Solution Overview

Problem

Current anti-acne treatments face challenges due to the rapid diffusion of topical agents away from acne lesions, leading to reduced efficacy as they diffuse out quickly from the treatment area.

Innovation Solution

The use of a vasoconstricting agent is applied prior to an anti-acne agent to reduce outflow, maintaining a higher concentration of the anti-acne agent at the lesion site, thereby enhancing treatment efficacy and reducing redness and swelling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a topical anti-acne agent is applied to the skin, then the agent can treat acne lesions, but the agent diffuses rapidly away from the lesion site reducing its efficacy

Engineering Contradiction:
Improveanti-acne treatment efficacyVSAvoidanti-acne agent diffusion away from lesion
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

A vasoconstricting agent is used as an intermediary substance applied before the anti-acne agent. This vasoconstrictor constricts blood vessels in the skin, creating a temporary barrier that reduces the diffusion and outflow of the anti-acne agent from the treatment area, thereby maintaining higher local concentrations of the active ingredient at the lesion site

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The vasoconstricting agent is applied in advance before the anti-acne agent to prepare the skin environment. By pre-constricting the blood vessels, the subsequent anti-acne agent is retained longer at the treatment site, enhancing its effectiveness without requiring higher doses

Inventive Principle:
Principle #10Preliminary action

2Quantity of substance

If a vasoconstricting agent is applied prior to anti-acne agent, then the outflow of anti-acne agent is reduced and local concentration is increased, but the treatment protocol becomes more complex

Engineering Contradiction:
Improvelocal concentration of anti-acne agentVSAvoidtreatment protocol complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The vasoconstricting agent is applied in advance before the anti-acne agent to prepare the skin environment. By pre-constricting the blood vessels, the subsequent anti-acne agent is retained longer at the treatment site, enhancing its effectiveness without requiring higher doses

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent combines two separate functional agents (vasoconstrictor and anti-acne agent) into a coordinated treatment sequence. While this increases protocol steps, the vasoconstrictor serves dual purposes: constricting vessels to retain the anti-acne agent and simultaneously reducing redness and swelling of the lesion

Inventive Principle:
Principle #5Merging (Combining)

3Duration of action of moving object

If topical anti-acne agents are used, then acne lesions can be treated, but the agents diffuse quickly reducing their dwell time in the dermis

Engineering Contradiction:
Improvedermal dwell time of anti-acne agentVSAvoiddiffusion speed of anti-acne agent
Core Design Contradiction:
Duration of action of moving objectVSSpeed

Solution Approach 1:

A vasoconstricting agent is used as an intermediary substance applied before the anti-acne agent. This vasoconstrictor constricts blood vessels in the skin, creating a temporary barrier that reduces the diffusion and outflow of the anti-acne agent from the treatment area, thereby maintaining higher local concentrations of the active ingredient at the lesion site

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The vasoconstricting agent changes the physiological parameters of the skin by constricting blood vessels, which reduces blood flow and creates a more favorable environment for retaining the anti-acne agent. This parameter change (reduced blood flow) directly extends the dwell time of the anti-acne agent in the dermis

Inventive Principle:
Principle #35Parameter changes
