Foaming Cleaning Composition with Spray Dispenser for Dishware
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual dishwashing under running water often requires excessive detergent, longer mixing times, and increased effort due to the need for scrubbing, especially when dealing with lightly soiled or heavily soiled items, and there is a need for a product that can effectively clean a variety of soils with minimal waste and inhalation risks.
Innovation Solution
A foaming cleaning composition housed in a spray dispenser, containing a surfactant system with a branched short chain alkyl sulfate and a glycol ether solvent in a specific weight ratio, which generates long-lasting suds, reduces scrubbing effort, and minimizes overspray, suitable for quick and effective cleaning of dishware under running water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If detergent is delivered to a sponge for cleaning small number of items, then cleaning can be performed, but excessive detergent is dosed requiring more rinsing
Solution Approach 1:
The spray dispenser automatically controls detergent delivery to the sponge, eliminating the need for manual dosing by the user. The system self-regulates the amount of detergent transferred, ensuring optimal quantity is applied without excess, thereby reducing rinsing requirements and detergent waste.
Solution Approach 2:
The manual mechanical action of squeezing detergent from a bottle onto a sponge is replaced with a spray dispenser mechanism that uses pressurized aerosol technology. This substitution enables precise controlled delivery of detergent directly to the sponge or cleaning surface, preventing over-application.
2Ease of operation
If detergent is mixed with water in the sponge, then cleaning solution is prepared, but time is required slowing down the cleaning process
Solution Approach 1:
The detergent and water are pre-mixed in aerosol form within the spray dispenser before application. This preliminary preparation eliminates the need for the user to perform mixing action during the cleaning process, saving time and enabling immediate use upon spraying.
Solution Approach 2:
The cleaning composition is delivered as an aerosol spray that transitions from a pressurized liquid/gas mixture in the dispenser to a fine mist upon release. This phase transition delivers pre-mixed cleaning solution directly to the sponge or surface, eliminating manual mixing time.
3Productivity
If spray composition is applied to dishware, then cleaning is facilitated, but spreading to surrounding atmosphere causes waste and inhalation risks
Solution Approach 1:
The cleaning composition is nested within a pressurized spray dispenser system that contains the aerosol mixture until moment of use. This nested structure controls the release of the composition, directing it precisely where needed while minimizing uncontrolled dispersion into the surrounding atmosphere.
Solution Approach 2:
The spray dispenser acts as an intermediary device between the cleaning composition and the dishware surface. It mediates the delivery by controlling aerosolization and spray pattern, ensuring the composition reaches the target surface efficiently while minimizing atmospheric dispersion and associated hazards.
