Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If generalized feedback is provided to all individuals, then the feedback system is simple to implement, but individuals become immune to the feedback and adherence to exercise therapy programs deteriorates
Solution Approach 1:
The system transitions from providing uniform generalized feedback to delivering personalized feedback tailored to each individual's specific pose, performance metrics, and exercise progress. The feedback content, timing, and delivery method are customized based on real-time pose estimation data and individual characteristics, making each individual receive locally optimized feedback rather than a one-size-fits-all approach.
Solution Approach 2:
The system dynamically adjusts feedback parameters such as feedback content, delivery timing, intensity, and modality based on real-time pose estimation data, performance metrics, and individual progress. This allows the feedback system to adapt its characteristics continuously, preventing immune response by constantly varying the feedback parameters according to individual needs and performance states.
2Measurement precision
If real-time pose estimation and personalized feedback systems are implemented, then feedback accuracy and personalization are improved, but system complexity and computational requirements increase
Solution Approach 1:
The system divides the complex task of pose estimation and feedback generation into distinct modular components: key point detection modules, pose estimation modules, performance analysis modules, and feedback generation modules. Each module handles a specific aspect of the process, allowing for independent optimization, easier debugging, and reduced overall system complexity through functional decomposition.
Solution Approach 2:
The system uses template-based approaches where ideal exercise poses and movement patterns are pre-defined as templates. Real-time pose estimates are compared against these templates to generate feedback, avoiding the need to create entirely new feedback logic for each exercise. This template copying and comparison mechanism simplifies the system while maintaining high accuracy.
3Productivity
If manual feedback from healthcare professionals is replaced with automated systems, then reliance on manual feedback is reduced, but measurement precision and reliability of feedback may deteriorate
Solution Approach 1:
The system implements continuous real-time feedback loops where pose estimation results immediately inform feedback generation, which in turn guides exercise performance. This closed-loop feedback mechanism ensures high reliability by continuously monitoring and adjusting feedback based on current pose data, maintaining precision without requiring manual intervention.
Solution Approach 2:
The system performs preliminary actions by pre-defining exercise templates, ideal poses, and feedback rules before actual exercise execution. Healthcare professionals can pre-configure exercise programs and feedback criteria, which are then automatically applied during real-time exercise monitoring. This preliminary setup ensures consistent, reliable feedback while enabling full automation during exercise execution.

AI summary
Introduced here are computer-implemented platforms (also referred to as “motion monitoring platforms”) that are able to provide feedback in a personalized manner during the performance of physical activities. By monitoring the current state of an individual while performing a physical activity, a motion monitoring platform can more readily identify feedback that is likely to have its intended effect.
