Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand application method is used, then ease of operation is improved, but manufacturing precision (application uniformity) deteriorates
Solution Approach 1:
The patent replaces manual hand application with an automated electrostatic spraying system that uses high-voltage electrical fields to atomize and deposit cosmetic substances. The spraying device incorporates a high-voltage electrode connected to a power supply, creating an electrostatic field that charges droplets for uniform deposition on the skin, eliminating the imprecision of manual application while maintaining ease of use through automated operation.
2Productivity
If conventional spraying devices are used, then productivity is improved, but loss of substance deteriorates
Solution Approach 1:
The patent incorporates sensors that detect the application process parameters and provide feedback to a control unit. The control unit adjusts the spraying parameters in real-time based on this feedback, optimizing the electrostatic field strength, droplet charge, and deposition rate to ensure complete transfer of cosmetic substance to the skin, thereby minimizing waste while maintaining high productivity.
Solution Approach 2:
The patent dynamically changes operational parameters including high-voltage electrode voltage, droplet size distribution, and spraying rate based on skin surface detection and application progress. These parameter adjustments ensure optimal adhesion and uniform distribution of the cosmetic substance, reducing overspray and substance loss while maintaining efficient application speed.
3Productivity
If conventional spraying devices are used, then productivity is improved, but manufacturing precision (dosage control) deteriorates
Solution Approach 1:
The control unit receives feedback from sensors monitoring the application process and adjusts the electrostatic field parameters and spraying rate in real-time to maintain precise dosage control. The system monitors the amount of substance applied and modifies the high-voltage electrode output to ensure consistent, correct dosing across different skin areas and application speeds, preventing both under-dosing and over-dosing while maintaining high productivity.
4Loss of substance
If electrostatic atomization is used, then loss of substance is improved, but device complexity deteriorates
Solution Approach 1:
The patent integrates multiple functions into a single compact device: the high-voltage electrode serves both as the atomization mechanism and the charging source for electrostatic deposition; the control unit combines sensor processing, parameter adjustment, and spray control functions; the system simultaneously achieves substance atomization, electrostatic charging, and controlled deposition. This multi-functionality reduces overall device complexity while minimizing substance loss.
