Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional marine craft with water-based propulsion and control surfaces become insufficient at high speeds, leading to safety and comfort issues, especially in rough seas, as they lose propulsion when out of the water and lack effective maneuverability.
Innovation Solution
An airboat with air-based propulsion and aircraft-like three-axis control surfaces, featuring a triangular hull with a concave bottom for stability and surface adhesion, and retractable water rudders for enhanced traction and control, allowing safe high-speed navigation over waves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If water-based propulsion and control surfaces are used in marine craft, then the craft can operate effectively at low speeds, but the craft loses propulsion and maneuverability at high speeds when out of the water
Solution Approach 1:
The patent changes the medium of propulsion from water to air. The air-based propulsion system uses air jets or propellers that can operate effectively both when the craft is in water and when it is out of the water, maintaining propulsion reliability across the full speed range including high-speed operation
Solution Approach 2:
The patent employs retractable water rudders that can be extended when needed for water-based maneuvering and retracted when operating at high speeds or out of water. This dynamic configuration allows the control system to adapt to different operating conditions, maintaining effectiveness across varying speeds and water contact states
2Speed
If conventional water-based control surfaces are used, then the craft can maneuver at low speeds, but the craft lacks effective maneuverability and safety control at high speeds
Solution Approach 1:
The patent introduces air-based control surfaces (air rudders, elevators, and ailerons) that operate using air pressure differentials. These control surfaces remain effective at high speeds where water-based surfaces would be insufficient, providing continued maneuverability and safety control across the entire speed range
Solution Approach 2:
The patent implements a hybrid control system that includes both water-based rudders and air-based control surfaces. This multi-functional control system can operate effectively in both water-contact and air-contact conditions, providing universal maneuverability capability across different speed regimes and sea states
3Adaptability or versatility
If a square-shaped bow is used in airboats, then the craft can navigate through marshland effectively, but the craft is not suitable for high speed marine operation
Solution Approach 1:
The patent employs an asymmetric hull design with a V-shaped or rounded bow rather than a square bow. This asymmetric shape reduces wave resistance and improves hydrodynamic performance at high speeds while maintaining the ability to navigate shallow and varied water conditions, thus achieving both speed and adaptability
4Stability of the object's composition
If a flat bottom hull is used in marine craft, then the craft can provide stability, but the craft cannot achieve efficient hydroplaning at high speeds
Solution Approach 1:
The patent uses a V-shaped or rounded hull bottom instead of a flat bottom. This curved geometry allows the hull to cut through waves more efficiently, reduce slamming impacts, and achieve better hydroplaning characteristics at high speeds while maintaining stability through proper center of gravity positioning and hull form
