Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional DC power supply provides only stable voltage, then the power supply structure is simple, but it cannot be used in non-mechanical tattoo machines and results in limited applications
Solution Approach 1:
The power supply is designed to provide multiple output modes (square wave and direct current) to accommodate both non-mechanical and mechanical tattoo machines. The control unit switches between these modes based on the machine type, making the power supply universally applicable to different tattoo machine types while maintaining a relatively compact structure.
2Reliability
If a power supply provides only stable voltage, then the power supply is easy to operate, but it cannot provide adequate penetration for varying skin types resulting in inconsistent tattoo effects
Solution Approach 1:
The power supply transitions from providing only stable voltage to providing dynamically adjustable square wave parameters including frequency, duty cycle, and voltage. The control unit allows adjustment of these parameters to match different skin types and tattoo requirements, ensuring consistent tattoo effects while maintaining user-friendly operation through a microprocessor-controlled interface.
3Manufacturing precision
If a power supply provides only stable voltage, then the device complexity is low, but it results in needle penetration issues for both stiff and soft skin types
Solution Approach 1:
The power supply utilizes square wave parameters (frequency, duty cycle, voltage) that can be precisely adjusted to control needle penetration depth and speed. By changing these electrical parameters, the system achieves precise control over needle behavior during tattooing, accommodating both stiff and soft skin types while managing device complexity through integrated control circuitry.
