Solution Overview

Problem

Existing body scrub and shave preparation products are typically formulated as separate entities, leading to inconvenience and waste, as they do not effectively transform to provide both exfoliation and enhanced shave comfort in a single application.

Innovation Solution

A topical composition that includes exfoliation particles selected to break down or dissolve during use, combined with a cosmetically acceptable carrier, which transforms from a body scrub to a shave preparation, providing both exfoliation and improved shave comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If scrub products are formulated to provide a large quantity of exfoliation particles and increase residence time to maximize exfoliation, then exfoliation effectiveness is improved, but sensory profile becomes unfavorable for shave process and consumers wash away the product

Engineering Contradiction:
Improveexfoliation effectivenessVSAvoidsensory profile for shave
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The scrub product dynamically changes its properties during use. Initially, it contains a high concentration of exfoliation particles for effective exfoliation. As the product is applied and worked into the skin, the particles gradually break down and dissolve, transforming the product from a coarse scrub into a smoother, more shave-friendly formulation that provides both exfoliation and comfortable shave experience

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The product formulation undergoes parameter changes during application. The concentration of exfoliation particles decreases over time as they break down, while the carrier base and soothing ingredients become more prominent. This parameter transformation allows the product to serve dual purposes: initial exfoliation followed by comfortable shave preparation

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If shave preparations are formulated to avoid ingredients that impart unfavorable sensory attributes, then shave comfort is improved, but the product cannot provide effective exfoliation

Engineering Contradiction:
Improveshave comfortVSAvoidexfoliation effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The shave preparation product performs preliminary exfoliation action before the shave process. By incorporating exfoliation particles that break down during application, the product prepares the skin surface in advance, removing dead skin cells and smoothing the skin texture before shaving, thereby enhancing overall shave comfort without interfering with the shaving process itself

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The shave preparation product combines multiple functions in a single formulation: it provides exfoliation through breaking down particles, soothes the skin with calming ingredients, and creates an optimal surface for shaving. This multi-functionality eliminates the need for separate scrub and shave prep products, addressing both exfoliation needs and shave comfort requirements

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If separate scrub and shave preparation products are used, then each product can be optimized for its specific function, but consumer convenience decreases and resource waste increases

Engineering Contradiction:
Improveproduct optimizationVSAvoidconsumer convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention merges the functions of separate scrub and shave preparation products into a single unified product. The formulation combines exfoliation particles, soothing ingredients, and carrier bases that work together to provide both exfoliation and shave preparation benefits, eliminating the need for consumers to purchase, store, and apply multiple separate products

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The unified product serves multiple purposes: it acts as an exfoliating scrub when first applied, then transforms into a shave preparation as particles break down. This multi-functionality allows a single product to replace two separate products, optimizing both functions while improving consumer convenience and reducing resource waste

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

The topical composition effectively exfoliates the skin during the exfoliation process and enhances shave comfort by remaining on the skin and providing a better sensory profile compared to using separate products.

Implementation Method 1

The exfoliation particle is selected to break down or dissolve when the topical composition is used on the body part

Methodology Applied
Scientific EffectBreak down:

Implementation Method 2

The cosmetically acceptable carrier disperses the exfoliating particle and delivers the exfoliating particle to the body part

Methodology Applied
Scientific EffectDispersion: Dispersion (of waves)

Implementation Method 3

the cleansing surfactant mixes with the water to provide a lather effect that causes the topical composition to remain on the skin

Methodology Applied
Scientific EffectSurfactant action: Surfactant

AI summary

Embodiments relate to a topical composition including an exfoliation particle selected to break down or dissolve when the topical composition is rubbed on skin of a body part. The topical composition further includes a cosmetically acceptable carrier to disperse the exfoliating particle in the topical composition and deliver the exfoliating particle to the skin or the body part. The topical composition is formulated to exfoliate skin during an exfoliation process and subsequently enhance shave quality during a shave process involving the body part by transformation from a body scrub into a shave preparation during use as a two-in-one body scrub and shave preparation composition.
