Nested Wipe Dispenser Housing for Moisture Retention

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional toilet paper is inadequate for cleaning hands after bowel movements, as it does not disinfect and can be abrasive, and existing dispensers are not suitable for moistened wipes, leading to evaporation and lack of portability.

Innovation Solution

A storage and dispensing system with a linear core element and two housings, one with a lid for access and the other with guiding apertures for the core ends, ensuring the wipes remain moist and allowing for easy retrieval and attachment to a surface, featuring a cutting element and glow-in-dark material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional dispensers are used for moistened wipes, then the wipes can be dispensed, but the liquid evaporates from the moist roll due to lack of airtight sealing

Engineering Contradiction:

Improvemoisture retentionVSAvoiddispenser structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a nested structure where the first housing containing the moistened wipes is placed inside the second housing. The first housing acts as an inner container that can be inserted into and removed from the outer second housing, creating a nested arrangement that provides both airtight sealing for moisture retention and structural support for portability.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent employs flexible sealing mechanisms including gaskets and lids that can conform to the housing structure to create airtight seals. The lid of the first housing and the door of the second housing incorporate sealing elements that flex to maintain contact and prevent liquid evaporation while allowing for assembly and disassembly.

Inventive Principle:

Principle #30Flexible shells and thin films

2Adaptability or versatility

If conventional dispensers are used, then storage is provided, but they lack portability and static positioning capability

Engineering Contradiction:

ImproveportabilityVSAvoidinstallation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The second housing is designed with multiple functions: it provides structural support for the first housing, offers mounting capability through attaching arrangements for wall or surface installation, and enables portability when not mounted. The integrating member allows the two housings to be connected or separated, providing versatility in deployment options.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces an integrating member as an intermediary component that connects the first housing to the second housing. This mediator element facilitates the attachment and detachment of the housings, enabling both permanent installation and portable use without requiring complex integration mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If toilet paper is used for hand cleaning, then it is readily available, but it is abrasive to the rectum and does not disinfect

Engineering Contradiction:

ImproveavailabilityVSAvoidirritation and contamination

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent changes the physical and chemical parameters of the cleaning material by using pre-moistened wipes instead of dry toilet paper. The wipes are saturated with liquid that provides softening and disinfecting properties, transforming the material from abrasive and non-disinfecting to gentle and sanitizing while maintaining ease of use.

Inventive Principle:

Principle #35Parameter changes

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

AI summary

A storage and dispensing arrangement is provided to maintain moistened wipes wet. The moistened wipes are rolled around a core tube and placed inside a first housing. The first housing is then placed inside a second housing having a closing door to isolate the first housing from external environment. The unit is then hanged into a stand, a rack or a wall.
