Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional visual assessment methods are used in professional settings, then measurement precision is maintained, but device complexity and accessibility are limited
Solution Approach 1:
The patent creates a virtual copy of the clinical vision testing environment using VR technology. The system replicates standardized visual assessment protocols and equipment functionality within a virtual reality framework, allowing home-based testing to achieve clinical-grade measurement precision without requiring physical presence in a medical office or specialized equipment
2Reliability
If traditional visual assessment methods are used, then standardized procedures are followed, but adaptability to dynamic test parameters is reduced
Solution Approach 1:
The VR system implements dynamic adaptability by allowing real-time modification of test parameters such as visual stimulus characteristics, environmental lighting conditions, and test progression rates. The system can dynamically adjust these parameters based on user performance and specific assessment needs while maintaining standardized evaluation protocols through programmed test sequences, thereby achieving both reliability and versatility
3Measurement precision
If traditional visual assessment methods are used in clinical environments, then controlled conditions are maintained, but ease of operation for home use is reduced
Solution Approach 1:
The VR vision testing system serves multiple functions: it provides clinical-grade vision assessment, creates controlled testing environments, guides users through standardized procedures, and enables both professional and home-based usage. This multi-functionality allows the same system to maintain measurement precision while being easily operable in diverse settings including patients' homes, thereby resolving the contradiction between accuracy and accessibility

AI summary
A virtual reality (VR) system can be implemented for real-time visual health monitoring during extended use. The system employs an electronic device featuring a head-mounted display (HMD) and eye-tracking sensors. It generates a VR user interface corresponding to a three-dimensional virtual environment and renders it on the VR headset. During extended VR sessions, the system continuously monitors the user's eye movements and behavior using the eye-tracking sensors. This data is analyzed to detect various visual health indicators. Based on these indicators, the system dynamically adjusts the VR user interface to optimize the visual experience and potentially mitigate negative effects on the user's visual health during prolonged VR use.
