Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a formulated fluid is sprayed at controlled pressure and flow rate, then penetration through the stratum corneum is enhanced, but the device complexity increases due to need for precise pressure control and flow rate regulation
Solution Approach 1:
The patent applies parameter changes by controlling pressure, spray pattern, and flow rate to optimize penetration through the stratum corneum. The system adjusts these parameters to enhance delivery of beneficial substances while managing the complexity through electronic control systems that regulate multiple parameters simultaneously.
2Manufacturing precision
If spray parameters are adjusted to optimize delivery to specific skin regions, then application precision is improved, but the ease of operation decreases due to multiple adjustment parameters
Solution Approach 1:
The patent employs dynamics by making the spray parameters adjustable and adaptable to different application needs. The system allows dynamic adjustment of pressure, spray pattern, and flow rate to optimize delivery to specific skin regions, enabling the device to adapt to various skincare requirements while maintaining user-friendly operation through electronic control.
3Reliability
If disposable formulation capsules are used to ensure sterility and convenience, then reliability of sterile application is improved, but loss of substance increases due to single-use format
Solution Approach 1:
The patent utilizes disposable formulation capsules to ensure sterility and convenience in home use. The capsules are pre-filled with cosmetic formulations and can be easily replaced, eliminating the need for complex cleaning and sterilization procedures. This disposable approach prioritizes sterility and user convenience while the system is designed to minimize formulation waste through precise delivery control.

Data Source
AI summary
A system and method for dermal spraying includes a portable, hand-held dermal application device with disposable formulation capsules that spray a formulation unto the skin and a data transmission unit operatively connecting the dermal spray device to a mobile device. The mobile device communicates with a remote server and transmits anonymized data about the user's skin conditions and treatment history. The anonymized data may be labelled and classified by a dermatologist, and stored on a secure cloud server. The anonymized data is used to train models for serum and treatment plan recommenders.
