Buoyant Pool Lounge Chair Frame for Stable Float Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buoyant pool lounge chairs lack stability, often overturning when the center of buoyancy shifts due to occupant movement, necessitating an improved design that maintains stability and functionality while leveraging existing pool floats.
Innovation Solution
A buoyant pool lounge chair frame with a pod frame featuring a rigid base, inverted parabolic surface, and centra, which engages a flotation device in a load-bearing relationship, providing enhanced stability through a releasable connection with the pool float, and utilizing materials like closed-cell foam and PVC for structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional buoyant lounge chairs are used, then they provide basic flotation and seating, but they lack stability and overturn when the center of buoyancy shifts due to occupant movement
Solution Approach 1:
The pod frame is divided into distinct functional segments: a rigid base portion for structural support, a front support portion with inverted parabolic surface for anterior engagement, and a rear support portion with centra for posterior engagement. This segmentation allows each part to independently contribute to stability while distributing loads effectively, preventing overturning even when the occupant shifts position.
Solution Approach 2:
The invention combines the pod frame structure with existing pool floatation devices into an integrated seating system. The frame merges structural support elements (base, front support, rear support) with the buoyant float, creating a unified stable platform that leverages the float's inherent buoyancy while adding geometric stability through the inverted parabolic and centra configurations.
2Stability of the object's composition
If a rigid frame structure is used to improve stability, then overturning is prevented, but assembly and storage become more complex
Solution Approach 1:
The frame is segmented into modular components (base portion, front support portion, rear support portion) that can be independently manufactured and then assembled together. This segmentation simplifies manufacturing and assembly while maintaining the structural integrity and stability of the complete frame when assembled.
3Stability of the object's composition
If sufficient buoyancy material is added to maintain stable upright orientation, then stability improves, but the chair becomes heavier and less functional
Solution Approach 1:
The pod frame acts as an intermediary structural element between the occupant and the floatation device. Rather than adding more buoyancy material to the float itself, the frame provides geometric stability and load distribution, allowing the existing float to provide sufficient buoyancy without additional weight.

AI summary
A buoyant pool lounge chair frame and buoyant pool lounge chair using the same are disclosed. In one embodiment of the buoyant pool lounge chair frame for supporting a floatation device while the buoyant pool chair frame is floating in water, a pod frame is provided including a rigid base portion and a window having a vertical opening therethrough. A substantially inverted parabolic surface is positioned at the front of the pod frame and a centra including a rigid back is positioned at the rear of the pod frame such that the window is therebetween. The pod frame is sized to accept a floatation device such that the substantially inverted parabolic surface and the centra engage the floatation device in a load-bearing relationship.
