Solution Overview

Problem

Current rotational energy storage methods, such as flywheels and waterwheels, face limitations in increasing energy storage capacity due to the need for high mass and velocity, which requires expensive materials and safety measures, and water-powered generators inefficiently use water for energy transfer without maximizing mass storage.

Innovation Solution

A fluid flywheel device that retains and increases the rotational velocity of contained liquid by positioning the outlet above the inlet, allowing continuous energy input to maintain rotation and extract mechanical energy through a rotating shaft, reducing the need for high initial mass and using liquid as both mass and motive force.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If water wheels are used to store rotational energy, then energy storage capacity increases, but the mass of the wheel must be increased linearly which requires more energy to start motion and reduces system efficiency

Engineering Contradiction:
ImprovemassVSAvoidenergy to start motion
Core Design Contradiction:
Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The patent uses hydraulic principles by allowing water to flow through the wheel continuously, using the water's own kinetic energy to keep the wheel rotating rather than relying solely on initial mechanical energy. The water flow provides continuous energy input that maintains rotation without requiring excessive initial mass or startup energy.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The patent transitions from a static mass-based energy storage system to a dynamic system where water continuously flows through the wheel. This dynamic approach allows the system to maintain rotation through continuous energy input from water flow rather than relying on large static mass that requires significant energy to initiate motion.

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If flywheels spin at extremely high RPMs to increase energy storage, then rotational energy increases with velocity squared, but expensive composite materials, magnetic bearings, vacuum chambers and safety measures are required

Engineering Contradiction:
Improverotational energyVSAvoidmaterials and safety measures
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent employs hydraulic energy transfer where water flow provides the rotational energy instead of using high-speed rotating masses. This approach achieves energy storage through water's kinetic energy and continuous flow rather than through high-RPM flywheels that require expensive materials and complex safety systems.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The patent substitutes the traditional mechanical flywheel system with a hydraulic system where water flow drives the wheel. This replacement eliminates the need for high-RPM mechanical rotation and the associated expensive composite materials, magnetic bearings, and vacuum chambers while maintaining energy storage capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Power

If water flows through a vortex shaped container once in water powered generators, then energy transfer occurs, but the water is not retained to increase available mass for storing rotational energy

Engineering Contradiction:
Improveenergy transferVSAvoidmass for storage
Core Design Contradiction:
PowerVSQuantity of substance

Solution Approach 1:

The patent implements continuous water circulation where water flows through the wheel and is retained in the system, continuously providing both energy transfer and mass for rotational energy storage. The water does not exit after a single pass but circulates continuously, maintaining both power generation and energy storage functions simultaneously.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent makes the water serve dual functions: it provides kinetic energy for power generation while simultaneously acting as the rotating mass for energy storage. This multi-functional use of water eliminates the need for separate energy transfer and storage systems, as the same water mass performs both roles.

Inventive Principle:
Principle #6Universality (Multi-functionality)
