Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional rehabilitation systems are used, then the structure is simple, but the monitoring precision and control effectiveness are insufficient
Solution Approach 1:
The system divides the rehabilitation monitoring function into separate sensor modules that can independently measure different parameters (joint angles, resistance, speed). This segmentation allows for precise monitoring of each parameter while keeping individual sensor components relatively simple, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent implements feedback mechanisms where sensor data is continuously transmitted to processors that adjust rehabilitation parameters in real-time. This feedback loop enhances monitoring precision and control effectiveness without requiring overly complex manual intervention systems, as the automated feedback handling manages the complexity.
2Reliability
If real-time monitoring and control is implemented, then the rehabilitation effectiveness is improved, but the device complexity increases
Solution Approach 1:
The control system is designed with multi-functional processors that can handle multiple rehabilitation protocols and parameters through a unified platform. This universality allows real-time monitoring and adjustment of multiple parameters (angles, resistance, speed) without proportionally increasing complexity, as the same hardware infrastructure supports various rehabilitation functions.
Solution Approach 2:
The system incorporates automated control algorithms that independently adjust rehabilitation parameters based on sensor feedback without requiring constant manual intervention. This self-service capability enhances rehabilitation effectiveness through consistent real-time adjustments while reducing the operational complexity burden on users and therapists.
3Productivity
If granular control over rehabilitation devices is enabled, then the productivity of rehabilitation is enhanced, but the ease of operation decreases
Solution Approach 1:
The patent replaces manual mechanical adjustment systems with automated electronic control based on sensor feedback. processors automatically calculate and adjust resistance and speed parameters based on real-time joint angle data, eliminating the need for manual calculation and adjustment by operators. This substitution enhances rehabilitation productivity through precise granular control while maintaining ease of operation, as the automated system handles the complexity of parameter adjustment.
