Wearable Vibration Guidance for 3D Exercise Trajectory Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for teaching, correcting, and monitoring exercise movements in three dimensions are inadequate as they fail to provide active or passive guidance effectively, lacking the ability to actively guide users in a three-dimensional manner and passively correct deviations from the correct movement trajectory.
Innovation Solution
A wearable device equipped with vibration motors and light emitting diodes, connected to a motion processing unit and processor, which provides active instruction by vibrating and illuminating along the correct trajectory path for learning and passive correction by vibrating when the user deviates from the optimal movement pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wearable device provides visual and/or physical feedback to a trainee, then the trainee receives guidance on movement execution, but the feedback cannot actively guide the trainee in a three-dimensional manner along the correct trajectory path
Solution Approach 1:
The patent employs vibration motors distributed around the band to provide tactile feedback that actively guides the user along the correct trajectory path. The vibration motors are activated selectively based on the user's deviation from the optimal movement pattern, providing directional guidance through localized vibration cues that indicate which way to adjust the movement.
Solution Approach 2:
The system continuously monitors movement data through motion processing units and provides real-time feedback through vibration motors and light emitting diodes. The feedback mechanism compares actual movement against the optimal trajectory path and delivers corrective cues when deviations are detected, enabling closed-loop control of exercise form.
2Measurement precision
If a wearable device monitors movement data to determine three-dimensional orientation, then the device can detect deviations from the trajectory path, but the device complexity increases with multiple vibration motors and processing units
Solution Approach 1:
The wearable device divides the band into multiple segments with individually controllable vibration motors distributed around the circumference. This segmentation allows localized feedback at different positions along the band, enabling precise directional guidance without requiring a single complex actuation mechanism.
Solution Approach 2:
The motion processing unit serves multiple functions: it detects three-dimensional orientation, compares movement against the optimal trajectory path, determines deviations, and triggers appropriate vibration motors. This multi-functionality reduces the need for separate dedicated components for each task, thereby managing complexity while maintaining precision.
3Ease of operation
If the wearable device provides active instruction with continuous or intermittent vibration, then the user learns the movement pattern through tactile guidance, but energy consumption increases
Solution Approach 1:
The system employs intermittent vibration rather than continuous vibration for active instruction. The vibration motors are activated in periodic cycles or bursts based on the user's movement phase and deviation detection, providing guidance cues at critical moments while allowing energy conservation during periods when the user is performing movements correctly.
Solution Approach 2:
The system applies vibration feedback selectively and partially—only when and where needed based on detected deviations from the optimal trajectory. Rather than continuously stimulating all vibration motors, the system activates only the specific motors required to guide correction at that moment, reducing overall energy consumption while maintaining learning effectiveness.
