Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional visual acuity charts are used, then vision test can be conducted, but professional guidance is required and real-time vision information cannot be obtained
Solution Approach 1:
The vision testing device enables users to perform vision tests independently without professional guidance. The device automatically controls light-emitting units to display test marks, captures user responses via camera, processes results, and provides real-time vision information, allowing individuals to serve their own vision testing needs.
Solution Approach 2:
The patent replaces the manual mechanical process of professional administration with an automated electronic system. The control unit automatically controls light-emitting units, captures images via camera, processes vision data, and displays results, substituting the mechanical interaction between tester and test subject with an automated information processing system.
2Measurement precision
If traditional visual acuity charts are used, then vision test can be conducted, but inaccuracy occurs due to light and distance variations
Solution Approach 1:
The device dynamically adjusts lighting parameters by controlling multiple light-emitting units with adjustable brightness and color temperature. The system compensates for environmental light variations and maintains optimal testing conditions, eliminating the harmful effect of light variations on measurement accuracy.
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit captures user responses via camera, processes the vision test data, and provides real-time results. This feedback loop allows the system to adjust and optimize testing parameters based on actual user performance, ensuring accurate measurement despite environmental variations.
3Reliability
If professional guidance is required for vision test, then test can be administered, but inconvenience is caused and real-time vision information cannot be obtained
Solution Approach 1:
The vision testing device enables users to perform vision tests independently without professional guidance. The device automatically controls light-emitting units to display test marks, captures user responses via camera, processes results, and provides real-time vision information, allowing individuals to serve their own vision testing needs.
