Tool-Less Bulkhead Connector for Watertight AUV Module Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for connecting modules in autonomous underwater vehicles (AUVs) are inefficient, requiring specialized tools and equipment, and do not provide a rapid, flexible, and watertight electrical connection.
Innovation Solution
A bulkhead connector system with self-indexing guides and slots, latches, and over-center levers allows modules to be coupled and uncoupled rapidly without tools, ensuring watertight seals and electrical communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional connecting methods are used for AUV modules, then electrical connection between modules can be achieved, but the connection process requires specialized tools and equipment, reducing operational efficiency
Solution Approach 1:
The bulkhead connector is designed to be self-aligning through guide rails and slots that automatically position the connector plugs upon insertion. The over-center latch mechanism automatically secures the connection without requiring external tools or equipment, enabling operators to complete module connections quickly and independently
Solution Approach 2:
The connector is divided into distinct functional components: guide rails for alignment, slots for plug reception, recesses for securing plugs, and over-center latches for locking. This segmentation allows each component to perform its specific function independently, simplifying the overall connection process and eliminating the need for complex tooling
2Adaptability or versatility
If modules are designed for rapid reconfiguration, then flexibility and adaptability improve, but ensuring watertight seals during quick connections becomes more difficult
Solution Approach 1:
The guide rails and slots are pre-configured with precise geometries that automatically align the connector plugs with the correct insertion position before contact is made. This preliminary alignment action ensures that seals are properly positioned and engaged from the moment modules begin to connect, maintaining watertight integrity throughout the rapid reconfiguration process
Solution Approach 2:
The guide rails and slots act as intermediary elements between the connector plugs and the mating interface. These intermediaries guide the plugs along a predetermined path, ensuring proper positioning and seal engagement before the final locked connection is achieved, thereby preserving watertight seals during rapid connections
3Ease of repair
If tool-free quick release mechanisms are implemented, then ease of maintenance improves, but the complexity of the latching system increases
Solution Approach 1:
The over-center latch mechanism is designed to be manually operated and extracted from the bulkhead connector assembly. This allows the latching function to be separated from the bulkhead structure, simplifying maintenance by enabling the latch to be removed and replaced independently if needed, while still providing secure connections during operation
Solution Approach 2:
The over-center latch mechanism utilizes dynamic mechanical advantage through its cam-shaped lever. When the lever is actuated, it automatically transitions from an open position to a locked position through the over-center action, providing secure latching without requiring complex control systems or multiple components. The dynamic action simplifies the overall system while maintaining reliability

AI summary
This disclosure describes systems, and methods for bulkhead connectors, systems, and methods for coupling modules together to form an electrical connection between watertight modules. The bulkhead can include a first face comprising a first guide rail; a second face, parallel to the first face and defining a first slot shaped to receive a second guide rail; a third face, perpendicular to the first face and the second face, the third face defining a first recess configured to receive a first connector plug; and a coupling configured to affix the bulkhead to a hull.
