Hair Roughness and Shine Gradient Assessment Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair assessment devices only measure properties using a single sensory aspect, either touch or appearance, failing to provide an accurate and simultaneous evaluation of hair roughness and shine, which limits their effectiveness in recommending targeted treatment regimes.
Innovation Solution
A device featuring an ascending gradient of shine and roughness, aligned inversely to each other, allowing users to visually compare hair samples against these gradients to assess both properties simultaneously, providing a more insightful evaluation of hair condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single sensory aspect (touch or appearance) is used to measure hair properties, then the device complexity is reduced, but the measurement precision and comprehensiveness of hair assessment deteriorates
Solution Approach 1:
The patent combines two previously separate measurement scales (roughness scale and shine scale) into a single integrated device. The roughness scale uses textured patterns to simulate hair surfaces while the shine scale uses reflective surfaces, both aligned on the same device body. This merging allows simultaneous assessment of both hair properties without requiring multiple separate devices, thereby maintaining simplicity while improving measurement comprehensiveness
Solution Approach 2:
The device serves multiple functions by incorporating both roughness assessment and shine assessment capabilities in a single instrument. The textured patterns on the roughness scale enable tactile evaluation of hair surface irregularities, while the reflective surfaces on the shine scale enable visual assessment of light reflection properties. This multi-functionality allows a single device to provide comprehensive hair condition evaluation
2Ease of operation
If only single property assessment is performed, then the ease of operation is improved, but the adaptability and versatility of the device deteriorates
Solution Approach 1:
The device is designed to assess multiple hair properties (roughness and shine) simultaneously through two integrated scales. Users can evaluate both tactile roughness through textured patterns and visual shine through reflective surfaces in a single operation, making the device adaptable to comprehensive hair condition assessments while maintaining ease of use through a unified design
3Ease of manufacture
If traditional single-scale devices are used, then the manufacturing cost is reduced, but the loss of information about hair condition deteriorates
Solution Approach 1:
The patent merges roughness and shine assessment scales into one device, capturing both tactile and visual hair properties simultaneously. The roughness scale uses textured patterns that replicate hair surface irregularities, while the shine scale uses reflective surfaces to assess light reflection. This combination prevents information loss about different aspects of hair condition that would occur if separate devices were used
