Insect Trap Mesh Inlet for Escape-Resistant Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect traps with large openings often fail to capture insects effectively as they can escape through the opening without contacting the adhesive sheet.
Innovation Solution
The insect trap design includes a partially closing opening with a light-transmissive mesh that allows the attracting medium to pass through while blocking insects, featuring a tubular shape with a circulating route and a guide part to direct insects to a capturing part, enhancing capture efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening is made large to allow insects to easily enter the housing, then the ease of operation is improved, but the reliability of insect capture deteriorates because insects can escape through the opening
Solution Approach 1:
The opening is segmented into two functional zones: an upper opening area for insect entry and a lower mesh area for insect retention. This segmentation allows the same structure to simultaneously provide easy access for insects while preventing their escape, resolving the contradiction between ease of entry and capture reliability.
Solution Approach 2:
The mesh structure acts as an intermediary element within the opening that allows attracting light to pass through while blocking insects. This intermediary component enables the opening to fulfill dual functions: maintaining attractiveness for insects while serving as a retention barrier, thus resolving the contradiction between ease of entry and capture reliability.
2Ease of operation
If the opening is made large to improve insect entry, then the ease of operation is improved, but the loss of attracting medium deteriorates as more light escapes without capturing insects
Solution Approach 1:
The opening is divided into an upper region that allows light escape and a lower mesh region that retains both light and insects. This segmentation enables the attracting medium to be effectively utilized by preventing its loss through the lower portion while maintaining adequate opening size for insect entry.
Solution Approach 2:
The mesh serves as an intermediary that selectively allows the attracting medium (light) to pass through while blocking insects. This reduces the loss of attracting medium by containing it within the housing where it can continue to attract insects, while still permitting sufficient light to escape to maintain attractiveness.
3Reliability
If the mesh opening is made smaller to prevent insect escape, then the reliability of insect capture is improved, but the ease of operation deteriorates as insects have difficulty entering
Solution Approach 1:
The opening is segmented vertically with the upper portion remaining open and larger for easy insect entry, while the lower portion uses mesh for retention. This segmentation allows the structure to simultaneously provide easy access and reliable capture without compromising either function.
Solution Approach 2:
Different regions of the opening have different qualities: the upper region has open structure for ease of entry, while the lower region has mesh structure for reliable capture. This local differentiation of properties allows each region to optimize its specific function, resolving the contradiction between ease of entry and capture reliability.
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 insect trapping performance by retaining insects within the trap without degrading the attracting effect, increasing capture efficiency and allowing for clear imaging of captured insects.
Implementation Method 1
an attracting part for generating an attracting medium for attracting the insect into the collecting part; the attracting part is configured to emit light as the attracting medium
Implementation Method 2
the closing part is configured to allow the attracting medium to pass therethrough from the inside of the collecting part to the outside of the collecting part; the closing part is configured to be light transmissive

AI summary
An insect trap includes a collecting part having a space therein for collecting an insect to be captured; an attracting part for generating an attracting medium for attracting the insect into the collecting part; and a capturing part for capturing the insect inside the collecting part. The collecting part has an inlet through which the insect passes into the collecting part, and the inlet has: an opening for communication between inside and outside the collecting part; and a closing part that partially closes the opening and configured to allow the attracting medium to pass therethrough from the inside of the collecting part to the outside of the collecting part.
