Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current insect sampling methods in agriculture, such as sweep net sampling and plant vacuuming, are inaccurate, destructive to plants, and fail to represent natural enemies effectively, leading to underestimation of pest populations and damage to crops.
Innovation Solution
A carbon dioxide-based insect sampling device that anesthetizes insects using a calibrated CO2 gas discharge system, allowing for targeted and non-destructive collection of specific insect species or communities, overcoming the limitations of existing methods by providing a more accurate and efficient sampling technique.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If sweep net sampling or plant vacuuming is used to collect insects, then insect samples can be obtained, but plants are damaged (leaves tear or detach, fruit or flowers separated from plant)
Solution Approach 1:
The patent replaces mechanical collection methods (sweep nets, vacuuming) with a chemical/biological method using CO2 gas to anesthetize insects. This substitution eliminates the need for physical contact with plants, thereby preventing plant damage while still enabling effective insect collection.
Solution Approach 2:
The patent introduces CO2 gas as an intermediary substance between the collector and the insects. The gas acts as a mediator that anesthetizes insects without requiring direct mechanical interaction with the plant, thus protecting the plant from damage while achieving the collection objective.
2Quantity of substance
If plant vacuuming is used to collect insects, then insects can be gathered, but sampling accuracy decreases due to sound and vibration disturbing insect populations
Solution Approach 1:
The patent replaces the mechanical vacuum system that generates disruptive sound and vibration with a chemical anesthesia method using CO2 gas. This substitution eliminates the disruptive physical effects while maintaining effective insect collection, thereby preserving sampling accuracy.
3Quantity of substance
If plant vacuuming is used to collect insects, then insects can be gathered, but small insects are disproportionately minimized or destroyed by suction
Solution Approach 1:
The patent replaces the mechanical suction system with a chemical anesthesia method using CO2 gas. This substitution eliminates the size-biased destruction caused by vacuum suction, allowing small insects to be collected intact and preserving the true size distribution of the insect population.
4Quantity of substance
If sweep net sampling or plant vacuuming is used, then insects can be collected, but the methods over-represent prominent pests while under-representing natural enemies
Solution Approach 1:
The patent replaces mechanical collection methods that create behavioral biases with a chemical anesthesia method using CO2 gas. This substitution eliminates the differential response of different insect types to mechanical stimuli, thereby providing a more accurate representation of the true insect community composition including both pests and natural enemies.
5Quantity of substance
If portable aspirator method is used to collect insects, then insects can be gathered, but the method is time-consuming
Solution Approach 1:
The patent extracts the time-consuming aspect of manual aspirator operation by using a CO2 gas system that can anesthetize insects more rapidly and efficiently. The gas delivery system allows for faster collection compared to the manual, step-by-step aspirator method.
6Quantity of substance
If tapping flower clusters method is used to collect insects, then insects can be gathered, but the method is biased towards collecting immature insects
Solution Approach 1:
The patent replaces the mechanical tapping method with a chemical anesthesia method using CO2 gas. This substitution eliminates the developmental stage bias inherent in tapping, which preferentially collects immature insects that are more easily dislodged, thereby providing a more accurate representation of the full insect population across all developmental stages.
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 enables precise and efficient collection of targeted insects without harming plants, reducing operator time, and improving sampling accuracy by anesthetizing insects without causing plant damage or disturbing populations, thus providing a more reliable estimation of pest population dynamics.
Implementation Method 1
An alternative insect sampling method is the use of carbon dioxide (CO2) gas to anesthetize insects. CO2 gas is used as an insect anesthetic in many laboratories
