Swim Goggle Sensor System with Extracted Display for Accurate Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring and tracking exercise activity metrics are often obtrusive, difficult to use, prone to inaccurate data collection, and unreliable.
Innovation Solution
A swim race data capture system and an exercise activity monitoring system integrated with eyewear, featuring an inertial measurement unit and a modular design that secures the system to the eyewear without obstructing the user's field of vision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a monitoring system is integrated into eyewear for exercise activity tracking, then data collection accuracy is improved, but the system becomes obtrusive and distracting to the user
Solution Approach 1:
The display function is extracted and removed from the eyewear system entirely. The patent explicitly states 'the sensor system does not include a display' and 'does not include a display configured to project light from the housing,' eliminating the source of visual distraction while preserving the inertial measurement and data collection capabilities for accurate exercise tracking.
Solution Approach 2:
The system is segmented into separate functional components: the inertial measurement unit for data collection, the housing for structural support, and the exclusion of display components. This segmentation allows the monitoring function to operate independently without the distracting element of a display, resolving the contradiction between measurement precision and user distraction.
2Loss of information
If a display is added to the sensor system housing, then real-time feedback is improved, but the system becomes more complex and potentially distracting
Solution Approach 1:
The display component is extracted and removed from the system. The patent explicitly states 'the sensor system does not include a display' and 'does not include a display configured to project light from the housing in an installed configuration,' simplifying the device while maintaining core monitoring functionality through the inertial measurement unit.
3Reliability
If the sensor system is securely fixed within the eyewear inner cavity, then measurement reliability is improved, but the housing design becomes more complex
Solution Approach 1:
The housing is merged with the eyewear structure, where the housing configured to be retained within the inner cavity of the eye goggle integrates the sensor system securely. The patent states 'the housing is configured to be retained within an inner cavity of an eye goggle in a fixed position relative to the eye goggle,' combining structural support and sensor mounting into a unified design that ensures reliability without excessive complexity.
4Ease of operation
If the sensor system includes removable disposal within the inner cavity, then ease of operation is improved, but the fixed position requirement becomes more difficult to maintain
Solution Approach 1:
The system incorporates dynamic characteristics by allowing the sensor system to be removably disposed within the inner cavity while maintaining a fixed position during operation. The patent states 'the sensor system configured to be removably disposed within the inner cavity' and 'in a fixed position relative to the eye goggle,' enabling easy installation and removal while ensuring stable positioning during exercise activities.
Data Source
AI summary
A swim race data capture system includes an eye goggle configured to be biased against a face of a wearer and to circumscribe an eye of the wearer. The eye goggle defines an inner cavity, and the swim race data capture system further includes a sensor system configured to be removably disposed within the inner cavity in a fixed position relative to the eye goggle. The sensor system includes an inertial measurement unit and does not include a display.
