Polymer Phone Case Infused with Antimicrobial Silver and Fragrance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cell phone cases with scent notification systems require propellants for fragrance dispersal, which are costly and not customizable, and lack antimicrobial properties to reduce bacteria on the surface.
Innovation Solution
A cell phone case made from a polymer material infused with antimicrobial agents like silver and fragrance oils, using injection molding to trap these additives within the polymer, providing non-leaching antimicrobial properties and customizable scents without propellants, and enhanced surface treatments for microbial attraction and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If propellants are used for fragrance dispersal in cell phone cases, then fragrance can be dispersed, but manufacturing cost increases
Solution Approach 1:
The patent removes the propellant component from the fragrance delivery system entirely. Instead of using compressed gas or chemical propellants to disperse fragrance, the system relies on passive diffusion and user interaction (opening the case to reveal the scented insert), thereby eliminating the costly propellant requirement while maintaining fragrance functionality.
Solution Approach 2:
The patent employs a disposable or replaceable scented insert that can be easily replaced by the user. This inexpensive, simple component provides fragrance without requiring expensive propellant systems, and can be replaced when the scent fades, offering a cost-effective alternative to integrated propellant mechanisms.
2Adaptability or versatility
If conventional scent notification systems are used, then fragrance can be dispersed, but the system lacks antimicrobial properties
Solution Approach 1:
The patent combines multiple functional properties into a single integrated solution: the scented insert simultaneously provides fragrance delivery and antimicrobial protection through the incorporation of silver particles. This merging of functions allows the cell phone case to both dispense fragrance and reduce bacterial contamination without requiring separate systems.
Solution Approach 2:
The patent uses composite materials by incorporating silver particles into the scented insert matrix. This composite structure provides both the fragrance-carrying polymer material and the antimicrobial properties of silver, creating a multi-functional component that addresses both scent delivery and bacterial reduction needs.
3Reliability
If antimicrobial agents are added to polymer, then antimicrobial properties are achieved, but additives may leach out
Solution Approach 1:
The patent concentrates the antimicrobial silver particles and fragrance within a localized scented insert rather than distributing them throughout the entire cell phone case polymer. This localized concentration ensures high antimicrobial efficacy where needed (at the surface contacting skin) while minimizing the risk of leaching to the environment, as the additives are contained within the insert structure.
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 solution achieves 99.9% antimicrobial efficacy and customizable fragrance options while minimizing manufacturing costs, ensuring the case remains effective against bacteria and providing an appealing appearance.
Implementation Method 1
the microbial agent entrapped in the polymer has minimal contact with the application. This provides the cell phone case with a non-leaching property of the microbial agent. The antimicrobial additive can attract and kill microbes on a surface of the cell phone case.
Implementation Method 2
Surface texture of the cell phone case can be used to increase attraction and retention of microbes to the cell phone case from the host environment by capillary action. Surface treatments can be applied to the cell phone case for increasing the surface tension thereby aiding in the adhesion of microbes during use of the cell phone cases.
