Crawling arthropod intercepting device and method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bed bugs have developed resistance to traditional pesticides, leading to a resurgence in infestations, and existing traps often require sticky substances or are ineffective in intercepting crawling arthropods on smooth surfaces.
Innovation Solution
A crawling arthropod intercepting device with a fibrous exterior surface for attracting and trapping bed bugs and other pests, featuring double pitfall traps with slick surfaces that prevent escape, and an optional killing agent for effective pest control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional pesticides are used to control bed bugs, then bed bug populations are reduced, but bed bugs develop resistance to the pesticides
Solution Approach 1:
The patent replaces chemical pesticide systems with a mechanical trapping system. The device uses a smooth interior surface that exploits bed bug locomotion mechanics - they cannot gain traction on the smooth surface and fall into the trap. This mechanical approach eliminates the resistance development problem inherent in chemical pesticides while maintaining control efficacy.
Solution Approach 2:
The smooth interior surface acts as an intermediary between the bed bug and the trap collection area. This intermediate surface with specific friction properties causes the bed bug to lose traction and fall into the trap, providing a reliable control method that does not depend on chemical effectiveness which degrades due to resistance.
2Productivity
If sticky substances are used in traps to capture crawling arthropods, then arthropods are trapped, but the traps become less effective over time and require replacement
Solution Approach 1:
The patent inverts the sticky substance approach by making the trapping surface permanent and durable (smooth non-sticky surface) while using a disposable collection container. The smooth surface maintains its trapping effectiveness indefinitely, eliminating the degradation problem of sticky substances, while the collected pests are disposed of in replaceable containers.
Solution Approach 2:
The patent changes the surface friction parameter from high (sticky) to low (smooth). This parameter change creates a permanent trapping mechanism where bed bugs continuously lose traction and fall into the collection area, maintaining consistent effectiveness without the degradation that occurs with sticky substances over time.
3Reliability
If a smooth surface is used to prevent bed bug climbing, then bed bugs cannot escape the trap, but bed bugs are attracted to rough surfaces
Solution Approach 1:
The patent applies different surface qualities to different parts of the device. The exterior uses a rough, fibrous material that attracts and facilitates bed bug climbing, while the interior uses a smooth surface that prevents escape. This local differentiation of surface properties resolves the contradiction between attraction and containment.
Solution Approach 2:
The patent inverts the conventional approach by making the interior surface smooth rather than rough. Instead of using a rough surface throughout to attract and hold pests, the smooth interior surface exploits the bed bug's inability to climb smooth surfaces, causing them to fall into the trap while the rough exterior provides attraction.
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 effectively intercepts and reduces bed bug populations, monitors infestations, and evaluates pest control efficacy by using observed bed bug responses to host cues and gravity, providing a mechanical barrier and trapping mechanism that is durable and reusable.
Implementation Method 1
A rough, vertical surface is attractive to bed bugs. To walk up a vertical surface, around a human body, or upside down under a bed, bed bugs use their hook-like tarsal claws to engage fibers and surface roughness
Implementation Method 2
Smooth glass containers are used routinely to contain laboratory colonies of crawling insects because they cannot gain traction on smooth surfaces
Implementation Method 3
crawling arthropods are trapped in the inner receptacle and/or outer receptacle as a result of being unable to climb out

AI summary
An intercepting device (e.g. a furniture coaster device) is placed under furniture (bed, sofa, chair. etc.), other climbable object, or the floor adjacent an object to intercept crawling arthropods and other crawling pests. The intercepting device can be used to monitor the presence of crawling arthropods and other crawling pests (such as bed bugs, ants, cockroaches, beetles, spiders, etc.), reduce pest numbers, and monitor efficacy of pest control procedures. The intercepting device includes pitfall trap surfaces that form multiple pitfall traps.
