Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors and data processing components are integrated into the shoe, then measurement precision and functionality are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple sensing functions (pressure sensing and movement detection) into a single integrated shoe device. The sensor device includes both pressure sensors mounted on the insole and an accelerometer integrated into the shoe structure, allowing simultaneous measurement of multiple parameters without requiring separate devices.
Solution Approach 2:
The sensor device is designed to perform multiple functions: measuring vertical forces through pressure sensors, detecting movement through the accelerometer, providing real-time feedback through alert mechanisms, and recording data for later analysis. This multi-functional approach consolidates what would traditionally require multiple separate devices into one universal monitoring system.
2Reliability
If real-time feedback and data recording capabilities are added, then rehabilitation guidance effectiveness is improved, but device complexity and cost increase
Solution Approach 1:
The patent incorporates a feedback mechanism that provides real-time information to the user during rehabilitation exercises. The alert mechanism (visual or audible) immediately notifies the user when predetermined force or movement thresholds are exceeded, allowing for immediate correction of improper exercise technique.
Solution Approach 2:
The system pre-sets threshold values for force and movement that represent correct exercise form. Before the user begins exercising, these thresholds are programmed into the device, allowing the system to automatically compare real-time measurements against the correct parameters and provide feedback without requiring real-time analysis by a professional.
3Adaptability or versatility
If the sensor device is made adaptable to different shoe sizes, then ease of operation and user comfort are improved, but manufacturing precision requirements increase
Solution Approach 1:
The sensor device is divided into modular components: the insole with pressure sensors can be separately manufactured and then installed in the shoe. This segmentation allows the sensing elements to be precisely positioned during assembly rather than requiring extreme precision in the shoe manufacturing process itself, accommodating various shoe sizes while maintaining sensor accuracy.
