Disposable Soap Dispenser Cartridge With Foaming Pump Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-mounted soap dispensers require frequent refilling, leading to laborious maintenance and aesthetic issues due to soap residue buildup, and suffer from wear-and-tear, necessitating constant maintenance for optimal performance and appearance.
Innovation Solution
A wall-mounted soap dispenser with a reusable mounting bracket and a disposable, recyclable or biodegradable cartridge containing an inverted dispensing pump that uses less soap per hand wash and provides foaming soap, allowing for easy replacement of cartridges to maintain appearance and reduce maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional wall-mounted soap dispensers are used with refillable containers, then the dispenser can be reused and reduce waste, but the dispenser requires frequent maintenance and refilling which is laborious and time-consuming
Solution Approach 1:
The soap dispenser is divided into two segments: a reusable mounting bracket and a disposable cartridge. The cartridge contains the soap reservoir and pump mechanism, and can be easily replaced when empty or soiled, eliminating the need for manual refilling and cleaning of the entire dispenser.
Solution Approach 2:
The cartridge is designed as a disposable component that can be easily replaced. When the cartridge becomes empty or accumulates soap residue, the entire cartridge is discarded and replaced with a new one, eliminating maintenance time and labor.
2Ease of operation
If conventional soap dispensers are used with bag-like bladders, then the dispenser can be refilled, but the external appearance becomes defaced and aesthetically displeasing over time
Solution Approach 1:
The dispenser is segmented into a permanent mounting bracket and a replaceable cartridge. The cartridge can be removed and replaced without affecting the mounting bracket, allowing users to maintain aesthetic appearance by replacing rather than refilling.
Solution Approach 2:
The cartridge is designed as a disposable item that maintains aesthetic appearance. Instead of refilling and risking damage to the external housing, users simply replace the entire cartridge when needed, preserving the dispenser's appearance.
3Reliability
If conventional soap dispensers are used with traditional pumps, then the dispenser can function normally, but the pump suffers from wear-and-tear and becomes improperly functioning over time
Solution Approach 1:
The pump mechanism is integrated into the disposable cartridge rather than being a separate permanent component. When the cartridge is replaced, the pump is replaced with it, eliminating wear-and-tear issues on permanent pump components.
Solution Approach 2:
The pump mechanism is incorporated into the disposable cartridge. Each new cartridge contains a fresh pump that has not undergone wear-and-tear, ensuring reliable functionality without the need for separate pump maintenance or replacement.
4Quantity of substance
If conventional soap dispensers are used with liquid hand soap, then the dispenser can provide adequate coverage, but more soap is required per hand washing session
Solution Approach 1:
The invention changes the physical state of the soap from liquid to foamy. The foaming pump mechanism aerates the soap, creating a voluminous foam that provides adequate coverage with less actual soap material per hand washing session.
Solution Approach 2:
The pump mechanism incorporates air mixing to create foam. By introducing air into the soap stream, the system expands the soap volume and improves distribution efficiency, reducing the amount of soap needed per use.
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 provides a low-maintenance, aesthetically pleasing, and environmentally conscious soap dispenser that reduces soap usage and minimizes wear-and-tear, offering improved operational efficiency and appearance by concealing the mounting bracket behind a disposable cartridge.
Implementation Method 1
the vent gasket being an elastomer such that vacuum pressure within the rigid disposable cartridge causes the vent gasket to deflect apart from the vent and air to be drawn in through the vent into the rigid disposable cartridge to equalize air pressure therein
Implementation Method 2
an inverted dispensing pump received within the neck end of the disposable cartridge and adapted to engage within the collar
Data Source
AI summary
A soap dispenser including a rigid cartridge, an inverted dispensing pump, a collar carrying a lever for actuating the pump, and a venting system for equalizing the air pressure in the rigid cartridge, wherein the rigid cartridge and the collar cooperate to removably attach the soap dispenser to a wall-mounted bracket, and further wherein at least the rigid cartridge is disposable and can be made of a recyclable and/or biodegradable material.
