Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face challenges in determining their hair condition accurately and selecting appropriate care and styling products due to the time-consuming and costly nature of conventional methods, and existing wearables are not suited for measuring hair-related parameters.
Innovation Solution
A hair examination device equipped with a sensor system that detects both internal (hair and scalp) and external (environmental) data parameters, allowing for continuous, autonomous data collection and providing personalized recommendations based on multiple sensor values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional hair analysis methods are used, then measurement precision is improved, but loss of time and cost increase
Solution Approach 1:
The patent implements self-service by enabling consumers to perform their own hair condition analysis using a wearable device with integrated sensors. The device autonomously collects hair-related data (porosity, sebum content, thickness) and environmental data, processes it through algorithms, and provides actionable recommendations without requiring professional intervention, thus eliminating time loss and cost while maintaining measurement precision through continuous monitoring
Solution Approach 2:
The patent replaces mechanical/professional analysis systems with electronic sensor-based measurement. Multiple sensors (optical, electrical, thermal) automatically detect hair and scalp parameters, substituting the need for manual professional assessment. This electronic substitution enables continuous, autonomous data collection that is both precise and time-efficient
2Measurement precision
If conventional hair analysis methods are used, then measurement precision is improved, but cost increases
Solution Approach 1:
The patent employs a disposable or reusable wearable device that consumers can purchase at a fraction of the cost of professional analysis services. The device contains integrated sensors and processing capabilities that enable accurate hair condition monitoring without requiring ongoing payment to professionals, thus dramatically reducing cost while maintaining measurement precision through automated data collection and analysis
3Ease of operation
If existing wearables are used, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent achieves universality by designing a wearable device that simultaneously performs multiple functions: it monitors hair parameters (porosity, sebum, thickness), tracks environmental conditions (temperature, humidity, UV), and provides personalized recommendations. This multi-functional approach maintains ease of operation as a single wearable device while achieving comprehensive measurement precision across multiple hair condition parameters that previous single-function wearables could not deliver
