Wearable–Display Linkage for Wrist-Free Motion Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable devices require additional operations to view real-time motion data, which can be inconvenient and pose safety risks during exercises like cycling or rowing.
Innovation Solution
A method for linkage transmission between a wearable device and a display device, enabling real-time motion data to be automatically collected and displayed on a secondary terminal without requiring the user to raise their wrist, using Bluetooth, NFC, or RFID for communication, and optimizing data transmission modes based on user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time motion data is displayed on the wearable device, then the user can view exercise data, but the user must raise their wrist which interrupts exercise and poses safety risks
Solution Approach 1:
The patent introduces a second terminal device as an intermediary to display motion data. The wearable device (first terminal) collects and transmits motion data to the second terminal device, which then displays the data. This mediator approach allows users to view real-time motion data without needing to raise their wrist, thus maintaining exercise continuity while providing data access.
2Ease of operation
If motion data is transmitted to a second terminal device, then viewing convenience is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic transmission mode selection based on user needs and exercise scenarios. The system can switch between different transmission frequencies and data update rates. For example, during high-intensity exercise where continuous viewing is not needed, the transmission frequency is reduced to save power. When the user needs to view data, the system increases transmission frequency temporarily, then reduces it again, making the power consumption dynamic rather than static.
Solution Approach 2:
The system changes transmission parameters such as data sampling frequency, transmission interval, and data volume based on exercise type and user behavior patterns. Different exercise scenarios have different power consumption requirements and viewing needs, so the system adjusts transmission parameters accordingly to optimize the balance between viewing convenience and power consumption.
3Loss of information
If continuous data transmission is implemented, then real-time data availability is improved, but power consumption and data loss increase
Solution Approach 1:
The patent implements periodic data transmission instead of continuous transmission. The system transmits motion data at regular intervals or based on trigger events (e.g., when the user looks at the second terminal device). This periodic approach ensures that data is available when needed while avoiding unnecessary continuous transmission that would waste power and potentially cause data loss due to buffer overflow or memory constraints.
