Two-Sided Multi-Cupped Fluid Holder for Tattoo Ink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tattoo ink holders lack a design with two sides and two volumes, which limits their functionality and efficiency in holding and organizing different ink colors for tattoo artists.
Innovation Solution
A two-sided, multi-cupped fluid holder with hexagonally shaped recesses and interlocking ridges and grooves, allowing for the creation of a 'honeycomb-like' configuration that enables easy organization and stacking of tattoo ink cups, preventing contamination and facilitating efficient use during the tattoo process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional single-sided ink holder is used, then the device structure is simple, but the functionality and organization efficiency are limited
Solution Approach 1:
The ink holder is divided into two distinct sides (first side and second side) with separate cup arrays, allowing independent organization of ink colors. Each side functions as an independent storage system, doubling the functional capacity without creating a single complex monolithic structure.
Solution Approach 2:
The design transitions from a single-sided planar structure to a two-sided three-dimensional structure. By utilizing both sides of the holder body, the design effectively doubles the storage capacity and organizational functionality while maintaining a compact form factor.
2Reliability
If multiple ink cups are organized in a single array, then the device structure is simple, but the risk of mixing and contamination increases
Solution Approach 1:
Ink cups are segregated into two separate arrays located on opposite sides of the holder. This physical segmentation prevents accidental mixing between different ink colors and reduces contamination risk, as each side operates as an independent storage zone.
Solution Approach 2:
The holder body acts as an intermediary barrier between the two ink cup arrays. The structural separation provided by the holder prevents direct contact between inks from different sides, eliminating the need for additional protective measures while maintaining reliability.
3Stability of the object's composition
If ink cups are stacked loosely, then the device is easy to assemble, but the stability and organization efficiency decrease
Solution Approach 1:
The cup recesses are designed with asymmetric positioning relative to the holder body, creating a specific geometric arrangement. When multiple holders are stacked, the asymmetric features align in a complementary manner, providing stable interlocking while maintaining ease of assembly through intuitive alignment.
Solution Approach 2:
The stacked configuration of multiple holders creates a self-stabilizing structure where the weight and geometry of upper holders naturally align with the recesses of lower holders. This self-aligning mechanism ensures stable stacking without requiring precise manual positioning or complex fastening mechanisms.
