Pin Array Chamber for UMV Capture and Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current launch and recovery systems for unmanned maritime vehicles (UMVs) face challenges with high-speed capture without destruction, requiring complex operations, low cycle rates, and structural modifications, due to constraints in relative positioning, timing, hydrodynamic interference, and structural issues.
Innovation Solution
The Pin Array Chambering System (PACS) uses a pin array mechanism to provide non-destructive clamping and release of moving objects, allowing for high-cycle rates and efficient capture and release without structural modifications to either the host or the UMV, applicable in various environments including water, air, and space.

Engineering Contradiction Analysis
1Reliability
If netting and hooking solutions are used for UMV recovery, then capture capability is improved, but UMV may be harmed or destroyed in the process
Solution Approach 1:
The capture system is segmented into multiple independent pins arranged in arrays on opposing surfaces. Instead of using a single net or hook that contacts the entire UMV, the system uses numerous discrete pins that individually engage with the UMV surface, distributing the capture forces and reducing localized damage while maintaining reliable capture capability.
Solution Approach 2:
The pin array system applies localized contact forces at specific points on the UMV surface rather than distributed contact across the entire vehicle. This localized engagement allows precise control of capture forces at each pin location, enabling reliable capture while minimizing overall damage to the UMV structure.
2Reliability
If complex launch and recovery operations are performed with mother ship, then capture reliability is improved, but cycle rate decreases and operational complexity increases
Solution Approach 1:
The recovery system is divided into independent pin arrays that can operate autonomously without requiring complex coordination between multiple ship systems. Each pin array functions independently to capture and release UMVs, simplifying the overall operational sequence and enabling faster cycle rates while maintaining reliable capture.
Solution Approach 2:
The pin arrays are pre-positioned and pre-configured on the mother ship before UMV approach. This preliminary preparation eliminates the need for complex real-time adjustments during capture operations, allowing faster recovery cycles while ensuring reliable capture through pre-optimized pin placement and configuration.
3Reliability
If traditional launch and recovery systems are used, then capture function is achieved, but device complexity and weight increase
Solution Approach 1:
The capture system is segmented into simple pin arrays mounted on opposing surfaces, eliminating the need for complex mechanical linkages, hydraulic systems, or control mechanisms found in traditional launch and recovery systems. Each pin operates independently, reducing overall system complexity while maintaining effective capture function.
Solution Approach 2:
The pin array system is designed to automatically engage and disengage UMVs without requiring complex external control systems. The pins self-adjust during the capture process, and the system can autonomously complete the recovery operation, significantly reducing the complexity of control mechanisms and associated equipment.

AI summary
An unmanned maritime vehicle (UMV) pin array release and capture chamber system includes a chamber assembly having two parallel plates of pin arrays from which a plurality of pins extends and retract vertically opposite each other so as to release and capture a UMV. The pin arrays are separated from each other by a space having two vertical and two horizontal sides, and the space is sized so as to receive the UMV. Each pin arrays may be housed in a pin array chamber enclosure. The chamber assembly may be attached to a moving object, such as a naval vessel, above or below the surface of water, or may be stationary with respect to the water movement, or may be stationary with respect to the ground such as a pier.
