Boat Stabilizer Fin with Integrated Watertight Compartment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-roll and anti-pitching stabilizers for marine vehicles are rigid, difficult to adapt, complex to install, and prone to high failure rates due to exposure to aggressive environments, leading to increased costs and reduced durability.
Innovation Solution
A stabilizer system featuring a fin with an integrated engine and kinematic chain housed within a watertight compartment, allowing for 360-degree rotation and controlled by oscillation sensors and a control device to dampen roll and pitch oscillations, with components sealed to prevent water ingress and minimize exposure to harsh conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the engine and kinematic chain are located externally to the hull, then the stabilizer can be assembled, but the components are subject to rapid wear and high failure rates due to the aggressive chemical environment
Solution Approach 1:
The engine and kinematic chain are nested inside the watertight compartment formed by the fin structure. The fin itself forms a hollow compartment that houses all mechanical components, protecting them from the aggressive marine environment while maintaining a compact integrated design.
Solution Approach 2:
A watertight compartment acts as an intermediary barrier between the aggressive marine environment and the sensitive mechanical components. This sealed enclosure prevents direct contact between saltwater and the engine/kinematic chain, reducing corrosion and failure rates.
2Reliability
If the engine is housed inside the hull, then the stabilizer is protected from the aggressive environment, but the free space inside the boat is reduced
Solution Approach 1:
The engine and kinematic chain are placed in a third dimension - inside the hollow compartment formed by the fin structure itself. This vertical integration into the fin's internal volume eliminates the need for additional hull space, as the fin's own structure provides the housing.
3Device complexity
If the kinematic chain and engine are exposed to the aggressive atmosphere, then the design is simpler, but the failure rate increases due to rapid wear
Solution Approach 1:
The protective compartment, engine mounting structure, and kinematic chain support elements are merged into a single integrated fin assembly. This consolidation means the same structural components that provide mechanical function also provide environmental protection, eliminating the need for separate protective housings.
