Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual tattooing is performed, then flexibility and adaptability are maintained, but precision, speed, and consistency deteriorate
Solution Approach 1:
The patent replaces the manual mechanical tattooing system with an automated robotic system that uses computer-controlled mechanisms for needle positioning, vibration control, and pigment delivery. The robotic arm with six degrees of freedom provides precise control while eliminating manual operation inconsistencies.
Solution Approach 2:
The system dynamically adjusts multiple parameters including needle vibration frequency (50-3,000 times per minute), penetration depth, pigment flow rate, and needle speed based on real-time feedback from image acquisition devices and pre-programmed design specifications.
2Productivity
If manual tattooing is performed, then operator control is maintained, but time consumption and labor intensity increase
Solution Approach 1:
The robotic system performs continuous tattooing operations without the interruptions typical of manual processes. The automated needle vibration and pigment delivery systems operate continuously at optimal speeds, eliminating pauses for repositioning or adjustment that occur in manual tattooing.
Solution Approach 2:
The system performs preliminary actions including digital design creation, path planning, and parameter optimization before the actual tattooing begins. Image acquisition devices capture the body surface topology in advance, allowing the robotic system to pre-calculate optimal needle paths and adjust for skin contours before contact is made.
3Reliability
If conventional tattoo removal is performed, then existing techniques are used, but multiple sessions and labor are required
Solution Approach 1:
The robotic removal system employs periodic laser pulses or mechanical abrasion cycles that are precisely timed and repeated. The system applies removal energy in controlled periodic intervals, allowing for cumulative effect while managing heat buildup and tissue response, thereby achieving complete removal in fewer sessions.
4Manufacturing precision
If precise pigment depth control is implemented, then tattoo quality improves, but system complexity increases
Solution Approach 1:
The system incorporates real-time feedback from image acquisition devices that monitor pigment delivery and skin response. Sensors detect variations in skin topology, pigment absorption, and needle position, continuously adjusting parameters to maintain optimal penetration depth and pigment placement throughout the tattooing process.
