Solution Overview

Problem

Existing personal cleansing devices lack a better feel, higher fragrance delivery, and convenience while maintaining deep cleaning effectiveness.

Innovation Solution

A sodium and potassium soap sponge is developed, comprising a combination of translucent and milky white soap bases with internal holes to provide air for increased bubble formation, along with a foaming surfactant agent, which is poured into a mold with a sponge, allowing the soap to solidify and providing a softer, more effective cleaning experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a substrate layer is used to bond soap to sponge, then the soap is mechanically supported, but the substrate insulates the soap from the sponge preventing direct transfer

Engineering Contradiction:

Improvemechanical supportVSAvoidsoap transfer

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The invention removes the substrate layer that was previously used to bond soap to sponge. By eliminating this insulating layer, the soap can be in direct contact with the sponge, allowing for effective transfer of soap to the sponge during use while the sponge itself provides the necessary mechanical support and structure.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If traditional bar soap is used, then deep cleaning occurs, but the feel is not soft and bubble formation is limited

Engineering Contradiction:

Improvedeep cleaningVSAvoidskin feel

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The invention creates a composite structure combining traditional bar soap with a sponge matrix. The soap is distributed throughout the sponge, creating a composite material that maintains the deep cleaning properties of traditional soap while adding the soft, bubbly characteristics of sponge. This composite structure allows the soap to be surrounded by air pockets in the sponge, enhancing bubble formation and providing a softer feel against the skin.

Inventive Principle:

Principle #40Composite materials

3Ease of operation

If more sponge is added to provide softness, then the feel improves, but the fragrance delivery and cleaning effectiveness may be reduced

Engineering Contradiction:

ImprovesoftnessVSAvoidfragrance delivery

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The invention applies local quality by distributing soap throughout the sponge matrix rather than having a uniform composition. The sponge provides softness in areas where it contacts the skin, while the soap distributed throughout maintains fragrance delivery and cleaning effectiveness. The local presence of soap within the sponge structure ensures that both the softening effect of the sponge and the cleaning properties of the soap are realized simultaneously in different locations.

Inventive Principle:

Principle #3Local quality
