Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple vital signs sensors are used to detect different physiological parameters, then measurement comprehensiveness is improved, but data synchronization capability deteriorates because sensors transmit at different timings
Solution Approach 1:
Motion information serves as an intermediary to associate vital signs data from different sensors. The system transmits motion information alongside vital signs information, and the receiving device uses this motion information as a reference to synchronize and associate data from multiple sensors, effectively resolving the timing mismatch between simultaneous detections.
2Productivity
If sensors transmit data at their own independent timings, then transmission efficiency is improved, but data correlation capability deteriorates making it impossible to recognize simultaneous detections
Solution Approach 1:
The system preliminarily transmits motion information together with vital signs information from multiple sensors. This preliminary inclusion of synchronization reference data enables the receiving device to later correlate and synchronize the vital signs data without requiring real-time coordination between sensors, maintaining transmission efficiency while preserving temporal correlation.
3Device complexity
If multiple sensors operate independently without coordination, then device complexity is reduced, but synchronization capability deteriorates
Solution Approach 1:
Motion information acts as a mediator that enables synchronization without requiring complex coordination mechanisms between sensors. Each sensor independently transmits its vital signs data along with motion information, and the receiving device uses this shared motion reference to synchronize the data, achieving reliable synchronization with minimal added complexity.
4Reliability
If motion information is transmitted alongside vital signs data, then data synchronization capability is improved, but transmission data volume increases
Solution Approach 1:
Motion information serves multiple functions simultaneously: it acts as a synchronization reference for correlating vital signs data from multiple sensors, and it can also provide additional physiological information. This multi-functionality justifies the increased data transmission volume by delivering both synchronization and diagnostic value.

AI summary
A first vital signs information detecting sensor and a second vital signs information sensor are attached to a living body. The first vital signs information detecting sensor detects over time first vital signs information and first motion information of the living body. The first vital signs information and the first motion information are transmitted from the first vital signs information detecting sensor to a receiver. The second vital signs information detecting sensor detects over time second vital signs information and second motion information of the living body. The second vital signs information and the second motion information are transmitted from the second vital signs information detecting sensor to the receiver. The first vital signs information and the second vital signs information are displayed on a display of the receiver in a synchronized state, on the basis of the first motion information and the second motion information.
