Cageless Lavatory Dispenser Block Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lavatory dispensing devices require cages to support surfactant-containing blocks, which are prone to softening and disintegration, leading to premature failure and increased material costs, and result in wasteful single-use devices.
Innovation Solution
A cageless lavatory device comprising a hanger with a compressed solid block containing titanium dioxide, which is compressed to encase the hanger without the need for a separate cage, allowing long-lasting treatment composition delivery to sanitary appliances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cage is used to support the block composition, then the block is supported and prevented from falling into the toilet bowl, but material costs increase and device complexity increases
Solution Approach 1:
The patent removes the cage component entirely from the device. Instead of using a separate cage to support the block, the invention integrates the support function directly into the block composition itself through the use of an expandable matrix that provides structural integrity without requiring an external cage structure.
Solution Approach 2:
The patent combines the block composition and support structure into a single integrated unit. The expandable matrix serves both as the structural support and as part of the treatment composition delivery system, eliminating the need for a separate cage component.
2Reliability
If a cage is used to support the block composition, then the block is contained and supported, but manufacturing costs increase due to additional molding operations
Solution Approach 1:
The patent eliminates the cage component and its associated molding operations. The support function is achieved through the expandable matrix within the block composition itself, which requires no separate molding process and can be manufactured as a single integrated unit.
Solution Approach 2:
The patent changes the physical and chemical parameters of the block composition to include an expandable matrix that provides structural support. This modification to the composition parameters allows the block to maintain its own structural integrity without requiring a separate cage structure.
3Productivity
If conventional blocks are used, then the device can deliver treatment composition, but the blocks soften and disintegrate prematurely reducing service life
Solution Approach 1:
The patent modifies the physical and chemical parameters of the block composition by incorporating an expandable matrix. This matrix maintains the block's structural integrity and prevents premature softening and disintegration, thereby extending the service life while still allowing effective delivery of the treatment composition.
Solution Approach 2:
The patent uses a composite material structure consisting of the treatment composition integrated with an expandable matrix. This composite structure provides both the therapeutic function and the structural support needed to prevent premature degradation, extending the device's service life.
4Reliability
If a cage is used to support the block, then the block is supported, but the device becomes single-use and wasteful
Solution Approach 1:
The patent removes the cage component that necessitates single-use disposal. By integrating the support function into the block composition itself through the expandable matrix, the device can be reused multiple times without requiring replacement, thereby reducing material waste.
Solution Approach 2:
The expandable matrix within the block composition provides self-supporting capabilities, eliminating the need for an external cage structure. This self-contained design allows the device to maintain its structural integrity over multiple uses without requiring replacement.
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 cageless design extends the service life of the device by preventing premature softening and disintegration, reduces material costs, and allows for multiple uses, while titanium dioxide improves the block's surface appearance and durability.
Implementation Method 1
a compressed solid block comprising one or more chemical constituents but which solid block necessarily includes titanium dioxide for use with a sanitary appliance
Implementation Method 2
titanium dioxide improves the block's surface appearance and durability
Implementation Method 3
The treatment composition is formed by water contacting the block of the device coming into contact with the one or more chemical constituents; the block provides for the long term release of the one or more active agents during sequential contacts with water
