Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an efficient method to acquire and analyze performance data for users engaged in various activities, such as sports or physical training, which limits personalized feedback and improvement strategies.
Innovation Solution
A wearable sensor device that attaches to clothing or equipment, collecting data on user movement and environmental factors, and transfers this information to a computing device for processing and analysis, generating summary values to assess performance and provide actionable insights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If no performance analysis system is implemented, then system complexity remains low, but performance data collection and analysis capability is insufficient
Solution Approach 1:
The system is divided into separate functional modules: wearable sensor device for data collection, communication device for data transmission, and computing device for data analysis. This segmentation allows each component to be optimized independently while maintaining overall system functionality, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
A communication device acts as an intermediary between the wearable sensor device and the computing device. This intermediary handles data transmission and preliminary processing, reducing the complexity burden on both the sensor device and computing device while enabling comprehensive performance analysis capabilities.
2Loss of information
If comprehensive performance analysis is implemented, then user feedback quality improves, but data processing time increases
Solution Approach 1:
The system performs preliminary data processing and analysis during the activity itself, generating real-time feedback. By preparing and processing data as it is collected rather than analyzing all data after completion, the system reduces post-processing time while maintaining comprehensive feedback quality.
Solution Approach 2:
The system implements continuous feedback loops where performance data is analyzed and fed back to users in real-time or near-real-time. This allows for immediate performance adjustments and reduces the need for extensive post-activity analysis, thereby reducing overall data processing time while maintaining feedback quality.
Data Source
AI summary
A system may use a sensor device affixed to the user or an article of clothing of the user to provide information on performance of an activity. For example, a sensor device may be affixed to a portion of the laces on footwear of the user. Acquired data from the sensor device may be processed to provide analysis information to the user about the performance.
