Semi-Permeable Ceratitis Attractant Container for Controlled Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for attracting and trapping Ceratitis capitata insects face issues such as uncontrolled release of attractants, the need for multiple components and steps in production, and potential skin irritation from volatile substances, particularly due to the use of aminoalkanes like cadaverine and putrescine.
Innovation Solution
A device comprising a container with impermeable walls and a semi-permeable lid, containing an aqueous attractant composition that includes ammonium acetate and trimethylamine hydrochloride, allowing controlled vapor release without aminoalkanes, and can be directly used in trapping devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If feromones are used to attract diptera, then the attraction effectiveness is improved, but the cost of maintaining the device increases due to frequent replacement of feromone cartridges
Solution Approach 1:
The patent changes the physical state of feromones from liquid (in cartridges) to solid (impregnated on substrate), and alters the release mechanism from active diffusion to passive evaporation through heat treatment, thereby reducing feromone consumption and eliminating the need for frequent cartridge replacements
Solution Approach 2:
The patent replaces expensive, frequently replaced feromone cartridges with a more durable substrate that can be reused for extended periods, reducing operational costs and waste
2Productivity
If UV lights are used to attract diptera, then the attraction effectiveness is improved, but the energy consumption increases
Solution Approach 1:
The patent employs periodic flashing of UV lights instead of continuous illumination, reducing energy consumption while maintaining attraction effectiveness through intermittent light pulses that mimic natural patterns
Solution Approach 2:
The patent adjusts the intensity and duration of UV light emission parameters to optimize attraction effectiveness while minimizing energy consumption, using controlled pulsing rather than continuous high-power operation
3Productivity
If the trapping device is placed in open areas, then the attraction effectiveness is improved, but the risk of animal accidents increases
Solution Approach 1:
The patent introduces a mesh screen as an intermediary element between the trapping area and the exterior, allowing diptera to access the trap while preventing contact with hazardous components and reducing the risk of animal accidents in open placements
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 device ensures a prolonged and controlled release of the attractant composition, which enhances the effectiveness of the attractant composition, reducing the need for separate storage in the device, and minimizes the risk of skin irritation and the attractant composition, while effectively attracting and trapping a high number of insects.
Implementation Method 1
a source of ultraviolet light for attracting diptera of the ceratitis type
Implementation Method 2
