Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing methods for protecting plant root balls during transportation and handling are inadequate, leading to root damage, mess, and safety concerns due to the weight and messiness of soil, as well as limited protection when using containers or burlap and wire.

Innovation Solution

Applying a semi-permeable agricultural polymer coating around the root ball, which can be done by dipping or spraying a mixture of agricultural polymer and water, creating a biodegradable protective layer that allows for easier handling and transportation without containers, while maintaining root health.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a plant is transported in a container, then the root ball is protected, but the container becomes heavy and difficult to move

Engineering Contradiction:

Improveroot ball protectionVSAvoidcontainer weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The invention extracts the protective function from the heavy container and transfers it to a lightweight biodegradable coating applied directly to the root ball. This eliminates the need for bulky containers while maintaining root ball protection during transport and handling.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the physical state and properties of the protective material from solid container walls to a liquid/solid biodegradable coating that forms a flexible protective layer around the root ball, significantly reducing weight while maintaining protective capabilities.

Inventive Principle:

Principle #35Parameter changes

2Stability of the object's composition

If soil is placed in a container, then the root ball is supported, but the soil becomes messy and spills during handling

Engineering Contradiction:

Improveroot ball stabilityVSAvoidsoil spillage

Core Design Contradiction:

Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The biodegradable coating forms a flexible shell around the root ball that contains the soil and roots, preventing spillage during handling and transport while allowing the root ball to maintain its stable composition without requiring a rigid container.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The invention uses composite materials combining biodegradable polymers with natural fibers or other additives to create a coating that provides both structural support to contain soil and flexibility to prevent spillage during handling.

Inventive Principle:

Principle #40Composite materials

3Shape

If burlap and wire are used to wrap the root ball, then the root ball is maintained, but the protection is minimal and roots are damaged during removal

Engineering Contradiction:

Improveroot ball shapeVSAvoidroot protection

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

The biodegradable coating forms a flexible protective shell that maintains the root ball shape during transport and provides continuous protection to the roots, eliminating the need for rigid wire structures that can cause damage during removal.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The coating is applied to the root ball before transport and remains in place throughout handling, providing preliminary and continuous protection to the roots rather than requiring removal and reapplication of protective materials at the destination.

Inventive Principle:

Principle #10Preliminary action

4Reliability

If a thick coating of agricultural polymer is applied, then root protection is improved, but the application time and material usage increase

Engineering Contradiction:

Improveroot protectionVSAvoidcoating application time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The invention optimizes the coating parameters including thickness, polymer concentration, and application method to achieve adequate root protection with minimal material usage and application time, balancing protective effectiveness with processing efficiency.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The coating is applied to provide sufficient protection with a thickness that is adequate but not excessive, optimizing the balance between protective capability and material/time consumption during application.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A root ball including soil disposed in and around root system and a layer of agricultural polymer around the soil and root system. The agricultural polymer creates a root ball having a semi-permeable, solid outer layer, which provides protection for the root system and eliminates the need for a container.
