Non-porous Biodegradable Composite Material for Controlled Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing porous materials for controlled release of active substances are complex, often require sterilization or removal of blowing agents, and result in products that are not adaptable to changing user needs, leading to waste due to overproduction or unexpected changes in target use.
Innovation Solution
A method for producing non-porous, biodegradable composite materials that are water- or lipid-absorbent, involving selection of base materials, mixing with cohesion co-formulants, pulverization, wetting, and shaping to create a network of absorbent wicks, allowing for subsequent loading with active liquid compositions for controlled release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If porous materials are produced using blowing agents, then the material structure becomes porous to enable absorption of active ingredients, but the production process becomes complex and requires additional steps to remove blowing agents
Solution Approach 1:
The patent extracts and removes the blowing agent from the final material composition, using it only as a temporary formative element during production. The blowing agent is completely eliminated from the final product, avoiding contamination while still enabling pore formation during the shaping process.
Solution Approach 2:
The blowing agent is introduced during the shaping process to create the porous structure, and then removed in a subsequent step. This preliminary action of forming the structure before removal allows the material to gain its absorption capacity without retaining the harmful blowing agent.
2Ease of operation
If porous supports are used to incorporate active substances, then the active ingredients can be delivered into the environment, but the material requires sterilization or prior purification to remove undesirable elements
Solution Approach 1:
The patent uses a biodegradable blowing agent that is temporarily present during production and then naturally decomposes. This disposable approach eliminates the need for complex sterilization processes, as the blowing agent is removed through natural degradation rather than requiring industrial sterilization equipment.
Solution Approach 2:
The patent converts the potentially harmful presence of the blowing agent into a beneficial formative element during production. The blowing agent creates the necessary porous structure for controlled release, and its subsequent removal is achieved through natural biodegradation, turning a harmful substance into a useful production aid.
3Reliability
If porous materials are produced for controlled release, then active ingredients are delivered in controlled dose, but the products are not adaptable to changing user needs leading to waste
Solution Approach 1:
The patent creates a dynamic system where the porous structure can be adjusted during production to accommodate different active ingredient formulations. The blowing agent concentration and distribution can be modified to change the release characteristics, allowing the same base material to serve multiple applications with different controlled release requirements.
Solution Approach 2:
The patent develops a universal porous material platform that can be adapted for multiple uses by adjusting the blowing agent formulation and distribution. This multi-functional material can serve different agricultural, environmental, or industrial applications with varying controlled release needs, reducing waste from overproduction of single-use products.
