Removable Coating for Solid Personal Care Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solid form personal care products face challenges such as slipperiness, water absorption, rapid degradation, and perceived hygiene issues, which existing solutions only partially address while often increasing production costs or compromising eco-friendliness.
Innovation Solution
A multifunctional protective coating system that encapsulates solid cosmetic and hygiene products with a removable, water-resistant coating, allowing at least one face to remain exposed for use. The coating can be removed through self-regulating degradation, mechanical means, or an embedded cord system, providing controlled exposure of fresh product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If solid bar forms are used to reduce packaging waste, then environmental friendliness is improved, but the products suffer from rapid degradation due to water absorption
Solution Approach 1:
The patent applies a thin film coating around the solid personal care product that acts as a moisture barrier. This flexible protective layer prevents water absorption while maintaining the solid bar form's environmental benefits, thereby extending product lifespan without compromising sustainability.
Solution Approach 2:
The invention creates a composite structure by combining the solid personal care product formulation with a protective coating material. This composite approach integrates the functional product with a protective shell that resists water and air, solving the degradation issue while preserving the eco-friendly solid bar format.
2Object-affected harmful factors
If solid bar forms are used to eliminate plastic packaging, then environmental friendliness is improved, but the products become slippery when wet leading to frequent dropping
Solution Approach 1:
The thin film coating provides a textured surface that enhances grip when wet. This flexible shell maintains the solid bar's environmental advantages while adding surface properties that prevent slipping and improve handling safety.
3Productivity
If all surfaces of the bar are exposed to water during use, then cleaning effectiveness is improved, but the product degrades much faster resulting in significant waste
Solution Approach 1:
The protective thin film coating allows the product to be used with water while preventing excessive water penetration. The coating enables effective cleaning contact between the product and skin while acting as a barrier that prevents bulk water absorption, thereby reducing product degradation and waste.
4Duration of action of stationary object
If traditional water-resistant formulations are used to reduce water absorption, then product lifespan is improved, but lathering and cleaning efficacy are reduced
Solution Approach 1:
The invention segments the product into two functional parts: the inner core containing the cleaning formulation optimized for lathering and efficacy, and the outer protective coating that provides water resistance. This segmentation allows each component to be optimized independently, maintaining cleaning performance while extending product lifespan.
Solution Approach 2:
The composite structure combines a cleaning-optimized formulation with a protective coating material. This allows the internal product to maintain high cleaning efficacy while the external coating provides water resistance, avoiding the need to compromise formulation performance for durability.

AI summary
A protective coating system for solid cosmetic and hygiene products comprises a removable, water-resistant coating that encapsulates the product while leaving at least one face exposed for use. The system includes multiple coating removal mechanisms: a self-regulating material designed to degrade synchronously with product use, an embedded cord system for manual removal, and a mechanical removal device integrated into a complementary cap. A base protection system provides additional functionality, allowing for the attachment of accessories. The coating protects the product from premature degradation, improves grip, and allows for controlled product use. This system extends product lifespan, enhances user experience, and provides an environmentally friendly alternative to excessive packaging. The versatility of the coating removal options accommodates various product types and user preferences, ensuring the benefits of the coating can be realized across a wide range of applications.
