Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handheld devices are used to apply skin treatment compositions, then portability and ease of operation are improved, but speed and accuracy of defect detection and treatment are insufficient
Solution Approach 1:
The device segments the skin treatment process into distinct functional modules: sensor array for defect detection, CPU for image processing and analysis, and applicator nozzles for targeted composition delivery. This segmentation allows each component to operate independently and efficiently, resolving the contradiction between portability and processing speed by enabling parallel operations across separate functional units.
Solution Approach 2:
The sensor captures skin images and the CPU processes defect identification before the applicator delivers treatment composition. This preliminary detection and analysis action ensures that treatment is applied only to identified defects, improving both speed (by avoiding unnecessary treatment areas) and accuracy (by pre-identifying target locations) while maintaining portable operation.
2Ease of operation
If handheld devices move across the skin to treat defects, then ease of operation is improved, but accuracy of treatment application deteriorates because the user moves the applicator before the spot can be effectively treated
Solution Approach 1:
The device incorporates real-time feedback through continuous skin scanning and defect detection. The sensor continuously monitors skin surface, the CPU analyzes defect locations in real-time, and the applicator responds immediately by applying composition only to detected defects. This closed-loop feedback system eliminates the precision problem by ensuring treatment is applied at the exact moment and location of defect detection, while the handheld design maintains ease of operation.
Solution Approach 2:
The invention replaces manual mechanical control of treatment application with an automated system. Instead of relying on user skill to position and apply treatment, the CPU-controlled applicator automatically delivers composition to precisely located defects based on sensor data. This substitution of mechanical user control with automated electronic control resolves the contradiction between handheld ease of operation and treatment precision.
3Device complexity
If traditional skin treatment devices are used, then device complexity is reduced, but wireless communication capabilities and data processing efficiency are insufficient
Solution Approach 1:
The device integrates multiple functions into a single portable unit: skin imaging, defect analysis, treatment composition storage, and controlled application. The CPU serves multiple purposes including image processing, defect identification, and applicator control. This multi-functionality approach maintains relatively simple device structure while achieving high data processing speed and wireless communication capability through efficient use of integrated components.
Solution Approach 2:
The invention changes key operational parameters including image processing speed, defect detection sensitivity, and composition application timing. The CPU processes images at high speed to identify defects, and the system adjusts treatment parameters based on real-time analysis. These parameter changes enable rapid data processing and efficient wireless communication without significantly increasing overall device complexity, as the changes optimize existing component performance rather than adding substantial new hardware.

AI summary
A device for analyzing and treating tonal imperfections on human skin. The device, or apparatus has an applicator comprising a head and one or more nozzles, preferably the nozzles are arranged in an array. The apparatus further has a reservoir comprising a skin treatment composition, a sensor, and a CPU. The sensor takes an image of at least 10 μm2 of skin. The CPU analyzes the image to calculate a localized L value of individual pixels or group of pixels. The CPU then compares the local L value to a background L value to identify one or more skin deviations, and wherein the sensor is in wireless communication with the CPU, and wherein the CPU is adjacent the sensor or is remotely located. Further, the sensor may be enclosed within an apparatus handle and the CPU is either within the handle or external to the handle. In another embodiment of this invention, there are two or more CPUs and the sensor can be in wireless communication with none, one or more than one CPU.
