Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual composition analysis of coiled tobacco leaves is performed, then the analysis can be conducted with simple equipment, but the work intensity is high and the analysis results are vague and not referential
Solution Approach 1:
The patent replaces manual mechanical analysis methods with thermogravimetric analysis instrumentation. The TG/DTA instrument automatically performs heating, weight measurement, and data processing, substituting the manual mechanical operations with an automated thermal analysis system that provides objective, quantitative results without high work intensity.
Solution Approach 2:
The patent transforms the analysis from qualitative manual evaluation to quantitative thermal parameter measurement. By measuring weight changes as a function of temperature (thermal parameters), the system converts subjective manual assessment into objective numerical data that is precise, repeatable, and referential.
2Ease of manufacture
If manual composition analysis of coiled tobacco leaves is performed, then the equipment requirements are simple, but the analysis results lack objectivity and precision
Solution Approach 1:
The patent replaces manual mechanical analysis with automated thermogravimetric analysis. The instrument precisely measures weight changes at different temperatures, providing objective quantitative data that eliminates subjectivity and enhances measurement precision compared to manual methods.
Solution Approach 2:
The patent creates a thermal analysis fingerprint (TG/DTA curve) that copies and represents the compositional characteristics of tobacco leaves. This thermal signature serves as an objective replica of the sample's composition, enabling precise identification and analysis without subjective human interpretation.
3Ease of manufacture
If sensory evaluation methods are used for tobacco analysis, then no special equipment is needed, but the subjectivity is strong and conclusions are vague
Solution Approach 1:
The patent replaces subjective sensory evaluation with objective thermogravimetric analysis. The instrument automatically measures weight changes during heating, generating quantitative thermal curves that provide reliable, repeatable, and objective data free from human subjectivity while requiring only standard laboratory equipment.
4Ease of operation
If traditional tobacco analysis methods are used, then the process is simple to implement, but the workload is high and efficiency is low
Solution Approach 1:
The patent replaces manual analytical procedures with automated thermogravimetric analysis. The instrument autonomously performs sample heating, weight measurement, data acquisition, and curve generation, dramatically reducing analyst workload and time requirements while maintaining operational simplicity through automated workflows.
Solution Approach 2:
The thermogravimetric analysis system performs self-service by automatically conducting the entire analysis process without continuous human intervention. The instrument independently controls heating programs, measures weight changes, processes data, and generates results, minimizing analyst involvement and maximizing analysis efficiency.
