Antimicrobial Edge Strip Composition for Deposit-Resistant Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edge strips for the furniture industry face challenges in reducing the deposition of aggressive substances and microorganisms on their surface, while maintaining material and decorative properties, and are often costly to produce.
Innovation Solution
Incorporating oligodynamically acting materials, such as bactericidal and fungicidal metal components or organometallic compounds, in amounts of 0.05 to 20% by total mass, within the polymeric material or decorative elements of the edge strip, ensuring a spatially consistent distribution to prevent chemical or biological incrustations, with metal-releasing substances like zeolites providing long-term protection against microbial growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional complex protective layers are applied to edge strips to prevent microbial growth and deposition of aggressive substances, then the protective effect is improved, but the device complexity and production cost increase
Solution Approach 1:
The patent changes the chemical composition parameter of the polymeric material by incorporating oligodynamically active metals (silver, zinc, copper, or their compounds) at concentrations of 0.01-10% by weight. This parameter change赋予s the base material inherent antimicrobial properties without requiring additional protective layers, thus resolving the contradiction between protective effect and structural complexity
Solution Approach 2:
The patent creates a composite material by combining polymeric material with oligodynamically active metal components. This composite structure integrates the protective function directly into the material matrix, eliminating the need for separate protective layers while maintaining structural integrity and aesthetic appearance
2Object-affected harmful factors
If oligodynamically acting materials are incorporated into the edge strip to prevent deposition of aggressive substances, then the resistance to harmful factors is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent merges the antimicrobial function with the base polymeric material by incorporating oligodynamically active metals during the extrusion or molding process. This integration allows the material to be manufactured in a single step without requiring subsequent coating or treatment operations, thus maintaining ease of manufacture while providing protection against harmful factors
Solution Approach 2:
The antimicrobial protection is built into the material during its initial formation through extrusion or molding, before the edge strip is installed or used. This preliminary incorporation of oligodynamically active materials ensures protection is present from the outset without requiring additional manufacturing steps later
3Reliability
If metal-releasing substances are added to provide bactericidal and fungicidal effects, then the reliability against microorganisms is improved, but the material composition becomes more complex
Solution Approach 1:
The patent optimizes the concentration parameter of metal components to 0.01-10% by weight, which is sufficient to provide reliable bactericidal and fungicidal effects while maintaining the fundamental polymeric nature of the material. This parameter optimization ensures the material retains its basic characteristics while gaining antimicrobial properties
Solution Approach 2:
The oligodynamically active metals are distributed throughout the polymeric matrix to provide localized antimicrobial action at the surface where contact with microorganisms occurs. This local concentration of active ingredients provides effective protection while keeping the overall material composition relatively simple and maintaining bulk material properties

Function Achieved in This Case
The edge strip effectively inhibits the growth of bacteria and fungi, reducing cleaning costs and ensuring long-term protection against deposits in applications like kitchens and medical areas, while being cost-effective and retaining processing benefits.
Implementation Method 1
the material of the profile strip and / or the decorative element contains at least one oligodynamically acting material in an amount of 0.05 to 20% based on the total mass
Implementation Method 2
the metal component is a substance that releases metal ions, which releases the metal ions through contact with, for example, a liquid, in particular when the profile strip is washed
Implementation Method 3
some of the metals contained in the zeolite are replaced by at least one type of ion-exchangeable metals
Implementation Method 4
the substance releasing metal ions is a salt, oxide, carbide, an organometallic and/or inorganic metal compound selected from the group of silver, gold, copper, zinc, lead, arsenic, cadmium
