Solution Overview

Problem

Current heating and cooling methods in residences and buildings rely heavily on fossil fuels, leading to air pollution and high energy consumption, with heating water being a significant energy user and air conditioners contributing to carbon dioxide emissions.

Innovation Solution

A zero-fossil-fuel-using apparatus that utilizes the sun's heat and subsurface ground coolness, transferred through water pipes using gravity and garden hose pressure, to provide heating and cooling, and a steam-powered electricity generator to produce electricity during daylight hours with battery charging for nighttime use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If fossil fuels are used for heating and cooling residences, then heating and cooling can be provided, but air pollution and carbon dioxide emissions increase

Engineering Contradiction:
Improveair pollutionVSAvoidheating and cooling capability
Core Design Contradiction:
Object-affected harmful factorsVSUse of energy by moving object

Solution Approach 1:

The patent replaces the mechanical combustion system (fossil fuel burning) with a thermal system that uses solar energy concentration and subsurface heat exchange. The solar collector with magnifying lenses concentrates sunlight to heat water, while the subsurface heat exchanger uses natural ground temperature for cooling, eliminating the need for combustion engines and reducing air pollution.

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

Solution Approach 2:

The patent introduces water as an intermediary medium to transfer thermal energy. Water is heated by the solar collector and circulated through piping to provide heating, and similarly, water is cooled by the subsurface heat exchanger for cooling purposes. This intermediary approach replaces direct fossil fuel combustion with a cleaner thermal transfer mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Use of energy by moving object

If fossil fuels are used for heating water, then hot water can be provided, but energy consumption increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidhot water supply
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The solar water heating system is designed to be self-service by using passive thermal convection and gravity-driven circulation. The heated water naturally rises and circulates through the piping system without requiring additional energy input for pumping, making the hot water supply system self-sustaining and energy-efficient.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If air conditioners are used for cooling residences, then cooling can be provided, but carbon dioxide emissions increase

Engineering Contradiction:
Improvecarbon dioxide emissionsVSAvoidcooling capability
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The patent converts the naturally warm subsurface ground (which would normally be a source of heat gain in summer) into a beneficial cooling resource. By placing heat exchanger pipes in the subsurface, the system exploits the relatively cooler ground temperature at depth to absorb heat from circulating water, providing natural cooling without carbon dioxide emissions.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Device complexity

If pumps are used to circulate water for heat transfer, then heat distribution can be improved, but device complexity and energy consumption increase

Engineering Contradiction:
Improvesystem complexityVSAvoidenergy consumption
Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

The system is designed to operate at equipotential conditions where water circulation is driven by natural convection currents and gravity rather than mechanical pumps. The heated water rises naturally due to buoyancy, and the cooling system uses gravity-driven flow, eliminating the need for energy-consuming pumping equipment and simplifying the overall system.

Inventive Principle:
Principle #12Equipotentiality

AI summary

The invention provides an apparatus which can heat water using a Fresnel lens or magnifying glass to focus and concentrate sunlight on water-filled radiator-like tubes which move water, by the water pressure from a water spigot/bib (without pumping), to: (1) move the heated water through tubes to heat any space inside any building, and (2) provide steam to power a steam-powered electricity generator to provide electricity, and charge a battery, during daylight hours, and then use the charged battery to supply electricity during the night hours, and (3) move water, cooled by the subsurface ground, by water pressure from a water spigot/bib, without pumping, into proximity with any air space inside any building to cool the air space.
