Solution Overview

Problem

The challenge of energy storage and availability in renewable energy systems, such as photovoltaic and wind power, limits their ability to provide energy independently and efficiently match demand, especially in domestic and local community settings, where energy surplus is often fed into the grid and not stored for later use.

Innovation Solution

A mini hydroelectric power station is proposed, incorporating a storage reservoir, penstock, and a turbine connected to a generator, with a water supply system driven by an autonomous and ecological energy source, utilizing a large-diameter toothed wheel with containers to efficiently transport water from a recovery tank to a storage tank, allowing for on-demand energy use and irrigation integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If renewable energy sources (photovoltaic, wind) are used for electricity generation, then energy production is environmentally friendly and non-polluting, but energy storage and availability according to demand are difficult or impossible

Engineering Contradiction:
ImproveCO2 emissionVSAvoidenergy storage and availability
Core Design Contradiction:
Object-generated harmful factorsVSReliability

Solution Approach 1:

The patent applies hydraulic principles by using water as the working fluid to store and transfer energy. The hydroelectric power plant converts gravitational potential energy of stored water into electrical energy through a turbine, providing reliable on-demand power while maintaining environmental friendliness. This hydraulic energy storage system resolves the contradiction by enabling both clean energy generation and dependable energy availability.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Adaptability or versatility

If renewable energy installations are connected to the general electricity network, then excess energy can be resold and energy shortage compensated, but complete energy independence is lost and high distributor costs cannot be negotiated

Engineering Contradiction:
Improveenergy exchange with networkVSAvoidenergy independence
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements preliminary action by storing energy in the form of elevated water in a storage tank during periods of excess renewable energy production. This pre-stored hydraulic energy can then be converted to electricity on-demand through the hydroelectric turbine, eliminating the need for grid connection and ensuring complete energy independence. The system prepares energy in advance for later autonomous use.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If small power plants are built to supply electricity to districts or small industrial establishments, then local energy production increases, but the problem of energy storage and availability according to current consumption remains unsolved

Engineering Contradiction:
Improvelocal energy productionVSAvoidenergy storage and availability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent achieves universality by designing a small-scale hydroelectric power plant that can serve multiple functions: generating electricity for local consumption, storing energy in the elevated water tank for later use, and potentially providing irrigation water through the penstock system. This multi-functional system simultaneously addresses local energy production needs and energy storage/availability reliability.
