Biodegradable Plant Shield With Nutrient Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant shields do not effectively protect seedlings from pests like cutworms that attack at the soil surface and lack the ability to provide nutrients for root growth, as they are typically simple annular barriers made from non-degradable materials.
Innovation Solution
A biodegradable plant shield with a walled structure that can be partially buried in soil, featuring an above-ground barrier and a below-ground portion with integrated plant nutrients, formed through injection molding and comprising components that assemble around the plant to prevent pest access and facilitate root growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If simple annular barriers made from non-degradable materials are used, then pest protection is provided, but the barriers cannot add nutrients to the soil and require removal and disposal
Solution Approach 1:
The patent changes the material parameter from non-degradable to biodegradable, allowing the shield to naturally decompose in the soil and release nutrients while maintaining protective function during the growth period
Solution Approach 2:
The patent converts the previously harmful waste disposal requirement into a beneficial nutrient source by using biodegradable materials that decompose and enrich the soil
2Duration of action of stationary object
If degradable materials like compressed peat moss are used, then the shield can be buried in the ground, but the material's frailness limits the ability to incorporate additional features
Solution Approach 1:
The patent uses composite materials that combine the biodegradable base material with added structural components, enabling both burial durability and feature integration
Solution Approach 2:
The shield is divided into functional segments (above-ground barrier portion and below-ground nutrient portion) that can be independently optimized while maintaining overall structural integrity
3Ease of manufacture
If shields are made as simple annular walls, then manufacturing is simple, but they lack features for ground engagement control and nutrient provision
Solution Approach 1:
The patent designs a multi-functional shield that simultaneously provides pest barrier protection, controlled ground engagement through divider elements, and nutrient provision through biodegradable material decomposition
Solution Approach 2:
The patent adds vertical dimensionality with divider elements that extend along the shield's length, creating above-ground and below-ground functional zones without complicating the basic annular structure
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 shield effectively protects seedlings from ground-traveling pests while providing nutrients to the soil as it biodegrades, enhancing root development and reducing the need for separate pest control measures.
Implementation Method 1
The shield can comprise a Biodegradable Plastic that includes plant nutrients within the Biodegradable Plastic

AI summary
Shielding for the protection of plants and seedlings from ground pests is provided. Shields can be comprised of materials including biodegradable materials that have the advantage of being formed into plant protection shields with various features, such as by an injection molding process, but that can be buried within the soil along with a plant's roots. Plant shields are provided for being partially buried in soil to surround a plant and for providing above-ground protection from ground travelling pests. Such shields can comprise a walled structure surrounding and creating an open-ended enclosure with the shield comprising an above the ground portion and a below the ground portion. The shield may comprises a Biodegradable Plastic that includes plant nutrients within the Biodegradable Plastic. The above the ground portion and the below the ground portion can be divided from one another by a divider that extends along an external surface of the walled structure in a similar direction as the walled structure surrounds the enclosure, the divider element comprising a ground engagement surface for limiting insertion of the shield into the soil.
