Solution Overview

Problem

Existing pest control methods, particularly chemical pesticides, are often ineffective, toxic, and contribute to pesticide resistance in pests, while traditional botanical biochemicals can be inconsistent and difficult to deliver effectively.

Innovation Solution

A device comprising a substrate impregnated with a composition of neem oil, a polar aromatic solvent, and diluents, along with a removable peel strip to control the release of vapors, is used to control pests by releasing pesticidal vapors that are effective and safer for desirable organisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional chemical pesticides are used, then pest control effectiveness is improved, but toxicity to desirable organisms increases

Engineering Contradiction:

Improvepest control effectivenessVSAvoidtoxicity to desirable organisms

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the physical state parameter of the pesticide from liquid/solid contact form to vapor phase, enabling pests to be controlled through inhalation while reducing direct toxic contact with beneficial organisms. The vapor delivery system transforms the application method, maintaining effectiveness against pests while lowering harmful effects on non-target species.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The vapor delivery device acts as an intermediary between the pesticide composition and the pests, controlling the release and distribution of active ingredients. This intermediary system allows for targeted vapor delivery to infested areas while limiting exposure of beneficial organisms, thus resolving the contradiction between effectiveness and safety.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If conventional liquid spray pesticides are used, then direct contact pest control is improved, but penetration into hidden spaces deteriorates

Engineering Contradiction:

Improvedirect contact effectivenessVSAvoidcoverage of hidden spaces

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The patent employs vapor phase delivery (a pneumatic approach) to transport pesticide active ingredients into hidden and hard-to-reach spaces where liquid sprays cannot penetrate. The vapor naturally disperses into crevices, voids, and concealed areas, providing both contact and respiratory exposure to pests in locations previously inaccessible to conventional liquid applications.

Inventive Principle:

Principle #29Pneumatics and hydraulics

3Object-affected harmful factors

If traditional botanical biochemicals are used, then natural pest control is improved, but delivery consistency deteriorates

Engineering Contradiction:

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The vapor delivery device serves as a reliable intermediary that ensures consistent delivery of botanical biochemicals. The controlled vapor release mechanism maintains uniform concentration and distribution of the natural active ingredients, overcoming the inconsistency problem associated with traditional botanical applications while preserving their safety profile.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If conventional pesticides are applied, then pest control coverage is improved, but damage to valuable materials increases

Engineering Contradiction:

Improvepest control coverageVSAvoiddamage to valuable materials

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the physical state of pesticide delivery from liquid to vapor, allowing for comprehensive pest control coverage while minimizing damage to valuable materials. Vapors can be controlled to dissipate after treatment, unlike liquids that may leave residues or cause staining, thus maintaining coverage effectiveness while reducing harmful effects on furniture, electronics, and other valuables.
