Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If retinal microperimetry is used to assess macular function, then the assessment provides detailed sensitivity mapping, but the procedure is time-consuming and lacks digital automation
Solution Approach 1:
The patent replaces the manual, mechanical retinal microperimetry system with an automated digital visor system that uses optical detection and software processing to assess macular function. The visor presents visual targets and automatically tracks eye movements and responses, eliminating the need for manual observation and calculation while maintaining measurement precision.
Solution Approach 2:
The patent changes the assessment parameters from detailed sensitivity mapping to a simplified macular function percentage coefficient. This parameter transformation allows rapid calculation and comparison of macular function while significantly reducing test execution time and improving productivity.
2Reliability
If traditional assessment methods are used, then environmental factors can be observed, but the results are subject to interference and lack reliability
Solution Approach 1:
The patent extracts the assessment from the external environment by creating a controlled virtual reality environment within the visor. This isolation eliminates environmental interference factors while maintaining assessment reliability through standardized virtual stimuli and automated detection algorithms.
3Productivity
If a digital assessment system is developed, then rapid and automated results are achieved, but the system complexity increases
Solution Approach 1:
The patent creates a multi-functional visor system that combines virtual reality display, optical eye tracking, response detection, and automated calculation capabilities in a single device. This universal approach achieves rapid assessment through integration, where multiple functions work together to reduce overall system complexity despite the advanced capabilities.
