Walking Training Apparatus with Movable Joint Robot Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walking assist devices during rehabilitation training shift the weight of the device to the user, causing discomfort and inefficiency due to their design, which fails to securely support the user's weight and the device's own weight effectively.
Innovation Solution
A walking training apparatus featuring a joint motion robot with a horizontal and vertical movable unit, a counterload unit, and a control system that adjusts the position and load of the joint motion robot to prevent weight shifting, ensuring secure and comfortable training by synchronizing the treadmill speed with the user's movements and adjusting the robot's position based on user data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a typical walking assist device supporting device with parallelogram structure is used, then the device can move up-and-down according to rehabilitation training, but the own weights of the patient and the walking assist device are shifted to the walking trainee through the treadmill belt
Solution Approach 1:
The supporting device is divided into separate functional modules: a lower frame for structural support, a coupling unit for the walking assist device, and carriers connecting them. This segmentation allows independent optimization of weight support and device coupling functions, enabling the weight support function to be separated from the user to eliminate harmful weight shifting.
Solution Approach 2:
The treadmill belt is introduced as an intermediary element that supports the weight of both the patient and the walking assist device independently. The belt acts as a mediator that bears the combined load without transmitting it to the user, thereby eliminating the harmful effect of weight shifting while maintaining proper support during rehabilitation training.
2Adaptability or versatility
If the walking assist device moves back and forth in accordance with height change determined by parallelogram structure, then the device can adapt to walking motion, but the walking trainee is not securely supported and feels uncomfortable
Solution Approach 1:
The supporting device incorporates dynamic elements including a movable lower frame and adjustable carriers that can adapt their position and orientation during rehabilitation training. This dynamic configuration allows the device to maintain secure support while adapting to the walking motions and height changes of the patient, resolving the contradiction between adaptability and secure support.

AI summary
The present invention relates to a walking training apparatus. The walking training apparatus includes: a treadmill providing a bottom surface to allow a user who is training to walk to do so in a stationary position; a user counterweight unit including a counterweight, a wire, and a harness jacket, wherein the user counterweight unit lifts the user's body upward in order to reduce the load from the user's weight; a joint motion robot worn on one lower leg of the walker, wherein the joint motion robot is constituted by a hip-joint motion part, a knee-joint motion part, and an ankle-joint motion part; a joint motion robot support part supporting and coupled to the joint motion robot to reduce the load of the weight of the joint motion robot, wherein the joint motion robot support includes a horizontal movable part and a vertical movable part for moving the joint motion robot; and a control unit linked with at least one of the treadmill, the user counterweight unit, the joint motion robot, and the joint motion robot support in order to generate a customized control signal according to the user and to transmit the signal.
