Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hair bleaching compositions are opaque, making it difficult to visualize the bleaching process, requiring rinsing to assess lightening progress and potentially leading to overapplication or underapplication of product.
Innovation Solution
Development of transparent ready-to-use bleaching compositions combining oxidizing agents, non-acrylic thickening polymers, acrylic polymers, hydrogen peroxide, and polyurethane polyethers, allowing for clear application and monitoring of hair lightening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If traditional opaque bleaching compositions are used, then the composition provides adequate bleaching function, but it is difficult to visualize the bleaching process and requires rinsing to assess progress
Solution Approach 1:
The patent applies the color changes principle by transitioning from opaque to transparent composition formulation. This allows the hair underneath to be visible through the applied product, enabling real-time monitoring of the lightening process without requiring rinsing. The transparent nature of the composition reveals the hair's color progression as bleaching occurs.
Solution Approach 2:
The patent uses the transparent composition itself as an intermediary medium that does not obstruct visual observation. Rather than requiring a separate assessment step (rinsing), the composition acts as a transparent window through which the hair's color change can be directly observed during the entire processing time.
2Measurement precision
If opaque bleaching compositions are used, then the composition maintains stability, but it requires physical removal to assess lightening progress
Solution Approach 1:
The transparent composition enables direct visual measurement of lightening progress by allowing observation of the hair's color transformation. This eliminates the need for complex assessment procedures involving removal and reapplication of the product.
Solution Approach 2:
The composition provides self-assessment capability through its transparent nature. The user can directly observe the bleaching progress without needing to perform additional operations such as rinsing and reapplication, making the assessment process simpler and more intuitive.
3Difficulty of detecting and measuring
If transparent bleaching compositions are developed, then real-time visualization is enabled, but the formulation complexity increases
Solution Approach 1:
The patent achieves transparency by modifying the formulation parameters of the bleaching composition. Specific adjustments to the chemical composition and concentration ratios of ingredients are made to transition from an opaque to a transparent state, enabling visualization while maintaining bleaching efficacy.
Solution Approach 2:
The transparent bleaching composition is formulated as a composite material system that combines multiple ingredients in specific proportions. The formulation integrates oxidizing agents, alkalizing agents, and other components in a way that achieves both transparency and functional performance.
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
Enables real-time visualization of hair lightening, reducing the need for rinsing to assess progress and ensuring accurate application, resulting in more efficient and effective hair bleaching.
Implementation Method 1
The process of lifting the color of hair, also known as lightening, generally requires the use of compositions that comprise at least one oxidizing agent
Implementation Method 2
The alkalizing agent causes the hair shaft to swell, thus allowing the small oxidative dye molecules to penetrate the cuticle and cortex
