Tattoo Needle Unit With Mixed Diameter Needles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tattoo needle units with needles of the same thickness and closely spaced arrangements struggle to accurately implement various and natural tattoo techniques, limiting the ability to create desired shapes.
Innovation Solution
A tattoo needle unit featuring a combination of first and second needles with different diameters, arranged in various configurations within a pocket, allowing for adjustable spacing and exposure of needle tips to facilitate diverse tattoo techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If needles of the same thickness are combined with closely spaced arrangement, then the structure is simple and easy to manufacture, but the ability to accurately implement various tattoo techniques and create natural shapes is limited
Solution Approach 1:
The patent applies local quality by varying the diameter of individual needles within the same needle unit. Instead of using uniform needles throughout, the invention incorporates needles with different diameters (first diameter and second diameter) at specific positions, allowing different parts of the needle unit to perform different functions - creating both fine details and bold strokes, thereby enhancing tattoo versatility while maintaining a relatively simple overall structure
2Area of stationary object
If needles are densely arranged with very close spacing, then the needle unit structure is compact, but it becomes difficult to accurately use various tattoo techniques and implement desired shapes
Solution Approach 1:
The patent applies parameter changes by modifying the spacing parameter between needles based on their positions and diameters. Instead of uniform dense spacing, the invention adjusts the distance between needles to create optimized patterns that accommodate different diameter needles, allowing for both compact overall dimensions and sufficient spacing where needed to achieve precise tattoo shapes and techniques
3Device complexity
If needles of the same thickness are used, then the needle unit structure is simple, but it is difficult to create diverse and natural tattoos with varying line weights and textures
Solution Approach 1:
The patent applies asymmetry by introducing needles with different diameters into the needle unit configuration. This asymmetric design, where some needles have a first diameter and others have a second diameter, enables the creation of diverse tattoo styles with varying line weights, textures, and effects, while the overall asymmetric arrangement remains within a manageable complexity framework

AI summary
Tattoo needle unit according to the present invention includes a pocket having a body part; at least one first needle having a first diameter and coupled to the pocket; and at least one second needle having a second diameter larger than the first diameter and coupled to the pocket, wherein, a part of the first needle is exposed out of the body part, and another part of the first needle is disposed inside the body part, and wherein, a part of the second needle is exposed out of the body part, and another part of the second needle is disposed inside the body part. According to the tattoo needle unit according to the present invention, there is an advantage in that it is possible to easily implement a tattoo of a more diverse and natural shape due to the combination of various types of needles.
