Sheathed Frame Pool Junctions Prevent Rust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Above ground frame pools suffer from rust generation due to friction damage of anti-rust coatings at junctions and water infiltration through gaps between components, leading to premature corrosion.
Innovation Solution
A sheathed frame pool design featuring sheaths at junctions between horizontal side pipes, support pipes, and T-shaped pipe joints, along with ring structures and pins for secure fastening and water prevention, forming a hollow pipe structure with annular grooves and fixing rings to prevent rust and water ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-rust coating is applied to the outer surfaces of horizontal side pipes, support pipes and T-shaped pipe joints, then rust prevention is achieved, but the coating is susceptible to damage due to mutual frictions at junctions during assembly and use
Solution Approach 1:
The patent introduces a T-shaped rubber sleeve as an intermediary component between the metal pipes and T-shaped pipe joint. This rubber sleeve acts as a mediator that absorbs friction during assembly and pool usage, preventing direct contact and friction between the coated metal surfaces, thereby protecting the anti-rust coating from damage while maintaining the structural connection
2Ease of manufacture
If horizontal side pipes and support pipes are inserted into T-shaped pipe joints to form the pool structure, then the pool framework is assembled, but gaps exist at junctions allowing rainwater and spilled water to flow into pipe interiors causing rust
Solution Approach 1:
The patent employs a T-shaped rubber sleeve that functions as a flexible sealing element. This rubber sleeve conformally fits around the inserted pipes and seals the gap between the horizontal side pipes/support pipes and the T-shaped pipe joint, preventing water infiltration while accommodating the assembly configuration and structural requirements
3Ease of operation
If the pool components are designed with simple insertion joints for easy assembly, then ease of installation is achieved, but friction during insertion and shaking damages the anti-rust coating
Solution Approach 1:
The T-shaped rubber sleeve serves as a protective intermediary that enables simple insertion joints to function without damaging the anti-rust coating. The rubber material provides a low-friction interface during insertion and continues to protect against friction during pool usage, maintaining both ease of installation and coating integrity

AI summary
The present invention provides a sheathed frame pool, comprising a support frame composed of a plurality of interconnected support components; a pool liner (40) comprising a pool bottom (42) and a pool wall (41) connected to an outer edge of the pool bottom and extends upward, an upper edge of said pool wall being hanging on said support frame and being disposed on an inside of said support frame, and at least one sheath (50) disposed on a junction between at least two of said plurality of interconnected support components. The sheathed frame pool of the present invention has a simple structure, a low cost and convenient installation. Sheaths (50) are respectively provided at the junction of a horizontal side pipe (10) and a T-shaped pipe joint (30) of the frame pool and the junction of a support pipe (20) and the T-shaped pipe joint (30), which can effectively overcome the defect of rust generation on the pipe body caused by the susceptibility to wear of the coating at an outer surface of the horizontal edge pipe and the support pipe due to frequent frictions between the horizontal side pipe and the T-shaped pipe joint and between the support pipe and the T-shaped pipe joint (30) during the installation or use of frame pools in the prior art.
