Solution Overview

Problem

Existing paddle-wheel propelling mechanisms for boats lack effective power transmission, maneuverability, and the ability to navigate in shallow waters.

Innovation Solution

A steerable and retractable paddle-wheel propulsion and steering mechanism is designed, comprising a frame structure, a propulsion mechanism with a central drive shaft and side drive shafts, a paddle-wheel upward and downward moving mechanism, and a steering mechanism, allowing for compact installation on various boat types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If a traditional paddle-wheel mechanism is used, then the structure is simple, but the power transmission efficiency is poor

Engineering Contradiction:
Improvepower transmission efficiencyVSAvoidmechanism structure complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The paddle wheel is designed to be retractable, allowing it to dynamically adjust its position between engaged and disengaged states. This dynamic capability enables efficient power transmission when engaged while maintaining operational flexibility when disengaged, resolving the contradiction between power transmission efficiency and operational versatility

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the paddle wheel is fixed in position, then the power transmission is stable, but the maneuverability and ability to navigate shallow waters is reduced

Engineering Contradiction:
ImprovemaneuverabilityVSAvoidpower transmission stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The retractable paddle wheel mechanism allows the paddle wheel to be dynamically positioned - engaged for stable power transmission during cruising, and disengaged/retracted for maneuvering or navigating shallow waters. This dynamic adaptability resolves the contradiction between maneuverability and power transmission stability

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the paddle wheel is always engaged with the drive shaft, then the power transmission is continuous, but the ability to navigate shallow waters and maneuver is limited

Engineering Contradiction:
Improveability to navigate different water conditionsVSAvoidpower transmission continuity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The mechanism enables dynamic engagement and disengagement of the paddle wheel with the drive shaft. The paddle wheel can be retracted when continuous power transmission is not needed (such as during maneuvering or in shallow waters), and engaged when continuous propulsion is required, thus resolving the contradiction between adaptability and power transmission continuity

Inventive Principle:
Principle #15Dynamics
