Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for increasing sperm motility in animals, such as those used in artificial insemination, face challenges including the use of chemical agents that raise safety concerns and are costly, and existing light-based methods do not efficiently enhance motility beyond 50%.
Innovation Solution
Irradiating spermatozoa with light in the wavelength range of 390-420 nm, specifically at a fluence effective to increase motility by 75% or more, using a method and apparatus that includes a holding unit, a lighting unit capable of emitting light in this range, and a light controller to optimize irradiation parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If chemical agents are used to activate sperm motility, then sperm motility is improved, but safety concerns and cost increase
Solution Approach 1:
The patent replaces chemical activation methods with optical irradiation (light at specific wavelengths) to activate sperm motility. This substitution eliminates the need for chemical agents that raise safety concerns, while achieving the desired effect of increased sperm motility through non-invasive light exposure.
Solution Approach 2:
The patent changes the physical parameter of light wavelength (specifically using light in the range of approximately 390-420 nm) to achieve sperm activation. By optimizing the wavelength parameter, the method achieves effective motility enhancement without the harmful effects associated with chemical agents.
2Speed
If existing light-based methods are used to increase sperm motility, then some improvement is achieved, but the increase is limited to about 50%
Solution Approach 1:
The patent optimizes the light wavelength parameter to approximately 390-420 nm, which represents a specific refinement in the spectral range. This parameter optimization enables the method to achieve over 75% motility enhancement, significantly improving upon previous methods that were limited to about 50% enhancement.
