Knob Adjustable Elastic Wrist Guard with Traction Wire Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrist guards lack an efficient mechanism for adjusting elasticity, leading to discomfort and inadequate protection during postoperative rehabilitation, as each individual's tolerance to elastic force varies.
Innovation Solution
A knob adjustable elastic wrist guard featuring a guard body with a sheath, bib portion, and elastic band, where a knob and traction wire system allows for easy adjustment of tension by threading through lugs, similar to shoelace tightening, ensuring customizable fit and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a general protector is used with fixed elasticity, then the protective effect is achieved, but the comfort and adaptability for different users is poor
Solution Approach 1:
The wrist guard incorporates a dynamic adjustment mechanism with a knob and traction wire that allows the elasticity to be changed from fixed to adjustable. The traction wire can be tightened or loosened by rotating the knob, enabling the device to adapt to different users' elastic tolerance levels while maintaining reliable protective effect.
2Adaptability or versatility
If the elasticity is adjusted in existing protectors, then adaptability is improved, but the ease of operation and adjustment convenience deteriorates
Solution Approach 1:
The adjustment mechanism is designed to be user-friendly and self-contained. The knob and traction wire system allows users to easily adjust the elasticity themselves without requiring complex tools or procedures. The traction wire threads through lugs and can be quickly tightened or loosened by simple rotational motion of the knob, making the adjustment process convenient and intuitive.
3Adaptability or versatility
If a complex adjustment mechanism is used, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The adjustment mechanism is segmented into distinct functional components: a knob for rotation, a traction wire for tension transmission, and threading lugs for anchoring. This segmentation allows each component to perform its specific function simply and efficiently, avoiding the need for a complex integrated mechanism while achieving reliable elasticity adjustment.
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 wrist guard provides a comfortable and adjustable fit for both left and right hands, allowing users to tailor the elasticity for optimal protection and recovery, enhancing the rehabilitation process.
Implementation Method 1
the knob makes the traction wire wind up or loosen, thus adjusting the tension force of the traction wire on the elastic band
Implementation Method 2
it is often necessary to add a wrist brace to protect the wrist and allow for better recovery
