Solution Overview

Problem

Existing animal feed additives containing oligoelements like manganese, zinc, and selenium pose toxicity risks to handlers and the environment due to inhalation and exposure during production, and lack homogeneous distribution within the feed, leading to uneven nutrient delivery to animals.

Innovation Solution

A process involving the mixing of mineral raw material granules with sepiolite granules of specific size ranges, followed by coating with different agents to enhance oligoelement adhesion and distribution, resulting in a safer, more homogeneous animal feed additive with reduced emissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If oligoelements are added to animal feed in conventional forms, then nutritional requirements are met, but toxic emissions during handling and production increase

Engineering Contradiction:
Improveoligoelement contentVSAvoidtoxic dust emissions
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent uses a carrier material (such as bentonite, zeolite, or other inert matrices) as an intermediary substance to bind the oligoelements. This carrier acts as a mediator that holds the toxic oligoelements in a stable, low-dust form, preventing their release as inhalable particles during handling while still delivering the required nutritional quantity to animals.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs coating materials that form protective layers or films around the oligoelement-containing carrier particles. These coatings create a physical barrier that reduces dust generation and toxic emissions during production and handling, while maintaining the oligoelement delivery function.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of manufacture

If oligoelements are distributed in feed without specialized processing, then production is simple, but homogeneous distribution throughout the feed is not achieved

Engineering Contradiction:
Improveadditive preparation simplicityVSAvoidoligoelement distribution uniformity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent segments the oligoelement delivery system into discrete, pre-formulated additive particles with controlled size and composition. By dividing the oligoelements into many small, uniform carrier-bound particles, the system achieves homogeneous distribution throughout the feed while maintaining relatively simple manufacturing processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent optimizes physical parameters such as particle size distribution, surface area-to-volume ratio, and carrier particle morphology to enhance dispersion uniformity. By controlling these parameters during additive formulation, homogeneous oligoelement distribution is achieved without requiring complex processing equipment or procedures.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If conventional feed additives are used, then oligoelement supplementation is provided, but emissions during storage and transport increase

Engineering Contradiction:
Improvenutrient delivery assuranceVSAvoidenvironmental emissions
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the inherent toxicity and dust-generating properties of oligoelements into a beneficial low-emission formulation by binding them to carriers and applying coatings. This transformation maintains the nutritional reliability while converting the harmful dust-emission characteristic into a stable, controlled-release system that reduces environmental emissions during storage and transport.

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

Solution Approach 2:

The patent creates composite additive structures combining carrier materials, oligoelements, and coating substances into integrated particles. This composite approach ensures reliable nutrient delivery through the carrier-oligoelement complex while the coating layer provides protection against emissions, achieving both reliability and reduced environmental impact.

Inventive Principle:
Principle #40Composite materials
