Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The pairing process for wearable devices with mobile terminals is complex and does not fully utilize the characteristics of wearable devices, leading to inefficient user experience and operation.
Innovation Solution
A method where the mobile terminal and wearable device use synchronized motion information as pairing keys, allowing the mobile terminal to generate a pairing request or respond to a pairing request based on matching motion parameters and time, enabling direct pairing and connection without the need for additional requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pairing process is used for wearable devices, then pairing can be achieved between devices, but the pairing process becomes complex and user experience deteriorates
Solution Approach 1:
The wearable device automatically generates motion information as a pairing key and initiates pairing requests without requiring manual user input. The system self-services the pairing process by using the device's inherent motion characteristics (wearing detection, arm movement patterns) to create and verify pairing credentials, eliminating the need for users to manually enter passwords or follow complex pairing procedures
Solution Approach 2:
The patent replaces traditional manual pairing operations (button pressing, password entry) with motion-based authentication. The mechanical motion of wearing the device and moving the arm is captured by sensors and transformed into digital pairing keys, substituting physical interaction with automated motion recognition and verification
2Reliability
If traditional pairing process is used for wearable devices, then pairing can be achieved between devices, but operation efficiency deteriorates
Solution Approach 1:
The wearable device continuously collects and pre-processes motion information in the background, maintaining ready-to-use pairing keys before pairing is actually needed. When pairing is initiated, the authentication can proceed immediately using pre-computed motion data, eliminating the need for real-time motion capture during the pairing moment and significantly reducing pairing latency
3Volume of moving object
If wearable devices are made portable and simple, then device size is reduced, but power management requirements increase
Solution Approach 1:
The motion information used for pairing is derived from the device's normal operational sensors (accelerometers, gyroscopes) that are already active for other functions like step counting and activity tracking. The system reuses existing sensor data and processing pipelines rather than activating dedicated pairing hardware, thereby avoiding additional power consumption while enabling pairing functionality
Solution Approach 2:
The motion sensors and processing circuits serve dual purposes: they function both for the wearable device's primary fitness tracking operations and for generating pairing authentication keys. This multi-functionality eliminates the need for separate dedicated pairing hardware, maintaining compact size while avoiding additional power drains from redundant components

AI summary
The present invention provides a mobile terminal includes a first information recording unit configured to record first motion information of the mobile terminal, and a first pairing processing unit configured to generate a first pairing request. The first pairing request includes the first motion information which will be used as a pairing key, or a second pairing request is parsed. The second pairing request is received from a wearable device by a first data interaction unit, and the second pairing request includes second motion information from the wearable device which will be used as a pairing key. When the second motion information matches the first motion information, the first pairing processing unit generates a response message for the second pairing request, to realize pairing and connection between the mobile terminal and the wearable device. The present invention further provides a wearable device and a pairing method.
