Solution Overview

Problem

Current pest extermination methods for automobiles, such as fumigation, are inefficient and can damage precision machinery, are time-consuming, and require large facilities, making it difficult to effectively treat a large number of vehicles for export, especially due to the challenges posed by invasive species like the brown marmorated stink bug.

Innovation Solution

An automobile high-temperature pest extermination device that uses a circulation fan device and heating member to circulate and distribute heated air within a treatment chamber, allowing for efficient pest extermination without fumigation agents, with the ability to connect multiple chambers in series or parallel to treat multiple vehicles efficiently and manage operations centrally.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fumigation using chemical agents is performed to exterminate pests, then pest extermination effectiveness is improved, but harmful effects on automobile components and unpleasant odors occur

Engineering Contradiction:
Improvepest extermination effectivenessVSAvoiddamage to automobile components and unpleasant odors
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical fumigation with a thermal treatment system using circulation fans and heating members to apply high temperature to exterminate pests. This substitution eliminates chemical agents entirely, achieving pest extermination through physical thermal energy while avoiding all harmful chemical effects on automobile components and air quality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the parameter of pest extermination from chemical concentration to temperature. By controlling temperature parameters (heating to high temperature and maintaining it), the system achieves effective pest extermination without chemical agents, thereby eliminating the harmful side effects associated with chemical fumigation.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If fumigation treatment is performed to exterminate pests, then pest extermination is achieved, but treatment time increases to several days

Engineering Contradiction:
Improvepest extermination effectivenessVSAvoidtreatment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces slow chemical fumigation processes with rapid thermal treatment using circulation fans and heating members. This substitution reduces treatment time from several days to a much shorter duration, as high temperature can be applied immediately and uniformly throughout the chamber, accelerating the pest extermination process significantly.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The circulation fans continuously circulate heated air throughout the treatment chamber, ensuring continuous and uniform thermal exposure to all pests. This continuous action eliminates the prolonged waiting periods required by chemical fumigation, maintaining effective pest extermination while significantly reducing overall treatment time.

Inventive Principle:
Principle #20Continuity of useful action

3Quantity of substance

If fumigation treatment is performed on a large number of automobiles, then pest extermination coverage is improved, but facility size and costs increase enormously

Engineering Contradiction:
Improvenumber of automobiles treatedVSAvoidfacility size and treatment costs
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent divides the treatment system into modular components: multiple independent treatment chambers, circulation fans, and heating members. This segmentation allows the facility to treat multiple automobiles simultaneously in separate chambers, increasing throughput without requiring a single enormous facility, thereby reducing overall complexity and cost while maintaining high treatment capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The treatment chambers are designed to accommodate automobiles of various sizes and configurations, providing universal applicability. The circulation fan and heating member system serves multiple functions: heating air, circulating it uniformly, and controlling temperature. This multi-functionality reduces the number of separate systems needed, simplifying facility design and reducing costs while enabling treatment of large numbers of diverse vehicles.

Inventive Principle:
Principle #6Universality (Multi-functionality)
