Solution Overview
Problem
Conventional shipping technologies, such as diesel engines, are inefficient in reducing fuel consumption and pollutant emissions, and existing sail rotor technologies are not seaworthy for large cargo ships in high seas conditions.
Innovation Solution
A ship design incorporating multiple sail rotors and an electric motor-driven propeller, with a pivoting fore ship plate that adjusts to break waves and optimize wind flow for maximum Magnus propulsion, ensuring safe operation in rough seas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the foreship has a fixed structure, then the ship structure is simple and stable, but waves hitting the foreship penetrate the ship in heavy seas
Solution Approach 1:
The patent applies the dynamics principle by making the foreship plate movable rather than fixed. The plate can pivot between an upper position for normal operation and a lower position for wave breaking, allowing the structure to adapt dynamically to sea conditions. This resolves the contradiction by providing both structural simplicity (when in fixed upper position) and seaworthiness (when pivoted to lower position for wave breaking).
2Reliability
If the plate is positioned to break waves, then seaworthiness is improved, but wind flow to the sail rotors is disrupted
Solution Approach 1:
The movable plate allows dynamic adjustment between wave-breaking configuration and wind-flow optimization configuration. When sea state is calm, the plate is positioned to maximize wind flow to the Magnus rotors for efficient propulsion. When heavy seas occur, the plate pivots to break waves, temporarily sacrificing wind flow for safety. This dynamic adaptability resolves the contradiction between seaworthiness and energy utilization.
Solution Approach 2:
The plate operates periodically, alternating between wave-breaking mode during storm conditions and wind-capture mode during calm conditions. This periodic switching between conflicting functional states allows the system to optimize for seaworthiness when needed and for energy efficiency when conditions permit, resolving the contradiction through time-based separation of functions.
3Use of energy by moving object
If sail rotor technology is used, then fuel consumption is reduced, but the ship is not seaworthy in high seas
Solution Approach 1:
The patent segments the ship into distinct functional zones: the movable foreship plate for wave breaking, the bridge area for navigation, and the Magnus rotor area for propulsion. This segmentation allows each zone to be optimized independently - the foreship plate handles wave breaking to protect seaworthiness, while the Magnus rotors continue to provide fuel-efficient propulsion, resolving the contradiction between energy efficiency and seaworthiness.
Solution Approach 2:
The movable foreship plate acts as an intermediary element between the ocean waves and the ship's propulsion system. It absorbs and breaks incoming waves, preventing them from reaching the Magnus rotors and disrupting their operation. This intermediary protects the fuel-efficient propulsion system while maintaining seaworthiness, resolving the contradiction between using sail rotor technology and ensuring seaworthiness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design reduces fuel consumption and emissions by harnessing wind energy efficiently while maintaining seaworthiness, effectively breaking waves and directing wind for optimal propulsion, even in harsh sea conditions.
Implementation Method 1
A sail rotor is a rotating cylinder mounted on a ship, powered by an engine, preferably an electric motor, which generates thrust in conjunction with the passing wind. The physics of these sail rotors was already described by the physicist Magnus
Implementation Method 2
when heavy seas and thus strong waves are present, the plate can be pivoted downwards and waves hitting the foreship are then broken and the water penetrating can flow off to the side without penetrating the ship
