Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a roller ball applicator is used to apply skin formula, then the formula can be applied to the skin surface, but the application may be inconsistent and non-uniform
Solution Approach 1:
The patent replaces manual mechanical application with an automated robotic arm system that precisely controls the roller ball's movement. The robotic arm uses sensors and control algorithms to maintain consistent pressure, speed, and trajectory, eliminating the variability inherent in manual application while requiring minimal user input beyond initial setup.
Solution Approach 2:
The system incorporates sensors that automatically detect skin type, formula viscosity, and application area characteristics, then self-adjust application parameters without user intervention. The robotic arm autonomously navigates the application area, adjusts pressure in real-time based on skin feedback, and maintains optimal rolling speed, making the system self-regulating during operation.
2Reliability
If light therapy is administered alongside formula application, then treatment efficacy is enhanced, but the device complexity increases
Solution Approach 1:
The patent integrates the light therapy module directly into the roller ball applicator head, merging two treatment functions (formula application and light therapy) into a single unified device. The light LEDs are positioned around the roller ball contact point, ensuring simultaneous delivery of both treatments at the exact same skin location, thereby enhancing efficacy while managing complexity through functional integration.
Solution Approach 2:
The robotic arm system is designed as a universal platform capable of performing multiple functions: applying different types of skin formulas, administering various wavelengths of light therapy, and adapting to different skin types and conditions. The system can be reconfigured for different treatments by changing the formula reservoir and light wavelength filters, making it a multi-functional device that handles diverse therapeutic needs.
3Adaptability or versatility
If AI-powered skin analysis is implemented, then personalized treatment recommendations can be provided, but the loss of time for data processing increases
Solution Approach 1:
The system performs preliminary skin analysis using cameras and sensors before treatment begins, capturing skin type, condition, and characteristics in advance. This preliminary data is processed to pre-determine optimal formula selection, light wavelength, and application parameters, so that during the actual treatment phase, no additional analysis time is needed—the system simply executes the pre-planned personalized protocol.
Solution Approach 2:
The system incorporates real-time feedback mechanisms where sensors monitor skin response during treatment and continuously adjust parameters. The AI analyzes this live feedback to refine the personalized treatment plan on-the-fly, learning from the actual skin reaction and adapting the formula application rate, light intensity, and wavelength dynamically, thereby personalizing treatment without adding significant time overhead.
