3D Knee Orthotic Exoskeleton for Adjustable Load Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing knee joint diagnosis systems only diagnose damage type and severity but do not monitor treatment status in real-time and lack non-invasive treatment methods for gonarthrosis, particularly for mild cases, and invasive methods like surgery are risky for severe cases.
Innovation Solution
A knee joint orthotic device manufacturing apparatus and method that constructs a 3D model of the joint, simulates a transition state for symptom improvement, and designs an exoskeleton mold to disperse load pressure, allowing for non-invasive natural healing or regenerative treatment through stem cell injection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgery is performed for severe gonarthrosis, then treatment effectiveness is improved, but patient risk and burden increase
Solution Approach 1:
The patent introduces an intermediary treatment approach using orthotic devices and non-invasive therapies between conservative treatment and surgery. The orthotic device serves as a mediator that applies controlled forces and pressures to the knee joint, providing therapeutic effects without the risks of surgical intervention.
Solution Approach 2:
The patent replaces the mechanical surgical intervention with a non-invasive mechanical orthotic system. Instead of physically cutting and reconstructing joint structures through surgery, the orthotic device uses external mechanical forces, pressures, and positioning to achieve treatment goals.
2Object-affected harmful factors
If conservative treatment is used for mild gonarthrosis, then patient risk is reduced, but treatment effectiveness may be insufficient
Solution Approach 1:
The orthotic device incorporates dynamic adjustment capabilities, allowing treatment parameters such as pressure, angle, and positioning to be continuously modified based on patient response and treatment progression. This dynamic approach enables conservative treatment to remain effective while adaptable to changing conditions.
Solution Approach 2:
The patent utilizes parameter changes in the orthotic device settings (pressure magnitude, application duration, joint positioning angles) to optimize treatment effectiveness for mild cases while maintaining safety. By precisely controlling these parameters, the treatment achieves sufficient efficacy without requiring invasive procedures.
3Manufacturing precision
If detailed 3D modeling is performed for orthotic device design, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent performs detailed 3D scanning and modeling of the patient's knee joint structure before orthotic device manufacturing. This preliminary action captures precise anatomical data that guides subsequent device fabrication, ensuring custom fit accuracy while streamlining the overall manufacturing process through digital planning.
Solution Approach 2:
The patent creates a digital 3D copy of the patient's knee joint anatomy using scanning technology. This digital replica serves as a template for orthotic device design and manufacturing, allowing precise customization without requiring complex physical trial-and-error fitting procedures.

AI summary
Noninvasive natural healing in daily life or regenerative cell treatment can be promoted. A knee joint model is constructed by three-dimensionally analyzing measurement data obtained by measuring an outline shape and internal space shape of a knee joint part of a subject; a transition state towards an orthotic direction for a symptom improvement of the knee joint part is simulated continuously or stepwisely with reference to the knee joint model; and an exoskeleton mold capable of continuously or stepwisely finely adjusting the knee joint part towards the orthotic direction is designed based on the transition state.
