Satchel Dispenser Plenum Chamber Water Flow Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The dispensing rate of dispensers in recreational water systems is affected by water conditions, leading to inconsistent dispersant release and potential staining due to turbulent or stagnant water flows, which can cause dispersants to be released at unwanted rates or not be adequately absorbed, resulting in pool staining.
Innovation Solution
A satchel dispenser with nested containers and a plenum chamber that provides a tortuous water path for dispersants, isolating them from direct water flow effects and allowing controlled release, preventing immediate contact with the main water body and reducing oxidation and staining risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dispenser with fixed or variable water ports is placed in different areas of the pool, then the dispersant can be released into the water body, but the dispersant rate changes substantially based on water flow conditions (turbulent vs. placid areas)
Solution Approach 1:
The dispenser is divided into an outer housing and an inner housing with nested containers, creating separate chambers (outer dispersant chamber and plenum chamber) that segment the water flow path and isolate the dispersant release mechanism from external water conditions
Solution Approach 2:
The plenum chamber acts as an intermediary between the external water environment and the dispersant release point, buffering the effects of turbulent or placid water conditions and providing a controlled intermediate environment for consistent dispersant dissolution
2Productivity
If the dispersant rate is too high in rapid water flow areas, then the dispersant is released quickly, but the dispersant is not absorbed or diluted within the dispenser causing it to be carried into the body of water before absorption, which can cause staining
Solution Approach 1:
The dispenser provides preliminary action by allowing the dispersant to dissolve and be absorbed in the protected plenum chamber before release, ensuring proper dilution occurs within the dispenser rather than after release into the pool water
Solution Approach 2:
The plenum chamber serves as an intermediary environment where the dispersant can be properly dissolved and diluted by water that has already passed through the outer housing, preventing direct contact with high-velocity pool water that would cause staining
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 satchel dispenser maintains consistent dispersant release rates by mitigating external water conditions, preventing pool staining and ensuring effective dispersant absorption, while maintaining the appearance of the dispenser by hiding stains from view.
Implementation Method 1
The satchel dispenser provides a tortuous water path in and out of the satchel dispenser, which can include viscous damping as the water flows through the satchel dispenser
Implementation Method 2
the satchel dispenser isolates the dispersants in the plenum chamber by providing a tortuous water path in and out of the satchel dispenser
Implementation Method 3
water ports for ingress and egress of water with the egress of water carrying a dispersant into the body of water
