Supporting Stand Tension Compensation With Gear-Assisted Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supporting stands require repetitive and labor-intensive adjustments to achieve desired tension forces due to direct connection of knurled screw nuts to screw rods, limiting quick adjustments of compensation force.
Innovation Solution
A supporting stand design featuring a bearing unit, first and second rods, a sleeve assembly, a regulating assembly with a gear structure, and elastic elements, allowing for easy adjustment of tension force by rotating the second sleeve to drive the gear and screw, thereby lengthening or shortening the elastic elements and cables, facilitating quick changes in compensation force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the knurled screw nut is directly connected to the screw rod through internal thread, then the structure is simple, but the adjustment of tension force requires repetitive rotations and takes time and labor
Solution Approach 1:
The patent introduces a gear mechanism as an intermediary between the knurled screw nut and the screw rod. The gear with multiple teeth allows the knurled screw nut to drive the screw rod more efficiently, reducing the number of rotations needed to achieve the same tension adjustment. This intermediary mechanism transforms the direct thread connection into a gear-assisted connection, making adjustment faster and less labor-intensive.
2Productivity
If the knurled screw nut rotates 360 degrees to raise or descend the screw rod by one pitch, then the thread connection is straightforward, but multiple rotations are needed to achieve greater tension adjustment
Solution Approach 1:
The gear mechanism is pre-configured with multiple teeth engaged with the screw rod threads. This preliminary arrangement allows a single rotation of the knurled screw nut (through the gear) to produce a larger effective movement of the screw rod compared to direct thread engagement. The gear's tooth configuration is designed in advance to multiply the rotational effect, enabling faster tension adjustment without requiring multiple separate rotations.

AI summary
A supporting stand comprises a bearing unit, a first rod, a second rod, a sleeve assembly, a regulating assembly, an elastic element, a first steel cable, and a second steel cable. The first rod pivotally connects with the bearing unit, the second rod pivotally connects with the first rod, and the sleeve assembly pivotally connects with the second rod. The regulating assembly is disposed in the sleeve assembly, the elastic element is disposed in the second rod, the first steel cable is connected to the elastic element and the first rod respectively, and the second steel cable is connected to the elastic element and the regulating assembly respectively. The sleeve assembly is operated to drive the regulating assembly to move, so that the second steel cable, the elastic element, and the first steel cable move simultaneously to adjust the tension compensation for the bearing unit.
