Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gait training systems fail to provide a dynamic and adjustable reverse load that aligns with the subject's real-time physical conditions, leading to inefficient and potentially unsafe gait training due to insufficient load adjustment and compensation.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed reverse load weight is applied to the subject, then the device structure is simple, but the load cannot be adjusted according to real-time physical conditions, reducing training effectiveness and safety
Solution Approach 1:
The reverse load weight is changed from a fixed value to a dynamically adjustable value that can be modified in real-time based on the subject's physical conditions and training progress. The control unit receives input signals and adjusts the reverse load weight accordingly, enabling the system to adapt to changing training requirements while maintaining a relatively simple overall structure.
Solution Approach 2:
The system incorporates a detection unit that monitors the subject's physical conditions and provides feedback to the control unit. Based on this feedback, the control unit automatically adjusts the reverse load weight to optimize training effectiveness and ensure safety, creating a closed-loop control system that responds to real-time changes in the subject's state.
2Reliability
If the reverse load weight is adjusted frequently to match real-time conditions, then training safety and effectiveness improve, but the device complexity and control difficulty increase
Solution Approach 1:
The detection unit continuously monitors the subject's physical conditions and automatically triggers adjustments to the reverse load weight through the control unit without requiring external intervention. This self-service mechanism ensures that the system responds promptly to changes in training conditions, maintaining high reliability while keeping the control logic relatively simple and automated.
3Measurement precision
If a detection unit is added to measure reverse load weight in real-time, then load adjustment precision improves, but the device complexity and cost increase
Solution Approach 1:
The detection unit is designed to perform multiple functions: measuring the subject's physical conditions, monitoring training progress, and providing data for automatic control adjustments. By consolidating these functions into a single integrated detection system, the patent achieves high measurement precision while minimizing the increase in overall device complexity compared to having separate systems for each function.
