Medicinal Package Odor Reduction Metallic Oxide Desiccant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medicinal compounds with unpleasant smells pose challenges in patient compliance and double-blind clinical trials due to their odor, and existing methods for reducing smells, such as decomposition, absorption, and masking, are insufficient, especially under changing environmental conditions.
Innovation Solution
A medicinal package incorporating a chemical absorption-type desiccant, specifically a metallic oxide like calcium oxide, is used to effectively reduce odors by absorbing moisture and odorous materials, maintaining equilibrium and preventing desorption during transportation and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If synthetic zeolite, silica gel, silica-alumina, or active carbon is used as a desiccant to absorb moisture and odorous materials, then the initial smell reduction is effective, but under changing environmental conditions (temperature, humidity), the absorbed odorous materials can be desorbed, making the smell reduction insufficient
Solution Approach 1:
The patent changes the fundamental parameter of the desiccant from physical absorption (reversible) to chemical absorption (irreversible). By using metallic oxides that chemically react with odorous materials through oxidation or other chemical reactions, the system transforms the temporary physical binding into permanent chemical bonding, eliminating desorption issues under varying environmental conditions
Solution Approach 2:
The patent converts the harmful reversible nature of physical absorption into a beneficial irreversible chemical reaction. The very property that caused the problem (reversibility of absorption) is replaced by its opposite (irreversibility of chemical reaction), turning the weakness of physical absorption into the strength of chemical absorption
2Ease of manufacture
If physical absorption methods are used to remove odorous materials, then the process is simple and the desiccant can be easily replaced, but the absorption capacity decreases under high temperature and humidity conditions
Solution Approach 1:
The patent changes the absorption mechanism from physical to chemical, fundamentally altering how the desiccant interacts with odorous materials. This parameter change enables the system to maintain high absorption capacity across a wide range of temperatures and humidity levels, as chemical reactions are less sensitive to environmental conditions compared to physical absorption equilibrium
