Latent Wetting Device Integration for Dry-to-Wet Paper Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dry toilet paper and dry paper towels do not provide adequate hygienic cleaning, leading to health issues and difficulties in promoting their use due to the need for moisture to effectively clean and disinfect surfaces, with existing solutions like wet wipes being expensive and inconvenient.
Innovation Solution
Integration of a latent wetting device between sheets of dry paper products, allowing users to activate moisture with one hand using capillary action, combined with anti-microbial agents for enhanced cleaning and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If dry toilet paper is used alone, then it is inexpensive and convenient to use, but it does not provide adequate hygienic cleaning and leaves residue and stain on the body
Solution Approach 1:
The patent combines dry toilet paper with a latent wetting device into a single integrated product. The wetting device contains liquid cleaning agent that is activated by hand pressure, allowing the paper to transition from dry to wet state during use. This merging resolves the contradiction by providing both the convenience of dry paper and the hygienic effectiveness of wet cleaning in one product.
Solution Approach 2:
The liquid cleaning agent is pre-loaded into the latent wetting device during manufacturing, ready for activation. The device is prepared in advance with the cleaning solution sealed until the user applies hand pressure to release it. This preliminary preparation allows the product to deliver effective hygienic cleaning without requiring separate wet wipes or preparation steps.
2Reliability
If wet wipes are used in combination with dry toilet paper, then adequate hygienic cleaning is provided, but the cost increases and two different products are required
Solution Approach 1:
The patent merges the functions of dry toilet paper and wet wipes into a single integrated product. The latent wetting device is embedded within the dry paper roll, allowing users to access both dry and wet cleaning capabilities from one product rather than managing two separate products. This reduces device complexity while maintaining hygienic effectiveness.
Solution Approach 2:
The integrated product performs multiple functions: it provides dry blotting capability and wet cleaning capability within a single product system. The latent wetting device enables the paper to function as either dry tissue or wet wipe depending on user activation, making the product universal for both dry and wet cleaning needs.
3Reliability
If wet wipes are used, then moisture is provided for cleaning, but they are expensive and require separate storage
Solution Approach 1:
The latent wetting device is nested within the structure of the dry toilet paper roll. The liquid cleaning agent is contained in a compact reservoir that fits inside the paper layers, allowing the wetting function to be integrated without significantly increasing the overall size or storage requirements of the product. This nested configuration maintains ease of manufacture and storage while providing moisture for cleaning.
4Reliability
If a latent wetting device is integrated into dry paper products, then effective hygienic cleaning is provided with one product, but the manufacturing complexity increases
Solution Approach 1:
The latent wetting device is pre-assembled and pre-filled with liquid cleaning agent during the manufacturing process, before integration with the dry paper product. This preliminary preparation allows for standardized manufacturing steps that, while adding complexity, enable automated production and consistent quality control, making the integrated product manufacturable at scale.
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
Provides effective and convenient hygienic cleaning without the need for separate wet wipes, reducing health risks and costs by allowing dry paper products to be used wet or dry as needed, while maintaining existing product forms and dispensing methods.
Implementation Method 1
allowing the consumer to have a dry towel, or to press or squeeze the sheet with one hand to produce a wetted towel

AI summary
Dry, plied roll paper is transformed into hand wetted roll paper that may be used either dry, or selectively hand wetted using a wetting device. The device is then shaped into a container filled with an anti-bacterial cleaning agent, or other agent, and assembled on the paper ply. The hand wetted paper ply can be used as paper towels or toilet paper for dry and/or wet hygienic cleaning.
