Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the waveguide dimensions are fixed to determine transmitted frequencies, then the waveguide structure is simple and stable, but changing frequency range requires waveguide replacement leading to increased cost and time
Solution Approach 1:
The waveguide transitions from a static structure with fixed dimensions to a dynamic structure where the inner wall can be adjusted. The inner wall controller modifies the inner wall dimensions in real-time, allowing the waveguide to adapt to different frequency ranges without physical replacement, thus resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The invention changes the physical parameters of the waveguide by adjusting the inner wall dimensions through the inner wall controller. By varying the inner wall size, the waveguide can transmit different frequency ranges, achieving frequency adaptability while maintaining a relatively simple overall structure.
2Reliability
If the waveguide is replaced to change frequency range, then the frequency range is accurately matched, but system realignment time and cost increase
Solution Approach 1:
The dynamic adjustment capability allows the waveguide to be reconfigured for different frequency ranges without replacement. The inner wall controller can quickly modify the inner wall dimensions to match the desired frequency range, eliminating the time-consuming replacement and realignment process while maintaining accurate frequency matching.
Solution Approach 2:
The waveguide performs its own adaptation to different frequency ranges through the inner wall controller, eliminating the need for external replacement and realignment operations. The system adjusts itself to maintain optimal performance across different frequency ranges.
3Reliability
If the waveguide is replaced to change frequency range, then the frequency range is accurately matched, but cost increases
Solution Approach 1:
The waveguide is designed as a universal structure that can handle multiple frequency ranges through the adjustable inner wall. Instead of requiring multiple specialized waveguides for different frequency ranges, a single waveguide with adjustment capability serves multiple functions, reducing overall system cost while maintaining accurate frequency matching.
Solution Approach 2:
By changing the inner wall parameters dynamically, the waveguide achieves accurate frequency range matching without requiring multiple physical waveguide units. This parameter-based adjustment approach eliminates the need for expensive replacements and reduces the overall system cost.
