Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current insecticides for bedbug control are toxic to non-target organisms, develop resistance over time, and have detrimental side effects, while essential oil formulations lack efficacy at lower concentrations.

Innovation Solution

A synergistic composition of geranium oil combined with other essential oils and natural surfactants in an aqueous formulation, which is eco-friendly, non-toxic, and effective against bedbugs, minimizing the need for repeated applications by maintaining effectiveness over time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If synthetic insecticides (DDT, pyrethroids) are used for bedbug control, then killing/repelling efficacy is improved, but toxicity to non-target organisms and harmful side effects increase

Engineering Contradiction:

Improvekilling/repelling efficacyVSAvoidtoxicity to non-target organisms

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by replacing synthetic insecticides with essential oils containing specific compounds (citronellal, geraniol, linalool, eugenol, thymol). This parameter change maintains insecticidal efficacy while eliminating the toxic side effects associated with synthetic chemicals like DDT and pyrethroids.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses composite essential oil formulations combining multiple oil components (geranium oil, citronella oil, eucalyptus oil, tea tree oil, lavender oil) to achieve synergistic effects. This composite approach provides effective bedbug control while maintaining safety for non-target organisms, as each essential oil component contributes to the overall efficacy without the harmful properties of synthetic insecticides.

Inventive Principle:

Principle #40Composite materials

2Object-affected harmful factors

If essential oil formulations are used at lower concentrations, then safety and eco-friendliness are improved, but killing/repelling efficacy decreases

Engineering Contradiction:

Improvesafety for humans and non-target organismsVSAvoidkilling/repelling efficacy

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent merges multiple essential oils into a synergistic formulation where geranium oil (providing citronellal, geraniol, linalool) is combined with citronella oil, eucalyptus oil, tea tree oil, and lavender oil. This combination allows the use of lower concentrations of each individual oil while maintaining or enhancing overall efficacy through synergistic interactions between the different oil components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The composite essential oil formulation enables effective bedbug control at lower concentrations by leveraging the complementary properties of different essential oils. The synergistic combination maintains high efficacy while ensuring safety for humans and non-target organisms, as each component contributes to the overall bioactivity without requiring high individual concentrations.

Inventive Principle:

Principle #40Composite materials

3Reliability

If repeated applications of insecticides are performed, then control effectiveness is maintained, but loss of time and increased substance usage occur

Engineering Contradiction:

Improvecontrol effectivenessVSAvoidtime for repeated applications

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The essential oil formulation provides sustained control effectiveness by maintaining active concentrations over extended periods. The synergistic combination of essential oils with different degradation rates and modes of action ensures continuous bioactivity, reducing or eliminating the need for repeated applications and the associated time loss and substance consumption.

Inventive Principle:

Principle #20Continuity of useful action
