Cryogenic Connector Latch and Sensor for Secure Probe Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cryogenic systems face challenges in connecting and disconnecting entities such as probes and Dewars while maintaining insulation and sealing to prevent cryogen evaporation and exposure.
Innovation Solution
A cryogenic connector system with a latch plate that slides between positions to securely insert a plug or a cryogenic probe, and a sensor to control cryogen flow based on the latch plate's position, ensuring safe and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connector allows easy connection and disconnection of cryogenic entities, then the ease of operation is improved, but the risk of inadvertent removal increases
Solution Approach 1:
The connector employs a dynamic latch plate that can slide between positions to engage or disengage the connection. The latch plate moves from a first position (engaged with the groove) to a second position (disengaged), providing controlled connection and disconnection while preventing accidental removal through its locked engaged state
Solution Approach 2:
The sensor detects the position of the latch plate and provides feedback to control the cryogen flow. When the latch plate is in the engaged position, the sensor confirms proper connection before allowing cryogen flow, ensuring reliability while maintaining ease of operation
2Loss of substance
If a connector provides secure sealing and insulation to prevent cryogen evaporation, then the loss of substance is reduced, but the device complexity increases
Solution Approach 1:
The connector is divided into distinct functional segments: the connector base plate for structural support and connection, the latch plate for securing, the groove for positioning, and the sensor for detection. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity
Solution Approach 2:
The connector design allows the latch plate to automatically engage with the groove when the plug or probe is inserted, providing self-latching functionality. The sensor automatically detects the engaged position and controls cryogen flow accordingly, reducing the need for additional control mechanisms

AI summary
Cryogenic apparatus, consisting of a connector that has a connector base plate configured for connection to a conduit carrying a cryogen, and a slot extending across the base plate. The apparatus has a plug, which is configured for insertion into an opening in the base plate. The apparatus also has a latch plate that is configured to slide within the slot between a first position, in which the plug is inserted through an aperture in the latch plate into the opening, and a second position, in which a cryogenic probe is inserted through the aperture and brought into fluid communication with the opening. There is a sensor, which is coupled to control a flow of the cryogen through the conduit by detecting whether the latch plate is in the first position or the second position.
