Ambulatory Pest Trapping Device Using Corrugated Intermediate Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ambulatory pest trapping devices face limitations in trapping efficiency per unit area due to the adhesion of the backs of pests, especially in confined spaces.
Innovation Solution
The ambulatory pest trapping device features a corrugated intermediate sheet with a tapered shape, sandwiched between upper and lower adhesive sheets, creating a space that traps pests as they enter, ensuring effective adhesion of both the backs and abdomens of the pests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a tapered space with adhesive ceiling surface is used to trap pest backs, then pests can be trapped by adhesion, but the trapping efficiency per unit area is limited
Solution Approach 1:
The invention transitions from a single-plane adhesive surface to a three-dimensional corrugated structure with multiple surfaces. The corrugated intermediate sheet creates upper and lower adhesive surfaces that face each other, forming a tapered space that traps pests from multiple dimensions simultaneously, thereby increasing trapping efficiency per unit area.
Solution Approach 2:
The adhesive trapping surface is segmented into multiple corrugated sections rather than a single flat surface. Each corrugation creates a separate tapered space with its own adhesive surfaces, allowing multiple trapping zones within a compact structure, which increases overall trapping capacity without proportionally increasing device footprint.
2Quantity of substance
If the ceiling surface is made adhesive to trap pest backs, then adhesion trapping is achieved, but the trapping capacity is limited by the confined space
Solution Approach 1:
The corrugated intermediate sheet is nested between the upper and lower sheets, creating a compact multi-layer structure. The tapered spaces are formed within this nested configuration, allowing multiple trapping zones to be contained within a small overall device volume while maintaining high trapping capacity.
Solution Approach 2:
The invention uses thin sheet structures (upper sheet, lower sheet, and corrugated intermediate sheet) to create the trapping device. These flexible thin films form the tapered spaces and adhesive surfaces without requiring bulky materials, enabling high trapping capacity in a compact form factor.
3Reliability
If adhesive sheets are used to trap pests, then effective adhesion is achieved, but pests with sharp leg tips can avoid capture by point contact
Solution Approach 1:
The invention adds a vertical dimension to the trapping mechanism by creating upper and lower adhesive surfaces facing each other. Pests entering the tapered space from the sides are trapped by adhesion to these vertical/overhead surfaces before they can use their sharp leg tips to avoid capture on horizontal surfaces, thereby improving trapping reliability.
