Pool Cover Ventilation Cells for Chlorine Gas Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pool covers face issues with unaccounted chlorine build-up leading to inner pool surface deterioration and damage to pool apparatus, as existing solutions fail to effectively vent chlorine gas and manage evaporation.
Innovation Solution
A pool cover arrangement featuring a body with a first set of closed air-cells for insulation and a second set of open air-cells with ventilation passages, where the inlet and outlet are offset to allow chlorine gas venting while minimizing water exposure to sunlight, and the second set of cells is inset to expose an increased water surface area for gas release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If pool covers are used to limit evaporation and manipulate pool temperature, then heat insulation is improved, but chlorine build-up increases causing pool surface deterioration and apparatus damage
Solution Approach 1:
The pool cover is divided into multiple cells with different functions: some cells are closed for heat insulation while others are open with ventilation passages for chlorine gas release. This segmentation allows simultaneous achievement of heat insulation and chlorine venting without compromising either function.
Solution Approach 2:
Different regions of the pool cover have different properties: the closed cells provide thermal insulation properties while the open cells with ventilation passages provide gas venting properties. This local differentiation of quality allows the cover to address multiple problems simultaneously in different locations.
2Object-generated harmful factors
If ventilation passages are added to vent chlorine gas, then chlorine build-up is reduced, but water exposure to sunlight increases during middle of the day
Solution Approach 1:
The ventilation passages are positioned asymmetrically with inlets and outlets at different locations and orientations. This asymmetric arrangement allows chlorine gas to vent effectively while the geometry of the passages and their positioning minimizes direct sunlight exposure to the water through the ventilation openings during midday hours.
3Object-generated harmful factors
If the second set of cells is inset to expose increased water surface area for gas release, then chlorine venting is improved, but structural complexity increases
Solution Approach 1:
The pool cover structure is segmented into multiple cell types (closed cells and open cells with ventilation passages) arranged in a systematic pattern. This segmentation, while increasing structural complexity, provides a modular approach that facilitates manufacturing and allows for effective chlorine venting through the distributed ventilation passages.
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 solution effectively reduces chlorine build-up by allowing gas venting and limits evaporation, protecting the pool surface and apparatus from damage while maintaining heat insulation and reducing direct water exposure to sunlight.
Implementation Method 1
the first set of cells provide a first area for floating on water
Implementation Method 2
each of the cells in the second set of the cells is an open air-cell that provides a ventilation passage having an inlet and an outlet for allowing chlorine gas to vent from the water
Implementation Method 3
the inlet and the outlet of each ventilation passage are offset with respect to vertical, when the body is positioned on the water, the inlet and the outlets being offset to limit direct water exposure to sunlight during the middle of the day
Implementation Method 4
the cells of the second set of cells each have a downwardly directed lower wall for directing water downwardly through the ventilation passage to limit the likelihood of water accumulation within the ventilation passage

AI summary
In one preferred form there is provide a pool cover arrangement (10) comprising: a body (12) having a first set of cells (24) and a second set of cells (26). The first set of cells (24) provide a first area (35) for floating on water. The first area (35) comprises the forward facing areas (27) of the first set of cells (24). The second set of cells (26) are spaced away from the forward facing areas (27), so as to sit above the water, when the first set of cells (24) sit on the water. In other preferred forms ventilation holes and layers are provided.
