Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tattooing devices cause significant pain and poor hygiene due to the use of needles for injecting dye, and the quality of tattoos depends on the user's skill level.
Innovation Solution
A tip for injecting tattoo dye that uses a pressure chamber and laser beam to generate pressure, allowing the dye to be injected without a needle, featuring a membrane unit, dye chamber, and inject nozzle with valves to control dye flow and prevent external contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a needle is used to inject dye into the skin, then the dye can be injected into the skin, but the person feels considerable pain and hygiene is poor
Solution Approach 1:
The patent removes the needle component from the tattooing system entirely. Instead of using a needle to penetrate the skin, the invention uses a nozzle that sprays dye onto the skin surface, extracting the harmful piercing element while preserving the core function of dye application.
Solution Approach 2:
The patent replaces the mechanical needle-penetration system with a fluid dynamics-based spray system. High-pressure liquid propulsion propels dye through a nozzle in a controlled spray pattern, substituting mechanical intrusion with fluid projection to achieve painless application.
2Manufacturing precision
If a needle is used for tattooing, then dye injection is achieved, but tattoo results vary according to user skill level
Solution Approach 1:
The patent controls spray parameters (pressure, flow rate, nozzle geometry) to standardize dye application. By adjusting and fixing these parameters, the system achieves consistent tattoo results independent of operator skill, as the spray characteristics remain constant during operation.
Solution Approach 2:
The high-pressure liquid propulsion system automatically regulates dye flow and pressure without requiring manual control by the operator. The system self-regulates the injection process through its internal pressure mechanisms, eliminating variability introduced by human operation.
3Reliability
If valves are added to control dye flow, then dye flow control and contamination prevention are improved, but device complexity increases
Solution Approach 1:
The patent designs valves that perform multiple functions: controlling dye flow during injection and preventing contamination by sealing the system. The same valve structure serves both flow regulation and hygiene protection, reducing the need for separate components.
Solution Approach 2:
The patent integrates valves within the existing chamber structure, nesting the flow control mechanism inside the dye reservoir or injection chamber. This nested arrangement allows valve functionality to be incorporated without significantly increasing external device dimensions or component count.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces pain during tattooing, ensures hygienic procedures, and allows for consistent, controlled dye injection, preventing external materials from entering the skin.
Implementation Method 1
a window provided at a first side of the pressure chamber, and configured to allow a laser beam emitted from an outside to pass therethrough and reach the liquid accommodated in the pressure chamber
Implementation Method 2
configured to be increased in pressure by laser pulses applied thereto from the outside
Implementation Method 3
a membrane unit provided at the first side of the pressure chamber, and configured to seal the pressure chamber and be transformed by pressure generated as the liquid is irradiated with the laser beam
Implementation Method 4
the opening/closing portion may include an elastic material to be transformed by difference between the internal pressure of the dye chamber and the internal pressure of the channel
