Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensing devices are used to comprehensively analyze gait parameters, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines pressure detection devices and limb sensing devices into an integrated gait evaluation system. The pressure detection device captures plantar pressure distribution while the limb sensing device records joint angles and movement, merging multiple measurement functions into a coordinated system that comprehensively analyzes gait parameters for fall risk assessment
Solution Approach 2:
The gait evaluation system is designed with multi-functionality to assess various gait parameters including stride length, step width, gait speed, and joint angles simultaneously. This universal approach allows the system to evaluate different aspects of gait quality through a single integrated platform, improving measurement precision across multiple parameters
2Reliability
If comprehensive gait analysis is performed to predict falls accurately, then reliability of fall prediction is improved, but loss of time in data processing increases
Solution Approach 1:
The system performs preliminary action by continuously collecting and pre-processing gait data during normal walking activities. Pressure values and limb movement data are captured and stored in advance, allowing the system to have gait information ready for rapid analysis when fall risk assessment is needed, reducing processing time while maintaining prediction reliability
Solution Approach 2:
The system implements feedback mechanisms where gait evaluation results are continuously monitored and used to adjust assessment parameters. The processor analyzes pressure distribution patterns and limb movement data in real-time, providing ongoing feedback about gait quality changes that enables timely fall risk prediction without requiring extensive batch processing
