Retractable Lateral Wing for High Speed Ship Boost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high-speed ocean-going ships face challenges in achieving and maintaining a planing state efficiently, especially when fully loaded, due to insufficient cruise power and drag-related inefficiencies, limiting their speed and operational capacity.
Innovation Solution
The implementation of a boost phase assist structure and/or load shift mechanism, including a retractable lateral wing structure with auxiliary power, to assist in achieving and maintaining a planing state, which can provide power, lift, and hydrodynamic trim, allowing the vessel to transition from a slip stream to a planing state and reduce drag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a vessel uses conventional cruise power to achieve planing state, then the structure remains simple, but the vessel cannot achieve planing state efficiently when fully loaded
Solution Approach 1:
The patent applies preliminary action by using a boost power system to achieve planing state before the main cruise power is engaged. The boost power system provides additional thrust during the transition phase, enabling the vessel to reach planing speed more effectively when fully loaded, after which the main cruise power maintains the planing state with minimal energy consumption.
2Productivity
If the vessel operates at high speed continuously, then productivity increases, but power consumption increases
Solution Approach 1:
The patent applies periodic action by using the boost power system only during the transition to planing state and then disengaging it during cruise operation. This periodic engagement of additional power only when needed for state transition, rather than continuous operation, maintains high productivity while minimizing overall power consumption during the cruise phase.
3Speed
If the vessel uses sufficient power to achieve planing state when fully loaded, then speed is improved, but the cruise power source becomes oversized
Solution Approach 1:
The patent applies segmentation by dividing the power system into two distinct components: a boost power system for achieving planing state and a main cruise power system for maintaining it. This segmentation allows each system to be optimized for its specific function, preventing the cruise power source from being oversized while ensuring sufficient power availability during the critical transition phase.
