Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed bug control methods are ineffective in preventing infestation spread due to bed bugs' resistance to insecticides, hiding behavior, and the limited effectiveness of traditional traps, which often require multiple units and difficult installations.
Innovation Solution
A modular, inexpensive bed bug trap system using diatomaceous earth as a non-toxic insecticide, comprising interconnected plastic sections with inclined flanges that form a continuous boundary around a target area, enticing bed bugs to climb and fall into a U-shaped channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional insecticide-based traps are used, then bed bugs may be killed upon contact, but bed bugs have developed resistance to many commercial insecticides making them ineffective
Solution Approach 1:
The patent converts the harmful effect of diatomaceous earth (a natural substance that mechanically damages insect exoskeletons) into a beneficial pest control mechanism. Instead of using chemical insecticides to which bed bugs have developed resistance, the system employs diatomaceous earth particles that physically abrade and dehydrate bed bugs, bypassing their chemical resistance mechanisms. This principle transforms a naturally occurring harmful substance into an effective eco-friendly pest control solution.
Solution Approach 2:
The patent changes the mechanism of action from chemical (insecticide-based) to physical (mechanical abrasion and desiccation). By altering the fundamental parameter of how bed bugs are killed—from chemical toxicity to physical damage—the system overcomes bed bug resistance to commercial insecticides. The U-shaped channel design also changes the physical parameters of trap geometry to ensure bed bugs cannot escape after entering.
2Reliability
If multiple traditional traps are placed around the target area, then coverage may be improved, but the complexity of installation and configuration increases
Solution Approach 1:
The patent merges multiple traditional trap functions into a single continuous modular barrier system. Instead of placing separate discrete traps around the perimeter, the system uses interconnected modular sections that form a unified continuous boundary. This integration reduces the number of independent units needed while maintaining comprehensive coverage, as the modular sections work together as a cohesive barrier that bed bugs cannot bypass.
Solution Approach 2:
The patent segments the continuous barrier into modular, interchangeable sections that can be easily assembled and configured. Each modular section contains integrated diatomaceous earth treatment and U-shaped trapping geometry. This segmentation allows the system to adapt to different room sizes and layouts using fewer total units compared to traditional discrete traps, while maintaining ease of installation through simple modular connection.
3Reliability
If adhesive-based traps are used, then insects may be stuck upon contact, but bed bugs are not ensnared by ordinary adhesive-based insect traps
Solution Approach 1:
The patent replaces adhesive-based ensnarement with diatomaceous earth-based mechanical damage. Instead of relying on adhesive properties that bed bugs can avoid or resist, the system uses diatomaceous earth particles that cause physical damage to the bed bug exoskeleton upon contact. This conversion from adhesive to mechanical damage mechanism effectively overcomes bed bug behavior that avoids adhesive traps.
Solution Approach 2:
The patent substitutes the adhesive mechanism with a mechanical abrasion and desiccation mechanism. Diatomaceous earth particles physically scrape and damage the waxy coating on bed bug exoskeletons, causing them to lose moisture and die. This mechanical substitution bypasses bed bug behavioral adaptations to adhesive traps, as the physical damage mechanism cannot be avoided through behavior alone.
4Reliability
If attractants are used to lure bed bugs into traps, then insects may be drawn to the trap, but bed bugs are not attracted to bait materials used in typical cockroach and ant traps
Solution Approach 1:
The patent extracts the attractant component from the trap system entirely. Instead of using bait materials that bed bugs do not respond to, the system relies on the inherent behavior of bed bugs to seek out hiding places and the visual/structural attraction of the modular barrier design. The U-shaped channels and modular geometry create natural trapping zones that bed bugs enter seeking refuge, eliminating the need for attractants to which bed bugs have developed non-response.

AI summary
A segmented, floor-based trap system, which may be configured to delineate a floor area of arbitrary rectilinear geometry that is infested with crawling arthropods, particularly bed bugs, or an area to be protected from such infestation, thereby to intercept egress of such insects from such an area, or their ingress into it.The trap system comprises a plurality of trough-like linear segments containing a layer of mechanical insecticide, such as diatomaceous earth, and serving as an insect pitfall, and a plurality of linear and right-angled connectors, by which the linear segments may be connected continuously in fluid communication. A roughened, obtusely inclined flange extends from the top of each of the side walls of each linear segment to the floor, serving as a ramp leading insects to the smooth-walled pitfall. Foreshortened linear segments fitted to corner connectors in concave corners of the trap assembly preserve rectilinear alignment.
