Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual or visual assessment by experts is used to determine individual-specific data, then the method is simple to implement, but the precision and accuracy of product recommendations deteriorate
Solution Approach 1:
The patent replaces manual visual assessment by experts with an automated optical system using a camera to capture images of physical elements. The calculator processes these images to automatically determine individual-specific data, substituting human mechanical assessment with automated optical-mechanical-electronic systems to improve precision while maintaining ease of operation.
Solution Approach 2:
The patent introduces physical elements with distinctive sensory properties as intermediaries between the user and the data collection system. Users interact with these tangible elements rather than directly providing data, and the system captures images of selected elements to extract individual-specific characteristics, improving measurement precision through this intermediary mechanism.
2Ease of operation
If a questionnaire is used to collect user data, then the method is easy to administer, but the precision and reliability of determined data deteriorate
Solution Approach 1:
The patent replaces questionnaire-based data collection with an automated image capture and processing system. A camera captures images of physical elements selected by the user, and a calculator automatically processes these images to determine reliable individual-specific data, eliminating the unreliability of self-reported questionnaire data while maintaining ease of administration.
Solution Approach 2:
The patent uses physical elements that visually represent or copy actual individual characteristics (such as hair color swatches or skin tone samples). Users select physical elements that match their characteristics, and the system captures images of these selected elements to accurately determine individual-specific data, providing more reliable measurements than questionnaires.
3Measurement precision
If physical elements with sensory properties are used for selection, then the precision of determining individual-specific data improves, but the device complexity increases
Solution Approach 1:
The patent uses physical elements that are simple visual or tactile copies of actual characteristics (hair color swatches, skin tone samples). These elements have distinctive sensory properties that users can easily perceive and select. The system captures images of selected elements and processes them to determine individual-specific data with high precision, while the physical elements themselves remain simple and intuitive rather than complex.
Solution Approach 2:
The patent introduces physical elements as intermediaries that bridge the gap between simple user interaction and precise data determination. Users interact with simple tangible elements having distinctive sensory properties, while the backend system uses image capture and processing to extract precise individual-specific data. This intermediary approach maintains simplicity at the user interface while achieving high precision in data determination.
4Measurement precision
If automated image capture and processing is used instead of manual assessment, then the precision of data determination improves, but the device complexity increases
Solution Approach 1:
The patent replaces manual visual assessment with an automated system comprising a camera for image capture and a calculator for image processing. This mechanical-optical-electronic substitution enables precise automatic determination of individual-specific data from images of selected physical elements, improving precision while the automation reduces the need for complex manual procedures.
Solution Approach 2:
The patent implements an automated system where the camera automatically captures images and the calculator automatically processes them to determine individual-specific data without requiring manual intervention for data extraction. The system serves itself by automatically completing the determination process, improving precision while reducing operational complexity despite the presence of automated equipment.
