Sensor-Guided Rolling Walker for Adaptive Motor Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walking aids for patients with motor restrictions fail to provide adequate support in everyday life, are complex to apply and adapt, and do not effectively address both motor and cognitive limitations, lacking real-time therapeutic feedback and individual adjustment.
Innovation Solution
A walking device with integrated sensors and actuators that generate real-time sensor data for personalized therapy and diagnosis, allowing for closed-loop therapy approaches, adaptive mechanical properties, and multisensory feedback to support users with motor and cognitive restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex exoskeleton systems are used to provide active support, then therapeutic effectiveness is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The exoskeleton system is divided into modular components (first exoskeleton unit and second exoskeleton unit) that can be independently applied to different body parts. This segmentation reduces application complexity while maintaining therapeutic effectiveness, as each module can be configured and adjusted separately rather than requiring complete system installation.
Solution Approach 2:
The control system dynamically adapts support parameters based on real-time sensor data and regulatory models. The exoskeleton units can adjust their mechanical properties and support levels during operation, allowing the system to remain effective across varying user conditions without requiring complex manual reconfiguration.
2Ease of operation
If passive walking aids are used, then ease of operation is improved, but therapeutic effectiveness deteriorates
Solution Approach 1:
The exoskeleton system automatically monitors user condition through integrated sensors and autonomously adjusts support parameters based on pre-configured regulatory models. This self-adjusting capability maintains therapeutic effectiveness without requiring continuous user intervention or complex operation, preserving ease of use.
Solution Approach 2:
The system incorporates sensor data acquisition and feedback loops that continuously monitor user performance and automatically adjust therapeutic parameters. This closed-loop control enables the device to adapt to changing user needs in real-time, maintaining high therapeutic effectiveness while requiring minimal user input.

AI summary
The present disclosure relates to a rolling walking device for the therapy and diagnosis of a person with a motor restriction. The walking device comprises at least one axis and a plurality of wheels, a support device for the person, which is configured such that the person can sit on the support device while using the walking device and simultaneously rest with the front of their upper body, and, optionally, with the head, at least partially on the support device, and one or more sensors configured to generate sensor data associated with a therapeutic interaction of the person with the walking device.
