Walking Training System with Detection Unit for Belt Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walking training systems can cause discomfort for trainees when the treadmill belt is started rotating before they become accustomed to the walking assistance apparatus, leading to anxiety during training.
Innovation Solution
A walking training system that includes an operation unit to output a signal for starting the belt rotation only after a detection unit confirms a predetermined number of walking or stepping operations by the trainee, using load sensors and a controller to maintain an operation prohibition state until the trainee is adequately accustomed, thereby preventing premature belt rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the operator starts the rotational operation of the belt before the walking trainee becomes accustomed to the assistance operation, then the training can start earlier, but the walking trainee may feel uncomfortable and experience anxiety
Solution Approach 1:
The system performs preliminary detection of walking operations before allowing belt rotation to start. The detection unit counts the number of walking operations performed by the trainee, and only after reaching a predetermined threshold does the system permit the belt to rotate. This preliminary action ensures the trainee is sufficiently accustomed to the assistance operation before full training begins, eliminating anxiety while minimizing delay.
2Object-affected harmful factors
If the system requires a predetermined number of walking operations before allowing belt rotation, then trainee comfort is improved, but the training process takes longer
Solution Approach 1:
The system continuously monitors and counts the number of walking operations performed by the trainee through the detection unit. This feedback mechanism provides real-time information about the trainee's adaptation progress, allowing the system to automatically determine when the predetermined threshold is reached and immediately permit belt rotation. This minimizes the time delay while ensuring trainee comfort is achieved.
3Ease of operation
If the operator manually controls the start of belt rotation, then flexibility is maintained, but the risk of premature rotation causing trainee anxiety increases
Solution Approach 1:
The controller acts as an intermediary between the operator and the belt rotation system. Even though the operator can issue a start command, the controller intercepts this command and checks whether the predetermined number of walking operations has been reached. Only if the condition is satisfied does the controller actually initiate belt rotation. This intermediary function maintains operator flexibility while preventing premature rotation that would cause trainee anxiety.

Function Achieved in This Case
This solution reduces anxiety in trainees by ensuring they are comfortable with the assistance apparatus before starting the training, allowing for a more effective and comfortable walking experience.

AI summary
A walking training system capable of suppressing a state in which a walking trainee feels uncomfortable during walking training is provided. A walking training system 1 according to an aspect of the present invention includes a treadmill 31 including a belt 311 on which a walking trainee performs walking training, the belt 311 being moved in a rotational manner; a controller 5 that controls the rotational operation of the belt 311; and a walking assistance apparatus 3 that is mounted on a leg portion of the walking trainee and assists the walking operation of the walking trainee. The walking training system 1 further comprises a detection unit 314 that detects whether the leg portion of the walking trainee on which the walking assistance apparatus 3 has been mounted has performed a walking operation or a stepping operation on the belt 311, and the controller 5 maintains an operation prohibition state in which the rotational operation of the belt 311 is not started until the time that the detection unit 314 detects the walking operation or the stepping operation a predetermined number of times and cancels the operation prohibition state after the detection unit 314 detects the walking operation or the stepping operation the predetermined number of times.
