Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional scar treatment agents, such as silicone-based products, fail to effectively conceal scars while treating them, leading to aesthetic and functional issues, and there is a need for a formulation that can cover scars without toxicity.

Innovation Solution

A skin external composition combining pigment and silicone oil, where the pigment is dispersed in the silicone oil using a milling process to create a stable formulation that can be applied to the skin, concealing and treating scars without compromising normal wound healing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If silicone-based scar treatment agents are used, then scar treatment effectiveness is improved, but aesthetic appearance is worsened due to transparency and inability to conceal scars

Engineering Contradiction:

Improvescar treatment effectivenessVSAvoidaesthetic appearance

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies color changes by incorporating pigments into the silicone-based scar treatment agent. The composition includes pigments that provide color to the transparent silicone, enabling it to match skin tones or provide concealing coverage. This resolves the contradiction by maintaining the therapeutic effectiveness of silicone while adding aesthetic benefits through coloration that can conceal scars.

Inventive Principle:

Principle #32Color changes

2Ease of manufacture

If additional concealing sheets are attached after applying silicone scar treatment agent, then aesthetic appearance is improved, but device complexity and user inconvenience increase

Engineering Contradiction:

Improveaesthetic appearanceVSAvoidadditional concealing sheets

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the concealing function with the treatment function by incorporating pigments directly into the silicone scar treatment agent formulation. This combines what were previously separate products (transparent silicone gel and separate concealing sheets) into a single integrated product that both treats and conceals scars, eliminating the need for additional layers and simplifying the application process.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If pigment materials are added to conceal scars, then aesthetic appearance is improved, but toxicity risks increase

Engineering Contradiction:

Improveaesthetic appearanceVSAvoidtoxicity

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by carefully selecting and controlling the concentration, type, and properties of pigments used in the composition. The formulation specifies particular pigment materials and their concentrations to ensure safety while achieving desired aesthetic effects. This resolves the toxicity concern by modifying the parameters of pigment selection and dosage to remain within safe ranges for skin application.

Inventive Principle:

Principle #35Parameter changes

4Reliability

If stable formulation with pigment and silicone oil is created, then scar hiding ability and treatment effectiveness are improved, but manufacturing process complexity increases

Engineering Contradiction:

Improvescar hiding ability and treatment effectivenessVSAvoidmanufacturing process complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies segmentation by dividing the manufacturing process into distinct phases: first preparing the silicone oil base, then separately preparing the pigment dispersion, and finally combining them. This segmented approach to formulation development allows for better control of each component and facilitates the creation of a stable final product while managing manufacturing complexity through systematic process organization.

Inventive Principle:

Principle #1Segmentation
