Solution Overview

Problem

Existing wave-powered generation systems face inefficiencies due to limitations in harnessing both sides of the wave curve, low energy conversion rates, and inability to withstand adverse weather conditions, with most technologies relying on air or water as working mediums that are not compressible, leading to suboptimal energy extraction and storage.

Innovation Solution

A wave-powered generator that uses air as a compressible medium, employing a bi-directional pumping mechanism to capture both sides of the wave curve's energy, with a larger piston acting as a float and a smaller piston inside a stationary cylinder to amplify pressure, allowing continuous energy storage and regulation without interruptions.

VSEngineering Contradiction Analysis

1Ease of manufacture

If air or water is used as working medium in wave-powered systems, then the system can operate with simple mechanics, but the energy extraction efficiency is limited because these mediums are not compressible

Engineering Contradiction:
Improvesystem simplicityVSAvoidenergy extraction efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent employs a pneumatic compressor system where wave motion drives pistons to compress air into storage tanks. This transforms the mechanical wave energy into compressed air potential energy, overcoming the limitation of non-compressible working mediums while maintaining mechanical simplicity in the wave-to-compression transformation process.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Device complexity

If only one side of the wave curve is utilized for energy generation, then the system design is simpler, but the energy output is reduced by approximately half

Engineering Contradiction:
Improvesystem design complexityVSAvoidenergy output
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent implements a dual-action piston system where both the upward and downward movements of waves are utilized. The piston compresses air during one direction of wave motion and allows expansion during the opposite direction, ensuring continuous useful action throughout the entire wave cycle rather than utilizing only half the wave energy.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system dynamically adapts to wave direction changes by using bidirectional pistons that automatically switch between compression and expansion modes. This dynamic response allows the system to capture energy from both crests and troughs of waves, doubling the effective energy capture compared to unidirectional systems.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If pressure is increased to improve energy density, then the energy storage capacity increases, but the system requires more complex compression mechanisms and higher safety requirements

Engineering Contradiction:
Improveenergy storage capacityVSAvoidcompression mechanism complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The wave-powered compressor system is self-regulating, using the natural force of waves to drive the compression process. The system requires no external power source or complex control mechanisms - the wave energy itself provides the driving force, and the compression level is naturally regulated by the wave intensity and piston design.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Air serves as an intermediary medium that stores the mechanical energy from waves in compressed form. This gaseous intermediary allows for dense energy storage while maintaining simple mechanical compression through piston movement, avoiding the need for complex high-pressure containment systems that would be required with liquid or solid energy storage methods.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If wave energy systems are designed to withstand adverse weather conditions, then the reliability improves, but the structural complexity and cost increase significantly

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs flexible, buoyant structures that can naturally adapt to wave forces rather than rigid structures that must resist them. The floating components and pneumatic elements are designed to flex and move with adverse weather conditions, maintaining operational reliability without requiring heavy reinforcement or complex stabilization systems.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

A machine and process to compress ambient air using natural swell of ocean waves to store energy. The devise is a bi-directional air pump operated by ocean wave power of water buoyancy as well as earth gravity in a pressure vessel using a piston. The machine uses a large surface area as float connected by a rod to a small area as piston, housed in a pressure vessel to multiply compression of air. The compression of air is directly proportional to the respective surface areas of float to the piston attached with a rod inside the pressure vessel. An array of similar machines can be employed to multiply potential energy output.
