Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cultivating Oestridae larvae and maggots require them to be hosted in mammalian animals, making direct experimentation challenging and causing pathological effects on the host.
Innovation Solution
A two-tiered in vitro system with a semipermeable growth container and feeding source allows for the cultivation of Oestridae larvae and maggots, providing a controlled environment for experimentation without the need for a host animal, featuring adequate ventilation, temperature regulation, and moisture management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Oestridae larvae and maggots are cultivated in host mammals, then the larvae can survive and develop, but direct experimentation becomes difficult and pathological effects occur on the host
Solution Approach 1:
The patent extracts the larvae from the host animal system and places them in an artificial in vitro environment. The growth container with semipermeable walls provides the necessary containment and environmental control, allowing larvae to be cultivated without requiring a living host, thus enabling direct experimentation while maintaining larvae survival.
Solution Approach 2:
The semipermeable membrane acts as an intermediary between the larvae and the external environment. It allows selective exchange of substances while providing physical containment, mediating the interaction between the larvae and the controlled environment to maintain survival conditions without requiring a host animal.
2Stability of the object's composition
If Oestridae larvae and maggots are cultivated in host mammals, then the larvae can develop naturally, but pathological effects are inflicted on the host animal
Solution Approach 1:
The patent removes the larvae from the host animal system entirely, replacing the biological host environment with an artificial in vitro system. This extraction eliminates the harmful parasitic relationship while maintaining the conditions necessary for natural larval development through controlled environmental parameters.
Solution Approach 2:
The patent controls and adjusts environmental parameters such as temperature, humidity, and feeding fluid composition to replicate the natural host environment. By carefully managing these parameters in the artificial system, the larvae experience natural development conditions without the harmful effects associated with host infestation.
3Ease of operation
If a two-tiered in vitro system is used to cultivate Oestridae larvae, then direct experimentation becomes possible, but the device complexity increases
Solution Approach 1:
The patent divides the cultivation system into two distinct tiers: an upper growth container for housing the larvae and a lower collection container for waste and excess feeding fluid. This segmentation allows for better control of the cultivation environment and easier access to larvae for experimentation, while the modular design keeps the overall complexity manageable.
Solution Approach 2:
The patent introduces a vertical dimension with the two-tiered structure, stacking the growth and collection functions in different spatial levels. This vertical arrangement allows for efficient use of space and facilitates easy access to the larvae in the upper tier for experimentation without complicating the horizontal layout.
4Adaptability or versatility
If semipermeable material is used for the growth container walls, then environmental control is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs semipermeable or porous materials for the growth container walls, which allow selective passage of substances while maintaining structural integrity. These materials provide the necessary environmental control through their inherent permeability properties, and standard manufacturing techniques for porous materials can meet the required precision without excessive complexity.

Function Achieved in This Case
Enables direct experimentation on Oestridae larvae and maggots while avoiding the drawbacks of host-based cultivation, such as pathological effects and logistical challenges, by creating a suitable in vitro environment for their growth and maintenance.
Implementation Method 1
a growth container comprising at least one wall and a floor, both the at least one wall and the floor of the growth container being made of semipermeable material
Implementation Method 2
the bottom of the upper tier is porous to separate the waste fluids coming out from the growing Oestridae larvae and maggots by allowing the dripping of the waste into the bottom tier container
Implementation Method 3
allowing the dripping of the waste into the bottom tier container
