Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling the volatility of non-polar volatile liquid compounds, such as essential oils, are inefficient for prolonged and commercially viable applications, as they quickly vaporize and lose effectiveness.
Innovation Solution
A composite material is developed by mixing non-polar volatile liquid compounds with hydrophobic materials like aggregates, particulates, or fabrics, which reduces volatility and allows for a controlled slow release of vapors, enabling effective and long-lasting applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If non-polar volatile liquid compounds are used in conventional forms, then they provide immediate vaporization and rapid effect, but they quickly lose effectiveness due to rapid vaporization
Solution Approach 1:
The patent employs hydrophobic porous materials (such as porous polymers, activated carbon, or zeolites) as carriers for the non-polar volatile liquid compounds. The porous structure provides large surface area and adsorption sites that control the release rate of the volatile compounds, preventing rapid vaporization while maintaining effectiveness over extended periods. The pore size and surface area can be adjusted to optimize the balance between initial vaporization rate and prolonged duration of action.
Solution Approach 2:
The patent creates composite materials by combining non-polar volatile liquid compounds with hydrophobic porous materials to form a synergistic system. The composite structure integrates the volatility of the liquid compounds with the controlled release properties of the porous carrier, achieving both rapid initial effect and prolonged duration of action. The composite material can be applied in various forms including powders, granules, or coated surfaces.
2Duration of action of moving object
If the volatility of non-polar volatile liquid compounds is reduced to extend duration of action, then effectiveness is prolonged, but the rate of vaporization becomes too slow for immediate effect
Solution Approach 1:
The hydrophobic porous materials provide a controlled release mechanism where volatile compounds are adsorbed onto the pore surfaces and released gradually through diffusion and desorption processes. The pore structure acts as a reservoir that maintains a steady vaporization rate over time, preventing both rapid loss and excessive slowness. The surface area to volume ratio of the porous material can be optimized to control the balance between initial release rate and prolonged duration.
Solution Approach 2:
The patent utilizes changes in physical parameters of the carrier material (such as pore size, surface area, hydrophobicity, and porosity) to control the vaporization rate. By adjusting these parameters, the system can be tuned to achieve the desired balance between rapid initial vaporization and prolonged effective release. The hydrophobicity of the carrier material is specifically optimized to prevent premature vaporization while allowing controlled release over time.
3Duration of action of moving object
If hydrophobic materials are used to control volatility, then slow release is achieved, but the complexity of material preparation increases
Solution Approach 1:
The patent employs commercially available hydrophobic porous materials such as activated carbon, zeolites, and porous polymers that can be obtained through standard industrial processes. These materials require minimal preparation beyond simple mixing and formulation, avoiding complex synthesis steps. The porous materials are used in their natural or lightly processed forms, reducing the overall complexity of material preparation while maintaining effective controlled release functionality.
Solution Approach 2:
The composite material formulation uses straightforward mixing processes to combine non-polar volatile liquid compounds with hydrophobic porous carriers. The preparation method involves simple steps such as dissolving the liquid compound in a volatile carrier, mixing with the porous material, and forming the final composite product. This approach avoids complex chemical synthesis, purification, or specialized processing steps, maintaining commercial viability while achieving the desired controlled release performance.
