Pre-moistened Wipe with Adsorbent Particles for Odor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pre-moistened wiping products do not effectively capture and reduce malodors generated from surfaces being cleaned, particularly in applications like diaper changes and cleaning hard surfaces, where odor control is necessary in addition to cleaning functionality.
Innovation Solution
A pre-moistened wipe with a sheet-like substrate containing a wiping solution that includes odor control agents such as inorganic oxide particles modified with transition metals, quinone compounds, or activated carbon, which are designed to absorb and neutralize malodors, and are applied to both the surface being cleaned and adjacent surfaces to reduce odor emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-moistened wipes are used for cleaning surfaces, then cleaning effectiveness is improved, but odor control capability is insufficient
Solution Approach 1:
The patent combines cleaning functionality and odor control functionality into a single pre-moistened wipe product. The wiping solution contains both surfactants for cleaning and odor control agents (such as activated carbon, zeolite, or other adsorbent particles) that work simultaneously to remove dirt and capture malodors during the same wiping action, eliminating the need for separate odor control steps.
Solution Approach 2:
The wiping solution is formulated as a composite system containing multiple functional components: surfactants for cleaning, odor control agents (adsorbent particles like activated carbon or zeolite), and optionally fragrances. This composite formulation allows the single product to deliver both cleaning and odor control benefits through synergistic interaction of its components.
2Object-generated harmful factors
If odor control agents are added to the wiping solution, then odor control capability is improved, but solution complexity increases
Solution Approach 1:
The patent utilizes porous adsorbent materials such as activated carbon, zeolite, or other porous particles as odor control agents. These materials provide high surface area and porosity that enable effective odor capture through physical adsorption. The porous structure allows odor molecules to be trapped within the material matrix, providing efficient odor control without requiring complex chemical formulations.
Solution Approach 2:
The odor control agents act as intermediary substances that mediate between the malodorous environment and the user. These adsorbent particles capture and hold odor molecules, preventing them from reaching the user's senses. The intermediary nature of these materials simplifies the overall system by providing a straightforward adsorption mechanism rather than requiring complex odor neutralization chemistry.
3Object-generated harmful factors
If the wipe is designed to control odors on adjacent surfaces, then odor control scope is improved, but application requirements increase
Solution Approach 1:
The pre-moistened wipe is designed with universal functionality to perform multiple tasks: cleaning the primary surface, controlling odors on that same surface, and transferring odor control capability to adjacent surfaces. The wipe can be used during diaper changes to clean the baby, control odors on the baby's skin, and when disposed of in the diaper, continue to control odors as the diaper decomposes. This multi-functionality is achieved through the durable odor control agents that remain active on surfaces after the wipe is removed.
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 effectively reduces malodors on the wipe and adjacent surfaces, providing odor control during and after use, including in wet environments, and can be used in various applications such as baby care and surface cleaning, maintaining a clean and odor-free environment.
Implementation Method 1
