit structure into a dynamic adjustable structure. The adjusting member enables the distance between shaft wheels to be modified, allowing the system to adapt from a static insufficient tension state to a dynamic optimized tension state, thereby improving linking performance while introducing minimal complexity
