Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna is allowed to move freely in the slotted waveguide, then the antenna can accommodate vibrations and position deviations, but the antenna may leave the permissible range and cause interference or damage
Solution Approach 1:
The guide part acts as an intermediary component between the antenna and the slotted waveguide walls. It provides a controlled interface that allows the antenna to move within permissible limits while preventing it from leaving the waveguide, thus resolving the contradiction between adaptability and reliability
Solution Approach 2:
The guide part changes the mechanical constraints on the antenna by providing a controlled clearance range. This allows the antenna position parameter to vary within acceptable limits while maintaining reliable data transmission, effectively managing the trade-off between adaptability and reliability
2Reliability
If a guide part is added to limit the antenna position, then the antenna remains within permissible range, but the device complexity increases
Solution Approach 1:
The guide part is designed as a U-shaped component with leg sections that create clearance in the transverse direction. This simple geometric structure provides the necessary guidance and limitation functions without adding significant complexity to the overall system
Solution Approach 2:
The guide part serves as a simple intermediary element that mediates between the antenna and the waveguide constraints. Its U-shaped design with leg sections provides effective guidance while maintaining minimal structural complexity
3Object-generated harmful factors
If the guide part is made of electrically insulating material, then interference with other receivers is reduced, but the guidance friction increases
Solution Approach 1:
The guide part is designed with local quality differentiation: the leg sections have smooth surfaces facing the antenna to minimize friction, while the overall structure uses electrically insulating material to reduce electromagnetic interference. This localized optimization resolves the contradiction between electrical properties and friction
