Multiphase Cleaning Tablet Segmentation for Safe Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning agents for commercial kitchen appliances often contain highly alkaline, caustic, or toxic components, posing safety risks due to their irritating or corrosive nature, and there is a need for a cleaning tablet that allows safe handling without extensive safety precautions.
Innovation Solution
A multi-phase cleaning tablet with a first cleaning phase containing sodium hydroxide and a second phase with no caustic, toxic, or irritating components, arranged in a layered structure where the second phase covers the first phase on two sides, and optionally coated with a water-soluble protective film to prevent accidental contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If highly alkaline cleaning components (sodium hydroxide) are used to achieve effective cleaning performance, then cleaning effectiveness is improved, but safety hazards increase due to corrosive and irritating properties
Solution Approach 1:
The cleaning tablet is divided into multiple phases: a first phase containing the highly alkaline sodium hydroxide component and a second phase containing no caustic, toxic, or irritating components. This segmentation isolates the hazardous cleaning agent within a specific phase, allowing effective cleaning while minimizing safety hazards through physical separation.
Solution Approach 2:
Different phases of the cleaning tablet have different properties: the first phase is highly alkaline for effective cleaning, while the second phase is safe for contact. This local differentiation of quality allows the tablet to provide both strong cleaning performance in the first phase and safety in the second phase, resolving the contradiction between effectiveness and safety.
2Object-affected harmful factors
If a water-soluble protective film is applied to prevent contact with caustic components, then safety is improved, but the film hardens and becomes brittle after short storage, losing its water-soluble properties
Solution Approach 1:
The protective film is designed as a short-living protective layer that provides safety during storage and handling but is intended to be consumed or removed during the cleaning process. The film's temporary nature is acceptable because it serves its protective function until the tablet is activated, after which the cleaning process itself becomes the primary function.
Solution Approach 2:
The protective film is applied in advance during tablet manufacturing to prevent contact with caustic components during storage and handling. This preliminary protective action ensures safety before the tablet is used, and the film is designed to dissolve or be removed when the cleaning process begins, transitioning from protective function to cleaning function.

AI summary
The invention relates to a multiphase cleaning tablet (1) comprising a first cleaner phase with an alkali system made of one or more components, at least one component of which contains sodium hydroxide (caustic soda), said component not being suitable for touching, and comprising a second cleaner phase for covering the first cleaner phase. The second cleaner phase contains substantially no components which are not suitable for touching, in particular no corrosive, toxic, or hygroscopic components, optionally no irritating components either, and the cleaning tablet is designed as an at least three-layer tablet with a first layer (10) of the second cleaner phase, a second central layer (12) of the first cleaner phase, and a third layer (14) of the second cleaner phase. The invention further relates to a method for producing such a multiphase cleaning tablet (1) and to the use thereof for cleaning kitchen devices, in particular of the commercial kitchen field.
