Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual collection methods are used, then system complexity is reduced, but production time increases and productivity decreases
Solution Approach 1:
The collection system automatically detects radioactivity levels and controls valve switching without manual intervention. The radio detector continuously monitors the fraction, and the control unit autonomously directs the fraction to appropriate collection vessels based on detected radioactivity, enabling the system to serve itself and eliminate manual operation bottlenecks.
Solution Approach 2:
Manual mechanical operations are replaced by an automated control system that uses radioactivity detection signals to electronically control valve switching. The control unit processes detector signals and automatically actuates valves, substituting manual mechanical control with an automated electromechanical system that increases speed and consistency.
2Manufacturing precision
If separation processes are extended to ensure purity, then manufacturing precision improves, but duration of action increases and time is lost
Solution Approach 1:
The radio detector provides continuous feedback on the radioactivity level of the separating fraction. The control unit uses this real-time feedback to dynamically control valve switching, ensuring that only fractions meeting purity criteria are collected. This closed-loop feedback system maintains high purity while minimizing separation time by immediately responding to changes in fraction composition.
Solution Approach 2:
The system pre-configures multiple collection vessels and establishes collection criteria before the separation process begins. The control unit is programmed with purity thresholds and automatically switches valves to appropriate vessels based on real-time detection, eliminating the need for extended post-separation analysis or reprocessing to ensure purity.
3Productivity
If automated control systems are implemented, then productivity increases, but device complexity and measurement requirements increase
Solution Approach 1:
The radio detector serves multiple functions: it monitors fraction composition, triggers valve switching, and provides data for quality control. This multi-functional device integrates detection and control functions into a single system component, reducing the need for separate measurement instruments and simplifying the overall system architecture despite the automated control implementation.
