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 waste, and lack efficient cleaning and sanitizing benefits.
Innovation Solution
A cageless lavatory dispensing device featuring a hanger with a compressed solid block composition, angled to remain in the flush water path, eliminating the need for cages and providing sustained cleaning and sanitizing benefits through repeated flushes without adhesive materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a cage is used to support the compressed solid block, then the block's structural integrity is maintained, but material costs and device complexity increase
Solution Approach 1:
The invention removes the cage component entirely from the device structure. The compressed solid block is designed to function independently without requiring a cage for support, thereby simplifying the device structure while maintaining block integrity through optimized compression and material formulation.
Solution Approach 2:
The compressed solid block is engineered to support itself through its own compressed structure and material properties. The block maintains its structural integrity and positioning within the toilet bowl through self-supporting mechanisms rather than requiring an external cage structure.
2Reliability
If a cage is used to support the compressed solid block, then the block remains positioned during use, but manufacturing steps and material costs increase
Solution Approach 1:
The cage component is completely removed from the device, eliminating the need for separate cage manufacturing and assembly steps. The compressed solid block is formulated and compressed to provide its own structural support and positioning stability.
Solution Approach 2:
The support and positioning functions previously provided by the cage are integrated directly into the compressed solid block through optimized compression techniques and material formulation, combining multiple functions into a single component.
3Productivity
If the compressed solid block is placed in the flush water path at an angle, then cleaning and sanitizing effectiveness is improved, but the block may be more prone to disintegration
Solution Approach 1:
The block is positioned at a specific angle (10-45 degrees) relative to the flush water flow to optimize water contact and treatment composition release. This angular positioning maximizes cleaning effectiveness while the compressed structure maintains durability despite the increased mechanical stress.
Solution Approach 2:
The compressed solid block utilizes composite material formulation combining surfactants, sanitizing agents, and structurally robust binders that maintain block integrity even when positioned at angles subject to water flow and potential mechanical stress.
4Reliability
If adhesive materials are used to attach the block to the hanger, then the block remains securely positioned, but the device complexity and material costs increase
Solution Approach 1:
Adhesive materials and attachment mechanisms are completely removed from the device structure. The compressed solid block is designed to hang securely from the toilet bowl rim through its own compressed structure and weight, eliminating the need for adhesives or complex attachment systems.
Solution Approach 2:
The compressed solid block provides its own attachment security through its compressed structure and weight, hanging directly from the toilet bowl rim without requiring external adhesives or attachment mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
The present invention relates to a cageless lavatory dispensing device comprising a hanger (10) and a compressed solid block (50) . 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.
