Light-Guiding Insect Trap Structure for Lower-Canopy Pest Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insect traps face issues where light from the attraction light source does not reach the lower areas, reducing the probability of pest attraction and extermination, and tall crops suffer from cold air retention leading to disease and reduced production.
Innovation Solution
The insect trap incorporates a long transparent cylindrical part made of synthetic resin with openings at the top and bottom, transmitting light to lower areas, and includes a fan to generate airflow for pest attraction and extermination, along with an adhesive and protective net for enhanced trapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a bait well is used to hold attractant, then the attractant can be contained and applied effectively, but the trapped insect remains visible and accessible to predators and environmental factors
Solution Approach 1:
The invention employs a nested structure where an inner capture well containing the trapped insect is positioned inside an outer bait well. The inner well is suspended within the outer well such that the trapped insect is concealed from external view while remaining contained. This nesting arrangement protects the trapped insect from predators and environmental factors without requiring additional external protective structures, thereby resolving the contradiction between protection and complexity.
2Device complexity
If the trap structure is simplified without a bait well, then the device complexity is reduced, but the attractant cannot be effectively contained or applied to lure insects
Solution Approach 1:
The invention merges the functions of attractant containment and insect capture into a single integrated dual-well structure. The outer bait well holds the attractant while the inner capture well collects trapped insects, with both wells forming one cohesive trap assembly. This merging eliminates the need for separate bait containers and capture chambers, maintaining effective attractant application while simplifying the overall device structure compared to traditional multi-component traps.
3Device complexity
If the attractant is applied in a separate container, then the application mechanism is simplified, but the attractant cannot be effectively dispersed or presented to flying insects
Solution Approach 1:
The invention applies local quality by positioning the attractant in the outer bait well at a specific location that is optimally exposed to flying insects while maintaining a clear spatial separation from the inner capture well. The attractant is placed in a region where it can be effectively detected by insects in flight, creating a localized zone of high attractant concentration that enhances lure effectiveness without requiring complex dispensing mechanisms or uniform distribution systems throughout the entire trap.
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 design improves pest extermination probability and reduces crop damage by ensuring light reaches lower areas, while supplying warm air to the crop roots, thereby reducing disease incidence and increasing production.
Implementation Method 1
Insects are attracted to the trap by a UV LED
Implementation Method 2
A fan blows the trapped insect away from the trap

AI summary
To improve the probability of exterminating pests and thereby to reduce damage to crops such as fruits and vegetables due to pests, an insect trap 100 according to the present invention includes: an attraction light source 210 that emits light for attracting insects; a mortar-shaped part 160 disposed vertically below the attraction light source and having an aperture whose diameter is narrowed toward vertically downward; a cylindrical part 170 disposed vertically below the mortar-shaped part 160 so as to extend from the mortar-shaped part 160; a fan 190 that generates an airflow in a direction sucking air from the aperture of the mortar-shaped part 160 into the cylindrical part 170; a long transparent cylindrical part 180 that is disposed vertically below the cylindrical part 170 and transmits light; and a net 310 disposed vertically below the long transparent cylindrical part 180 so as to trap insects.
