Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pest control aerosol compositions are used, then basic pest control function is provided, but excellent pest control effect particularly for flying pests is not achieved
Solution Approach 1:
The patent changes the physical and chemical parameters of the composition by selecting an organic solvent with a specific boiling point range (220°C or higher) and controlling its content at 10 to 30 wt%. This parameter optimization enables the composition to maintain stability in aerosol form while achieving excellent pest control effect, particularly against flying pests, thereby resolving the contradiction between basic functionality and specialized effectiveness.
2Stability of the object's composition
If an organic solvent with high boiling point is used to improve stability, then aerosol composition stability is improved, but rapid knock-down effect on pests may be compromised
Solution Approach 1:
The patent optimizes the boiling point parameter of the organic solvent to be 220°C or higher, which ensures sufficient thermal stability for aerosol storage and application while maintaining appropriate volatility for rapid pest knock-down. The controlled concentration range (10-30 wt%) further balances stability and effectiveness, resolving the contradiction between composition stability and action speed.
Solution Approach 2:
The patent creates a composite aerosol system combining the specific organic solvent (with boiling point ≥220°C), the pest control compound, and propellant in optimized proportions. This composite formulation achieves synergistic effects where the solvent provides both stability and appropriate volatility, resolving the contradiction between maintaining composition integrity and enabling rapid pest control action.
