Solution Overview

Problem

Conventional pool heaters are costly to purchase and maintain, inefficient, noisy, and contribute to greenhouse gas emissions, with high energy consumption and short lifespans, and existing cost-effective alternatives often fail to provide sufficient heating for normal-sized pools.

Innovation Solution

A temperature control apparatus using a composting chamber within a housing that generates heat through compost fermentation, with a conduit system for water flow, incorporating translucent portions for light heating and a mixing mechanism to enhance heat transfer, eliminating the need for external energy sources and reducing maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional pool heaters are used, then water heating function is provided, but high cost and high energy consumption occur

Engineering Contradiction:

Improvewater temperatureVSAvoidenergy consumption

Core Design Contradiction:

TemperatureVSUse of energy by moving object

Solution Approach 1:

The system uses composting organic material to generate heat autonomously without external energy sources. The composting chamber contains organic matter that decomposes naturally, producing thermal energy that transfers to the pool water through the housing walls, eliminating the need for gas, propane, or electricity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces mechanical heating systems (gas burners, electric elements) with a biological-chemical process (composting). The organic material undergoes natural decomposition, converting chemical energy stored in organic bonds into thermal energy, which then heats the water without mechanical intervention

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Temperature

If conventional pool heaters are used, then water heating function is provided, but high noise is generated

Engineering Contradiction:

Improvewater temperatureVSAvoidnoise

Core Design Contradiction:

TemperatureVSObject-generated harmful factors

Solution Approach 1:

The system replaces mechanical heating devices that generate noise (pumps, burners, fans) with a passive biological process. The composting chamber operates silently as organic material decomposes naturally, and heat transfers through conduction and convection without requiring noisy mechanical components

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Temperature

If conventional pool heaters are used, then water heating function is provided, but high purchase and maintenance cost occur

Engineering Contradiction:

Improvewater temperatureVSAvoidmanufacturing cost

Core Design Contradiction:

TemperatureVSEase of manufacture

Solution Approach 1:

The system uses inexpensive organic material (compost) as the heat source instead of expensive durable equipment. The composting chamber can be refilled with new organic material when depleted, replacing the need for expensive heater units that cost thousands of dollars to purchase and maintain

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

4Use of energy by moving object

If sunlight-based heaters are used, then cost reduction is achieved, but insufficient heating power is provided

Engineering Contradiction:

Improveenergy costVSAvoidheating power

Core Design Contradiction:

Use of energy by moving objectVSPower

Solution Approach 1:

The system changes the energy source from low-density solar radiation to high-density chemical energy stored in organic material. Composting generates significantly higher temperatures and more concentrated thermal energy compared to passive solar heating, providing sufficient power for normal-sized pools while maintaining low operational costs

Inventive Principle:

Principle #35Parameter changes

AI summary

An apparatus for controlling water temperature includes a housing defining a composting chamber for receiving compost and a conduit disposed within the housing for providing flow of water. The conduit at least partially receives heat generated by the compost and may include a first subconduit extending substantially about an axis of the housing, a second subconduit extending substantially about the axis of the housing and being spaced apart from the first subconduit and a plurality of elongated subconduits extending between the first subconduit and the second subconduit and providing fluid communication therebetween. The housing may have at least one translucent portion for permitting flow of light waves therethrough. The apparatus may have a mechanism for mixing the compost.
