Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple X-ray inspections are performed on electronic circuitry, then inspection quality and manufacturing precision are improved, but radiation exposure to the electronics increases and may cause damage
Solution Approach 1:
The system continuously monitors radiation exposure levels in real-time during X-ray inspections and provides feedback to the control system. When the accumulated radiation dose approaches the damage threshold of the electronics, the system automatically adjusts or halts the inspection process, enabling multiple inspections while preventing radiation-induced damage
Solution Approach 2:
The system determines the radiation damage threshold for specific electronic components before conducting inspections. By establishing these preliminary safety limits and integrating them into the inspection control logic, the system can perform multiple inspections within safe radiation boundaries, thereby improving inspection quality without exceeding damage thresholds
2Reliability
If real-time radiation monitoring is implemented, then protection from overexposure is improved, but system complexity increases due to additional detectors and signal processing components
Solution Approach 1:
The radiation detectors and signal processing unit serve multiple functions: they monitor radiation levels in real-time, accumulate dose data, compare readings against predetermined thresholds, and trigger automatic shutdown commands. This multi-functionality reduces the need for separate protection systems, thereby improving reliability without proportionally increasing overall system complexity
Solution Approach 2:
A microcontroller acts as an intermediary between the radiation detectors and the X-ray source control system. The microcontroller receives radiation signals, processes the data, determines when thresholds are exceeded, and automatically commands the X-ray source to shut down. This intermediary simplifies the control architecture while ensuring reliable protection against overexposure
