Wearable Sensor Module Segmentation for Athletic Posture Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitness monitoring devices for athletic activities are often non-portable, heavy, lack battery and processing power, and provide inaccurate or limited feedback, making them unsuitable for real-world competitive or training sessions, and fail to offer insightful comparisons or training regimen suggestions.
Innovation Solution
A sensor garment integrated with a single-purpose sensor module that transmits data via a radio antenna, including a processor, power source, memory, acceleration sensor, magnetic field sensor, and transceiver, to monitor and provide feedback on athletic performance metrics such as spatial orientation, heart rate, and movement data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing fitness monitoring devices are made portable, then they can be used in real-world athletic activities, but they become too heavy or lack sufficient battery and processing power
Solution Approach 1:
The system divides the monitoring functionality into two separate components: a lightweight sensor module worn by the athlete during activity, and a separate processing unit that handles complex data analysis. This segmentation allows the wearable portion to remain light and portable while the heavier processing components are located elsewhere.
Solution Approach 2:
The sensor module is integrated into or attached to athletic equipment (such as a soccer ball), nesting the monitoring functionality within existing equipment rather than requiring a separate wearable device. This eliminates the need for additional weight on the athlete's body.
2Ease of operation
If existing fitness monitoring devices are made portable, then they can be used in real-world athletic activities, but they lack sufficient battery and processing power
Solution Approach 1:
The system separates power-intensive processing functions from the wearable sensor module. Complex data analysis, performance determination, and feedback generation are performed by a separate processing unit with sufficient power capacity, while the wearable portion only performs lightweight sensing and data transmission.
Solution Approach 2:
A wireless communication interface acts as an intermediary between the lightweight sensor module and the powerful processing unit. This allows the sensor module to remain portable with minimal battery requirements while still accessing the full processing power of the external system through wireless data transfer.
3Ease of operation
If existing fitness monitoring devices provide simple performance determinations, then they are easy to use, but they fail to provide accurate advanced determinations or insightful feedback
Solution Approach 1:
The system implements multi-level feedback mechanisms that provide both simple real-time performance metrics during activity and comprehensive advanced analysis after activity. The feedback is tailored to different user needs, offering quick performance checks during exercise and detailed insights for training optimization afterward.
Solution Approach 2:
The system performs preliminary data collection and basic processing during the athletic activity, capturing raw sensor data in real-time. More complex analysis and advanced performance determinations are performed afterward when full processing power is available, allowing both simple real-time feedback and accurate advanced analysis.
