Solution Overview

Problem

Existing patchable cosmetic products face issues such as foreign objects sticking during removal, folding during attachment, and inaccurate adhesion due to manual application, leading to incomplete distribution of pressure.

Innovation Solution

An applicator with a handle, supporting unit, and patch-attaching unit, featuring a coupling mechanism that allows for easy detachment from a release sheet and secure attachment to the skin, ensuring even pressure distribution and preventing lifting or folding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual attachment method is used, then device complexity is reduced, but manufacturing precision deteriorates due to inaccurate pressure distribution

Engineering Contradiction:
Improveattachment process complexityVSAvoidadhesion accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent introduces a specialized applicator as an intermediary tool between the user and the patchable cosmetic product. The applicator includes a pressing element with a pressing surface that contacts the patch, a handle for user operation, and a release sheet for easy patch attachment. This intermediary device enables accurate and uniform pressure distribution across the patch during attachment, solving the adhesion accuracy problem while maintaining operational simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If manual removal is performed, then ease of operation is improved, but object-affected harmful factors increase due to foreign objects sticking to the patch

Engineering Contradiction:
Improveremoval convenienceVSAvoidforeign object contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The applicator serves as a mediator during both attachment and removal processes. The pressing element maintains contact with the patch throughout the process, allowing controlled application and removal while preventing foreign objects from adhering to the patch surface. The structured design of the applicator creates a clean interface that protects the patch from contamination.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If manual attachment is used, then ease of operation is maintained, but reliability deteriorates due to folding and lifting phenomena

Engineering Contradiction:
Improveapplication simplicityVSAvoidadhesion consistency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The applicator acts as a controlled intermediary that ensures reliable patch attachment. The pressing element applies uniform pressure across the entire patch surface, preventing folding and lifting phenomena that occur with manual attachment. The handle provides stable user control, and the release sheet mechanism ensures clean attachment without compromising adhesion consistency.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs excessive pressing action through the pressing element to ensure complete and reliable adhesion. By applying more pressure than minimal requirements through the controlled pressing surface, the system guarantees that the patch adheres uniformly without folding or lifting, thereby enhancing reliability while maintaining operational simplicity.

Inventive Principle:
Principle #16Partial or excessive action
