Adjustable Folding Cabana Hood with Multi-Position Control Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible cabanas lack an adjustable fabric hood and a secure, heavy frame to withstand wind and prevent theft, often being lightweight and easily portable but also easily stolen or unstable in windy conditions.
Innovation Solution
A collapsible cabana with a frame that includes legs for support, a seat, adjustable support members, and a control rod system to adjust the fabric hood to full, partial, or no shade positions, along with a lockable storage cabinet for security, using a guide rail with stops to manipulate the hood's position and a sturdy frame made of natural or synthetic wood or plastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lightweight frame is used for the cabana, then ease of transport and setup is improved, but resistance to wind and theft prevention deteriorates
Solution Approach 1:
The support members are designed to be movable between a first position (providing shade) and a second position (collapsed), allowing the cabana to adapt between providing protection and facilitating transport. This dynamic design resolves the contradiction by making the structure adaptable to different operational states rather than being permanently fixed in one configuration.
Solution Approach 2:
The frame is divided into multiple support members (front support member, rear support member, and intermediate support member) that can independently move between positions. This segmentation allows different parts of the structure to be adjusted independently, enabling the cabana to maintain stability when needed while being easily transportable when required.

3Device complexity
If a fixed hood position is used for the cabana, then structural simplicity is improved, but adaptability to different user preferences deteriorates
Solution Approach 1:
The support members are designed to be movable between a first position (providing shade) and a second position (collapsed), allowing the cabana to adapt between providing protection and facilitating transport. This dynamic design resolves the contradiction by making the structure adaptable to different operational states rather than being permanently fixed in one configuration.
Solution Approach 2:
The support members serve multiple functions: they provide structural support for the hood, enable adjustment between different shade positions, and can be collapsed for transport. This multi-functionality allows a single structural element to address multiple needs, resolving the contradiction between simplicity and adaptability.
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 cabana provides adjustable shade options, enhanced security through a lockable storage cabinet, and stability against wind, making it difficult to steal or move without effort, while ensuring protection from the sun and wind.
Implementation Method 1
a control rod adapted to slide on said guide rail and adjustably secured to one of said stops, said rod having at least one upright rod portion pivotally attached to said front support member
Implementation Method 2
manipulating said control rod causes said cabana fabric to be fully extended when said rod is secured in said front stop, to be partially collapsed when said rod is secured one of said at least one intermediate stops, and to be fully collapsed when said rod is secured in said rear stop

AI summary
An adjustable folding cabana having a frame with legs is disclosed. A seat is supported on said frame. A front support member, a rear support member and an intermediate support member support a cabana fabric roof. The front support member is movable between a rear support position, an intermediate support position and a front support position. A guide rail is attached to the frame beneath said seat which has a front stop, an intermediate stop and a rear stop. Manipulating a control rod causes a cabana fabric hood to be fully extended when the rod is secured in the front stop, to be partially collapsed when the rod is secured in the intermediate stop, and to be fully collapsed when the rod is secured in the rear stop.
