Knob-Adjustable Thumb Protector for Easy Wear and Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thumb protectors for preventing or alleviating thumb tenosynovitis lack ease of wearing, adjustability, and comfort.
Innovation Solution
A knob-type thumb protector with a protector main body, a first and second connecting piece, and a knob adjusting piece, which includes a sleeve hole, a sleeve hole, a sleeve hole, and a connecting groove, and a knob adjusting piece, allowing for easy adjustment of tightness through a rotating knob assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing thumb protectors are designed with simple structure, then manufacturing cost is reduced, but ease of wearing and adjusting tightness deteriorates
Solution Approach 1:
The thumb protector is divided into multiple independent components: a protective body, a connecting piece with groove, and an adjustable fastening system with rope and knob. This segmentation allows each component to be manufactured separately using simple processes while enabling complex adjustment functionality when assembled, resolving the contradiction between manufacturing simplicity and operational complexity.
Solution Approach 2:
The fastening system incorporates a dynamic adjustment mechanism where the rope can be threaded through the groove and secured with a knob, allowing users to adjust tightness dynamically. This transforms a static structure into a dynamically adjustable one, improving ease of operation without requiring complex pre-manufactured components.
2Device complexity
If thumb protectors use fixed tightness design, then structure is simplified, but comfort and adaptability deteriorates
Solution Approach 1:
The fastening system transitions from a fixed tightness design to a dynamically adjustable one using a rope and knob mechanism. The rope can be threaded through the groove in the connecting piece and secured at different positions via the knob, enabling continuous adjustment of tightness to adapt to different users and conditions while maintaining relatively simple structural components.
Solution Approach 2:
The tightness parameter of the thumb protector is made variable through the adjustable fastening system. By changing the position where the rope is secured on the connecting piece, the tightness parameter can be continuously adjusted, providing adaptability without requiring multiple different protector designs.
3Device complexity
If thumb protectors lack adjustment mechanism, then device complexity is reduced, but comfort and user experience deteriorates
Solution Approach 1:
The adjustment function is separated into distinct components: the groove in the connecting piece, the rope, and the knob. This segmentation allows the adjustment mechanism to be added without redesigning the entire protector, maintaining simplicity while improving comfort through adjustable tightness.
