Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If combustion of propane is used to generate CO2, then CO2 attractant is produced, but pollutants are generated and catalytic converter contaminates over time
Solution Approach 1:
The invention changes the combustion parameters by controlling the air-to-fuel ratio to create oxygen-deficient conditions. This parameter change transforms the complete combustion process into partial combustion, producing CO and other partial oxidation products instead of CO2 and water. The controlled incomplete combustion eliminates the need for catalytic converters while generating effective attractants.
Solution Approach 2:
Instead of using complete combustion to produce CO2 and then purifying it through a catalytic converter, the invention inverts the approach by using incomplete combustion to directly produce the desired attractant mixture containing CO, CO2, and other partial oxidation products. This eliminates the purification step and its associated problems.
2Productivity
If open flame combustion is used, then CO2 is generated quickly, but safety risks increase due to high temperatures
Solution Approach 1:
The invention replaces the mechanical/open flame combustion system with a controlled chemical reaction system. By using a catalyst to facilitate the oxidation of organic substances at lower temperatures and controlling the air supply to maintain oxygen-deficient conditions, the system achieves CO and CO2 generation without open flames, thereby eliminating the associated safety hazards.
Solution Approach 2:
The invention introduces a catalyst as an intermediary substance to facilitate the oxidation reaction. The catalyst enables the reaction to proceed at lower temperatures and with better control, replacing the need for open flame combustion while maintaining effective attractant production.
3Productivity
If complete oxidation is used, then CO2 is produced efficiently, but attractive effect is reduced compared to partial oxidation products
Solution Approach 1:
The invention applies partial oxidation rather than complete oxidation by deliberately limiting the oxygen supply. This partial action produces a mixture of CO, CO2, and other partial oxidation products that together create a more effective attractant than pure CO2 would provide, while still maintaining efficient conversion of the organic substance.
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 method and device produce CO2 attractant mixtures that are safer, more efficient, and more attractive to blood-sucking arthropods, reducing the need for open flames and minimizing pollution, while allowing for targeted attraction and increased catching rates compared to conventional methods.
Implementation Method 1
the substance is reacted in an oxidation process in a targeted manner... The oxidation process of the organic substance is in particular a catalytic oxidation process
Implementation Method 2
For the generation of the CO2 at least one liquid or solid organic substance is reacted in an oxidation process
Implementation Method 3
the at least one liquid or solid organic substance is evaporated before the oxidation process, in particular before the catalytic oxidation process, and mixed with air to form a reaction gas mixture
Implementation Method 4
In addition to CO2, H2O and heat at least one other partial oxidation product is generated. This partial oxidation product causes an amplification of the particular luring effect of the attractant mixture. Also, the heat generated during the oxidation process represents another positive factor for the attraction of the insects

AI summary
The invention relates to a method for producing CO2 for attracting bloodsucking arthropods (2). In this method, at least one liquid or solid organic substance (11) is reacted in an oxidation process in a targeted manner, one portion completely and another partially, thus forming, in addition to CO2, H2O and heat, at least one further partial oxidation product (P). The invention further relates to a device (1a, 1b) for generating CO2, said device (1a, 1b) comprising a storage means (10) for at least one liquid or solid organic substance (11) and an evaporation module (14) for the liquid or solid organic substance (11). The device (1a, 1b) comprises a reactor module (16) for the controlled oxidation and partial oxidation of the at least one liquid or solid organic substance (11); a control unit (80); and means (13, 18, 21, 22, 26) for regulating the oxidation and partial oxidation process. The means (13, 18, 21, 22, 26) for regulating the oxidation and partial oxidation process can be regulated via the control unit (80), hence allowing defined reaction conditions to be set in the reactor module (16) for the targeted control of the oxidation and partial oxidation process.
