Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antibacterial and antiviral surface treatments, such as paints, face limitations including reduced active ingredient performance over time, difficulty in suspension and application, limited flexibility and durability, potential for organic growth, odor and allergenic issues, and challenges in adapting to emerging pathogens, as well as requiring specialized skills and tools for application.
Innovation Solution
A multilayer flexible material with a tie binding layer and an active treatment layer comprising antibacterial and antiviral agents, allowing for easy application and perpetual self-sanitizing properties, featuring a pressure-sensitive adhesive and various forms of active materials like copper and silver, which can be applied directly to surfaces or used as wound dressings, and can be combined with other surfaces for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paints or coatings are used for antibacterial and antiviral treatment, then the surface can be treated, but the active ingredients performance reduces with time due to binder coverage
Solution Approach 1:
The treatment is divided into separate functional layers: a binder-free active ingredient layer and a separate adhesive layer. This segmentation prevents the active ingredients from being covered and deactivated by binders, while still providing secure attachment to the substrate.
Solution Approach 2:
The active ingredient layer is extracted from the binder matrix that typically encapsulates antimicrobial agents in paints. By removing the binder component from direct contact with the active ingredients, their performance and longevity are preserved.
2Ease of operation
If liquid form antibacterial and antiviral ingredients are used in paints, then they can be applied, but they are difficult to put into suspension and apply
Solution Approach 1:
The active ingredients are changed from liquid form to solid forms (powders, flakes, granules, or foils). This parameter change eliminates suspension difficulties while maintaining applicability through the adhesive layer system.
3Adaptability or versatility
If binders and other paint components are used, then the paint can be applied, but they limit the elimination of a broad range of antibacterial and antiviral materials
Solution Approach 1:
By separating the active ingredient layer from the binder system, the invention enables the use of diverse antibacterial and antiviral materials (copper, silver, zinc, titanium dioxide, etc.) without compatibility constraints imposed by binder chemistry.
4Ease of operation
If paints are used for surface treatment, then the surface can be treated, but application is time consuming and requires specialized skills and tools
Solution Approach 1:
The treatment can be applied as a disposable sticker or tape that is pre-loaded with active ingredients. This eliminates the need for skilled application and allows immediate use without curing time, as the entire treatment layer is applied in one piece.
5Reliability
If organic paints are used, then the surface can be treated, but they themselves become breeding ground for organic growth
Solution Approach 1:
The organic binder component that creates a breeding ground for microbial growth is extracted from the system. The active ingredients are applied in a binder-free manner, eliminating the organic substrate that would otherwise support unwanted organic growth while maintaining the desired antimicrobial function.
6Adaptability or versatility
If paint film is applied, then the surface can be treated, but the film thickness is limited and can be applied only on limited selected type of surfaces
Solution Approach 1:
The adhesive layer is designed to be universally applicable to various surface types (smooth, porous, curved, irregular). This multi-functional adhesive system allows the same active ingredient layer to be effectively applied across diverse substrates without thickness limitations.
