Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pheromone compositions for non-human mammals, particularly those used to address stress and anxiety, often rely on petroleum-derived solvents that are not biodegradable and can have safety concerns, with variable diffusion efficiency and stability.
Innovation Solution
A pheromone composition utilizing a biodegradable synthetic dibasic ester solvent with a vapor pressure between 1 and 10 Pa and a flash point greater than or equal to 95°C, which includes a mixture of fatty acids or their derivatives, specifically designed for diffusion in ambient air using a diffusion device, offering improved stability and reduced energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If petroleum-derived solvents are used in pheromone compositions, then the composition can be effectively delivered to non-human mammals, but the environmental impact increases and biodegradability decreases
Solution Approach 1:
The patent changes the chemical composition parameters of the carrier solvent from petroleum-derived hydrocarbons to biodegradable synthetic dibasic esters. This parameter change maintains the solvent's ability to deliver pheromones effectively while improving biodegradability and reducing environmental impact, directly resolving the contradiction between delivery effectiveness and environmental harm.
Solution Approach 2:
The invention converts the previously harmful petroleum-derived solvents into beneficial biodegradable synthetic esters. By selecting dibasic esters with specific molecular structures, the patent transforms substances that would otherwise persist in the environment into compounds that degrade naturally, turning an environmental liability into an eco-friendly solution while maintaining functional effectiveness.
2Ease of operation
If conventional carrier solvents are used, then the pheromone composition can be applied, but diffusion stability and efficiency are variable
Solution Approach 1:
The patent optimizes physical parameters of the carrier solvent by selecting dibasic esters with specific vapor pressure ranges (0.1-10 Pa at 20°C) and flash points (≥95°C). These parameter specifications ensure consistent diffusion rates and stable performance across different application conditions, resolving the variability issue while maintaining ease of application.
Solution Approach 2:
The invention incorporates safety feedback mechanisms through the high flash point requirement (≥95°C), which provides inherent thermal safety margins. This feedback parameter ensures that the solvent remains stable under normal operating temperatures and only becomes reactive at significantly elevated temperatures, thereby improving reliability without compromising application capability.
3Productivity
If solvents with high vapor pressure are used for diffusion, then diffusion efficiency increases, but safety risks increase due to lower flash point
Solution Approach 1:
The patent establishes an optimized parameter range for vapor pressure (0.1-10 Pa at 20°C) that balances diffusion efficiency with safety. This parameter window allows sufficient volatility for effective pheromone delivery while maintaining a flash point of at least 95°C, thereby achieving both productivity and safety requirements simultaneously.
Solution Approach 2:
The invention uses composite molecular structures in the dibasic esters, combining specific alkyl chains (R1, R2, R3 groups) to achieve the desired balance between vapor pressure and flash point. The composite structure allows tuning of both diffusion characteristics and thermal safety properties, resolving the contradiction between productivity and safety risks.
