Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual or tactile methods are used for skin diagnosis, then the method is simple and accessible, but the accuracy and reliability of diagnosis deteriorates
Solution Approach 1:
The patent combines multiple diagnostic functions (optical imaging, moisture sensing, elasticity measurement) into a single portable device that attaches to a smartphone. This integration allows the device to maintain simplicity of use while significantly improving diagnostic accuracy through objective measurements rather than subjective visual or tactile assessments.
Solution Approach 2:
The patent introduces an intermediary optical unit with lenses and light sources that captures skin images and transmits them to the smartphone for analysis. This intermediary system bridges the gap between simple portable operation and accurate diagnostic measurement by performing the complex imaging function separately from the user interface.
2Measurement precision
If specialized skin diagnostic equipment is used, then the accuracy of skin diagnosis improves, but the cost and accessibility deteriorates
Solution Approach 1:
The patent creates a universal diagnostic device that can attach to various smartphone models and performs multiple skin assessment functions (imaging, moisture measurement, elasticity testing). By utilizing the smartphone's existing processing power and display capabilities, the device avoids the need for expensive specialized equipment while maintaining diagnostic accuracy.
Solution Approach 2:
The patent creates a portable copy of specialized diagnostic functionality by integrating cameras, sensors, and processing capabilities into a smartphone-attached device. This allows professional-grade skin analysis to be replicated in a consumer-friendly format, dramatically reducing cost while maintaining measurement precision.
3Device complexity
If the optical unit is not precisely aligned with the image sensor, then the device structure becomes simpler, but the quality of captured skin images deteriorates
Solution Approach 1:
The patent implements self-aligning features where the optical unit automatically positions itself relative to the smartphone's image sensor through mechanical guides or magnetic alignment. This self-service alignment mechanism eliminates the need for complex manual adjustment systems while ensuring high-quality image capture for accurate skin diagnosis.
