Foldable Insect Trap with Pre-cut Suspension for Bait Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insect traps made of cardboard are not weather-resistant, and the mere use of sticky materials does not ensure optimal efficiency, with existing solutions for holding bait complicating the trap's structure and implementation.
Innovation Solution
A tubular insect trap with a triangular cross-section featuring a sheet with an adhesive upper face attached to the bottom wall, incorporating pre-cut suspension means that can support bait within the trap, allowing for better diffusion of attractive molecules and avoiding separate manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate suspension means are manufactured and attached to the trap, then the trap can hold bait effectively, but the structure and implementation become more complex
Solution Approach 1:
The suspension means are merged with the bottom wall by being pre-cut in its thickness, integrating two previously separate components (suspension means and bottom wall) into a single integrated structure, thereby simplifying manufacturing and reducing assembly steps
Solution Approach 2:
The suspension means are pre-cut in the bottom wall during manufacturing, preparing the trap for bait installation in advance. This preliminary action eliminates the need for separate attachment operations and simplifies field implementation
2Ease of operation
If the suspension means are completely pre-cut, then they can be easily separated for bait installation, but they may be lost during manufacturing or handling
Solution Approach 1:
The suspension means are pre-cut but remain captive in the bottom wall thickness during manufacturing, preparing them for use while preventing loss. The preliminary cutting is combined with a retention mechanism (adhesive sheet covering) that maintains reliability until deployment
Solution Approach 2:
The adhesive sheet acts as an intermediary that covers the pre-cut suspension means, preventing their loss during manufacturing and handling. It mediates between the need for pre-cutting (ease of operation) and the risk of loss (reliability), allowing easy separation at the point of use while maintaining security during storage and transport
3Reliability
If the bottom wall is made thicker to retain pre-cut suspension means, then the suspension means remain captive, but the trap becomes more expensive and heavier
Solution Approach 1:
The adhesive sheet serves as an intermediary retention mechanism that allows the bottom wall to remain thin while still preventing loss of pre-cut suspension means. It provides the necessary reliability without requiring increased material thickness, thereby maintaining manufacturing efficiency and cost-effectiveness
4Reliability
If the adhesive sheet covers the pre-cut suspension means, then the suspension means are protected from loss, but light may pass through the cut areas reducing effectiveness
Solution Approach 1:
The adhesive sheet acts as an intermediary that simultaneously addresses two requirements: it covers the pre-cut suspension means to prevent loss (reliability) and blocks light from passing through the cut areas (reducing light interference). The adhesive material itself serves as the light-blocking medium, eliminating the need for separate light-blocking structures
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 trap is more effective, inexpensive, and weather-resistant, with the pre-cut suspension means enhancing bait diffusion and ease of use while maintaining trap effectiveness and avoiding bait loss, and allowing for easy replacement of adhesive sheets without user contact.
Implementation Method 1
when the trap is used, said adhesive sheet blocking the light resulting from the cut
Implementation Method 2
the suspension of the bait allows it to better diffuse the attractive molecules in the surrounding atmosphere by being placed in the air currents crossing the trap

AI summary
The trap (1) has an inner space (2) defined by a peripheral wall (3) with a plain bottom lower wall (3a) and roof upper walls (3b, 3c). A sheet (4) with an adhesive upper face is arranged on the lower wall. A suspension unit (5) supports bait in the inner space of the trap. The suspension unit is precut in thickness of a part of the lower wall, which is covered by the sheet. The suspension unit is arranged for holding a bait reservoir (51) in the inner space of the trap, where the trap is realized in a foldable material foil.
