Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test systems are not suitable for small test chambers, particularly due to the size constraints of the quiet zone, and require separate cables for connecting the multiplexing part with the feedthrough, which occupies valuable space.
Innovation Solution
An antenna assembly with a multiplexing part integrated within the feedthrough part, minimizing space requirements by eliminating the need for separate cables and providing bidirectional waveguide inputs and outputs for signal processing and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If separate cables are used to connect the multiplexing part with the feedthrough, then signal transmission is achieved, but the space required increases and the device complexity increases
Solution Approach 1:
The patent integrates the multiplexing part directly into the feedthrough structure, merging two previously separate components (multiplexing part and feedthrough) into a single integrated unit. This eliminates the need for separate cable connections between these components, thereby reducing the space required in the test chamber and simplifying the overall device architecture while maintaining signal transmission functionality.
2Volume of moving object
If the multiplexing part is integrated within the feedthrough part, then space is minimized and device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The multiplexing part is integrated within the feedthrough part as a single unified structure, eliminating the need for separate cable connections and reducing the space required in the test chamber. This integration approach minimizes the overall device volume while the design accommodates standard manufacturing tolerances through appropriate structural design.
3Area of stationary object
If cables are located within the test chamber, then signal transmission to the antenna is achieved, but the quiet zone size is reduced and test system complexity increases
Solution Approach 1:
By integrating the multiplexing part into the feedthrough structure, the patent eliminates the need for cables to traverse through the test chamber interior. This frees up space within the quiet zone, increasing its effective area for device under test placement, while also simplifying the cable arrangement by reducing the number of cables required.
