Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current assisted reproductive technology (ART) methods for animal breeding, such as IVF and AI, face challenges due to the fragility of gametes, leading to reduced viability, motility, and fertility, especially during processing and storage, which increases costs and inefficiencies, particularly for smaller breeders seeking gender selection.
Innovation Solution
The use of magnetic particles with a magnetic substrate and a chargeable silicon-containing compound to manipulate and process sperm, improving motility, viability, and fertility by selectively removing damaged cells and reducing stress during handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ART processing methods are used to handle and process gametes, then the procedures can be performed with standard techniques, but the gametes suffer from reduced viability, motility, and fertility due to stress and damage during processing and storage
Solution Approach 1:
The patent introduces magnetic particles as an intermediary medium to manipulate gametes. These particles bind to gametes and allow separation and processing through magnetic field application, replacing direct mechanical handling that causes stress and damage to the fragile gamete structures.
Solution Approach 2:
The patent replaces mechanical handling and manipulation of gametes with a magnetic field-based system. Instead of physical contact and mechanical separation methods that damage gametes, the invention uses magnetic fields to manipulate particles bound to gametes, enabling non-contact processing that preserves gamete integrity.
2Manufacturing precision
If sex sorting processes are applied to separate X and Y bearing sperm, then gender enriched sperm populations are achieved, but the sperm cells undergo severe stress and damage resulting in reduced viability, motility, and fertility
Solution Approach 1:
The patent uses magnetic particles as intermediaries that bind to sperm cells during sex sorting. These particles enable magnetic field-based separation of X and Y bearing sperm based on their different magnetic susceptibilities, achieving gender selection without the severe mechanical stress and damage caused by conventional sorting methods.
Solution Approach 2:
The patent exploits differences in magnetic susceptibility as a physical parameter to differentiate and separate X and Y bearing sperm. By applying magnetic fields and utilizing the distinct magnetic properties of sperm bearing different sex chromosomes, the invention achieves precise gender selection while maintaining sperm viability through non-destructive separation.
3Reliability
If high numbers of sperm are used per AI dose to ensure successful fertilization, then fertilization success is achieved, but the cost and inefficiency of ART procedures increase significantly
Solution Approach 1:
The patent extracts and removes damaged, dead, or compromised sperm from the population using magnetic particle binding and magnetic field separation. This purification process concentrates viable, high-quality sperm, enabling the use of lower numbers per AI dose while maintaining or improving fertilization success rates, thereby reducing costs and increasing efficiency.
Solution Approach 2:
The patent changes the physical parameter of magnetic susceptibility to differentiate and separate viable sperm from damaged sperm. By exploiting differences in magnetic properties between healthy and compromised sperm cells, the invention enables precise selection and concentration of high-quality sperm, improving fertilization efficiency and reducing the number needed per dose.
4Productivity
If multiple harsh processing steps are applied including staining, physical sorting, and freezing, then sperm separation and preservation are achieved, but the cumulative stress severely diminishes overall motility, viability, and fertility
Solution Approach 1:
The patent replaces multiple harsh mechanical processing steps with a unified magnetic field-based system. Instead of sequential staining, physical sorting, and freezing operations that cumulatively damage sperm, the invention uses magnetic particles and magnetic fields to achieve separation and preservation in a gentler, more integrated process that maintains sperm quality.
Solution Approach 2:
The patent creates a multi-functional magnetic particle system that performs multiple operations simultaneously: binding to sperm, enabling separation based on magnetic susceptibility differences, and facilitating preservation. This universal approach replaces multiple specialized harsh processing steps with a single integrated gentle process that maintains overall sperm quality.
