Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assessing masticatory force using color-changeable chewing gum lack objectivity and quantitativeness, as they are based on visual observation and not grounded in detailed color change studies during mastication.
Innovation Solution
A method involving a 4-parameter logistic curve regression equation is developed to correlate color difference with the number of mastication times, enabling a more objective and quantitative assessment of masticatory force by creating a color scale that closely conforms to the actual color change in the gum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual observation method is used to create color scale, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The invention transforms the subjective visual observation parameter into an objective quantitative parameter by using a 4-parameter logistic curve regression equation. The color difference values (ΔE) obtained through colorimetry are mathematically transformed into mastication time equivalents, creating an objective measurement scale that maintains ease of operation while significantly improving measurement precision.
2Measurement precision
If conventional sieve method is used to assess masticatory force, then measurement precision is improved, but device complexity worsens
Solution Approach 1:
The invention replaces the complex mechanical sieve method with a chemical-colorimetric system. Instead of using mechanical sieves to analyze particle size distribution, the invention uses color-changeable gum combined with colorimetry and mathematical modeling to assess masticatory force, thereby maintaining measurement precision while eliminating device complexity.
3Ease of manufacture
If color scale is created without detailed color change studies, then ease of manufacture is improved, but measurement precision deteriorates
Solution Approach 1:
The invention performs preliminary action by conducting detailed color change studies during mastication before creating the color scale. The regression equation is established in advance based on comprehensive colorimetric data collected at various mastication time points, ensuring that the resulting color scale is both easy to manufacture and highly precise in measuring masticatory force.

AI summary
Provided is a method for creating a color scale that can be used as more objective assessment criteria used for the evaluation of the masticatory force by a color-changeable chewing gum by analyzing the characteristics of the color change in the gum along with the progress in mastication in people having toothed jaws. A method for creating a color scale, comprising having a plurality of people having toothed jaws masticate color-changeable chewing gums, obtaining a regression equation for the color presented by the masticated gum and the color difference between the gum before and the gum after mastication, and further, obtaining a regression equation for the number of times of mastication and the color difference between the gum before and the gum after mastication, to thereby obtain the number of times of mastication performed by the people having toothed jaws and the color difference in the color presented by the masticated gum.
