Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waveguide-microstrip line converters have a fixed connection between feeder wires on a circuit board and waveguide cables, limiting the ability to connect or disconnect them arbitrarily, which is inconvenient for systems transmitting millimeter-wave or microwave signals.
Innovation Solution
A connector apparatus with a detachable hollow waveguide structure that allows for easy connection and disconnection between the circuit board and waveguide cable, utilizing a hollow waveguide interposed between the connector units on the circuit board and waveguide cable, enabling arbitrary connection and disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waveguide-microstrip line converter is used to connect feeder wire and waveguide cable, then signal transmission is enabled, but the connection becomes fixed and cannot be disconnected arbitrarily
Solution Approach 1:
The connector is divided into separate first and second connector units that can be detachably coupled. The first connector unit is fixed to the circuit board while the second connector unit is detachably coupled to the waveguide cable, allowing the connection to be segmented and reconfigured as needed.
Solution Approach 2:
The connector transitions from a fixed static connection to a dynamic detachable connection. The detachable coupling mechanism allows the connection state to change between connected and disconnected, providing operational flexibility while maintaining signal transmission when connected.
2Stability of the object's composition
If a fixed connection structure is used between circuit board and waveguide cable, then connection stability is ensured, but the ability to connect and disconnect arbitrarily is lost
Solution Approach 1:
The connector is segmented into a first connector unit fixed to the circuit board providing stability, and a second connector unit detachably coupled to the waveguide cable enabling easy operation. This segmentation allows the stable portion to remain fixed while the operational portion can be easily connected and disconnected.
Solution Approach 2:
The detachable coupling mechanism acts as an intermediary between the fixed first connector unit and the waveguide cable. This intermediary provides both the stability of a fixed connection when engaged and the ease of operation for connection and disconnection.
3Adaptability or versatility
If a detachable connector is introduced between feeder wire and waveguide cable, then connection flexibility is improved, but device complexity increases
Solution Approach 1:
The detachable connector is segmented into two separate units fixed to different components (circuit board and waveguide cable). This segmentation distributes the complexity across two simple fixed units rather than one complex detachable unit, reducing overall device complexity while maintaining connection flexibility.
4Ease of operation
If the connector is made detachable for easy connection and disconnection, then ease of operation is improved, but connection reliability may deteriorate
Solution Approach 1:
The connector is segmented into a first unit fixed to the circuit board and a second unit detachably coupled to the waveguide cable. The fixed first unit ensures reliable signal transmission from the circuit board, while the detachable second unit provides ease of operation for cable connection and disconnection without compromising overall reliability.
