Pointed Adhesive Protrusions for Ambulatory Pest Trapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pest trapping devices have insufficient adhesive strength due to a small contact area between the pest's legs and the adhesive surface, making it difficult to trap ambulatory pests like spider mites effectively.
Innovation Solution
The ambulatory pest trapping device features pointed protrusions with a tip radius of curvature between 0.001 mm to 1.0 mm, which are covered with adhesive, allowing for increased contact area and improved trapping efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a flat adhesive surface is used to trap pests, then the device structure is simple, but the contact area between pest legs and adhesive is small resulting in insufficient adhesive strength
Solution Approach 1:
The patent applies curvature by transforming the flat adhesive surface into a three-dimensional protruding structure with a rounded apex. This curved protrusion increases the contact area with pest legs through its surface geometry, while the rounded shape allows the adhesive to be distributed over a larger area that contacts the pest, thereby improving adhesive strength without requiring complex mechanical structures
2Productivity
If the adhesive surface area is increased to improve trapping efficiency, then more pests can be trapped, but the device size and material consumption increase
Solution Approach 1:
The patent transitions from a two-dimensional flat adhesive surface to a three-dimensional protruding structure. This dimensional change allows the adhesive to contact pests from multiple surfaces (side surface and apex) of the protrusion, effectively increasing the functional contact area without proportionally increasing the planar footprint or total adhesive material required
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 reliably traps ambulatory pests by ensuring the adhesive surface effectively adheres to the pest's abdomen, improving trapping efficiency and overcoming the limitations of previous devices.
Implementation Method 1
a pointed protrusion at least part of which is covered with an adhesive
