Convertible Cooler Bed With Fold-Out Sleeping Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When traveling, especially in vehicles, the limited space makes it difficult to accommodate both a cooler for temperature-controlled food storage and a bed, as both occupy significant space, often forcing a compromise between the two.
Innovation Solution
A convertible cooler with a fold-out bed extension that transforms into a bed platform, allowing the cooler to serve as a standard cooler and a multi-part bed, with removable leg assemblies for adjustable support and storage, enabling use in vehicles and outdoor settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cooler and a bed are both brought for traveling, then temperature-controlled food storage and sleeping accommodations are provided, but the space required in the vehicle increases significantly
Solution Approach 1:
The patent combines a cooler and a bed into a single integrated unit. The cooler body serves as the base structure, and the bed components (panels, headboard, footboard) attach to and fold from the cooler, creating a unified dual-function device that eliminates the need for separate cooler and bed items.
Solution Approach 2:
The cooler is designed to perform multiple functions: it serves as a temperature-controlled storage unit when the bed components are stowed, and it transforms into a complete bed structure when the panels and headboard/footboard are deployed. This multi-functionality allows one device to replace what would traditionally require two separate items.
2Area of moving object
If the bed extension is unfolded to extend from the top of the cooler, then sleeping surface area is increased, but the device complexity increases
Solution Approach 1:
The bed structure is divided into separate modular components: the cooler body serves as the base, while the bed panels, headboard, and footboard are distinct attachable elements. This segmentation allows each component to be independently manufactured, attached, and stored, simplifying the overall system while enabling extended sleeping surface area.
3Stability of the object's composition
If leg assemblies are added to support the bed extension, then stability of the bed structure is improved, but the device complexity and number of parts increase
Solution Approach 1:
The leg assemblies are designed to be adjustable and reconfigurable rather than fixed. They can be positioned at different locations and angles to accommodate various ground conditions and bed configurations, providing stability while maintaining flexibility in the overall system design.

Function Achieved in This Case
The solution provides a compact, versatile solution for space-constrained environments, allowing for both temperature-controlled storage and sleeping accommodations, enhancing travel convenience by optimizing space utilization.
Implementation Method 1
a cooler body, a thermally insulated cooler lid... so that items placed within the interior storage compartment are thermally insulated from the environment

AI summary
A convertible cooler comprises a cooler body, a lid having a top surface and a rear connector part, a bed extension having an adjoining edge and a sleeping surface, a bed extension connector pivotally connecting the adjoining edge to the rear connector part to rotate the bed extension between a stowed position, in which the bed extension rests flat upon the top surface of the lid, and an extended position, in which the sleeping surface of the bed extension is substantially coplanar with the top surface of the lid, and a leg assembly connected to the bed extension and adjustably supporting the bed extension above ground at a level that places the sleeping surface substantially coplanar with the top surface of the lid when in the extended position. The lid top surface and the sleeping surface of the bed extension are sized to permit a person to sleep thereon.
