Hair Fiber Degradation Assessment via Segment Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assessing the physical state of hair fibres are not efficient in providing a rapid and accurate evaluation of hair degradation, as they often rely on measuring moisture content differentials or visual inspections, which do not effectively quantify the rate of degradation or provide actionable insights for individual hair fibres.
Innovation Solution
A method involving the comparison of physical attributes at the crossing point of a hair fibre, specifically within the root and tip regions, using a device with a comparison plate and imaging capabilities to assess attributes like colour, width, shine, and transparency, allowing for a detailed evaluation of degradation rate and integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If moisture content differential measurement is used to assess hair damage, then a quantitative assessment can be obtained, but the method does not effectively quantify the rate of degradation or provide actionable insights for individual hair fibres
Solution Approach 1:
The hair fibre is divided into multiple segments along its length, with each segment's physical attributes measured independently. This segmentation allows for the calculation of degradation rate by comparing attributes between the root region (less damaged) and tip region (more damaged), providing both quantitative assessment and actionable insights about the rate of degradation.
2Measurement precision
If physical handling or high magnification visualization methods are used to measure hair fibre state, then detailed observation is possible, but the assessment is time-consuming and not rapid
Solution Approach 1:
The patent replaces manual physical handling and visual inspection methods with an automated measurement system that uses optical or imaging technology to capture and analyze hair fibre attributes. This substitution maintains measurement precision while dramatically increasing assessment speed and productivity.
3Productivity
If general assessment of many hair fibres simultaneously is performed, then overall hair condition can be evaluated, but individual fibre degradation rate cannot be determined
Solution Approach 1:
The measurement system evaluates each hair fibre individually by segmenting the fibre into root and tip regions, measuring physical attributes at each segment, and calculating degradation rate specific to that individual fibre. This approach maintains productivity by automating the process while preserving individual fibre information.
Solution Approach 2:
The system provides feedback by comparing measured attributes against reference values or previous measurements, enabling determination of degradation rate for each individual fibre. This feedback mechanism allows the system to maintain high productivity while delivering detailed individual fibre assessments.
