Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand application is used, then the application process is simple, but the distribution of cosmetic substance is uneven and time-consuming
Solution Approach 1:
The patent replaces manual hand application with an automated electrostatic spraying system that uses electrostatic forces to atomize and distribute cosmetic substances. The spraying device incorporates a high-voltage electrode to charge particles and a grounded target area on the skin, eliminating the need for manual rubbing and achieving uniform distribution automatically.
Solution Approach 2:
The patent changes the physical state and electrical properties of the cosmetic substance by charging particles with high voltage before application. This electrostatic charging transforms the substance from a neutral form that requires manual spreading into charged particles that are automatically attracted to and evenly distributed on the skin surface through electrostatic forces.
2Ease of operation
If pump sprays or pressurized aerosol containers are used, then contact with cosmetic substance is minimized, but a large part of the substance is lost to the surroundings
Solution Approach 1:
The patent replaces conventional pneumatic spray mechanisms with an electrostatic atomization system. Instead of using propellant pressure to force substance through a nozzle, the system uses electrostatic forces to charge and attract particles directly to the skin, ensuring nearly 100% deposition efficiency and eliminating waste to the surrounding environment.
Solution Approach 2:
The patent incorporates sensors that detect the presence and coverage of cosmetic substance on the skin in real-time. This feedback mechanism allows the system to monitor application progress and adjust spraying parameters accordingly, ensuring complete coverage while preventing over-spray and substance loss to the environment.
3Extent of automation
If conventional spraying devices with constant output quantity are used, then the application process is automated, but uneven distribution occurs when the container is moved unevenly or oriented incorrectly
Solution Approach 1:
The patent employs dynamic control of the electrostatic spraying system that adapts to the user's movement patterns. The system incorporates sensors to detect device orientation and movement, and automatically adjusts spraying parameters in real-time to maintain uniform distribution regardless of how the device is held or moved, making the application process both automated and precise.
Solution Approach 2:
The patent uses real-time feedback from sensors that monitor device orientation, position, and spray coverage. This feedback loop allows the control system to continuously adjust the electrostatic field strength and particle emission rate, ensuring even distribution even when the device is moved unevenly or at different angles during application.
4Manufacturing precision
If electrostatic spraying devices with high-voltage electrodes are used, then targeted application is achieved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single compact device: the electrostatic charging mechanism, particle atomization system, sensor array for detection, and control unit for processing signals are all combined in one handheld unit. This multi-functionality achieves targeted application precision while keeping the device portable and relatively simple to operate.
Solution Approach 2:
The patent incorporates sensors and processors that automatically detect skin type, measure UV exposure, and adjust spraying parameters without requiring user input or complex manual adjustments. The device performs self-diagnosis and self-adjustment, reducing the operational complexity for the user while maintaining high precision in targeted application.
