Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional copper conductors are inadequate for transmitting high-frequency signals, and existing waveguide connectors lack effective self-alignment features to ensure accurate connections between waveguides, leading to signal loss and misalignment issues.
Innovation Solution
A waveguide connector with a male and female part that includes self-alignment features, such as alignment channels and conductive materials like silver-plated copper or gold-plated brass, to form a blind-mate electrical connection, correcting for misalignments and ensuring secure coupling between waveguides with conductive channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional copper conductors are used for signal transmission, then the connection is simple and inexpensive, but signal loss increases at high frequencies
Solution Approach 1:
The patent replaces traditional copper conductor connections with a waveguide connector system that uses mechanical coupling between male and female parts. This substitution eliminates the limitations of copper conductors at high frequencies by using a dedicated waveguide interface with self-alignment features, thereby reducing signal loss while maintaining ease of connection through the blind-mate design
2Reliability
If waveguide connectors without self-alignment features are used, then the structure is simpler, but misalignment occurs leading to connection reliability issues
Solution Approach 1:
The connector incorporates self-alignment features including alignment channels and alignment features that automatically guide the male and female parts into proper alignment during the connection process. This self-aligning mechanism ensures reliable electrical connection without requiring external alignment tools or complex adjustment procedures, thereby improving connection reliability while keeping the overall structure manageable
Solution Approach 2:
The alignment channels act as intermediary structures that facilitate the alignment between male and female connector parts. These channels provide a guided path that ensures proper positioning during connection, serving as a mediator that resolves the misalignment issue without requiring complex external alignment mechanisms
3Manufacturing precision
If manual alignment procedures are used for waveguide connections, then alignment precision can be improved, but operation time and complexity increase
Solution Approach 1:
The self-alignment features enable the connector to automatically correct misalignments during the connection process itself, eliminating the need for separate manual alignment procedures. The alignment channels and alignment features work together to guide the parts into proper position as they are being connected, thereby achieving high alignment precision while maintaining ease and speed of operation through the blind-mate design

AI summary
An example waveguide connector is for making a blind-mate electrical connection between a first waveguide and a second waveguide. The waveguide connector includes a male part connected to the first waveguide, where the first waveguide includes a first conductive channel, and a female part connected to the second waveguide, where the second waveguide includes a second conductive channel. The female part includes a receptacle into which the male part slides to create the blind-mate electrical connection between the first conductive channel and the second conductive channel. A self-alignment feature is on at least one of the male part or the female part. The self-alignment feature is configured to guide the male part into the receptacle while correcting for misalignment of the male part and the female part.
