Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual monitoring and adjustments are used in the flaking operation, then the system is simpler and easier to manufacture, but the production consistency and moisture content control deteriorate
Solution Approach 1:
The system employs a feedback mechanism where a moisture sensor continuously monitors the moisture content of the corn flakes and sends signals to a PLC controller. The PLC automatically adjusts the steam valve position based on the feedback signal, creating a closed-loop control system that maintains consistent moisture content without manual intervention.
Solution Approach 2:
The flaking system performs self-adjustment through automated control. The PLC controller autonomously regulates the steam injection and roller pressure based on real-time moisture measurements, eliminating the need for constant manual monitoring and adjustments while maintaining production consistency.
2Productivity
If manual adjustments are made frequently, then the system can adapt to changes, but the labor cost and time consumption increase
Solution Approach 1:
The automated control system operates continuously without interruption. The moisture sensor constantly monitors the flaking process, and the PLC continuously adjusts steam and pressure parameters, ensuring uninterrupted production while eliminating the periodic interruptions caused by manual adjustments.
Solution Approach 2:
The system replaces manual mechanical adjustments with an automated control system. The PLC controller substitutes for human operators, using electronic signals to control the steam valve and roller pressure, thereby eliminating the time and labor required for manual intervention while maintaining continuous production.
3Manufacturing precision
If automated control systems are implemented, then the consistency and uniformity of flakes improve, but the device complexity and initial cost increase
Solution Approach 1:
The system uses a feedback loop where moisture sensor readings are continuously sent to the PLC controller, which automatically adjusts steam and pressure parameters. This closed-loop control ensures uniform flake production by maintaining consistent moisture content throughout the process without requiring complex manual intervention systems.
Solution Approach 2:
The PLC controller acts as an intermediary between the moisture sensor and the steam valve/roller pressure system. It processes sensor signals and translates them into appropriate control actions, simplifying the overall system architecture while achieving precise control over flake uniformity and moisture content.
