Solution Overview

Problem

The overuse of synthetic pesticides poses significant threats to human health and the environment, necessitating the development of environmentally benign and effective alternatives for controlling insect pests.

Innovation Solution

Compositions containing compounds of formula 1, which include methyl benzoate and other alkyl benzoates, optionally with surfactants and carriers, are used to treat objects or areas to kill insects, leveraging their insecticidal properties through contact and fumigant actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If synthetic pesticides are used to control insect pests, then pest control effectiveness is improved, but human health safety and environmental sustainability deteriorate

Engineering Contradiction:

Improvepest control effectivenessVSAvoidhuman health safety and environmental impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by using naturally occurring plant toxins (such as pyrethrins, rotenone, azadirachtin) instead of synthetic pesticides, while maintaining effective pest control through optimized formulation parameters including particle size, concentration, and delivery mechanism

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs composite material formulations combining multiple natural toxin components with biodegradable carriers and adjuvants to enhance pest control effectiveness while maintaining environmental safety, creating a composite pesticide product that leverages synergistic effects of different natural compounds

Inventive Principle:

Principle #40Composite materials

2Productivity

If conventional synthetic pesticides are used, then insect pest mortality is increased, but species diversity and ecosystem health deteriorate

Engineering Contradiction:

Improveinsect pest mortality rateVSAvoidimpact on species diversity and ecosystem

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent applies localized quality control by formulating pesticides with specific toxin profiles tailored to target particular pest species while being selective in their mode of action, thereby achieving high mortality rates for target pests while minimizing impact on non-target species and ecosystem biodiversity

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent utilizes biodegradable and environmentally transient natural toxin formulations that break down quickly in the environment after performing their pest control function, replacing persistent synthetic pesticides with short-lived natural compounds that do not accumulate in ecosystems

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
