Solution Overview
Problem
Existing pest control materials coated with pyrethroid insecticides lack sufficient performance in controlling pests effectively.
Innovation Solution
A pest control material comprising 5-chloro-4-ethyl-6-[2-(4-trifluoromethylphenyl)ethylamino]pyrimidine on a polyester multifilament base material, either in net or mosquito bed net form, with a concentration of 0.1 to 10% by mass, providing an excellent control effect against pests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pyrethroid insecticides are coated on the surface of pest control materials, then the materials can control pests, but the control performance is insufficient
Solution Approach 1:
The patent changes the chemical parameter from conventional pyrethroid insecticides to a specific pyrimidine compound (5-chloro-4-ethyl-6-[2-(4-trifluoromethylphenyl)ethylamino]pyrimidine), which exhibits superior insecticidal activity and resistance-breaking properties, thereby resolving the insufficient control performance issue
Solution Approach 2:
The patent combines the pyrimidine insecticide with specific carrier materials and adjuvants to create a composite pest control material system, where the synergistic interaction between components enhances the overall effectiveness and durability of pest control
2Duration of action of stationary object
If conventional pest control materials are used, then they provide basic pest control, but they lack sufficient performance and residual efficacy
Solution Approach 1:
The patent modifies the chemical stability and binding parameters of the insecticide by selecting a specific pyrimidine compound with enhanced molecular structure, which provides both prolonged residual efficacy and maintained control effectiveness over time
Solution Approach 2:
The patent ensures continuous pest control action through the sustained release and prolonged activity of the pyrimidine insecticide on the material surface, maintaining effective concentrations over extended periods rather than requiring frequent reapplication
