Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional vision testing methods are used, then the testing can be conducted in controlled clinical environments with standardized procedures, but the testing is limited to professional settings and cannot be dynamically adjusted or performed at home

Engineering Contradiction:

Improveaccessibility and adaptability of vision testingVSAvoidcomplexity of testing equipment and environment

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a virtual copy of the clinical testing environment within a VR headset. The standardized vision testing procedures are replicated as virtual optotypes and test sequences that can be displayed on the HMD, allowing home users to experience the same controlled testing conditions without needing physical clinical equipment. This copying approach enables accessibility while maintaining testing standardization.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces physical mechanical testing equipment (optometers, vision charts, lighting controls) with a virtual reality system. The HMD displays virtual optotypes that substitute for physical eye charts, and the system's software controls substitute for manual lighting adjustments and equipment positioning. This substitution eliminates the need for complex physical equipment while maintaining controlled testing parameters.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If traditional vision testing methods are used, then the testing parameters are fixed and standardized, but the testing lacks dynamic adjustment capabilities leading to less accurate assessments

Engineering Contradiction:

Improveaccuracy of vision assessmentVSAvoiddynamic adjustment of test parameters

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic adjustment of vision testing parameters through software control of the VR environment. The system can dynamically modify optotype size, spacing, contrast, lighting conditions, and test sequence based on user responses and performance. This dynamic capability allows the system to adapt to individual user needs and optimize measurement precision for different vision conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent incorporates feedback mechanisms where the system monitors user responses to visual stimuli and adjusts testing parameters accordingly. Based on performance data, the system can modify subsequent test items to better assess specific vision deficiencies, creating an adaptive testing process that improves measurement accuracy through continuous feedback-driven parameter adjustment.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If traditional vision testing methods are used, then the testing can be performed with simple household devices, but the testing cannot be implemented in a consistent and environment-locked manner

Engineering Contradiction:

Improveease of home testingVSAvoidconsistency and reliability of testing results

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent creates a controlled virtual environment within the VR system that isolates the testing conditions from external environmental variables. The HMD displays standardized virtual optotypes with controlled lighting, contrast, and positioning that remain consistent regardless of actual physical environmental conditions. This virtual inert environment ensures reliable and repeatable testing results while maintaining ease of home operation.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

AI summary

A virtual reality (VR) system can be implemented for vision testing and eye health monitoring. The system utilizes an electronic device equipped with a high-resolution VR headset, eye-tracking sensors, and wearable devices capable of measuring intraocular pressure, tear film stability, and ocular blood flow. The device generates a VR user interface corresponding to a three-dimensional virtual environment and renders it on the VR headset. Within this environment, the system conducts a series of vision tests. Throughout these tests, the system continuously monitors eye movements using the eye-tracking sensors and collects vital data from the wearable devices. This data is then evaluated to assess both visual performance and overall eye health, providing a more holistic view of the user's ocular condition in a controlled virtual setting.
