Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Seaplanes face difficulties in maneuvering on water due to propeller-based directional control, which can be dangerous and difficult in marina environments, especially with wind disturbances and loss of directional control.
Innovation Solution
A seaplane propulsion system with independently operable first and second float members, each equipped with a propulsion assembly that provides forward and rearward thrust, utilizing impellers or similar elements to maneuver without propeller assistance, controlled by a system within the aircraft cabin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If propeller-based directional control is used, then the seaplane can achieve forward propulsion, but it loses directional control and creates safety risks in marina environments
Solution Approach 1:
The propulsion system is segmented into multiple independent float members (first float member and second float member), each equipped with its own propulsion assembly. This segmentation allows independent control of each float, enabling precise directional manipulation without relying on a single propeller, thereby improving safety and control reliability in marina environments.
Solution Approach 2:
Instead of using a propeller to push water backward for forward motion, the invention inverts the approach by using impellers mounted on floats to push water backward directly from the float structure. This inversion allows the float itself to become the propulsion element, providing direct control over water interaction and improving directional control safety.
2Productivity
If the propeller is used for maneuvering, then the seaplane can move forward, but it creates wind disturbances that negatively impact boats in the marina
Solution Approach 1:
The harmful propeller is extracted from the traditional seaplane configuration and replaced with float-mounted propulsion assemblies. By removing the large rotating propeller that generates wind disturbances, the invention eliminates the harmful effect on surrounding boats while retaining maneuvering capability through the float-based impeller system.
3Speed
If the seaplane gains momentum and sails into a dock, then it can reach the destination, but it loses directional control and increases accident risk
Solution Approach 1:
The propulsion system transitions from a fixed propeller configuration to a dynamic float-based system where the orientation and thrust direction of each float can be independently adjusted. This dynamic control allows the pilot to maintain directional control at all times, preventing the loss of control that occurs when sailing into docks at high speed.
