Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for generating electricity from water, such as those using tidal or river flow, are inefficient and contribute excessive drag to boats, and lack a practical means to recharge batteries or provide continuous power when boats are in motion or at anchor.
Innovation Solution
A compact electrical generating system utilizing a paddle wheel connected to a generator, where the paddle wheel is mounted on the back or side of a boat, or attached to a dock, and is connected through a series of pulleys and gears to an alternator inside the boat, allowing kinetic energy from slow-moving water to be converted into electrical energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a water wheel system is used to generate electricity on boats, then continuous power can be provided without gasoline engines, but the system increases drag on the boat
Solution Approach 1:
The water wheel is divided into multiple paddle segments that can independently interact with water flow. This segmentation allows the wheel to generate power from slower water currents more efficiently, reducing the need for a large wheel diameter and thus minimizing drag on the boat while maintaining continuous power generation capability.
Solution Approach 2:
The patent positions the water wheel in a three-dimensional space optimized for minimal drag, mounting it on the stern or side of the boat rather than in the center. The wheel is positioned to engage water flow in a direction perpendicular to the boat's main axis of motion, allowing power generation without significantly increasing forward drag.
2Adaptability or versatility
If a compact electrical generating system is used, then the system can be installed on various vessels, but the power generation capacity is limited
Solution Approach 1:
The electrical generating system is designed with universal mounting configurations that can be adapted to different boat sizes and types. The water wheel, pulley system, and generator are configured as a modular assembly that can be installed on small recreational boats, medium-sized vessels, or even stationary dock installations, providing versatile power generation across multiple applications.
Solution Approach 2:
The system employs composite construction methods where the water wheel combines lightweight materials for the wheel structure with durable materials for the paddles. This composite approach maximizes power generation capacity within compact dimensions, allowing the system to fit on smaller vessels while maintaining adequate power output for onboard electrical systems.
3Speed
If a paddle wheel with pulleys and gears is used to convert kinetic energy, then electricity can be generated from slow-moving water, but the device complexity increases
Solution Approach 1:
The patent replaces complex multi-stage gear reduction systems with a direct-drive pulley-belt configuration. The water wheel is directly connected to the generator through a simple pulley and belt system, eliminating the need for multiple gear stages. This substitution maintains the ability to extract energy from slow-moving water while significantly reducing mechanical complexity and the number of moving parts.
Solution Approach 2:
The invention extracts only the essential mechanical components needed for energy conversion, removing unnecessary intermediate gears and complex transmission mechanisms. The system uses a simplified chain of pulleys and belts that directly transfer rotational energy from the water wheel to the generator, maintaining effectiveness with slow water flow while minimizing device complexity.

AI summary
There is provided a power generating system to recharge the batteries of a boat as the boat moves under power through a body of water. The electrical generating system has a relatively large water wheel connected to a boat. As the boat moves through the water, the water wheel turns producing energy and, through a series of pulleys and wheel gears and then to a generator or alternator and then the electrical energy is passed to a battery. The water wheel may be mounted on the stern of the boat, or to the side of the boat, or in a cut out portion in the bottom of the boat.
