Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable wristband devices require manual adjustment of the display direction based on whether they are worn on the left or right arm, which is inconvenient for users.
Innovation Solution
A method and system that automatically determine the wearing state of a wearable device by detecting positional changes in a three-dimensional space using a combination of acceleration and gyro sensors, allowing the display direction to be adjusted accordingly without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of display direction is implemented, then the device can adapt to different wearing states, but the operation convenience deteriorates due to requiring user intervention
Solution Approach 1:
The wearable device automatically detects its own wearing state through sensors (accelerometer, gyro sensor) and autonomously adjusts the display direction without requiring user intervention. The system performs self-diagnosis and self-adjustment by monitoring movement patterns and positional changes, eliminating the need for manual configuration while maintaining adaptability to different wearing scenarios
Solution Approach 2:
The device pre-configures multiple wearing state profiles (left wrist, right wrist, different orientations) and uses sensor data to automatically select and apply the appropriate profile before the user needs to view the display. By preparing multiple pre-defined states and automatically switching between them based on detected movement patterns, the system ensures the display is correctly oriented before the user interacts with it
2Ease of operation
If automatic detection of wearing state is implemented, then operation convenience is improved, but device complexity increases due to additional sensors and algorithms
Solution Approach 1:
The wearable device integrates multiple sensors (accelerometer, gyro sensor, touch sensor) that serve dual purposes: they monitor device orientation and movement for wearing state detection, while also providing data for other device functions such as step counting, gesture recognition, and motion-based interactions. This multi-functionality approach allows automatic wearing state detection without proportionally increasing device complexity, as the same hardware resources are leveraged across multiple features
Solution Approach 2:
The system replaces manual mechanical adjustment mechanisms (physical buttons, switches, or manual configuration interfaces) with electronic sensor-based detection and automated software control. Instead of requiring users to physically adjust or manually configure the display orientation, the system uses electronic sensors to detect wearing state and automatically adjusts display parameters through software, reducing mechanical complexity while improving ease of operation

Data Source
AI summary
A method for controlling a wearable device is disclosed. The method includes a step of determining a wearing state of the wearable device based on a positional change of the wearable device. The wearable device can be an annular wearable device worn by surrounding a body part of a wearer, and primarily includes an operation control portion, which is configured to determine a wearing state of the wearable device on the wearer. The wearing state of the wearable device can include a wearing direction of the wearable device, and whether the wearable device is worn on the left arm or the right arm of the wearer. The wearable device can be controlled by certain movements of the wearer, and thus involves no operation interface. A smart control system is also disclosed.
