Tattooing Apparatus Non-Linear Needle Motion for Ink Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tattooing apparatuses face issues with tattoo longevity due to the breakdown of larger pigment particles into smaller ones, leading to fading over time, as they are more prone to physical and chemical damage and decomposition from electromagnetic radiation.
Innovation Solution
The apparatus employs a non-linear reciprocating motion of the needle bar, facilitated by a pivot pin and angled needle arrangement, to widen skin piercings and deliver larger quantities of ink pigment particles, ensuring greater color vibrancy and longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional linear reciprocating motion is used, then the tattooing apparatus can deliver ink pigment particles, but the skin piercings are too narrow for optimal deposition of larger pigment particles
Solution Approach 1:
The needle bar is modified to enable dynamic non-linear reciprocating motion that widens the skin piercing path during ink deposition, allowing larger pigment particles to be deposited more effectively while maintaining control over the needle's movement through the pivot pin mechanism
Solution Approach 2:
The invention introduces a rotational dimension to the traditional linear reciprocating motion by using a pivot pin that allows the needle bar to rotate slightly during its reciprocating motion, creating an elliptical or widened piercing path that increases the surface area for pigment deposition
2Duration of action of stationary object
If larger ink pigment particles are used, then tattoo longevity is improved, but the particles are more prone to physical and chemical damage and decomposition
Solution Approach 1:
The invention changes the motion parameters of the needle bar from simple linear reciprocation to non-linear reciprocating motion with controlled rotation, which distributes the mechanical stress on large pigment particles more evenly and reduces the risk of particle breakage during injection
3Device complexity
If the needle bar uses simple linear reciprocating motion, then the device structure is simple, but it cannot widen skin piercings for optimal pigment deposition
Solution Approach 1:
A pivot pin is introduced as an intermediary element between the needle bar and the ink reservoir, enabling non-linear reciprocating motion without requiring a completely complex motion control system, thus achieving enhanced pigment delivery with moderate structural complexity

AI summary
A tattooing apparatus includes a grip body and a pivot pin. The grip body defines a cavity extending entirely through the grip body in a first direction. The pivot pin is mounted in the cavity perpendicular to the first direction, the pivot pin having an axis of rotation, the pivot pin mounted rotatably around the axis of rotation.A tattoo needle assembly includes a needle bar, a loop, and a plurality of needles. The needle bar has a first end and a second end. The loop is coupled to the first end and defines a first plane. The plurality of needles includes a first row coupled to the second end and defining a second plane, the first plane angled approximately 90 degrees to the second plane.A tattoo needle assembly includes three rows of at least three needles, the needles fastened together to be immovable with respect to each other.
