Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different instruments and professionals are used for optometric measurements, then measurement versatility and accessibility are improved, but measurement precision and reliability deteriorate due to variations in accuracy
Solution Approach 1:
The patent applies parameter changes by introducing evaluation criteria that assess measurement quality based on instrument parameters, professional qualifications, and measurement conditions. The system transforms raw measurement data into evaluated results with quality scores, allowing versatile measurement access while maintaining precision through systematic parameter evaluation and comparison against reference values.
2Adaptability or versatility
If multiple optometry devices and sites are used, then measurement coverage and adaptability are improved, but measurement reliability deteriorates due to lack of standardization
Solution Approach 1:
The patent implements equipotentiality by establishing a standardized evaluation framework that equalizes measurement conditions across different devices and sites. All measurements are processed through the same evaluation criteria, reference value comparisons, and quality assessment algorithms, creating uniform measurement potential regardless of the specific device or location used.
3Ease of operation
If optometric measurements are performed without standardized evaluation, then ease of operation is improved, but manufacturing precision of ophthalmic lenses deteriorates due to measurement errors
Solution Approach 1:
The patent applies feedback by providing evaluation results and quality scores back to the measurement process. The system compares measurements against reference values, identifies deviations, and provides feedback on measurement quality. This feedback loop enables operators to maintain simple measurement procedures while ensuring precision through systematic evaluation and corrective actions when quality thresholds are not met.
