Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a light sensor is used to monitor user activity and control running status, then the device can effectively manage battery endurance, but the manufacturing cost increases significantly
Solution Approach 1:
The patent introduces a motion sensor as an intermediary device to detect user activity status. Instead of using an expensive light sensor directly, the motion sensor captures motion data which then triggers the appropriate running status (working or standby state), achieving the same battery management goal through a cost-effective intermediary mechanism
Solution Approach 2:
The patent uses a motion sensor to create a copy or representation of user activity status through motion detection. This copied information about user behavior (moving vs. stationary) is then used to control the running status, replacing the need for direct light-based detection while maintaining effective battery endurance management
2Measurement precision
If a light sensor is installed in the wearable device, then user activity can be monitored accurately, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the monitoring function from the wearable device itself by utilizing the motion sensor of an associated mobile phone. Instead of incorporating a light sensor into the wearable device structure, the system takes out the detection function and performs it externally through the mobile phone's existing sensors, reducing device complexity while maintaining monitoring accuracy
Solution Approach 2:
The patent leverages the universal motion sensor in mobile phones to serve multiple purposes: it detects user activity for the wearable device, controls the running status, and manages battery endurance. This multi-functional use of an existing sensor eliminates the need for specialized light sensors in the wearable device, reducing overall system complexity

AI summary
A method and an apparatus for controlling a running status of a wearable electronic device, where the method includes determining a posture of a wearable electronic device, where the posture includes a stationary posture and a moving posture, and controlling a running status of the wearable electronic device according to the posture. According to the method and the apparatus for controlling a running status of a wearable electronic device, the posture of the wearable electronic device is monitored using, for example, a gyroscope signal from a mobile phone, whether a user is using the wearable electronic device is determined, and the running status of the wearable electronic device is determined without using a light sensor, which reduces manufacturing costs of the wearable electronic device.
