Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current animal feed additives often have trace minerals in forms that are not highly bioavailable, leading to inefficiencies in nutritional delivery and potential environmental harm due to high metal concentrations.
Innovation Solution
The use of ethylene diamine (EDA) metal complexes, specifically with copper, zinc, iron, and manganese, which are designed to be highly absorbable, soluble, and stable at physiological conditions, ensuring effective delivery and utilization by animals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If inorganic metal sources are used in animal feed, then the concentration of trace minerals can be increased to meet nutritional needs, but the bioavailability and absorption efficiency decrease
Solution Approach 1:
The patent uses organic ligands (amino acids, peptides, proteins) as intermediaries to bridge the gap between inorganic metal sources and animal absorption systems. These ligands form stable complexes with metal ions, creating a carrier system that protects the metals from precipitation in the acidic gut environment while facilitating their transport across intestinal membranes for efficient absorption.
Solution Approach 2:
The patent changes the chemical form of metal supplements from simple inorganic salts to organized complex structures with specific ligands. This parameter change in molecular organization transforms the physical and chemical properties of the metals, enhancing their solubility, stability, and bioavailability while allowing lower concentrations to meet nutritional requirements.
2Quantity of substance
If higher concentrations of metal supplements are added to feed, then nutritional needs can be met, but harmful effects on animals and environment increase
Solution Approach 1:
By changing the chemical form of metal supplements from inorganic to organic complexes, the patent alters the toxicity profile. The organic ligands modulate the bioavailability of metals, allowing precise control over absorption rates and tissue distribution, thereby meeting nutritional needs at lower concentrations while reducing toxic effects.
Solution Approach 2:
The patent employs biodegradable organic ligands (amino acids, peptides, proteins) that are naturally metabolized by animals. These ligands serve as temporary carriers that deliver metals to target tissues and then break down into harmless components, eliminating persistent environmental contamination associated with inorganic metal supplements.
3Ease of manufacture
If inorganic metal sources are used, then manufacturing is simple and cost-effective, but absorption and utilization by animals are poor
Solution Approach 1:
The patent applies preliminary chemical action by pre-forming stable metal complexes with organic ligands before feed formulation. This pre-organization of metals into bioavailable forms during manufacturing ensures that the supplements are ready for efficient absorption upon ingestion, eliminating the need for complex in-situ formation processes while maximizing nutritional utilization.

Function Achieved in This Case
These EDA metal complexes enhance bioavailability, allowing for lower concentrations of trace minerals in animal feed while maintaining nutritional efficacy and reducing environmental impact, as demonstrated by improved absorption and utilization in animal trials compared to inorganic sources.
Implementation Method 1
The enhanced bioavailability is attributed to the association of the metal with an organic molecule, generally known as a ligand. This association or bonding results in the increased availability of the metal for utilization by animals
Implementation Method 2
These EDA metal complexes enhance bioavailability, allowing for lower concentrations of trace minerals in animal feed while maintaining nutritional efficacy
