Multilayer Semen Extender Packaging with Desiccant Moisture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Semen extenders stored in sealed pouches are limited by specific temperature, humidity, and pressure conditions, leading to decreased semen motility and increased agglutination beyond these conditions.
Innovation Solution
A multilayer packaging film comprising polyethylene terephthalate, polyethylene, aluminum, and a desiccant, which forms a barrier to water vapor and oxygen, absorbs moisture, and maintains semen extender quality under varied storage conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If semen extenders are stored in sealed pouches under specific temperature, humidity and pressure conditions, then the quality of semen extender is preserved within a limited period, but the storage conditions must be very specific and limited, and the storage time is very limited
Solution Approach 1:
The packaging uses a multilayer composite structure comprising a first layer of polyethylene terephthalate, a second layer of polyethylene, a third layer of aluminium, and a fourth layer containing a desiccant. This composite material provides superior barrier properties against moisture and oxygen compared to single-layer pouches, enabling extended storage under varied conditions while maintaining semen extender quality
Solution Approach 2:
A desiccant is incorporated as an intermediary substance within the packaging system to actively control humidity. The desiccant absorbs excess moisture, creating a stable microenvironment that protects the semen extender from humidity-related degradation, thereby expanding the acceptable storage conditions range
2Adaptability or versatility
If semen extenders are stored beyond specific time and condition limits, then storage flexibility increases, but semen motility decreases and agglutination increases
Solution Approach 1:
The multilayer packaging with desiccant provides beforehand cushioning against environmental variations. By pre-establishing a protective barrier system that controls moisture and oxygen, the packaging cushions the semen extender from harmful effects during storage, maintaining semen motility even under extended or varied storage conditions
3Device complexity
If semen extenders are stored in sealed pouches, then the packaging is simple, but the storage period is very limited and conditions are restrictive
Solution Approach 1:
The packaging transitions from simple single-layer pouches to a multilayer composite structure with four distinct functional layers. This increased structural complexity provides enhanced barrier properties and environmental control, enabling storage periods of several months to years while maintaining semen extender quality under broader conditions
