Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a radiation source with defined emission characteristic is used and arranged in fixed arrays, then the device can be configured for a specific component and geometry, but human intervention is required to adapt the device to different components/geometries and manual adjustment is needed to achieve homogeneous radiation distribution
Solution Approach 1:
The system uses sensors to automatically measure the object geometry and reflectsivity, then the control device autonomously calculates and adjusts the radiation intensity distribution without manual intervention. The irradiation device self-adapts to different components by using the measurement data to generate appropriate irradiation patterns.
Solution Approach 2:
Sensors measure the actual radiation distribution on the object surface and feed this information back to the control device. The control device uses this feedback to adjust the radiation source intensity distribution, creating a closed-loop system that automatically achieves homogeneous irradiation.
2Manufacturing precision
If the incident radiation power decreases with the square of the distance from the radiation source (1/r² law), then the radiation distribution becomes non-homogeneous on complex geometries, but compensating for this requires complex device design and manual intensity distribution setting
Solution Approach 1:
Before irradiation, the system performs preliminary measurements of the object geometry and surface properties using sensors. The control device then pre-calculates the required intensity distribution pattern to compensate for the 1/r² law and complex geometry, setting up the irradiation device automatically without manual adjustment.
Solution Approach 2:
The control device dynamically adjusts the radiation intensity parameters of each sensor element based on its position relative to the object surface and the measured reflectsivity. By changing the intensity parameter individually for each sensor, the system compensates for distance variations and achieves uniform radiation distribution.
3Manufacturing precision
If special devices are designed for specific components and geometries to achieve homogeneous radiation distribution, then the radiation distribution requirement is met, but the device cannot be easily adapted to different components without human intervention
Solution Approach 1:
The irradiation device is designed with multiple sensors that can function both as radiation sources and as measurement sensors. This multi-functional design allows a single device to handle different components and geometries by switching between emission and detection modes, eliminating the need for specialized devices for each application.
Solution Approach 2:
The system dynamically switches between different operational modes (emission mode for irradiation, detection mode for measurement) and automatically adjusts the intensity distribution based on real-time object characteristics. This dynamic adaptability allows the same hardware to serve multiple purposes without manual reconfiguration.
