Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garbage disposal cleaners face challenges with liquids being easily flushed away and solid tablets experiencing incomplete dissolution and handling issues, while powdered compositions are prone to premature decomposition due to humidity and temperature fluctuations.
Innovation Solution
A water-soluble, encapsulated powdered composition packaged in a film pouch containing bicarbonate, fragrance, and surfactants, which releases carbon dioxide upon contact with water to create a foaming mechanism for effective cleaning and sanitizing, maintaining stability across high humidity and temperature ranges without the need for secondary protective packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid cleaners are used to clean garbage disposals, then cleaning effectiveness is improved, but the liquid is easily flushed away before completing the cleaning action
Solution Approach 1:
The composition utilizes phase transition by generating carbon dioxide gas from the acid-base reaction between encapsulated bicarbonate and acid components. This gas evolution creates effervescence and foam that expands to fill the disposal chamber, transforming the cleaning medium from liquid to gas phase, which maintains contact with surfaces longer and prevents premature flushing
Solution Approach 2:
The invention changes the physical state parameters of the cleaning composition by using encapsulated powdered bicarbonate and acid that react upon contact with water to produce carbon dioxide gas. This parameter change from liquid to gas phase extends the duration of action by creating a foaming action that adheres to surfaces and cannot be easily flushed away
2Ease of operation
If solid tablets are used to clean garbage disposals, then handling convenience is improved, but dissolution is incomplete and slow
Solution Approach 1:
The tablet is segmented into fine powdered particles of encapsulated bicarbonate and acid components. This segmentation increases the total surface area dramatically, allowing rapid dissolution and reaction when water is added, while the effervescent action of gas evolution further accelerates breakdown and dissolution
Solution Approach 2:
The invention uses the pneumatic action of carbon dioxide gas evolution from the acid-base reaction to accelerate the dissolution process. The effervescence creates mechanical agitation and bubble formation that speeds up the dissolution of components, combining chemical reaction with physical agitation
3Productivity
If powdered composition includes mixed alkaline material and acid, then cleaning effectiveness is improved, but premature decomposition occurs due to humidity and temperature
Solution Approach 1:
The harmful interaction between alkaline bicarbonate and acid is extracted by separating them into different encapsulated components. Each component is individually encapsulated in water-soluble film, preventing premature contact and reaction. The encapsulation isolates the reactive components until use, when water triggers simultaneous dissolution and reaction
Solution Approach 2:
Water acts as an intermediary that triggers the cleaning action. The encapsulated bicarbonate and acid remain stable during storage, and only upon contact with water do they dissolve and react. The water-soluble encapsulation material serves as a mediator that controls the timing of the reaction, preventing premature decomposition while enabling effective cleaning
4Productivity
If hygroscopic bicarbonate is used in powdered composition, then cleaning effectiveness is improved, but the composition cakes when exposed to humidity
Solution Approach 1:
The hygroscopic bicarbonate is extracted and encapsulated in water-soluble film, isolating it from environmental humidity during storage. The encapsulation prevents moisture uptake that would cause caking, while still allowing the bicarbonate to function effectively when the encapsulation dissolves in water during use
Solution Approach 2:
The bicarbonate particles are coated with a thin water-soluble film encapsulation that acts as a protective barrier against humidity. This flexible shell prevents caking by blocking moisture access during storage, yet dissolves readily in water to release the active bicarbonate component for cleaning action
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 encapsulated composition remains stable and effective, providing prolonged contact with disposal surfaces for cleaning and sanitizing without premature reaction, eliminating the need for additional packaging and ensuring ready-to-use convenience.
Implementation Method 1
When the acid and bicarbonate come into contact with water in the disposal unit, carbon dioxide gas is released
Implementation Method 2
The carbon dioxide gas acts with the surfactants and the grinding action of the disposal to build a foam and expand and fill the interior portion of the disposal
