Maritime Vessel Stabilizer With Extendable Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maritime vessels face stability challenges due to surface wave action, which hampers the use of weapons systems and requires more sophisticated navigation and targeting systems, especially for military vessels.
Innovation Solution
A stabilization system for maritime vessels that includes a stabilizer module with an extendable body and actuator, allowing movement between a first position adjacent to the housing and a second position below the vessel, combined with thrusters and a gyroscopic stabilizer to provide dynamic and passive stabilization, lowering the center of mass relative to the center of buoyancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If no stabilizer is used, then the device complexity is low, but the stability of the maritime vessel deteriorates under surface wave action
Solution Approach 1:
The stabilizer system employs dynamic components including an extendable body that can move between retracted and extended positions, and thrusters that provide active stabilization forces. The system transitions from a static structure to a dynamically adjustable configuration that adapts to varying sea conditions, resolving the contradiction between simplicity and stability.
Solution Approach 2:
The stabilizer system is divided into modular components: a stabilizer housing, an extendable body with thrusters, and a control system. This segmentation allows the complex stabilization function to be achieved through coordinated operation of simpler, independent modules, making the overall system more manageable while providing effective stability.
2Stability of the object's composition
If sophisticated weapons systems with advanced navigation and targeting are used, then the stability requirement is met, but the cost and device complexity increase
Solution Approach 1:
The stabilizer system extracts and addresses the stability problem separately from the weapons system. By providing dedicated stabilization through the extendable body and thrusters, the complex weapons and targeting systems no longer need to incorporate their own stabilization mechanisms, reducing overall system complexity and cost.
3Stability of the object's composition
If the extendable body is positioned below the vessel for stabilization, then the stability improves, but the device complexity and space requirements increase
Solution Approach 1:
The extendable body is nested within the stabilizer housing when in the retracted position, and extends outward when stabilization is needed. This nesting arrangement minimizes the space requirements and reduces the visual and structural complexity of the system when the stabilizer is not actively deployed.

AI summary
A stabilization system for a maritime vessel including a stabilizer module. The stabilizer module includes a stabilizer housing and an extendable body. An extension feature couples the extendable body with the stabilizer housing. The extension feature is configured to allow movement of the extendable body between a first position adjacent to the stabilizer housing and a second position separated from the stabilizer housing below the maritime vessel. An actuator is provided for moving the extendable body between the first position and the second position.
