Above Ground Pool Integrated Wall Bottom Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Above ground pools have a high number of welding seams, which increases production complexity and cost, and raises the probability of water leakage due to seams under water pressure.
Innovation Solution
The pool design features side walls extending to the bottom, with a polygonal bottom sheet and integral isosceles trapezoid-shaped side and bottom portions, reducing the number of welding seams and distributing pressure away from critical joints, using a combination of PVC and fabric PVC materials for the sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pool is made by clipping and splicing separate pool bottom and pool wall components, then the pool can be assembled, but the number of welding seams increases which increases production complexity and cost
Solution Approach 1:
The patent merges the pool bottom and pool wall into a single integrated component. The side wall is designed to extend continuously from the pool wall portion down to the pool bottom portion, eliminating the need for separate clipping and splicing operations. This integration reduces the number of welding seams and simplifies the production process while maintaining structural integrity.
2Reliability
If separate pool bottom and pool wall components are used, then assembly is enabled, but the probability of water leakage increases due to multiple welding seams under water pressure
Solution Approach 1:
By integrating the pool bottom and pool wall into a single continuous structure, the patent eliminates multiple welding seams that would otherwise be present at the junction between separate components. This reduces the number of potential leakage points and improves reliability while maintaining ease of assembly.
3Device complexity
If the side wall extends to the bottom of the pool, then the number of welding seams is reduced, but the structural design becomes more complex
Solution Approach 1:
The side wall is segmented into functional portions: a pool wall portion and a pool bottom portion. This segmentation allows the side wall to extend continuously to the bottom while maintaining manufacturability through standardized components. The integral structure is designed with specific geometric features that facilitate production while achieving the goal of reduced welding seams.

AI summary
The present invention provides a above ground pool, comprising a flexible pool body. The flexible pool body comprises: a polygonal bottom sheet that comprises a plurality of edge portions; and a plurality of side sheets, each side sheet comprising a pool sidewall portion and a pool bottom portion, and each of the pool sidewall portions and each of the pool bottom portions being in the shape of an isosceles trapezoid. Each of pool sidewall portion comprises a first upper-base portion, a first lower-base portion and a first middle portion defined between the first upper-base portion and the first lower-base portion, and each of the pool bottom portion comprises a second upper-base portion, a second lower-base portion and a second middle portion defined between the second upper-base portion and the second lower-base portion. The first lower-base portion and the second lower-base portion coincide to define a junction of the pool sidewall portion and pool bottom portion. The first middle portions of the side sheets are successively connected to form a side wall of the above ground pool and the second middle portions are successively connected to form an outer ring of the bottom of the above ground pool. The second upper-base portions of the pool bottom portions are respectively connected to the edge portions of the bottom sheet. In the above ground pool of the present invention, joints are moved to a side wall of the swimming pool or the bottom of the swimming pool as much as possible, thereby reducing the length of joints passing through a heavily stressed area to the greatest extent, simplifying production processes, reducing costs, and reducing the probability of water leakage from the above ground pool.
