Inflatable Pool Cover Dome Design for Debris Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pool covers are difficult to remove in the spring due to debris accumulation and water weight, leading to potential health issues and aesthetic problems.
Innovation Solution
An inflatable pool cover with a dome-like design and securing system using a tether or cable, along with a turnbuckle and reinforced grommets, maintains tautness without tearing and allows for easy removal by preventing debris and water accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional pool cover is used to prevent debris from entering the pool, then the pool is protected from debris, but the cover becomes difficult to remove due to debris accumulation and water weight
Solution Approach 1:
The pool cover is divided into multiple removable sections or panels that can be taken off separately. This segmentation allows users to remove portions of the cover without having to lift the entire heavy, debris-loaded cover at once, making the removal process much easier while maintaining debris protection when the cover is in place.
Solution Approach 2:
The cover design incorporates preliminary drainage features such as channels, grooves, or collection areas that actively prevent water and debris accumulation before it becomes a heavy burden. By providing predetermined paths for water to drain off the cover surface, the system prevents the buildup that would otherwise make removal difficult.
2Stability of the object's composition
If the pool cover is made taut to prevent sagging and debris collection, then the cover remains stable and clean, but the securing system may tear under the tension
Solution Approach 1:
The securing system uses different materials and designs at different locations. The grommets are made of reinforced, tear-resistant material specifically at the stress points where cables attach, while the cover material itself can be lighter. This localized strengthening provides the necessary durability at critical points without requiring the entire system to be overly robust.
Solution Approach 2:
The securing system combines multiple materials with complementary properties: the cover uses a flexible waterproof material, the grommets use reinforced plastic or metal for strength, and the cables use high-tensile steel or nylon. This composite approach allows each component to contribute its optimal properties, achieving both tautness and durability.
3Object-affected harmful factors
If an inflatable pool cover is used to maintain tautness, then the cover prevents debris accumulation, but the inflation system requires additional components and setup complexity
Solution Approach 1:
The inflatable cover incorporates self-inflating features such as one-way valves that allow air to enter but not escape, or materials that expand when exposed to moisture or temperature changes. This self-service capability eliminates or reduces the need for external pumps and complex inflation systems, achieving debris prevention through maintained tautness without proportionally increasing system complexity.

AI summary
An assembly includes an inflatable, dome-like cover that is configured to rest atop an existing swimming pool. The cover has an inflatable portion that repels dirt, debris, water, and snow, preventing such debris from collecting thereon. The cover is produced from heavy duty, yet lightweight plastic or rubber material. The cover may sized and configured to fit a pool of any dimensions. Extending along a perimeter of the inflatable portion is a border about which openings are evenly spaced, through which tethers or cords may be tied for securing the assembly to the pool. At least one air valve is positioned proximal to the outer edge of the cover, enabling a user to inflate the assembly.
