Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If integrated solutions are used for augmented reality and virtual reality headsets and glasses, then the system can deliver an adequate augmented reality or virtual reality experience, but the system restricts flexibility, compatibility with prescription eyewear, and integration with everyday tasks
Solution Approach 1:
The system divides the augmented reality functionality into separate modular components that can be independently attached to eyeglass frames. Each module contains specific sensors or displays that can be selectively configured, allowing the system to maintain reliable AR performance while adapting to different eyewear types and user needs.
Solution Approach 2:
The modular modules are designed to be universally compatible with various eyeglass frame types through standardized attachment mechanisms. The same module can be attached to different frames and configurations, enabling the system to work with both prescription and non-prescription eyewear while maintaining consistent AR functionality.
2Reliability
If specially designed headsets or glasses are used for augmented or virtual reality, then the system can provide AR/VR functionality, but people dependent on prescription glasses are restricted from using these devices or required to invest in duplicative vision wear
Solution Approach 1:
By separating the AR/VR functionality into detachable modules, users with prescription glasses can attach the modules to their existing prescription frames rather than requiring separate dedicated AR/VR glasses. This eliminates the need for duplicative vision wear while maintaining full AR/VR functionality.
3Reliability
If specially designed headsets or glasses are used for augmented or virtual reality, then the system can provide AR/VR functionality, but third parties are restricted from introducing accessories that may improve on individual features or provide entirely new functionality
Solution Approach 1:
The modular architecture allows third-party developers to create and attach custom modules with specialized sensors or displays to the standardized frame. This enables continuous improvement of individual features and addition of entirely new functionalities without compromising the core AR/VR system's reliability.
Solution Approach 2:
The standardized attachment interface and common communication protocol allow modules from different manufacturers to work together with the core system. This universal compatibility enables third-party accessories to integrate seamlessly, providing enhanced or new functionality while maintaining system-wide reliability.
4Measurement precision
If current approaches are used for vision tracking, then the system can perform medical tests to determine overall fitness level, but the tests are performed separately in environments different from actual work environment, providing inaccurate results
Solution Approach 1:
The system continuously collects vision performance data in the natural work environment before formal medical tests are conducted. This preliminary data collection establishes a baseline that improves the accuracy of subsequent medical assessments by providing context-specific reference measurements.
Solution Approach 2:
The modular sensors continuously monitor vision parameters throughout the workday rather than performing discrete separate tests. This continuous measurement captures real-world vision performance under actual working conditions, providing more accurate and representative data for fitness assessment.

AI summary
Methods and systems for tracking vision performance use various techniques such as and not limited to electrooculography. A modular device is integrated with frames of eyeglasses that can be worn by a user. The device incorporates one or more biosensors such as EOG sensors. EOG recording may be used to estimate eyelid and eye motion, and eye gaze direction. The modular device may be fitted into new eyewear or retrofitted into existing eyewear for tracking eyes of the wearer. Systems and methods enable seamless integration of eye tracking into everyday life to maximize productivity and performance.
