Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing knee joint rehabilitation instruments face difficulties in correctly positioning the leg during rehabilitation exercises due to structural limitations, making it challenging to efficiently perform knee rehabilitation.
Innovation Solution
A knee joint rehabilitation instrument featuring a thigh fixing unit, a shin fixing unit, and a knee position guide that guides the knee into the correct position, with adjustable components such as elastic belts, shock absorbers, and a motor-controlled system for easy use and effective rehabilitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing knee joint rehabilitation instruments are used, then rehabilitation exercises can be performed, but it is difficult to correctly position the leg due to structural limitations
Solution Approach 1:
The device is divided into distinct functional modules: a thigh fixing unit with elastic belt and shock absorbers, a shin fixing unit, and a separate knee position guide component. This segmentation allows each part to perform its specific function independently, making the overall device easier to operate while maintaining manageable structural complexity
Solution Approach 2:
A knee position guide is introduced as an intermediary component between the thigh fixing unit and shin fixing unit. This guide features a through-hole that visually indicates the correct knee position, serving as a mediator that facilitates proper leg positioning without requiring complex adjustment mechanisms
2Productivity
If the leg is not positioned correctly during rehabilitation, then the rehabilitation exercises can still be performed, but efficiency is reduced
Solution Approach 1:
The knee position guide incorporates visual indicators (through-holes) that allow users to visually confirm correct knee positioning. This visual feedback mechanism enables users to accurately determine whether the knee is properly positioned, thereby improving positioning accuracy and subsequently enhancing rehabilitation efficiency
Solution Approach 2:
The knee position guide with its through-hole design allows users to self-assess their knee positioning accuracy without requiring external assistance or complex measurement tools. Users can visually verify correct positioning themselves, making the positioning process both accurate and efficient

AI summary
The present invention relates to a knee joint rehabilitation instrument. The knee joint rehabilitation instrument of the present invention includes a thigh fixing unit into which a thigh of a leg requiring rehabilitation is inserted and thereby fixed; a shin fixing unit which is disposed next to the thigh fixing unit and into which a shin of the leg requiring rehabilitation is inserted and thereby fixed; and a knee position guide which is disposed between the thigh fixing unit and the shin fixing unit and guides a position of a knee when inserting the leg requiring rehabilitation into the thigh fixing unit and the shin fixing unit.
