Portable multi-component fluid and paper based product dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dispensers for flowable and paper-based products, such as sanitizer and hand wipe dispensers, expose multiple wipes to contaminants due to interconnected designs, which compromises the sanitation and shelf life of the products.
Innovation Solution
A dual compartment dispenser with an airless pump and a cylindrical container for interfolded paper-based products, featuring a minimized aperture and a tight-fitting lid to ensure each wipe is dispensed individually, preventing exposure to air and contaminants, and utilizing a diaphragm mechanism and spring nozzle for efficient fluid dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If interconnected wipes are dispensed through a common aperture, then multiple wipes can be accessed simultaneously, but multiple wipes are exposed to contaminants in the air
Solution Approach 1:
The dispenser is divided into separate compartments: one for wipes and one for sanitizer. Each compartment has its own controlled aperture, preventing cross-contamination between products and eliminating exposure of multiple wipes to air contaminants through a shared opening.
Solution Approach 2:
A barrier membrane or sealed aperture design acts as an intermediary between the stored wipes and the external environment. This intermediary allows controlled access to individual wipes while maintaining a sealed environment that prevents contaminant exposure.
2Ease of operation
If a large aperture is provided for wipe dispensing, then wipes can be easily accessed, but the aperture exposes more wipes to air and contaminants
Solution Approach 1:
The aperture is designed with localized functionality - it is positioned and sized specifically to expose only the single wipe needed for dispensing. The surrounding areas remain sealed, maintaining different quality zones: an open local area for wipe access and sealed areas for contamination protection.
3Ease of operation
If wipes are stored in an open container, then they are easily accessible, but they are exposed to contaminants and microbials
Solution Approach 1:
The harmful element (air exposure) is extracted from the wipe storage environment. The wipes are kept in a sealed container that is only opened momentarily for dispensing, removing the continuous exposure to contaminants while maintaining easy access during the dispensing action.
4Reliability
If a dual compartment design is used to separate wipes and sanitizer, then product contamination is prevented, but device complexity increases
Solution Approach 1:
Two separate functional compartments (wipe storage and sanitizer storage) are merged into a single integrated dispenser unit with a unified housing and coordinated dispensing mechanisms. This combining approach maintains product protection while avoiding the complexity of two separate devices.
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 ensures each disposable wipe is sanitary and protected from contaminants, maintaining product quality and extending shelf life, while the airless pump mechanism ensures consistent and controlled dispensing of the aqueous substance.
Implementation Method 1
The first compartment having an air pump dispenser through which fluid is being dimensioned to house an aqueous substance that is moved upward via a base plate

AI summary
A portable multicomponent fluid and paper based product dispenser having an airless pump dispensing unit mounted to a container body having an outlet through which disposable goods may be successively drawn. The airless pump housing unit contains a diaphragm mechanism and spring nozzle positioned in the center of the apparatus superiorly and a disk shaped base plate positioned in the bottom inner circumference of the shell, separated by aqueous solvent. Air intake received from the bottom portion of the outer shells of both the upper and lower compartment structures, causes an upward flow of product via a vacuum chamber. A wall which creates division between the upper and lower compartments and the remainder of the outer shell houses the enclosed interfolded sediment free disposable wipes that are removed through an outlet. The outlet is closeable by means of a detachable cap.
