Solution Overview
Problem
Existing data transmission systems between stationary and mobile parts, particularly in rail-guided systems, face challenges in achieving a high signal-to-noise ratio and reducing interference, which affects the reliability and efficiency of data exchange.
Innovation Solution
A slotted waveguide arrangement with a symmetrical cross-section and eccentrically positioned antennas, combined with offset comb reflectors and a simple connection technique, is used to effectively excite the H10 mode of electromagnetic waves, enhancing data transmission quality and reducing noise interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a slotted waveguide with symmetrical cross-section is used for data transmission, then the structure is simple and manufacturing is easy, but the signal-to-noise ratio is insufficient and interference is high
Solution Approach 1:
The patent introduces asymmetry by positioning the antenna eccentrically in one of the sub-areas rather than at the center, and by offsetting the comb reflectors relative to each other in the direction of travel. This asymmetric configuration selectively excites the H10 mode of electromagnetic waves while suppressing other modes, thereby improving the signal-to-noise ratio and reducing interference without complicating the overall waveguide structure
2Power
If multiple oscillation modes are excited in the waveguide, then more energy can be transmitted, but interference increases and data transmission errors increase
Solution Approach 1:
The patent applies local quality by creating specific local conditions within the waveguide: the antenna is positioned in a specific sub-area rather than centrally, and comb reflectors are placed at specific offset positions. These localized asymmetric arrangements create the appropriate boundary conditions to selectively excite only the H10 mode, ensuring high-quality data transmission with minimal interference
