Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specially designed headsets or glasses are used for augmented reality or virtual reality, then augmented reality or virtual reality functionality is achieved, but compatibility with prescription eyewear is restricted and special hardware investment is required
Solution Approach 1:
The system divides the augmented reality functionality into separate modular components that can be independently attached to conventional eyeglasses. Each module (display, sensor, processor) is a self-contained unit that can be selectively combined, allowing prescription eyewear users to add AR capabilities without replacing their entire glasses system.
Solution Approach 2:
The modular modules are designed to be universally compatible with various types of eyeglasses and can serve multiple functions. The same module can be attached to different prescription glasses, and the system can perform multiple tasks including display, sensing, and processing through integrated components.
2Adaptability or versatility
If integrated solutions are used for augmented reality headsets, then complete functionality is achieved, but flexibility for third-party accessories is restricted
Solution Approach 1:
The system separates the augmented reality functionality into independent modular components rather than using a monolithic integrated design. This segmentation allows third parties to develop and attach their own specialized modules to the base eyeglasses system, enabling accessory compatibility while maintaining complete functionality through module combinations.
3Reliability
If conventional eyeglasses are used without modular attachments, then simplicity and ease of use are maintained, but vision tracking and physiological data capture capabilities are absent
Solution Approach 1:
The system segments vision tracking and physiological data capture into separate sensor modules that can be independently optimized and attached to conventional eyeglasses. This allows high-accuracy specialized sensors to be integrated without requiring complete system redesign, maintaining simplicity while enhancing measurement capabilities.
Solution Approach 2:
The modular modules serve as intermediaries between the conventional eyeglasses and the vision tracking/physiological data capture functions. These modules provide the necessary sensing and processing capabilities while interfacing with the simple eyeglass structure, enabling advanced functionality without increasing base system complexity.
4Measurement precision
If medical tests are performed in separate environments different from actual work environment, then controlled testing conditions are achieved, but accuracy of results in real scenarios is reduced
Solution Approach 1:
The modular sensor modules are designed to function universally across different environments by capturing multiple physiological parameters (eye movements, brain signals, muscle signals, nerve signals) simultaneously. This multi-functional approach allows the system to adapt to various real-world conditions while maintaining measurement precision through comprehensive data collection.

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.
