Walking Stick Data Synchronization via Timestamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor activity sticks with integrated electronics face challenges in synchronizing data between pairs, leading to incorrect interpretation due to communication delays during training sessions.
Innovation Solution
The sticks utilize wireless data transmission networks for synchronized data recording and association through timestamping, ensuring accurate data synchronization and subsequent error-free processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio communication is used to synchronize sticks, then data transmission between sticks is enabled, but communication delays cause incorrect data association
Solution Approach 1:
The system performs preliminary synchronization by establishing a common reference time before data recording begins. Each stick's electronic unit is configured to record data at predetermined time intervals based on this pre-established reference, ensuring that data from both sticks are associated correctly without relying on real-time communication during the actual motor activity session.
2Loss of information
If continuous data recording is performed, then complete motor session data is captured, but data processing complexity increases
Solution Approach 1:
Instead of continuously processing data streams, the system uses periodic sampling at predetermined time intervals. Each electronic unit records data at these fixed intervals based on the synchronized reference time, which reduces the volume of data requiring processing while maintaining complete representation of the motor session through the periodic capture of key moments.
