Solution Overview

Problem

Conventional skincare and sunscreen products often have a greasy texture, making them difficult to apply and spread on the skin, and they may not provide a desirable feel, leading to poor user compliance with reapplication recommendations, especially for sunscreens which require frequent application to ensure adequate protection against solar ultraviolet radiation.

Innovation Solution

A skincare formulation comprising a pressure generating vehicle, such as compressed gases or liquid propellants, that mixes with the formulation to create a foam or whipped cream consistency upon application, enhancing ease of application, spreading, and absorption while maintaining a non-greasy feel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional skincare and sunscreen products are used, then skin protection function is provided, but the products have a greasy texture that makes them difficult to apply and spread

Engineering Contradiction:
Improveease of applicationVSAvoidgreasy texture
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent changes the physical state and delivery form of the skincare formulation from conventional liquid or cream to pressurized foam. This parameter change enables the product to be dispensed as a light, airy foam that applies easily without greasy residue, directly resolving the contradiction between ease of application and greasy texture

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent utilizes phase transition by incorporating propellants that transition from liquid to gas state upon pressurization, creating a foam structure. This phase transition allows the formulation to deliver active ingredients in a foam form that spreads easily and absorbs quickly, eliminating the greasy feel while maintaining skin protection functionality

Inventive Principle:
Principle #36Phase transitions

2Reliability

If conventional skincare formulations are used, then skin protection is provided, but the greasy feel leads to poor user compliance with reapplication recommendations

Engineering Contradiction:
Improveuser complianceVSAvoidgreasy feel
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

By changing the delivery system to pressurized foam, the patent creates a product with superior sensory attributes (light, non-greasy feel) that users are more likely to accept and reapply. This parameter change directly addresses the compliance issue by eliminating the greasy feel that discourages reapplication

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The foam formulation provides self-service benefits through its unique texture and rapid absorption properties. The product automatically feels pleasant upon application without requiring additional steps, making users more likely to comply with reapplication recommendations for maintaining skin protection

Inventive Principle:
Principle #25Self-service

3Productivity

If conventional sunscreen formulations are used, then UV protection is provided, but the products are difficult to spread and absorb slowly

Engineering Contradiction:
Improvespreading speedVSAvoiddifficult to spread
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent employs phase transition of propellants from liquid to gas to create a foam structure that inherently spreads rapidly. The foam's air-filled structure allows it to cover large skin areas quickly and absorb faster than conventional formulations, directly improving productivity in terms of spreading speed while eliminating the difficulty of application

Inventive Principle:
Principle #36Phase transitions

4Object-generated harmful factors

If conventional lotion formulations are used, then skin moisturization is provided, but the products leave a greasy residue on the skin

Engineering Contradiction:
Improvegreasy residueVSAvoidresidue on skin
Core Design Contradiction:
Object-generated harmful factorsVSQuantity of substance

Solution Approach 1:

The patent changes the physical delivery form from conventional liquid lotion to pressurized foam, which inherently reduces residue. The foam structure allows for more efficient delivery of moisturizing ingredients with less overall product needed, and the rapid absorption characteristics minimize greasy residue on the skin surface

Inventive Principle:
Principle #35Parameter changes

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
