Tattoo Ink Bottle Cap With Hinged Lid and Dual Seal

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing tattoo ink bottles lack a secure closure seal to prevent contamination and are difficult to open one-handed, posing challenges for tattoo artists during the time-consuming and delicate tattooing process.

Innovation Solution

A cap design featuring a base, a hinge, and a lid with diametrically-opposed operative regions allows for one-handed operation, providing a secure closure seal through inner and outer sealing parts that engage the nozzle rim.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a secure closure seal is implemented, then contamination prevention is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveclosure seal securityVSAvoidone-handed opening

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The cap is divided into a base and a lid as separate operable components, allowing the lid to be independently opened and closed while maintaining a secure seal when closed. This segmentation enables the seal to remain intact during storage and transport while allowing easy access during use.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The hinge mechanism transforms the static cap into a dynamic structure that can transition between closed (sealed) and open states. The hinge allows the lid to pivot smoothly, providing controlled movement that maintains seal integrity when closed while enabling easy one-handed operation when opening.

Inventive Principle:

Principle #15Dynamics

2Reliability

If a secure closure seal is implemented, then contamination prevention is improved, but device complexity increases

Engineering Contradiction:

Improveclosure seal securityVSAvoidcap structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The sealing function and the opening/closing mechanism are merged into a single integrated cap structure. The inner and outer sealing parts are incorporated directly into the base and lid components, eliminating the need for separate sealing mechanisms and reducing overall device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The inner and outer sealing parts function as flexible sealing elements that conform to the nozzle rim. These thin film-like sealing components provide effective contamination prevention while adding minimal structural complexity to the cap design.

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of operation

If one-handed operation is enabled, then ease of operation is improved, but closure seal security deteriorates

Engineering Contradiction:

Improveone-handed openingVSAvoidclosure seal security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The cap structure is designed to be self-contained, with the hinge and sealing parts working together to automatically maintain seal integrity. The user simply needs to press the operative region to open or close the lid, and the hinge mechanism automatically ensures proper sealing without requiring additional actions or tools.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The pressing depth of the operative region changes the state of the lid from closed to open. This parameter change (pressing depth) controls the opening action while the hinge mechanism ensures that when the lid returns to its closed position, the sealing parts engage properly to maintain seal security.

Inventive Principle:
