Self-Sealing Membrane Bait Station for Bed Bug Eradication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bed bug infestations are difficult to eradicate due to their ability to hide in small spaces, transport via objects, and long survival periods without feeding, making existing methods ineffective in eliminating them once established.
Innovation Solution
A self-sealing membrane bait station containing a non-toxic liquid bait with a pH of 6-8, comprising sodium chloride and optional active ingredients like boric acid, heated to mimic human body temperature, which attracts and kills bed bugs without requiring direct contact with the membrane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional insecticides are used to eradicate bed bugs, then some bed bugs may be killed, but bed bugs develop resistance and infestations are not eliminated
Solution Approach 1:
The patent changes the chemical parameters of the bait by using a salt solution with specific pH levels (6-8) and composition rather than conventional insecticides. This parameter change makes the bait ineffective for developing resistance while still being lethal to bed bugs when consumed
Solution Approach 2:
The patent employs a disposable bait station system where the bait is consumed and the station is replaced. This eliminates the need for persistent chemical residues and prevents resistance development through continuous introduction of fresh, non-resistant bait compositions
2Reliability
If liquid bait is made toxic to kill bed bugs, then bed bugs are killed, but the bait becomes harmful to humans
Solution Approach 1:
The patent uses a self-sealing membrane as an intermediary between the human-safe salt solution and the bed bug. The membrane allows bed bugs to pierce and consume the bait while preventing human contact with the liquid, making the harmless salt solution effective against bed bugs without posing risks to humans
Solution Approach 2:
The patent creates different safety zones: the liquid bait is safe for humans but lethal to bed bugs when consumed. The self-sealing membrane creates a localized access point that is pierceable by bed bugs but not by humans, allowing the same substance to have different effects based on who or what accesses it
3Loss of information
If bed bugs are monitored and tracked, then infestation levels can be assessed, but detection methods are difficult due to bed bugs hiding in small spaces
Solution Approach 1:
The patent incorporates UV-reactive substances in the bait or station components that fluoresce under ultraviolet light. This color/visibility change allows easy detection and tracking of bed bug activity without requiring direct visualization of the hidden insects themselves
Solution Approach 2:
The bait station serves as both a killing mechanism and a monitoring device. Bed bugs must interact with the station to feed, and this interaction leaves detectable traces (such as UV-reactive markings or consumption indicators), allowing the system to automatically provide monitoring information without external intervention
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 bait station effectively attracts and kills bed bugs, reducing the risk of infestation and re-infestation by mimicking human body heat and using lethal yet harmless to humans sodium chloride solutions, while allowing monitoring of insect activity through visual or UV detectable indicators.
Implementation Method 1
The bait station includes a heating element, the heating element heating the liquid bait contained within the membrane contained within the housing
Implementation Method 2
the invention provides a device for exterminating blood-feeding insects, comprising a self-sealing membrane, the membrane containing a solution toxic to the blood-feeding insects
Data Source
AI summary
A device for controlling blood-feeding insects is disclosed. The device includes a membrane containing a solution suitable for consumption by blood-feeding insects wherein the solution is comprised of a base, the base selected from the group consisting of up to 70 wt % NaCl in water, phosphate buffer, citric acid in water, and sodium lauryl sulfate in water; and wherein the solution has a pH of between about 6 and 8. An additional active ingredient may be added to the solution. The solution may be referred to as liquid bait. The membrane is suitable for blood-feeding insects to pierce or puncture in order to feed. A method of exterminating or controlling blood feeding insects is also disclosed along with novel bait solutions.
