Buoyant Pool Lounge Chair With Tilted Cup Holders for Spill Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buoyant pool lounge chairs lack stability and comfort, often overturning when occupants shift, and fail to prevent liquid spills in cup holders during use.
Innovation Solution
A buoyant pool lounge chair design featuring an open chair frame with adjustable buoyant cushions, rear and front pivotal coupling assemblies, and cup holders with a forward tilt to maintain stability and prevent spills, allowing for upright, semi-reclining, and reclining positions while floating in water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If buoyant cushions are used to provide comfort and support, then the chair can support occupants in upright, semi-reclining, or reclining positions, but the chair may overturn when the occupant shifts or turns due to center of buoyancy changes
Solution Approach 1:
The chair employs pivotal coupling assemblies that allow dynamic adjustment of the seat and backrest relative to each other, enabling the structure to adapt to occupant position changes while maintaining stability. The pivotal connections permit controlled movement and repositioning without compromising overall structural stability.
Solution Approach 2:
The chair design incorporates adjustable buoyant cushions and pivotal connections that allow changes in the center of buoyancy position according to occupant needs. By enabling parameter changes in cushion positioning and structural orientation, the chair maintains stability across multiple seating configurations.
2Ease of operation
If cup holders are provided in arm rests for convenience, then occupants can hold beverages, but liquid spills occur when the chair floats or occupant moves
Solution Approach 1:
The cup holders are pre-configured with a forward tilt angle of 20-40 degrees during manufacturing. This preliminary angular adjustment ensures that beverages remain stable during chair movement or occupant repositioning, preventing spills before they occur.
Solution Approach 2:
The forward tilt of the cup holder creates a counterbalancing effect that opposes the natural tendency of liquid to spill when the chair moves or tilts. By designing the cup holder at an angle, the system preemptively counteracts the harmful spilling effect.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances stability and comfort by preventing the chair from overturning and mitigates liquid spills in cup holders, providing a secure and convenient floating lounging experience.

AI summary
A buoyant pool lounge chair is disclosed. In one embodiment of the buoyant pool lounge chair, frame members collectively form an open chair frame with buoyant cushions forming a chair seat and a backrest as well as a left arm rest and a right arm rest. The left arm rest and the right arm rest are each intersected by a cup holder. A recess in the cup holder has a forward tilt relative to a horizontal axis having an angle between approximately 20 degrees and approximately 40 degrees toward the front end of the buoyant pool lounge chair. In operation, when the buoyant pool lounge chair is supporting a person while the buoyant pool chair is floating in water, the forward tilt of the cup holder provides a compensating-leveling mechanism that mitigates spilling of liquid in the cup when the cup is placed within the cup holder.
