Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional rehabilitation assessment methods are used, then the process is simple and requires minimal equipment, but the measurement precision and consistency of evaluation between professionals deteriorates
Solution Approach 1:
The system segments the assessment into multiple components: color image capturing, distance image capturing, sound recognition, pattern matching, and track information generation. Each component processes specific aspects of walking motion independently, then integrates results to provide comprehensive evaluation with high precision while maintaining modular complexity management.
Solution Approach 2:
The patent introduces an intermediary processing system that captures motion data through multiple sensors (color camera, distance sensor), processes the data through pattern matching algorithms, and generates standardized track information. This intermediary layer transforms raw sensor data into consistent, comparable assessment results, improving measurement precision across different professionals while centralizing the complexity in the processing system.
2Reliability
If detailed motion capture technology is implemented, then the analysis detail and objectivity improve, but the device complexity and cost increase
Solution Approach 1:
The system employs multi-functional circuitry that performs multiple assessment tasks: capturing color images for visual analysis, measuring distance for spatial tracking, recognizing sounds for contextual information, and generating comprehensive track information. This universal approach consolidates multiple specialized devices into one integrated system, improving reliability through objective multi-modal data collection while managing complexity through functional integration.
Solution Approach 2:
The system implements feedback mechanisms where captured motion data is processed through pattern matching algorithms that compare observed movements against standardized walking patterns. The generated track information provides objective feedback on walking conditions, enabling reliable, consistent assessment that reduces subjectivity while the centralized processing manages system complexity.
3Loss of time
If real-time motion analysis is provided, then the feedback timeliness improves for rehabilitation guidance, but the processing speed requirements and system complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-configuring pattern matching templates for various walking conditions and pre-establishing processing algorithms. During real-time operation, captured motion data is immediately compared against these pre-prepared patterns, enabling rapid analysis and timely feedback without requiring complex real-time computation of all processing logic, thus reducing real-time processing complexity while maintaining speed.
