Bed Bug Interceptor with Fibrous Climb Surface and Slick Pitfall Traps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bed bugs have developed resistance to various 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 bed bugs and double pitfall traps with slick surfaces to trap them, preventing escape and allowing for optional killing agents in the traps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pesticides are used to control bed bugs, then bed bug populations are reduced, but bed bugs develop resistance to pesticides over time
Solution Approach 1:
The patent replaces chemical pesticide systems with a mechanical trapping system. The intercepting device uses physical barriers (slick surfaces) and mechanical traps to capture bed bugs without chemical intervention, thereby avoiding resistance development while maintaining control effectiveness.
Solution Approach 2:
The patent introduces an intermediary trapping mechanism between the bed bug and its environment. The intercepting device acts as a mediator that passively captures bed bugs through its structural design (rough exterior for attraction, slick interior for trapping), eliminating the need for direct pesticide application.
2Reliability
If smooth surfaces are used in traps, then bed bugs cannot climb out, but bed bugs are repelled by smooth surfaces and avoid the trap
Solution Approach 1:
The patent applies different surface qualities to different parts of the same device. The exterior surface has a rough texture to attract and facilitate bed bug climbing, while the interior trap surface is smooth to prevent escape. This local differentiation of surface properties resolves the contradiction between attraction and trapping.
Solution Approach 2:
The patent inverts the conventional approach by making the attractive surface (exterior) rough and the trapping surface (interior) smooth. Instead of using a uniformly smooth surface that repels bed bugs, the device uses surface texture inversion to simultaneously achieve attraction and effective trapping.
3Productivity
If sticky substances are used in traps, then bed bugs are trapped effectively, but the trap requires frequent maintenance and replacement
Solution Approach 1:
The patent replaces sticky chemical substances with a mechanical trapping mechanism. The slick surface trap uses physical properties (surface friction) rather than adhesive chemicals, making the trap reusable and durable without requiring frequent replacement of sticky materials.
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
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
The basic insect pitfall trap outdoors comprises a container (a jar, can, or other container) buried in the soil so that the top edge of the container is at the same level of soil surface or just below the soil surface. Crawling insects and spiders fall into the trap and are unable to escape

AI summary
An intercepting device (e.g. a furniture coaster device) is placed under furniture (bed, sofa, chair. etc.), other climable 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.
