Elliptical Pool Frame with Wall-Mounted Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable above-ground pools face issues with rectangular frames being heavy, space-consuming, and unsafe due to unsecured steel tubes, circular frames having limited length, and elliptical frames lacking stability and proper support, while filtration systems are often cumbersome and ineffective.
Innovation Solution
A portable pool with an elliptical frame featuring a support frame and flexible liner, including arcuate and straight frames connected via elastic pins, and a wall-mounted filtration apparatus with a filtering cover to ensure stability, safety, and efficient water filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rectangular frame is used, then structural strength is improved, but weight increases and space occupation increases
Solution Approach 1:
The patent applies curvature by transitioning from a rectangular frame to an elliptical frame structure. The elliptical shape distributes structural loads more efficiently along the curved perimeter, maintaining strength while reducing the total amount of material required compared to rectangular geometry with its concentrated corner stresses and longer perimeter.
2Strength
If rectangular frame is used, then structural strength is improved, but installation space is limited
Solution Approach 1:
The elliptical frame utilizes curved geometry to optimize space utilization. The curved sides allow the pool to fit into narrower locations compared to rectangular pools with fixed 90-degree corners, while the elongated shape along the major axis maximizes pool length within available space.
Solution Approach 2:
The elliptical frame employs asymmetric geometry with a defined major axis and minor axis, allowing the pool to be oriented optimally in available spaces. The elongated shape along the major axis provides greater length while the compressed minor axis reduces the space footprint in perpendicular directions.
3Ease of manufacture
If elliptical frame without full support is used, then ease of manufacture is improved, but structural stability deteriorates
Solution Approach 1:
The elliptical frame is segmented into multiple sections along its perimeter, with support members strategically positioned at intervals rather than continuous support. This segmentation allows for easier manufacturing and assembly while maintaining structural stability through the distributed support points that prevent excessive deflection of the flexible liner.
Solution Approach 2:
The frame structure implements local quality by providing concentrated support members at specific locations around the elliptical perimeter rather than uniform continuous support. This allows the structure to maintain stability where needed while reducing material usage and manufacturing complexity in other areas.
4Ease of manufacture
If unsecured steel tubes are used, then ease of manufacture is improved, but safety deteriorates
Solution Approach 1:
Connection elements serve as intermediaries between the steel tubes of the elliptical frame, providing secure mechanical fastening that prevents the tubes from separating or becoming unsecured. These connection elements maintain assembly simplicity while eliminating safety hazards associated with unsecured tubes.

AI summary
A pool with an elliptical frame is disclosed. The pool includes a support frame and a flexible pool liner which is supported by the support frame and is used for containing water. The support frame includes a horizontal and substantially elliptical upper frame. A plurality of vertical support members and oblique support members are used for supporting the upper frame. Two opposite ends of the upper frame are arranged two opposite arcuate frames along the major axis direction of the elliptical upper frame. Two opposite parallel straight frames having the same length are respectively coupled between the two arcuate frames. The arcuate frames and the straight frames form the closed upper frame. The wall-mounted filtration apparatus is arranged on the pool using the connecting threads positioned on the water outlet of the pool.
