Solution Overview

Problem

Existing composting containers do not effectively introduce sufficient additional air to enhance aerobic decomposition of organic materials, and they lack efficient mechanisms to facilitate airflow through the base structure, which can impede the decomposition process and leachate collection.

Innovation Solution

A composter design featuring a base structure with spaced pillars that support the floor and extend upwardly from the leachate tank, creating an air flow path from outside the composter to the aerator, allowing air to flow through the floor and into the composting chamber above the leachate liquid level, thereby improving aerobic decomposition and facilitating leachate collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a solid base structure is used to support the floor, then structural strength is improved, but air flow through the base is blocked

Engineering Contradiction:
Improvebase structure strengthVSAvoidair flow quantity
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The base structure incorporates pillars with void spaces between them, creating a porous configuration that allows air to pass through while maintaining structural support. The pillars are spaced to provide sufficient structural strength while their open arrangement between them creates pathways for air flow from the exterior into the leachate tank and up to the floor openings.

Inventive Principle:
Principle #31Porous materials

2Stability of the object's composition

If the floor is placed directly on the base, then structural stability is improved, but air flow path is blocked

Engineering Contradiction:
Improvefloor stabilityVSAvoidair flow quantity
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The base structure is segmented into multiple pillars rather than a continuous solid base. This segmentation creates gaps and pathways between the pillars that allow air to flow through the base structure while each pillar individually provides sufficient support to maintain floor stability.

Inventive Principle:
Principle #1Segmentation

3Quantity of substance

If a centrally positioned aerator is used, then air distribution is improved, but additional air introduction through the base is limited

Engineering Contradiction:
Improveair distributionVSAvoidair introduction pathways
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The base structure with its porous pillar arrangement serves multiple functions: it provides structural support for the floor, collects leachate in the tank beneath, and simultaneously acts as an air introduction pathway. This multi-functionality complements the central aerator by providing an additional air introduction route, enhancing overall air distribution and aerobic decomposition capability.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The enhanced airflow through the base structure significantly improves the aerobic decomposition of organic materials, leading to quicker composting and better quality compost, while the leachate collection system ensures efficient drainage and separate handling of leachate.

Implementation Method 1

the air flow path provides air from outside the composter to openings located in the floor above the leachate tank, the pillars facilitating air flow through the floor by allowing air to flow out into the leachate tank above a leachate liquid level and to the openings in the floor to facilitate aerobic decomposition of the composting material

Methodology Applied
Scientific EffectAir flow: Convection

Implementation Method 2

the aerator within the container having at least one opening for allowing air to pass from the aerator into the container

Methodology Applied
Scientific EffectAerobic decomposition: Aerobic Digestion

Implementation Method 3

a base structure defining a floor on which the composting material sits above a leachate tank located under the floor

Methodology Applied
Scientific EffectGravity drainage: Gravitation
