Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external hardware adapters or benchtop equipment are used to evaluate personal care compositions, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the infrared detection capability from complex external hardware and integrates it into a smartphone camera module, allowing the mobile device itself to detect personal care compositions without requiring external adapters or benchtop equipment
Solution Approach 2:
The smartphone camera is made multi-functional by enabling it to perform both standard photography and infrared radiation detection for personal care composition evaluation, eliminating the need for dedicated specialized equipment
2Device complexity
If infrared radiation detection is implemented using existing image capture devices, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent changes the operational parameters of the image capture device by adjusting it to detect infrared radiation wavelengths, enabling existing hardware to achieve detection capabilities previously requiring specialized equipment through parameter modification rather than hardware replacement
3Ease of operation
If traditional detection methods are used, then ease of operation is maintained, but loss of information increases due to inability to detect composition presence
Solution Approach 1:
The system provides real-time feedback to the user by detecting and displaying information about personal care composition presence and coverage, enabling users to make informed decisions about application sufficiency without requiring manual assessment or specialized knowledge
