Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the patch-type bio signal measuring device transmits biometric data to a smartphone through short-range communication, then the biometric data can be transmitted to a server, but the reliability and accuracy of the biometric data deteriorates due to battery limitations and communication connectivity issues
Solution Approach 1:
The patent introduces a smart watch as an intermediary device between the patch-type bio signal measuring device and the smartphone. The smart watch receives biometric data from the patch device and transmits it to the smartphone or server, thereby mediating the data transmission process and eliminating the direct dependency on the smartphone's battery life for continuous operation
Solution Approach 2:
The patent segments the data transmission system into multiple independent components: the patch-type bio signal measuring device, the smart watch, and the smartphone/server. This segmentation allows each component to operate independently with its own battery, so the smart watch can maintain communication with the patch device even when the smartphone is powered off
2Measurement precision
If the patch-type bio signal measuring device continuously transmits biometric data to ensure complete data collection, then the accuracy of biometric data improves, but the battery capacity of the smart watch depletes faster
Solution Approach 1:
The patent implements periodic action by having the smart watch disconnect and reconnect to the patch-type bio signal measuring device at predetermined intervals. Instead of maintaining continuous communication, the system establishes connections periodically to transmit biometric data, which reduces energy consumption while still ensuring complete data collection over time
Solution Approach 2:
The patent employs feedback mechanisms where the smart watch checks its battery residual quantity before establishing communication with the patch device. Based on this feedback, the system dynamically adjusts communication frequency and connects to candidate devices when battery levels are low, optimizing the balance between data completeness and energy conservation
3Reliability
If the smart watch continuously monitors battery level and manages communication to ensure data transmission, then the reliability of biometric data improves, but the device complexity increases
Solution Approach 1:
The patent implements self-service by enabling the smart watch to autonomously monitor its own battery residual quantity, determine when to disconnect or reconnect to the patch device, and automatically switch to candidate devices without requiring external intervention. This autonomous operation simplifies the overall system management while maintaining high data reliability

AI summary
A biometric data management method includes: measuring a bio signal of a user by a patch-type bio signal measuring device; checking a first residual quantity of a battery of a smart watch; connecting wireless communication between the patch-type bio signal measuring device and the smart watch, and receiving, by the smart watch, first biometric data corresponding to the bio signal measured by the patch-type bio signal measuring device from the patch-type bio signal measuring device; transmitting, by the smart watch, the first biometric data received from the patch-type bio signal measuring device to a server; disconnecting the wireless communication between the patch-type bio signal measuring device and the smart watch, and entering the smart watch into a standby mode; checking, by the smart watch, a second residual quantity of the battery; and transmitting, by the smart watch or the server, information on requested biometric data to a candidate device.
