Solution Overview

Problem

Current tattoo removal methods are difficult, costly, and painful, and existing techniques do not fully address the need for efficient and minimally invasive solutions for removing tattoos without causing significant scarring or skin sensitization.

Innovation Solution

The method employs patterned trans-epidermal pigment release (TEPR) using templates to outline treatment areas on the skin, delivering a tattoo removal fluid in a series of sessions, optimizing the size and shape of wounds to promote healing and minimize overlap, thereby reducing the number of treatment sessions and potential for scarring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional tattoo removal methods are used, then tattoo ink can be removed, but the process is difficult, costly, and painful with significant scarring and skin sensitization

Engineering Contradiction:

Improvetattoo removal effectivenessVSAvoidscarring and skin sensitization

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The treatment area is divided into multiple discrete tegulae (small treatment zones) arranged in a patterned grid. Each tegula is treated independently with localized fluid delivery through template apertures, segmenting the overall tattoo removal process into multiple small, controlled injury sites rather than treating the entire area uniformly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies different treatment qualities to different parts of the tattoo. Each tegula receives localized fluid delivery through specific aperture patterns, creating localized injuries that stimulate healing responses. The treatment intensity and fluid delivery are concentrated at specific tegula boundaries rather than distributed uniformly across the entire tattoo area.

Inventive Principle:

Principle #3Local quality

2Reliability

If multiple treatment sessions are used to remove tattoos, then more complete ink removal is achieved, but the number of sessions increases treatment time and cost

Engineering Contradiction:

Improveink removal completenessVSAvoidnumber of treatment sessions

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent uses templates with pre-defined aperture patterns to mark and outline tegulae before treatment. The grid pattern of tegulae is established in advance, and fluid delivery is pre-configured to target specific tegula boundaries. This preliminary structuring of the treatment area enables more efficient ink removal across multiple sessions by ensuring consistent, patterned coverage.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent employs a series of periodic treatment sessions where fluid is delivered to alternating or complementary sets of tegulae. This periodic application allows ink removal to progress systematically across the entire tattoo area over multiple sessions, with each session treating a specific subset of the patterned tegulae according to the pre-established grid.

Inventive Principle:

Principle #19Periodic action

3Productivity

If larger wound areas are treated to remove more ink per session, then fewer treatment sessions are needed, but scarring and skin damage increase

Engineering Contradiction:

Improveink removal rate per sessionVSAvoidskin damage and scarring

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies fluid delivery to only specific portions of the skin (tegulae boundaries) rather than treating the entire tattoo area in each session. By targeting only the perimeter regions of each tegula where fluid is delivered, the treatment achieves ink removal through localized healing responses without subjecting large areas of skin to excessive damage.

Inventive Principle:

Principle #16Partial or excessive action

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

This approach allows for efficient removal of tattoos with reduced scarring, minimal skin sensitization, and fewer treatment sessions, as it utilizes localized injuries to initiate a healing response that pushes tattoo ink out of the skin, promoting effective ink removal without extensive dermal disruption.

AI summary

Embodiments of a method for removing a tattoo through patterned trans-epidermal pigment release includes determining first treatment area of skin of a patient through a primary template including primary apertures, marking the first treatment area of skin of the patient along borders of the primary apertures to outline a grid of primary tegulae, and delivering a tattoo removal fluid to the marked first exposed skin. In an alternate embodiment, a template, which may be adhered to the skin, is used during a disruption process to create a structured, patterned procedure to remove skin irregularities. The template has a plurality of needle apertures, an adhesive layer, and a release liner. The release liner may be removed, exposing the adhesive layer, so that the template, with the plurality of needle apertures, may be positioned over the skin irregularity.
