Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toilet cleaners, in the form of liquids, powders, tablets, or adhered supports, have limitations such as rapid dissolution, hazardous chemicals, inhalation risks, and limited cleaning efficacy, necessitating a safer and more effective solid cleaner.
Innovation Solution
A solid granular toilet cleaner comprising 50-80% cleaning agent, 10-30% effervescent agent, and optional additives like foaming and lubricating agents, manufactured via extrusion, providing high cleaning power and user perception of cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid cleaners are used, then ease of application is improved, but dissolution speed increases too rapidly causing waste
Solution Approach 1:
The patent changes the physical state parameter from liquid to solid granular form, and controls dissolution speed through granule size and composition parameters. This allows the cleaner to be applied easily like liquids but dissolves at a controlled, slower rate providing sustained cleaning action.
Solution Approach 2:
The patent uses composite granular material combining cleaning agents with granular carriers (such as polymeric beads or porous particles). This composite structure provides both ease of handling/application and controlled dissolution characteristics, resolving the contradiction between easy application and rapid dissolution.
2Quantity of substance
If powder cleaners are used, then cleaning coverage is improved, but inhalation risk increases
Solution Approach 1:
The patent encapsulates cleaning agents within granular particles that have a defined outer structure. This granular shell form prevents the cleaning powder from becoming airborne like traditional powders, eliminating inhalation risks while maintaining adequate cleaning coverage through controlled release.
Solution Approach 2:
The cleaning agent is localized within granular particles rather than dispersed as free powder. This local containment within the granule structure allows the cleaner to provide coverage while preventing the harmful inhalation effect associated with loose powders.
3Power
If high concentration of cleaning agent is used, then cleaning power is improved, but safety decreases due to corrosive chemicals
Solution Approach 1:
The patent uses granular carriers or matrices as intermediaries that contain and control the release of cleaning agents. This intermediary structure allows high concentrations of cleaning agents to be incorporated while controlling their release rate and reducing direct contact with surfaces, thereby maintaining cleaning power while improving safety.
Solution Approach 2:
The patent changes the delivery parameter from direct application of concentrated liquid/corrosive chemicals to controlled release from granular matrices. This parameter change allows high cleaning agent concentration to be used safely, as the granular form controls exposure and reduces corrosive effects.
4Duration of action of moving object
If tablets are used, then cleaning duration is improved, but dissolution control is lost leading to premature dissolution
Solution Approach 1:
The patent creates granules with non-uniform local properties, including varied pore sizes, density gradients, and compositional heterogeneity within each granule. This local quality variation ensures that different parts of the granule dissolve at different rates, providing controlled, sustained release over an extended period rather than premature complete dissolution.
Solution Approach 2:
The patent uses composite granular materials with multiple components having different dissolution rates. This composite structure provides both extended cleaning duration and controlled dissolution, as the various components release at different rates, preventing premature complete dissolution while maintaining long-lasting cleaning action.
