Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waveguide systems are sensitive to conductivity errors and interference, particularly when joining parts to form a channel for data signal transmission, which affects signal quality and polarization alignment.
Innovation Solution
The waveguide design features a channel with offset longitudinal axes and angular orientation, using ridges and recesses for precise mechanical and conductive bonding, minimizing interference and ensuring accurate polarization alignment and conductivity.

Engineering Contradiction Analysis
1Measurement precision
If the waveguide channel interface intersects the narrower walls to achieve correct polarization alignment, then data signal polarization is correct, but the waveguide becomes more sensitive to conductivity errors and interference
Solution Approach 1:
The waveguide channel is divided into multiple sections with different orientations. The first section has its longitudinal axis parallel to the first opening's first axis for reduced conductivity sensitivity, while the second section has its longitudinal axis parallel to the first opening's second axis for correct polarization alignment at the output.
Solution Approach 2:
The patent introduces a multi-dimensional orientation approach by rotating the channel longitudinal axis by 90 degrees between sections, transitioning from one orientation to another to simultaneously satisfy both conductivity sensitivity and polarization requirements.
2Strength
If conventional conductive sealant is used to join waveguide parts, then mechanical bonding is achieved, but the application is difficult to control and repeat, leading to inconsistent performance
Solution Approach 1:
The patent replaces the conventional mechanical application of conductive sealant with a controlled dispensing system that precisely applies the sealant along the joint line, ensuring consistent and repeatable bonding performance.
Solution Approach 2:
A positioning fixture or jig is introduced as an intermediary tool to hold the waveguide parts in precise alignment during assembly, ensuring that the interface between parts is accurately positioned before bonding.

AI summary
A waveguide for transmission of data signals therealong. Data signals are typically received from and/or transmitted to a remote location and subsequently passed to or emitted from the apparatus which allows the data to be processed. The waveguide includes a channel which has a cross-sectional shape, the angular orientation of which is changed at least one point along the length of the same so as to provide a waveguide which is less sensitive to interferences. The waveguide, in one embodiment, can also include recessed portions and/or ridges along the length of the channel which ensures that the waveguide can be formed in a more reliable and controlled manner.
