Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If carbon dating is performed on chewing gum products containing inorganic fillers, then carbon source identification is attempted, but measurement precision deteriorates due to interference from inorganic fillers
Solution Approach 1:
The patent applies extraction by removing inorganic fillers from the chewing gum sample before carbon dating analysis. The method separates organic components containing carbon from inorganic fillers that interfere with measurement, allowing accurate carbon source identification without contamination from filler materials.
Solution Approach 2:
The patent applies segmentation by dividing the chewing gum sample into separate organic and inorganic components. This segmentation allows the carbon dating process to be performed exclusively on the organic fraction, eliminating interference from inorganic fillers while preserving the ability to analyze the complete sample composition.
2Adaptability or versatility
If chewing gum is analyzed as a complex multi-component mixture, then comprehensive ingredient analysis is achieved, but device complexity increases making separation and identification difficult
Solution Approach 1:
The patent applies the intermediary principle by using solvent extraction as a mediating process between the complex chewing gum mixture and the carbon dating analysis. The solvent selectively interacts with organic components, facilitating their separation from inorganic fillers through a controlled chemical process that simplifies the overall analysis workflow.
Solution Approach 2:
The patent replaces complex mechanical separation methods with chemical extraction using solvents. This substitution allows for easier and more efficient separation of organic and inorganic components based on their different solubility properties, reducing the mechanical complexity of the separation process while maintaining comprehensive ingredient analysis capability.
