Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual input of extensive parameters is used for melt flow rate testing, then testing accuracy and consistency are maintained, but operational complexity and time consumption increase significantly
Solution Approach 1:
The system automatically determines testing parameters by analyzing the sample type and selecting appropriate parameters from predetermined sets, eliminating the need for manual parameter configuration while maintaining measurement accuracy according to international standards
Solution Approach 2:
The system dynamically adjusts testing parameters based on the detected sample type, automatically selecting and modifying parameters such as temperature, load mass, and test duration to match the specific requirements of different polymer samples
2Measurement precision
If manual adaptation of parameters is performed for each sample type, then testing accuracy is maintained, but productivity and setup efficiency deteriorate
Solution Approach 1:
The system autonomously identifies sample types and automatically configures testing parameters without requiring operator intervention, enabling rapid setup for different sample types while maintaining accuracy through automated parameter selection based on predetermined standards
Solution Approach 2:
The system pre-configures multiple sets of testing parameters corresponding to different sample types before actual testing begins, allowing immediate selection and application of appropriate parameters when a sample is introduced, thereby eliminating time-consuming manual setup
3Reliability
If extensive manual parameter input is required, then testing reliability is ensured, but device complexity and operational burden increase
Solution Approach 1:
The system automatically manages parameter configuration by detecting sample types and selecting appropriate parameters from predetermined sets, reducing operational burden while maintaining reliable testing through automated compliance with international standards
Solution Approach 2:
The system provides a universal interface that handles multiple sample types through automated parameter selection, allowing a single device to reliably test various polymer materials without requiring complex manual configuration for each sample type
