Frangible-Bottom Capsule Delivery Preserves Microorganism Viability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many species of microorganisms used in agricultural applications are fragile and cannot survive long-term outside their natural environment, leading to reduced efficacy when premixed with agricultural inputs.
Innovation Solution
A device comprising a capsule with a frangible bottom and a plunger mechanism that allows for the controlled release of biological material into a liquid medium, maintaining the viability of the microorganisms until application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If biological material is premixed with agricultural inputs, then application efficiency is improved, but microorganism viability deteriorates due to fragility outside natural environment
Solution Approach 1:
The device divides the agricultural input system into separate components: a container for agricultural inputs and a capsule for biological material. This segmentation allows each component to be optimized independently - the container for delivery efficiency and the capsule for microorganism protection - while still achieving combined application at the target site.
Solution Approach 2:
The capsule acts as an intermediary carrier that protects biological material during storage and transport, then releases it at the application site. This intermediary structure shields fragile microorganisms from harsh conditions while enabling eventual mixing with agricultural inputs only when needed.
2Duration of action of stationary object
If biological material is stored long-term outside natural environment, then storage duration is extended, but microorganism viability deteriorates
Solution Approach 1:
The capsule creates a protected internal environment that mimics natural conditions for microorganisms, isolating them from harmful external factors during storage. This inert environment preservation allows long-term storage while maintaining microorganism viability until application time.
Solution Approach 2:
The capsule is pre-prepared and stored with biological material in a protected state before application. This preliminary preparation allows the system to be ready in advance while the microorganisms remain viable, enabling on-demand application without compromising their survival.
3Ease of operation
If capsule structure is designed with plunger mechanism, then delivery control is improved, but device complexity increases
Solution Approach 1:
The plunger mechanism is designed to be activated by simple user action (pushing or twisting), and once activated, the system self-regulates the release process. The frangible bottom automatically breaks when the plunger reaches it, eliminating the need for complex control systems while maintaining ease of operation.
Solution Approach 2:
The capsule is designed as a disposable single-use component with a simple frangible bottom rather than a complex reusable mechanism. This approach reduces overall device complexity by using an inexpensive, replaceable element that breaks irreversibly upon activation, simplifying the overall system design.
