Foaming Cleaning Formulation Dispensing System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bathroom cleaning formulations struggle to foam when dispensed through non-aerosol devices like FLAIROSOL, leading to inefficient cleaning due to lack of foam stability and inconsistent surface coverage, which results in user fatigue and reduced cleaning efficacy.
Innovation Solution
A foaming cleaning formulation comprising a first nonionic surfactant, a second nonionic surfactant, and a C8 quaternary amine cationic surfactant, combined with a dispensing device featuring a trigger with a specific spring force and orifice size, which together enable the formulation to foam consistently and maintain an extended spray time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a mesh foaming trigger with mesh screen is used to cause foaming during dispensing, then foaming is achieved, but the device becomes complex and requires specialized features that are not compatible with standard dispensers
Solution Approach 1:
The invention changes the chemical parameters of the cleaning formulation by incorporating specific surfactant combinations (nonionic and cationic surfactants) that enable foaming without requiring a mesh screen. This allows standard dispensers to produce foam naturally through the formulation's properties rather than requiring specialized mechanical foaming components.
2Stability of the object's composition
If aerosol dispensers are used to produce foam, then foam is generated, but propellants are used which are environmentally harmful and cause inconsistent dispensing
Solution Approach 1:
The invention replaces the mechanical propellant-based aerosol system with a non-pressurized dispensing mechanism. The foam generation is achieved through the chemical formulation's surfactant properties rather than through pressurized gas propellants, eliminating environmental harm while maintaining foam consistency throughout the product life cycle.
Solution Approach 2:
The invention changes the physical state and chemical composition parameters of the formulation to enable foam generation without propellants. By adjusting surfactant concentrations and types, the formulation maintains consistent foaming properties throughout dispensing without requiring pressurized propellant systems.
3Productivity
If standard trigger sprayers are used, then multiple cleanings are enabled, but trigger fatigue occurs and surface coverage is inconsistent
Solution Approach 1:
The invention changes the formulation parameters to create a foam that adheres properly to vertical surfaces and provides consistent surface coverage. The foam's physical properties (stability, adhesion, drainage rate) are optimized through surfactant selection, allowing users to cover larger areas more effectively without experiencing trigger fatigue from repeated actuations.
