Effervescent CO2 Composition for Bed Bug Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bed bug monitoring and capture devices are ineffective due to the lack of a reliable and long-lasting attractant, with existing carbon dioxide generation methods being expensive, hazardous, or requiring water, which limits their effectiveness in attracting bed bugs.
Innovation Solution
A chemical composition that generates carbon dioxide using an effervescent agent, a solid acid, and a deliquescent agent, such as sodium bicarbonate and magnesium chloride hexahydrate, without water, to create a sustained release of carbon dioxide, attracting bed bugs to monitoring and capture devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pressurized carbon dioxide canisters are used to generate carbon dioxide, then sufficient carbon dioxide is generated to attract bed bugs, but the cost is expensive and the technology is complex
Solution Approach 1:
The patent replaces expensive, complex pressurized canisters with a simple, inexpensive chemical mixture of baking soda and citric acid that can be easily prepared and disposed of. The chemical reaction vessel is a simple container that can be discarded after use, eliminating the need for expensive reusable canister systems.
Solution Approach 2:
The patent replaces the mechanical pressurized canister system with a chemical reaction system. Instead of using mechanical pressure to release carbon dioxide, the system uses the chemical reaction between baking soda and citric acid to generate carbon dioxide gas in situ, simplifying the mechanical complexity.
2Quantity of substance
If dry ice is used to generate carbon dioxide, then carbon dioxide is produced to attract bed bugs, but it is dangerous to handle and not convenient to purchase
Solution Approach 1:
The patent replaces dangerous dry ice with inexpensive, safe-to-handle baking soda and citric acid that can be purchased in any grocery store. The materials are non-hazardous and can be easily stored and handled without special equipment or training.
Solution Approach 2:
The patent changes the physical state and temperature parameters from dry ice (solid carbon dioxide at -78°C) to room temperature chemical reagents. This eliminates the need for cold storage and special handling equipment while maintaining carbon dioxide generation capability.
3Quantity of substance
If yeast fermentation is used to generate carbon dioxide, then carbon dioxide is produced economically and safely, but the preparation procedure is complex and requires careful measurement and temperature control
Solution Approach 1:
The patent replaces the biological yeast fermentation process with a simple chemical reaction system. Instead of requiring living organisms, temperature control, and nutritional media, the system uses a direct chemical reaction between baking soda and citric acid that proceeds at room temperature without additional controls.
Solution Approach 2:
The patent uses simple, inexpensive chemical reagents that can be prepared in advance and stored, then activated by adding water right before use. The prepared mixture can be stored for extended periods and only requires a simple water addition step to activate carbon dioxide generation.
4Speed
If citric acid and sodium bicarbonate are mixed in water to generate carbon dioxide quickly, then carbon dioxide is generated rapidly, but the reaction is too quick and does not provide prolonged attraction
Solution Approach 1:
The patent prepares the chemical reaction mixture in advance and stores it in a stable, dormant state. The actual carbon dioxide generation is triggered by adding water right before use, allowing the device to be prepared beforehand and then activated when needed for prolonged attraction.
Solution Approach 2:
The patent structures the carbon dioxide generation to occur in sustained periods following water addition. The reaction continues to produce carbon dioxide over an extended period (several hours) after activation, providing prolonged attraction rather than a brief burst.
5Quantity of substance
If carbon dioxide is generated by chemical reaction in aqueous medium, then carbon dioxide is produced, but water is required which complicates the system and limits portability
Solution Approach 1:
The patent makes the system self-sufficient by including all necessary components (baking soda, citric acid, and water) in a single portable container. The water is already present in the container, eliminating the need for external water sources and making the system completely self-contained and portable.
