Swimming Pool Frame Joint With Integrated Locking Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Above-ground swimming pools with frame structures lack reliable mechanical connections between side pipes and support joints, making them unsafe due to the risk of disconnection under wave impact, especially without additional mechanical fittings.
Innovation Solution
A joint for a swimming pool frame featuring a leg pipe holder, side pipe holder, and a locking mechanism with a locking pin that extends through a locking hole and connecting hole to securely hold the side pipes in place, providing enhanced stability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional mechanical connection structures or fittings are used to fix the side pipes and leg pipes to the support joints, then the connection reliability improves, but the device complexity increases
Solution Approach 1:
The locking pin is integrated into the support joint as a unified structure, merging the connection function with the joint body. This eliminates the need for separate mechanical fittings while maintaining reliable connection through the locking mechanism that engages with the side pipe and joint body simultaneously
Solution Approach 2:
The locking pin acts as an intermediary element between the side pipe and the joint body, providing a mechanical locking function without requiring complex external fittings. The locking pin transfers and secures the connection forces between these two components
2Device complexity
If no additional mechanical connection structures are used, then the device complexity is reduced, but the connection reliability deteriorates due to wave impact
Solution Approach 1:
The locking mechanism is merged into the joint body structure itself, providing reliable mechanical connection without adding external complex fittings. The integrated design maintains simplicity while ensuring secure connection under wave impact through the locking pin engagement
3Strength
If a locking mechanism with locking pin is added to secure the side pipes, then the connection strength improves, but the ease of assembly deteriorates
Solution Approach 1:
The locking pin is pre-positioned within the joint body during manufacturing, so that during assembly only the insertion action is required. The alignment features and guiding structures prepare the components in advance to facilitate easy engagement of the locking mechanism without complex assembly steps

AI summary
A joint for a swimming pool frame, and a swimming pool including the joint are provided. The joint includes a joint body including a leg pipe holder configured to have a leg pipe of the swimming pool frame inserted into the leg pipe holder. The joint also includes a side pipe holder configured to have a side pipe of the swimming pool frame inserted in the side pipe holder. A locking hole is formed through the side pipe holder. The joint body also includes a locking part including a locking pin configured to extend through the locking hole and through a corresponding connecting hole in the side pipe, thereby holding the side pipe to the side pipe holder.
