Oxazoline Polymer Touch Screen Cleaning and Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning products for touch screens and screen protectors are inadequate as they either fail to provide long-lasting protection, reduce transparency, have short lifecycles, and are difficult to remove, leading to frequent re-contamination.
Innovation Solution
A cleaning and protectant composition comprising a carrier and a polymeric film former, specifically an oxazoline homopolymer or modified polymer, which forms a retention coating to retain components and provide extended protection against microbes, while maintaining transparency and ease of removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alcohol-based liquid products are used to clean touch screens, then cleaning effectiveness is improved, but protection duration deteriorates (no protection film left)
Solution Approach 1:
The patent combines cleaning function and protection function into a single composition. The alcohol-based liquid cleans the screen while the polymeric film former simultaneously forms a protective coating, merging two separate functions (cleaning and protecting) that were previously performed by different products.
Solution Approach 2:
The composition uses a composite formulation combining alcohol-based cleaning agents with polymeric film formers (oxazoline homopolymer or modified polymer). This composite material provides both the cleaning action of alcohol and the protective film-forming capability of the polymer, resolving the contradiction between cleaning effectiveness and protection duration.
2Duration of action of moving object
If polymer and water-based products are used, then protection duration is improved, but transparency deteriorates
Solution Approach 1:
The patent specifies using oxazoline homopolymer or modified polymer based on oxazoline homopolymer as the film former, which forms a transparent coating. The polymer structure and composition parameters are optimized to ensure the protective film remains transparent while providing extended protection duration.
3Duration of action of moving object
If polymer and water-based products are used, then protection duration is improved, but product build-up occurs affecting transparency
Solution Approach 1:
The patent uses oxazoline homopolymer or modified polymer with specific molecular structure and properties that prevent excessive build-up. The polymer parameters are controlled to form a thin, uniform protective layer that does not accumulate harmful deposits on the screen surface.
4Duration of action of moving object
If polymer and water-based products are used, then protection duration is improved, but removal difficulty increases
Solution Approach 1:
The patent specifies using oxazoline homopolymer or modified polymer that forms a protective film with optimized adhesion and removal properties. The polymer parameters are controlled to provide sufficient protection duration while maintaining ease of removal when needed, balancing durability with removability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively cleans and protects touch screens by forming a durable, transparent film that prevents re-contamination, maintains clarity, and is easily removable, ensuring continuous sanitization and aesthetic appeal for an extended period.
Implementation Method 1
a polymeric film former, wherein the polymeric film former is an oxazoline homopolymer or an extended or a modified polymer based on an oxazoline homopolymer
