Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional eye examination methods are used, then the diagnostic process is simple and non-invasive, but the accuracy and capability to detect early signs of ocular conditions is limited
Solution Approach 1:
The examination system is divided into multiple specialized modules, each targeting specific ocular conditions (e.g., macular degeneration detection module, glaucoma screening module, eye alignment assessment module). Each module uses targeted visual stimuli and analysis algorithms appropriate for its specific diagnostic purpose, allowing high precision for individual conditions while maintaining overall system manageability through modular architecture.
Solution Approach 2:
The VR examination system is designed as a multi-functional platform that can detect various ocular conditions through a single integrated system. The same VR headset and eye-tracking hardware support multiple diagnostic protocols and visual tests, eliminating the need for separate examination devices for each condition while maintaining specialized diagnostic capabilities.
2Reliability
If advanced VR technology with eye-tracking sensors is implemented, then the capability to detect early signs of ocular conditions is improved, but the device complexity and cost increase
Solution Approach 1:
The system uses virtual visual stimuli displayed through VR headsets as copies or representations of real-world visual patterns. These virtual patterns (e.g., virtual Amsler grids, virtual optotypes) serve as substitutes for physical examination tools, enabling repeated, precise measurements without wear and tear on physical equipment while maintaining diagnostic accuracy.
Solution Approach 2:
Traditional mechanical examination tools (such as handheld Amsler grids, Snellen charts, and manual eye alignment devices) are replaced with electronic VR displays and digital eye-tracking sensors. The mechanical measurement process is substituted with electronic signal capture and digital image analysis, improving reliability while reducing physical wear and enabling automated analysis.
3Adaptability or versatility
If multiple visual tests and analysis algorithms are conducted, then the comprehensive assessment of ocular health is improved, but the examination time and processing requirements increase
Solution Approach 1:
The examination system dynamically adapts the sequence and type of visual tests based on real-time patient responses and preliminary findings. If a patient shows signs of macular degeneration during initial testing, the system automatically progresses to more specialized macular assessment protocols. This dynamic adaptation ensures comprehensive assessment when needed while avoiding unnecessary tests that would extend examination time.
Solution Approach 2:
The system incorporates real-time feedback loops where analysis algorithms continuously monitor patient responses to visual stimuli and adjust subsequent testing parameters accordingly. Preliminary results from one visual test inform the design of follow-up tests, creating an iterative assessment process that efficiently identifies and focuses on the most relevant diagnostic procedures based on individual patient presentations.

AI summary
A patient's retinal health can be evaluated via a virtual reality (VR) system, which can include a VR headset in electronic communication with a computing device. The VR headset can scan the patient's retinas using sensors and cameras. The computing device can cause a first vision test to be displayed on the screens of the VR headset. Using varying combinations of sensors, cameras, probes, and microphones, the VR headset collects data about the patient as she responds to the first vision test. Optionally, the computing device can cause a second vision test to be displayed on the screens, where the second vision test can be constructed on the patient's responses to the first vision test.
