Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual adjustment of film extrusion line parameters and selection of raw materials based on operator experience and testing is used, then film production can be performed with existing knowledge and skills, but the production process becomes lengthy and costly
Solution Approach 1:
The patent replaces manual operator experience and testing with an automated computer-based system that uses databases and algorithms to select raw materials and adjust extrusion parameters. The system automatically processes film orders, retrieves relevant data from databases, calculates optimal production parameters, and controls the extrusion line without manual intervention, thereby reducing production time while increasing automation.
2Manufacturing precision
If extensive testing and preparation are performed to achieve desired film properties, then film quality can be ensured, but production costs increase
Solution Approach 1:
The patent performs preliminary actions by pre-storing comprehensive data in databases about raw materials, machine parameters, and their relationships. Before actual film production, the system pre-calculates optimal production parameters and raw material selections based on stored data and film specifications, eliminating the need for extensive testing during production and reducing both costs and complexity.
Solution Approach 2:
The system incorporates feedback mechanisms where production results and film properties are measured and fed back into the database. This feedback loop allows the system to continuously improve its predictions and parameter selections, ensuring high film quality accuracy while reducing the need for repeated testing and adjustments.
3Adaptability or versatility
If multiple parameters and settings are adjusted at many points in the film extrusion line, then desired film properties can be achieved, but the adjustment process becomes complex and time-consuming
Solution Approach 1:
The patent implements a universal computer-based control system that integrates multiple functions: database management, parameter calculation, raw material selection, and machine control. This single multi-functional system manages all parameter adjustments across the extrusion line, coordinating temperatures, pressures, and other physical variables through one integrated platform, thereby maintaining high adaptability while reducing overall system complexity.
