Parallel Wet Wipe Folding and Rolling for Space and Moisture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing processes for individually wrapped wet wipes are inefficient, particularly in terms of speed and space utilization, and often result in loss of cleansing fluid during the folding and rolling processes.
Innovation Solution
A method and apparatus that involves folding and rolling wipes in parallel lanes, using a rolling mechanism with retractable containment sleeves, eliminating the need for a phasing conveyor, and optimizing the folding and rolling steps to minimize space and improve efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional sequential processing methods are used for individually wrapped wet wipes, then manufacturing speed may be maintained, but space requirements increase and fluid loss occurs during transfer between modules
Solution Approach 1:
The patent combines multiple processing functions (folding, rolling, and packaging) into a single integrated apparatus that operates in parallel lanes. This merging eliminates the need for separate traversing modules and phasing conveyors, reducing the overall space footprint while maintaining high manufacturing throughput through concurrent processing of multiple wipes simultaneously
Solution Approach 2:
The invention transitions from sequential single-lane processing to parallel multi-lane processing, effectively adding a dimensional aspect to the manufacturing process. By arranging multiple processing lanes side-by-side within a compact footprint, the system achieves higher productivity without proportionally increasing the apparatus space
2Ease of manufacture
If traditional folding and rolling processes are used, then wipe preparation can be completed, but cleansing fluid is lost during the process
Solution Approach 1:
The patent performs folding operations before the wiping surface is exposed, and implements fluid retention measures throughout the closed-package process. By preparing the wipe structure in advance while it remains enclosed and moistened, the system achieves proper wipe formation without exposing the cleansing fluid to loss during handling and processing
Solution Approach 2:
The invention uses a flexible, form-fitting package that conforms to the rolled wipe and maintains a sealed environment. This flexible packaging structure protects the cleansing fluid from evaporation and leakage during the folding, rolling, and storage processes while allowing the wipe to be properly formed
3Ease of operation
If individually wrapped wipes are produced, then portability and freshness are improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the manufacturing process into parallel lanes that each handle individual wipes independently. This segmentation allows each lane to perform the complete sequence of folding, rolling, and packaging operations simultaneously, creating individually wrapped products through a systematic division of labor that manages complexity through parallelization rather than sequential complexity
