Solution Overview

Problem

Agricultural crops, such as oil seed rape, face significant losses due to pests like the cabbage stem flea beetle, and there is a need for effective methods to reduce organic waste and improve crop growth and protection.

Innovation Solution

A coated seed comprising a bioadhesive and one or more bioactive agents, where the bioadhesive includes protein-containing biomaterials, an inorganic filler, and a defoamer, and the bioactive agents can be biorepellents, pesticides, fertilizers, or bactericides, is used to enhance seed protection and growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biorepellents or fertilizers are applied to soil by sprinkling or spreading, then plant growth is improved and pest damage is reduced, but large volumes of material are needed and the distribution is random and uneven

Engineering Contradiction:

Improveprotection effectivenessVSAvoidvolume of bioactive agent

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The bioactive agent is applied to the seed before planting, allowing the protective and fertilizing effects to be established in advance. The coating is applied to seeds prior to sowing, ensuring that protection is present from the earliest stages of plant development rather than being applied to soil after planting.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The bioactive agent is concentrated locally on the seed surface through coating, creating a high-density zone of protection exactly where it is needed most. This localized application ensures that each seed receives a sufficient dose without requiring large volumes to be distributed across the entire soil area.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If biorepellents are applied to soil, then some pest protection is achieved, but pest larvae already inside the crop remain unprotected and continue to cause damage

Engineering Contradiction:

Improvepest damageVSAvoidcompleteness of protection

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The seed coating provides protection before the plant is even established, creating a protective barrier that prevents pest larvae from infesting the seed and early seedling. This preliminary protection covers the critical vulnerable period from sowing through germination, when the plant is most susceptible to pest attack.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The coating concentrates the bioactive agent directly on the seed surface and within the seed structure, creating a localized protective zone that specifically targets pests attempting to attack the seed and emerging seedling. This ensures complete coverage of the most vulnerable parts of the plant.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If synthetic polymer adhesives are used in seed coating, then coating adherence is improved, but nonbiodegradable waste accumulates in soil and soil quality deteriorates

Engineering Contradiction:

Improvecoating adherenceVSAvoidsoil pollution

Core Design Contradiction:

Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The adhesive material has been changed from synthetic polymer to natural biopolymer, fundamentally altering its degradation properties. This parameter change transforms the adhesive from persistent and harmful to transient and beneficial, allowing it to perform its binding function during the critical early growth period then decompose naturally to enrich the soil.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The adhesive, instead of being a source of pollution as with synthetic polymers, is now derived from natural materials that will decompose and contribute organic matter and nutrients to the soil. The decomposition process converts what would have been waste into a beneficial soil amendment.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
