Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If parameters of the pyrolysis system are determined according to experiences in the related art, then the system can operate with simple configuration, but the accuracy and reliability of parameter verification deteriorates
Solution Approach 1:
The patent creates a scaled-down test reactor that copies the essential features and structure of the actual industrial pyrolysis system. This test reactor allows accurate parameter verification through controlled experiments while maintaining simpler operation and measurement capabilities compared to full-scale industrial systems.
Solution Approach 2:
The patent introduces a intermediate test device that serves as a mediator between theoretical parameter determination and full-scale industrial application. This test reactor enables systematic verification of parameters before industrial deployment, improving reliability without requiring direct modification of complex industrial systems.
2Reliability
If a comprehensive test device with multiple functions is designed to verify all pyrolysis parameters, then measurement accuracy improves, but device complexity and ease of operation deteriorates
Solution Approach 1:
The test reactor is designed with multi-functional capabilities to verify multiple pyrolysis parameters (temperature, pressure, gas composition, reaction kinetics) within a single integrated system. This universal design improves verification reliability while avoiding the need for multiple separate test devices, thereby maintaining operational simplicity.
Solution Approach 2:
The patent combines multiple measurement and control functions into an integrated test system. Sensors for temperature, pressure, and gas composition are merged with the reactor design, and control systems are consolidated to simplify operation while comprehensively verifying all critical parameters.
