Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices, such as smart watches, provide exercise guidance based on heart rate information but fail to continuously monitor body temperature, which is crucial for adjusting exercise intensity due to increased heat stress during physical activity.
Innovation Solution
An electronic device that includes a sensor module to continuously monitor body temperature, determine exercise capacity by comparing sleep and non-sleep skin temperatures, and provide personalized exercise guidance based on these measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional electronic devices provide exercise guidance based only on heart rate information, then the device complexity is low, but the measurement precision of exercise capacity is insufficient
Solution Approach 1:
The patent combines multiple monitoring functions (heart rate monitoring, skin temperature sensing, exercise state detection) into a single electronic device system. The processor integrates data from the sensor module (including temperature sensor and heart rate sensor) to comprehensively determine exercise capacity, resolving the contradiction by merging multiple measurement capabilities into one device.
Solution Approach 2:
The electronic device performs multiple functions: it monitors heart rate, measures skin temperature, detects exercise states, and provides exercise guidance. The sensor module and processor work together to enable the device to serve as both a heart rate monitor and a temperature monitoring system, achieving multi-functionality that improves measurement precision without proportionally increasing complexity.
2Reliability
If the device continuously monitors body temperature during exercise, then the reliability of exercise guidance is improved, but the use of energy increases
Solution Approach 1:
The processor controls the sensor module to measure skin temperature at periodic intervals during exercise rather than continuously. The patent specifies that temperature measurement is performed at predetermined time intervals, which reduces energy consumption while still providing reliable exercise guidance by capturing temperature trends over time.
Solution Approach 2:
The measurement frequency is dynamically adjusted based on exercise state. The processor detects exercise states and adjusts the monitoring frequency accordingly - increasing monitoring during intense exercise when reliability is most needed, and reducing frequency during low-intensity periods to conserve energy.
3Adaptability or versatility
If the device provides detailed exercise guidance based on multiple parameters, then the adaptability of the service is improved, but the device complexity increases
Solution Approach 1:
The processor determines exercise capacity by analyzing changes in multiple parameters (heart rate, skin temperature, exercise state) and provides guidance based on these parameter variations. The system adapts guidance by detecting parameter changes over time and adjusting recommendations accordingly, achieving high adaptability through parameter analysis rather than complex system architecture.
Solution Approach 2:
The electronic device automatically processes sensor data and generates exercise guidance without requiring complex user input or manual configuration. The processor autonomously integrates heart rate, temperature, and exercise state data to determine exercise capacity and provide personalized guidance, reducing the need for complex control interfaces and user interaction systems.
