Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional micropigmentation techniques, such as tattooing, are painful, time-consuming, and prone to errors due to manual operation, and lack precision in applying multiple colors simultaneously, while also being limited in detail and causing trauma to the skin.
Innovation Solution
A raster injector with a disposable, interchangeable ink delivery assembly and a motion platform that uses an array of hollow point needles to precisely inject ink into the skin or other materials, allowing for simultaneous application of multiple colors and reduced trauma through controlled, reciprocating motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual or motorized puncturing devices are used for micropigmentation, then the procedure can be performed with simple equipment, but the process is time-consuming and prone to human error
Solution Approach 1:
The device segments the ink delivery system into multiple independent channels, each with its own needle and ink reservoir. This allows simultaneous application of multiple colors through separate controlled pathways, eliminating the sequential process of traditional tattooing and enabling parallel operation for increased productivity without sacrificing precision.
Solution Approach 2:
The patent replaces manual mechanical operation with an automated robotic system that controls needle insertion depth, speed, and positioning through programmable motion control. This substitution eliminates human error and enables precise application of multiple colors simultaneously while reducing procedural time through consistent, repeatable movements.
2Ease of operation
If traditional tattooing methods are used, then the equipment is simple and easy to operate, but the skin trauma is severe and pain is intense
Solution Approach 1:
The device employs dynamic control of needle insertion parameters including variable depth, speed, and reciprocating motion patterns. The robotic system adjusts these parameters in real-time based on skin feedback, optimizing the balance between effective pigment delivery and minimizing skin trauma, while maintaining ease of operation through automated control.
Solution Approach 2:
The patent implements periodic reciprocating motion of the needles, where each needle inserts and retracts in a controlled cycle. This periodic action allows ink deposition during insertion while retracting to minimize trauma and allow skin recovery between strokes, reducing overall pain and damage compared to continuous traditional tattooing methods.
3Device complexity
If traditional single-color application is used, then the equipment complexity is low, but the detail and quality of tattoo designs are limited
Solution Approach 1:
The ink delivery system is segmented into multiple independent channels, each capable of delivering a different color simultaneously. This segmentation enables complex multi-color designs with precise spatial control, where each color can be applied to specific areas without interfering with others, greatly enhancing design detail and quality while managing complexity through modular architecture.
Solution Approach 2:
The device applies different colors and ink concentrations to specific local areas through individually controlled needle channels. Each needle can be independently programmed to deposit pigment only where needed, enabling photo-realistic effects and fine detail work by varying local ink properties and application parameters across different regions of the design.
4Reliability
If repeated over-application of colors is used, then complete coverage is achieved, but the procedure causes severe pain and takes many hours
Solution Approach 1:
The patent merges multiple color application operations into a single simultaneous process. All color channels operate in parallel during one pass, depositing their respective pigments at the same time and location coordinates. This merging eliminates the need for repeated sequential passes over the same area, achieving complete multi-color coverage in one procedure and dramatically reducing both time and pain.
Solution Approach 2:
The robotic system maintains continuous motion and ink flow across all needle channels throughout the procedure. By eliminating stops and restarts between color applications, the system achieves complete coverage through uninterrupted simultaneous deposition of all colors, reducing total procedural time while maintaining reliable pigment placement and coverage.
