Rotatable Jet Discharge Port for Boat Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jet propulsion boats face delays in steering due to fixed discharge ports, requiring complex valve control and multiple ports with different directions, which complicates user operation and increases the number of components.
Innovation Solution
A jet propulsion boat design featuring a rotatable second discharge portion that can change its discharge direction, reducing the need for multiple fixed ports and simplifying control, with a 360-degree rotation capability and automatic direction adjustment using a drive source, allowing for intuitive user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple fixed discharge ports are provided with different discharge directions, then the boat can be steered in different directions, but the device complexity and number of components increase
Solution Approach 1:
The patent applies the dynamics principle by making the discharge port rotatable rather than fixed. The discharge port can rotate to change its discharge direction dynamically, allowing the boat to steer in different directions without requiring multiple fixed discharge ports. This reduces the number of components while maintaining steering capability.
2Adaptability or versatility
If multiple fixed discharge ports are provided with different discharge directions, then the boat can be steered in different directions, but the control mechanism becomes more complex
Solution Approach 1:
The discharge port is designed to rotate and change its discharge direction dynamically based on steering requirements. This dynamic adjustment eliminates the need for complex control mechanisms that would be required to manage multiple fixed discharge ports with different directions.
3Speed
If the discharge direction is changed by rotating the discharge port, then steering responsiveness is improved, but the device complexity increases
Solution Approach 1:
The discharge port is designed to rotate and change its discharge direction dynamically based on steering requirements. This dynamic adjustment eliminates the need for complex control mechanisms that would be required to manage multiple fixed discharge ports with different directions.
