Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pest control methods, including chemical pesticides and heat treatments, face challenges such as environmental contamination, toxicity risks, development of pest resistance, and inefficiency, particularly in agriculture and household settings, necessitating a safer and more sustainable alternative.
Innovation Solution
An aqueous biocidal composition comprising polyalkyleneoxide modified heptamethyl tri-siloxane and dimethyl sulfoxide, which reduces surface tension to enhance penetration and suffocate pests without using toxic chemicals, thereby minimizing environmental impact and resistance development.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical pesticides are used to control pests, then pest elimination effectiveness is improved, but environmental contamination and toxicity risks increase
Solution Approach 1:
The patent changes the chemical parameters of biocidal compositions by using environmentally benign solvents (aqueous-based formulations) and combining multiple active ingredients at optimized concentrations to achieve effective pest control without toxic chemical residues
Solution Approach 2:
The patent employs composite biocidal formulations combining multiple active ingredients (such as neem extracts, essential oils, and biocontrol agents) with compatible surfactants and carriers to create synergistic effects that enhance pest elimination while maintaining environmental safety
2Object-affected harmful factors
If heat treatments are used for pest control, then chemical-free treatment is achieved, but cost and labor intensity increase
Solution Approach 1:
The patent replaces mechanical/thermal pest control methods (heat treatments) with chemically-based but environmentally safe alternatives using plant-derived biocontrol agents and natural extracts that achieve pest elimination through biological mechanisms rather than thermal energy input
3Reliability
If single biocide composition is used repeatedly, then initial pest control effectiveness is achieved, but pest resistance develops over time
Solution Approach 1:
The patent merges multiple biocidal active ingredients with different modes of action into a single composite formulation, preventing pest resistance by simultaneously targeting multiple physiological pathways and reducing the likelihood of adaptive resistance development
Solution Approach 2:
The patent recommends periodic rotation of different biocidal formulations and application intervals to prevent resistance buildup, alternating between compositions with different active ingredients to maintain long-term efficacy
