Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional waveguide switches are used for signal switching, then good electrical performance is achieved, but precision manufacturing requirements increase and costs rise
Solution Approach 1:
The waveguide switch is divided into two separate non-contact parts: an inner cylinder and an outer cube. This segmentation eliminates the need for precise physical contact and alignment between components, reducing manufacturing precision requirements while maintaining electrical performance through electromagnetic field coupling via iris structures.
2Productivity
If frequency increases to improve signal transmission, then transmission efficiency improves, but the size of the switch decreases making manufacturing more difficult
Solution Approach 1:
The inner cylinder is designed to rotate within the outer cube, providing dynamic switching capability. This rotational mechanism allows the switch to handle high-frequency signals effectively while maintaining a compact size that is easier to manufacture, as the dynamic structure reduces the need for extremely precise static alignment at high frequencies.
3Reliability
If physical contact between waveguide components is used, then signal transmission is achieved, but production and integration costs increase
Solution Approach 1:
Iris structures are introduced as intermediary elements between the inner cylinder and outer cube. These irises create electromagnetic coupling that enables signal transmission without direct physical contact between the main components, reducing production and integration costs associated with precision mechanical contact while maintaining reliable signal transmission.

Function Achieved in This Case
This design allows for efficient and cost-effective signal switching between two inputs and two outputs by rotating the inner cylinder, ensuring precise signal directionality and minimizing signal loss through non-contact parts, thus addressing the manufacturing and cost challenges of existing waveguide switches.
Implementation Method 1
the signal is transmitted to the waveguide processed into the inner cylinder without spreading into the gap between the outer cube and the inner cylinder. In this way, the signal transmission between the two non-contact parts is lossless.

AI summary
Disclosed is an iris waveguide switch capable of efficiently transmitting and switching a signal between two desired inputs and two desired outputs in high power applications, which is generally used in various applications such as millimeter wave radar, satellite systems and RF test setup. The iris waveguide switch includes two main parts: an inner cylinder and an outer cube. Periodic irises prevent the signal propagating through the gap between the inner cylinder and the outer cube to the side surface of the inner cylinder, guiding the signal into the inner cylinder bend. The inner cylinder, rotated by a drive mechanism, switches the incoming signal between two inputs and two outputs.
