Solution Overview
Problem
Wearable electronic devices face challenges in accurately transmitting biometric information during exercise due to battery power consumption and accuracy issues related to transmission intervals, with frequent updates consuming power and infrequent updates leading to inaccurate exercise information.
Innovation Solution
A wearable electronic device equipped with sensors, a communication circuit, and a processor that adjusts the transmission interval of sensor context information based on changes in the user's exercise state, allowing for efficient data transmission while maintaining accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wearable electronic device transmits biometric information frequently to the electrical exercise machine, then the accuracy of exercise information is improved, but the battery power consumption increases
Solution Approach 1:
The patent applies dynamics by making the transmission interval adjustable rather than fixed. The processor dynamically changes the transmission interval between first and second intervals based on whether the current interval is the first or second interval, creating a variable transmission strategy that adapts to different operational states to balance accuracy and power consumption
Solution Approach 2:
The patent implements periodic action through alternating transmission intervals. Instead of continuous or fixed-interval transmission, the system uses two different intervals (first and second intervals) that alternate periodically, allowing the device to achieve accurate exercise information while reducing overall power consumption through the longer second interval
2Use of energy by moving object
If the wearable electronic device transmits biometric information at long intervals to save power, then the battery power consumption is reduced, but the accuracy of exercise information deteriorates
Solution Approach 1:
The system dynamically adjusts transmission frequency by alternating between two intervals rather than using a single fixed interval. This dynamic approach ensures that accuracy requirements are met during critical periods (first interval) while power consumption is reduced during other periods (second interval)
Solution Approach 2:
The patent uses periodic action with alternating transmission intervals where the device switches between transmitting at the first interval and the second interval. This periodic alternation allows the system to achieve both power savings and acceptable accuracy by distributing transmission frequency over time

AI summary
Disclosed is a wearable electronic device including: at least one sensor, a communication circuit, a processor, and a memory. The memory may store instructions that, when executed, cause the processor to: obtain sensor context information including information associated with an exercise state of a user of the wearable electronic device, control the wearable electronic device to transmit the sensor context information to an external electronic device at a second interval, adjust an interval of transmission of the sensor context information to a first interval based on a change of the sensor context information, and transmit the sensor context information to the external electronic device at the first interval using the communication circuit.
