Personal care articles having multi-zone compliant personal care compositions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal care articles, such as bar soaps, are rigid and non-compliant, making them difficult to use effectively for cleansing, and often result in waste due to quick dissolution and the need for multiple products for desired cleansing and benefit properties, leading to inefficiency and environmental impact.
Innovation Solution
A personal care article comprising a multi-zone compliant personal care product and a water penetrable substrate, where the compliant product can conform to skin or hair surfaces and is designed for reusability, with controlled water flux to manage consumption and longevity, combining cleansing and benefit phases in a single product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If bar soap is made rigid for structural stability, then it maintains its shape, but it cannot conform to skin surfaces for effective cleansing
Solution Approach 1:
The personal care article transitions from a rigid state to a compliant state upon contact with water. The substrate and personal care composition are designed to become flexible and conformable when wet, allowing the article to adapt to skin contours during use while maintaining structural integrity during storage and handling.
Solution Approach 2:
The physical properties of the personal care article change in response to environmental conditions. Specifically, the substrate and composition undergo parameter changes when exposed to water, transforming from a non-compliant to a compliant state, enabling effective skin contact and cleansing performance.
2Reliability
If personal care composition is applied to implement for cleansing, then cleansing effectiveness is enhanced, but additional steps and water consumption increase
Solution Approach 1:
The personal care composition is integrated directly with the substrate to form a single unified article. This merging eliminates the need for separate application steps where consumers would otherwise need to apply liquid soap or body wash to the implement, reducing both time and water consumption while maintaining cleansing effectiveness.
Solution Approach 2:
The personal care article combines multiple functions into a single product: the substrate provides structural support and deliverability, while the personal care composition provides cleansing and benefit properties. This multi-functional design eliminates the need for separate cleansing products and implements.
3Ease of operation
If personal care composition is made compliant for skin conformity, then it conforms to body surfaces, but it dissolves quickly reducing reusability
Solution Approach 1:
The article exhibits dynamic properties where compliance is activated only during use when wet. The substrate maintains its structural form when dry but becomes compliant when wet, allowing the personal care composition to conform to skin surfaces during cleansing while the article retains its shape for repeated use.
Solution Approach 2:
The substrate acts as an intermediary that controls the interaction between water and the personal care composition. It allows the composition to become compliant and effective during use while preventing excessive water penetration that would cause rapid dissolution, thereby extending the article's usable life.
4Adaptability or versatility
If multiple personal care products are used for desired cleansing and benefit properties, then comprehensive care is achieved, but product clutter and waste increase
Solution Approach 1:
The personal care article incorporates multiple personal care compositions with different functions (cleansing, moisturizing, exfoliating, etc.) within a single substrate. This multi-functional design provides comprehensive skin care benefits while eliminating the need for multiple separate products, reducing clutter and waste.
Solution Approach 2:
Multiple personal care compositions that would traditionally require separate products are merged into a single integrated article. The substrate delivers different compositions to different areas or sequences of use, providing comprehensive care while reducing the total amount of packaging and material waste.

AI summary
A personal care article is disclosed having a compliant personal care product and a first water penetrable substrate adjacent to the compliant personal care product. The compliant personal care product includes two or more compliant personal care compositions, such that each of the compliant personal care compositions defines one or more zones and each compliant personal care composition physically contacts at least one of the other compliant personal care compositions.
