Cageless Lavatory Dispenser Hanger Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toilet bowl treatment 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 dispensing device featuring a hanger with a compressed solid block of chemical constituents, including surfactants, that is retained without a separate cage or adhesive, allowing for repeated use and effective delivery of cleaning and sanitizing agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cage is used to support the solid block composition, then the block is prevented from softening and disintegrating, but material costs and device complexity increase
Solution Approach 1:
The invention extracts and removes the cage component from the device, allowing the solid block composition to be supported directly by the hanger without requiring a separate cage structure. This eliminates the complexity and material costs associated with the cage while maintaining the block's structural integrity through direct hanger attachment.
Solution Approach 2:
The invention merges the support function previously performed by the cage with the hanger structure. The hanger is designed to directly hold and support the solid block composition, combining the suspension and support functions into a single component, thereby eliminating the need for a separate cage.

3Reliability
If a cage is used to support the solid block composition, then the block is prevented from softening and disintegrating, but the device becomes single-use and wasteful
Solution Approach 1:
The invention extracts and removes the cage component from the device, allowing the solid block composition to be supported directly by the hanger without requiring a separate cage structure. This eliminates the complexity and material costs associated with the cage while maintaining the block's structural integrity through direct hanger attachment.

The hanger is designed to directly hold and support the solid block composition, combining the suspension and support functions into a single component, thereby eliminating the need for a separate cage.
4Ease of manufacture
If the solid block composition is retained without a cage, then material costs and waste are reduced, but the block is prone to softening and disintegration
Solution Approach 1:
The invention merges the support function previously performed by the cage with the hanger structure. The hanger is designed to directly hold and support the solid block composition, combining the suspension and support functions into a single component, thereby eliminating the need for a separate cage while maintaining structural integrity.
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 device provides a long-term cleaning and sanitizing benefit without the need for cages, reducing material costs and waste, and maintaining the surfactant's effectiveness over multiple flushes and immersions.
Implementation Method 1
the treatment composition is formed by water contacting the block of the device coming into contact with the one or more chemical constituents
Implementation Method 2
the solid block composition and/or gel composition typically comprises one or more cleaning constituents, e.g., one or more surfactants which provide a good cleaning and/or foaming benefit

AI summary
The present invention relates to a cageless lavatory dispensing device comprising a hanger (10) and a compressed solid block. The hanger (10) has a hook end (20) for suspending the dispensing device to a sanitary appliance, and the compressed solid block (50) comprises at least one chemical agent. A process for delivering a treatment composition to a sanitary appliance is also disclosed. Said process comprises the steps of: providing and suspending a cageless lavatory dispensing device within the sanitary appliance; periodically flushing water about the exterior of the compressed block to elute at least one chemical constituent to form a treatment composition with said water, which treatment composition provides cleaning and/or sanitizing and/or disinfecting benefit to the sanitary appliance.
