Solution Overview
Problem
Current methods for determining hair condition are inadequate in accurately assessing damage and providing personalized cosmetic recommendations, as they do not effectively account for individual hair characteristics and damage levels, particularly oxidative damage.
Innovation Solution
A hair condition-determining device equipped with an optical sensor and light source, which illuminates the hair and detects light interactions to assess damage through fluorescence and near-infrared spectroscopy, providing detailed information on hair condition and recommending suitable treatments or products based on cysteic acid content and other parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional hair condition assessment methods are used, then the assessment process is simple, but the measurement precision and accuracy of hair damage determination is insufficient
Solution Approach 1:
The patent replaces conventional mechanical/visual hair assessment methods with an optical measurement system. The device uses light sources to illuminate hair and optical sensors to detect light interactions, enabling objective quantification of hair damage through optical properties rather than subjective visual inspection.
Solution Approach 2:
The patent introduces light as an intermediary substance to assess hair condition. Light interacts with hair samples, and the modified light carries information about hair damage that can be detected and analyzed, providing an indirect but precise measurement method.
2Adaptability or versatility
If general hair assessment methods are used, then the device is easy to operate, but the ability to provide personalized cosmetic recommendations is insufficient
Solution Approach 1:
The patent implements a feedback system where the optical sensor measurements of hair condition are processed by an electronic circuit device that generates personalized cosmetic recommendations. The system continuously adapts recommendations based on measured hair parameters, creating a closed-loop personalized care system.
Solution Approach 2:
The patent measures multiple optical parameters of hair (light absorption, reflection, transmission characteristics) to characterize hair condition comprehensively. By analyzing changes in these optical parameters, the system can detect hair damage levels and adapt cosmetic recommendations accordingly.
3Reliability
If detailed hair condition analysis is performed, then the treatment efficacy can be improved, but the measurement and detection difficulty increases
Solution Approach 1:
The patent segments the hair sample into different regions (first region and second region) to enable comparative analysis. By measuring optical properties of different hair segments, the device can detect variations and changes in hair condition more reliably than measuring the entire hair mass as a whole.
Solution Approach 2:
The patent employs periodic illumination of hair with light and periodic measurement of optical interactions. This repeated measurement approach allows for tracking hair condition changes over time and improving measurement reliability through multiple data points.
