Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anesthetic injection and incineration methods are used to eradicate hornet nests, then hornet population control is achieved, but the process becomes complex, polluting, and risky with potential for insect escape
Solution Approach 1:
The patent replaces the mechanical/chemical system of anesthetic injection and incineration with an electromagnetic field-based system. A magnetron generates microwave electromagnetic waves (2.45 GHz) that are directed into the hornet nest cavity through a waveguide, causing thermal heating and incapacitation of hornets without requiring physical nest destruction or chemical substances.
Solution Approach 2:
The patent introduces an intermediary detection system using optical sensors and microcontrollers to detect hornet presence and trigger the electromagnetic wave emission automatically. This intermediary system eliminates the need for manual intervention and complex operational procedures associated with traditional methods.
2Object-affected harmful factors
If traditional incineration methods are used to destroy hornet nests, then hornets are eliminated, but environmental pollution and worker safety risks increase
Solution Approach 1:
The patent converts the harmful electromagnetic radiation into a beneficial tool for hornet control. The microwave electromagnetic waves, which can be harmful in uncontrolled settings, are precisely directed and controlled to heat and incapacitate hornets within the nest cavity, transforming a potential hazard into an effective and clean eradication method.
Solution Approach 2:
The patent creates a controlled electromagnetic environment within the metal enclosure that isolates the treatment process from the external environment. The waveguide and enclosure structure contain the electromagnetic waves, preventing environmental pollution and protecting workers from exposure, while effectively treating the hornets inside.
3Productivity
If manual nest destruction is used to control hornets, then population control is achieved, but escaped insects may contribute to species expansion
Solution Approach 1:
The patent employs preliminary detection action using optical sensors that detect hornet presence and movement within the nest cavity before electromagnetic wave emission begins. This preliminary detection ensures that all hornets are identified and targeted, preventing any escape and ensuring complete eradication before the population control process concludes.
Solution Approach 2:
The patent implements a feedback control system where optical sensors continuously monitor hornet presence and movement, and the microcontroller adjusts the electromagnetic wave emission accordingly. The system provides visual feedback through LEDs indicating detection status and treatment progress, ensuring complete eradication and preventing insect escape.
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 traps and incapacitates hornets without the risks and inefficiencies of traditional methods, ensuring effective population control with minimal environmental impact.
Implementation Method 1
a source S of electromagnetic waves capable of generating electromagnetic waves inside the cavity as soon as a hornet is detected in the cavity
Implementation Method 2
The dimensions of the waveguides are such that, on the one hand, the hornets are capable of penetrating into the cavity 2 and, on the other hand, the electromagnetic waves, when they are present in the cavity, cannot escape from the cavity (cutoff frequency). In fact, the cavity provided with the opening means 3 behaves like a microwave oven and the frequency of the electromagnetic waves is preferably chosen substantially equal to 2.45 GHz.
Implementation Method 3
The dimensions of the waveguides are such that, on the one hand, the hornets are capable of penetrating into the cavity 2 and, on the other hand, the electromagnetic waves, when they are present in the cavity, cannot escape from the cavity (cutoff frequency).
Implementation Method 4
the means capable of detecting the presence of at least one hornet in the cavity comprise optical means which create a sheet of light in the cavity and electronic means which deliver a control signal capable of triggering the source of electromagnetic waves as soon as a hornet crosses the sheet of light.
