Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed radiation distribution is used in the treatment chamber, then the microwave treatment device is simple to operate, but it cannot be adapted to different objects or treatment procedures
Solution Approach 1:
The microwave emission device is divided into multiple individually controllable emitters arranged in an array. Each emitter can be controlled independently to vary the radiation distribution, allowing adaptation to different objects without mechanical modifications to the overall device structure.
Solution Approach 2:
The radiation distribution is made dynamically adjustable through electronic control of individual emitter activation and power levels. This allows the system to adapt to different treatment requirements by changing which emitters are active and at what power, rather than requiring physical reconfiguration.
2Adaptability or versatility
If the microwave emitter is modified to achieve different radiation distributions, then adaptability to different objects is improved, but the effort required for modification is high
Solution Approach 1:
The emitter array is designed with multiple independently controllable elements from the outset. This segmentation allows different radiation distributions to be achieved by simply changing which segments (emitters) are activated and at what power levels, eliminating the need for physical modifications to the device structure.
Solution Approach 2:
Different radiation distributions are achieved by changing operational parameters (which emitters are active and their respective power levels) rather than changing physical parameters (emitter arrangement or orientation). This allows rapid adaptation without mechanical work.
3Reliability
If a resonator treatment chamber is used, then consistent radiation distribution is achieved, but the system cannot be easily adapted to varying treatment requirements
Solution Approach 1:
The resonator chamber is paired with a segmented emitter array where individual emitters can be controlled independently. This allows the system to maintain the consistent radiation distribution benefits of the resonator while adapting to different treatments by selectively activating specific emitter segments.
Solution Approach 2:
Different regions of the treatment chamber can receive different radiation intensities by selectively activating specific emitters in the array. This allows local customization of radiation distribution within the resonator chamber to suit different treatment requirements while maintaining overall system consistency.
