Rounded Wet Wipe Dispenser Lid to Reduce Recontamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reusable dispenser containers for wet wipes are prone to contamination, leading to microbiological issues and reduced cleaning efficacy due to their design, which makes them difficult to clean and maintain, especially in areas that are hard to reach.
Innovation Solution
A dispenser container with a round cross-section and a multi-part lid featuring a handle lid with a central opening and a removal lid, both connected via threads, with rounded edges and corners to prevent contamination, and a disposable removal inlay to minimize contact with reusable components, ensuring easy cleaning and reduced recontamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional multi-part lid system with hinges is used, then the container can be closed and reused, but the lid is susceptible to contamination and difficult to clean due to its shape and hard-to-reach areas
Solution Approach 1:
The patent applies curvature by designing the container with a round cross-section and rounded edges throughout, eliminating acute angles, right angles, and obtuse angles. This spherical/curved geometry prevents contamination accumulation in corners and edges, making the container easier to clean while maintaining reusability.
Solution Approach 2:
The lid is divided into multiple separable parts: a handle lid with handle elements, a removal lid with a removal opening, and a removable inlay. This segmentation allows each component to be easily removed and cleaned separately, eliminating hard-to-reach areas while preserving the reusable container system.
2Device complexity
If a conventional lid design with angles and corners is used, then the structure is simple, but biofilm can form in hard-to-reach areas leading to recontamination
Solution Approach 1:
The patent replaces all angular features with curved surfaces. The container has a round cross-section, and all edges are rounded, eliminating corners where biofilm could accumulate. This curved geometry maintains structural simplicity while significantly improving hygiene by preventing recontamination.
3Adaptability or versatility
If the dispenser container is designed as reusable, then it can be used multiple times, but it requires time-consuming cleaning and disinfection before each refill
Solution Approach 1:
The rounded edges and curved surfaces eliminate corners and crevices that require meticulous cleaning. This allows the reusable container to be quickly and easily cleaned and disinfected before each refill, significantly reducing the time investment required while maintaining reusability.
Solution Approach 2:
The separable lid components can be easily removed and cleaned separately from the main container body. This segmentation simplifies the cleaning process, making it faster and more efficient while preserving the reusable nature of the entire system.
4Device complexity
If a removal opening with sharp edges is used, then the structure is simple, but it can cause injury and is difficult to clean
Solution Approach 1:
The removal opening is designed with rounded edges instead of sharp corners. This curved geometry eliminates injury risks while maintaining structural simplicity, and the rounded edges make the opening easier to clean by eliminating corners where contamination could accumulate.
