In-Cistern Floatation Device for Delayed Agent Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-cistern dissolving toilet blocks and cleansing agents tend to concentrate at the bottom of the cistern, leading to inefficient distribution and reduced deodorizing effect when flushed, as the more concentrated cleanser is flushed away first, leaving diluted agents in the toilet bowl.
Innovation Solution
A device that delays the introduction of the cleaning/deodorizing agent until the last part of the flushing cycle, using floatation systems operated by rising and falling water levels to control the release of treated water around the toilet bowl, ensuring a consistent, concentrated dosage is delivered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If in-cistern dissolving toilet blocks are placed in the cistern to dissolve and defuse throughout the water, then the cleanser and colorant are distributed in the cistern water, but the more concentrated cleanser settles at the bottom of the cistern and is flushed away first with the waste, leaving diluted agent in the toilet bowl
Solution Approach 1:
The device pre-mixes the liquid agent with cistern water in a contained reservoir before the flush cycle, ensuring the agent is ready in the correct concentration and position to be released at the optimal moment (during the last part of the flush) when it can effectively clean the bowl without being washed away immediately
2Stability of the object's composition
If liquid agent is diffused throughout the cistern water between flush cycles, then the agent is distributed in the cistern, but the device cannot keep treated water separate from untreated water between flushing cycles
Solution Approach 1:
The device divides the cistern water into two distinct segments: untreated cistern water and treated liquid agent, maintaining them as separate phases within the reservoir structure until the flush cycle begins, at which point the pre-mixed treated water is released as a distinct stream into the toilet bowl
3Quantity of substance
If the device delays introduction of the agent until the last part of the flushing cycle, then a concentrated dosage is delivered to the bowl, but the device must be secured in a stable position to be partially submerged below the water line
Solution Approach 1:
The device employs buoyancy forces to counteract gravity, allowing it to float at the correct position in the cistern with the reservoir partially submerged below the water line, maintaining a stable equilibrium position that enables delayed release of the concentrated agent during the flush cycle
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
This solution provides a deeper colored and stronger deodorizing effect in the toilet bowl by releasing a concentrated cleansing agent only during the last part of the flushing cycle, improving upon existing products by ensuring a 360-degree cleaning and reducing chemical usage.
Implementation Method 1
using floatation systems operated by rising and falling water levels to control the release of treated water

AI summary
A refillable, stand-alone in-cistern device that is activated only by the rising and falling of the water in the cistern that will delay the introduction of a concentrated dose of liquid cleansing agent into the last part of the flush cycle of the toilet, thereby delivering a wide range of improved cleaning and deodorising consumer benefits. The invention only requires securement in any convenient position inside the cistern wall and requires no other customer installation maintenance.
