Sinking Insecticide Granule with Disintegration Agent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insecticides struggle to target aquatic pests effectively due to differences in density between the insecticide and the pest, leading to inadequate contact and reduced efficacy, as they either float on the surface or sink too quickly.
Innovation Solution
A formulation comprising a Bacillus thuringiensis (BT) strain, a floating agent, and a disintegration agent bound on a substrate with a density greater than water, allowing the granule to sink and release BT throughout the water column for immediate efficacy against mosquito larvae.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the insecticide product is made light (density less than 1), then it floats on the water surface, but it drifts with wind and does not reach targeted locations effectively
Solution Approach 1:
The patent changes the density parameter of the insecticide formulation to be greater than 1, transforming it from a floating product to a sinking product. This parameter change allows the formulation to sink through the water column and reach pests at various depths, resolving the contradiction between floating behavior and targeting accuracy.
2Weight of moving object
If the insecticide product is made heavy (density greater than 1), then it sinks to the bottom, but it does not release the insecticide fast enough to be effective
Solution Approach 1:
The patent incorporates a disintegration agent in the formulation that pre-prepares the carrier material to break down rapidly upon contact with water. This preliminary action ensures that when the dense formulation sinks, it immediately disintegrates and releases the insecticide, resolving the contradiction between sinking behavior and release rate.
Solution Approach 2:
The patent creates a composite formulation combining the insecticide active ingredient with a carrier material and a disintegration agent. This composite structure allows the formulation to maintain density greater than 1 for sinking while the disintegration agent ensures rapid breakdown and insecticide release, resolving the contradiction between sinking and release rate.
3Ease of operation
If the insecticide is applied as a light product, then it is easy to apply, but it hangs up in vegetation and does not reach the water column where pests reside
Solution Approach 1:
The patent changes the density parameter from less than 1 to greater than 1, fundamentally altering the product's behavior in the environment. This change ensures the formulation sinks through the water column rather than floating or hanging in vegetation, improving delivery effectiveness to where pests actually reside.
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 formulation ensures that BT is released throughout the water column, providing immediate and effective control of mosquito larvae, with the option for a secondary insecticide like methoprene for prolonged action.
Implementation Method 1
the substrate is denser than water causing the granule to sink to the bottom of the water column
Implementation Method 2
a disintegration agent bound on a substrate
