Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensor platforms are used to sense different biometric data, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines ECG sensors, bio impedance sensors, strain gauge sensors, and electro-muscular stimulator sensors into a single fabric band device. Multiple sensors that would traditionally require separate platforms are integrated into one unified system, reducing device complexity while maintaining the ability to sense multiple biometric parameters accurately
Solution Approach 2:
The fabric band is designed as a universal platform that can sense multiple types of biometric data (ECG, bio impedance, strain) and provide electro-muscular stimulation through the same device. This multi-functional design eliminates the need for multiple specialized sensor platforms
2Measurement precision
If traditional sensor arrangements are used, then measurement precision is maintained, but ease of operation deteriorates due to bulkiness and discomfort
Solution Approach 1:
The patent uses a fabric band as the structural base for housing all sensors, replacing traditional rigid sensor housings. The flexible fabric construction allows the device to conform to the body, providing comfort while maintaining sensor functionality and measurement precision
Solution Approach 2:
The device integrates multiple sensor types (ECG, bio impedance, strain gauge) and an electro-muscular stimulator into a composite fabric band structure. This composite design combines the flexibility of fabric with the functionality of multiple sensors, achieving both comfort and accurate biometric sensing
