Disposable Item Protector With Vapor-Permeable Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintaining contaminant-free environments for personal items like toothbrushes is challenging due to the presence of harmful microorganisms, especially in humid and unsanitary areas, where conventional disinfection methods are either ineffective or costly.
Innovation Solution
A disposable item protector with permeable vapor and impermeable microbial and liquid properties, formed by bonding layers with adhesive or cohesive methods, creating a pouch that encloses items and prevents contamination, optionally incorporating antimicrobial agents for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional disinfection methods (chemical treatments, boiling, autoclaving, microwaving) are used on personal items, then microbial contamination is reduced, but the items become unusable or the process is expensive
Solution Approach 1:
The patent applies preliminary action by providing a pre-formed protective barrier (the pouch) that prevents microbial contamination before it occurs, rather than attempting to disinfect items after contamination has happened. The pouch is designed with microbial-blocking properties and is ready to use before any contamination risk arises, eliminating the need for subsequent expensive or damaging disinfection processes.
Solution Approach 2:
The patent employs disposable pouches that are inexpensive to produce and use. These single-use barriers are discarded after one use, avoiding the need for repeated expensive disinfection processes that can damage items. The low cost of the disposable pouch makes it economically viable to use for every item, ensuring consistent protection without compromising item usability.
2Use of energy by moving object
If permeable materials are used to allow items to dry, then vapor transmission is improved, but liquid penetration and microbial contamination risk increase
Solution Approach 1:
The patent utilizes composite materials that combine multiple functional properties in a single structure. The pouch material is engineered to simultaneously provide vapor permeability (allowing drying) and liquid impermeability (blocking contamination). This composite structure resolves the contradiction by integrating both required functions into one material system rather than requiring separate layers or mechanisms.
Solution Approach 2:
The patent employs porous materials with controlled pore structures that allow vapor molecules to pass through while blocking larger liquid droplets and microbial entities. The pore size is specifically designed to be permeable to water vapor for drying purposes but impermeable to liquids and microbes, thus resolving the contradiction between drying capability and contamination protection.
3Productivity
If multiple item protectors are formed at once, then productivity is improved, but the complexity of the bonding and cutting process increases
Solution Approach 1:
The patent applies segmentation by designing the pouch structure with predetermined cut lines that allow the continuous bonded sheet to be easily divided into individual units. The bonding pattern is designed so that adjacent pouches share common bonded edges, and simple cutting along predetermined lines separates them without requiring complex re-bonding or assembly operations, thus maintaining productivity while reducing process complexity.
