Automobile Pest Extermination Device Using Heated Air Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pest extermination methods for automobiles, such as fumigation, are time-consuming, costly, and can damage precision machinery, making them unsuitable for large-scale export treatments, especially for vehicles like those from Japan to New Zealand, where invasive species like the brown marmorated stink bug pose significant ecological risks.
Innovation Solution
An automobile high-temperature pest extermination device featuring a treatment chamber with a circulation fan device, heating members, and rectification members that circulates and distributes heated air to maintain uniform temperatures, allowing for efficient pest control without fumigation agents, capable of treating multiple vehicles in series or parallel configurations with centralized management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fumigation using agents such as alkyl iodide is performed to exterminate pests, then pest extermination effectiveness is improved, but treatment time increases to several days and costs increase due to agent usage
Solution Approach 1:
The patent replaces the chemical fumigation system with a thermal treatment system. Instead of using chemical agents (alkyl iodide) to kill pests, the invention uses heated air circulation to raise the temperature inside the vehicle to lethal levels for pests. This substitution eliminates the need for chemical agents and reduces treatment time from several days to a few hours, while maintaining pest extermination effectiveness.
Solution Approach 2:
The patent changes the physical parameter of temperature to achieve pest extermination. By controlling and raising the internal temperature of the vehicle to a specific range (typically 50-70°C) and maintaining it for a predetermined time, the system achieves effective pest kill without chemicals. This parameter-based approach transforms the treatment process from chemical-dependent to physics-based, reducing both time and cost.
2Reliability
If fumigation agents are used to exterminate pests, then pest control is achieved, but the agents can adversely affect various components of the automobile and may remain in the air conditioner filter causing unpleasant odors
Solution Approach 1:
The patent replaces the chemical fumigation system with a thermal treatment system. Instead of using chemical agents (alkyl iodide) to kill pests, the invention uses heated air circulation to raise the temperature inside the vehicle to lethal levels for pests. This substitution eliminates the need for chemical agents and reduces treatment time from several days to a few hours, while maintaining pest extermination effectiveness.
Solution Approach 2:
The patent converts the potentially harmful high-temperature condition into a beneficial pest-killing mechanism. By carefully controlling the temperature parameters, the system uses heat - which could potentially damage vehicle components - as a precise and effective tool for pest extermination. The controlled thermal environment kills pests while the absence of chemical agents prevents contamination of vehicle systems like air conditioners.
3Reliability
If fumigation treatment is performed for a large number of exported vehicles, then pest extermination is achieved, but enormous treatment facilities are required in restricted areas such as harbors
Solution Approach 1:
The patent divides the treatment system into modular, manageable units. Each vehicle is treated independently in a controlled chamber or enclosed space, allowing parallel processing of multiple vehicles. This segmentation enables high throughput by treating vehicles sequentially or simultaneously without requiring an enormous centralized facility, making the system suitable for restricted areas like harbors where space is limited.
Solution Approach 2:
The patent employs dynamic temperature control and air circulation systems that can be rapidly adjusted for each vehicle. The heated air circulation system quickly raises and maintains temperature throughout the vehicle interior, enabling fast treatment cycles. This dynamic control allows the system to efficiently handle large numbers of vehicles by minimizing treatment time per vehicle while ensuring complete pest extermination.
