Solution Overview

Problem

Container gardening faces challenges in maintenance requirements such as watering and fertilizing, particularly in providing efficient nutrient delivery to plants.

Innovation Solution

A modular, expandable garden tower planter with an internal vertical composting tube system that uses worms to convert compost into nutrient-rich 'worm tea' fertilizer, allowing for efficient nutrient recycling and plant growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If plants are grown in containers, then portability and space efficiency are improved, but maintenance requirements for watering and fertilizing increase

Engineering Contradiction:
Improvespace efficiencyVSAvoidmaintenance requirements
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent combines the composting function and plant growing function into a single integrated container system. The compost material is placed at the bottom of the same container that holds the plants, eliminating the need for separate fertilization processes and reducing maintenance requirements while maintaining space efficiency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system enables self-fertilization through compost decomposition. As compost material decomposes in the container, it naturally releases nutrients that are absorbed by the plants growing in the same container, creating a self-sustaining system that reduces the need for external fertilization intervention.

Inventive Principle:
Principle #25Self-service

2Area of stationary object

If a single large container is used for plants, then space utilization is improved, but packaging and storage efficiency worsen

Engineering Contradiction:
Improvespace utilizationVSAvoidpackaging volume
Core Design Contradiction:
Area of stationary objectVSVolume of stationary object

Solution Approach 1:

The container system is divided into modular components including a removable insert with compartments for compost material and plant growing media. These segmented parts can be disassembled and nested within each other for compact storage and efficient packaging, while assembling to form a larger functional unit for plant cultivation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The removable insert and various container components are designed to nest within each other when disassembled. The smaller compartments fit within larger structures, creating a compact nested configuration that reduces packaging volume and improves storage efficiency while maintaining the ability to form a large functional container when assembled.

Inventive Principle:
Principle #7Nested doll (Nesting)

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 system reduces maintenance needs by automating nutrient delivery, promoting healthy plant growth through the use of worm tea, while also being modular and compact for efficient packaging and storage.

Implementation Method 1

The inner tube is sized, shaped and positioned to be filled with compost material. A plurality of worms may be added to the inner tube compost material. In this way a portion of the compost material may be converted into organic 'worm tea' fertilizer

Methodology Applied
Scientific EffectComposting: Composting
