Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional respiration sensing devices are used, then respiration can be monitored, but the devices are bulky and require complex calculations
Solution Approach 1:
The patent extracts the essential respiration sensing function from complex conventional devices by using a simple resistance-based measurement system. The respiration sensing module comprises only necessary components: substrate, electrodes, and stretchable conductive element, eliminating bulky structures and complex calculation systems while maintaining monitoring capability
Solution Approach 2:
The patent replaces complex acoustic or gas flow rate sensing mechanisms with a simple electrical resistance measurement system. By measuring resistance changes of the stretchable conductive element caused by respiration-induced length changes, the system achieves accurate respiration monitoring without requiring complex mechanical or acoustic systems
2Reliability
If conventional respiration sensing devices are used, then respiration can be detected, but accuracy concerns remain and immediate detection of life-threatening conditions is unreliable
Solution Approach 1:
The patent divides the respiration monitoring system into multiple independent sensing modules, each with its own electrodes and stretchable conductive element. This segmentation allows parallel measurement of respiration parameters from different body locations, improving overall reliability and enabling cross-validation of measurements to detect life-threatening conditions accurately
Solution Approach 2:
The patent implements a feedback mechanism where the resistance changes of the stretchable conductive element are continuously measured and processed to determine respiration status. The system provides real-time feedback on respiration patterns, enabling immediate detection of abnormal conditions such as choking or respiratory distress
3Device complexity
If a single respiration sensing module is used, then device simplicity is maintained, but system reliability decreases when module failure occurs
Solution Approach 1:
The patent prepares for potential module failure by incorporating multiple redundant sensing modules into the system. This redundancy acts as a cushion against single module failure, ensuring continuous reliable operation. The system can switch between or combine measurements from multiple modules if one fails, maintaining high reliability without significantly increasing complexity
