Selectively Permeable Wall for Sperm Sex Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for influencing the sex of offspring, such as the Chinese conception calendar and STORCH parameters, are time-consuming and require significant interpretation, while artificial insemination methods for sex selection are technically and financially demanding.
Innovation Solution
A device featuring a selectively permeable separating wall with pores or mesh sizes adapted to differentiate between X- and Y-spermatozoa, allowing increased permeability for one type while retaining the other, which can be inserted into the vaginal passage or used with a penis during coitus to enrich spermatozoa for fertilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional methods (Chinese conception calendar, STORCH parameters) are used to influence offspring sex, then sex selection is attempted, but the process becomes time-consuming and requires significant interpretation
Solution Approach 1:
The invention extracts and isolates the interpretation and time-consuming elements of conventional methods by replacing them with a physical device that directly separates spermatozoa based on their natural swimming behaviors, eliminating the need for calendar calculations and parameter interpretation
Solution Approach 2:
The invention introduces a physical intermediary (the device with selectively permeable separating wall) that mediates the sex selection process by passively separating spermatozoa based on their inherent motility differences, rather than requiring active human interpretation of complex parameters
2Manufacturing precision
If artificial insemination methods are used for sex selection, then sperm separation is achieved, but high technical and financial demands are required
Solution Approach 1:
The device utilizes the self-service principle by exploiting the natural, inherent differences in swimming behaviors between X and Y spermatozoa, allowing them to self-separate without requiring complex external control systems, advanced instrumentation, or highly trained personnel
Solution Approach 2:
The invention employs a simple, disposable device structure with a selectively permeable separating wall that can be manufactured at low cost and used single-use, eliminating the need for expensive, complex, and reusable laboratory equipment required in traditional artificial insemination methods
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 device effectively increases the probability of achieving a specific sex by separating and enriching spermatozoa, providing a higher percentage of either Y- or X-spermatozoa for fertilization, thus enhancing the chances of male or female birth without high technical or financial burdens.
Implementation Method 1
the separating wall shows increased permeability for Y-chromosome-bearing spermatozoa... the selectively permeable separating wall serves the enrichment of X-chromosome-bearing spermatozoa or Y-chromosome-bearing spermatozoa downstream of the separating wall
