Stackable Travel Cooler Layout for High Capacity, Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices for transporting beach items are cumbersome, requiring multiple trips and occupying excessive space, as they lack sufficient capacity to carry both perishable and non-perishable items efficiently and have large storage requirements when not in use.
Innovation Solution
A travel cooler with a wheeled platform and an insulated container that can be coupled and uncoupled, featuring inflatable sidewalls, a drain conduit, and a handle system that allows for compact storage and efficient transportation of both perishable and non-perishable items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a mobile device is designed to transport both perishable and non-perishable items with sufficient capacity for a family or group, then the transportation capacity is improved, but the device requires a large amount of storage space when not in use
Solution Approach 1:
The mobile device is divided into separate functional modules: a cooler body for perishable items, a separate cargo area for non-perishable items, and a detachable handle assembly. This segmentation allows each component to be optimized independently and facilitates compact stacking when not in use, resolving the contradiction between transportation capacity and storage space requirements
Solution Approach 2:
The design enables components to be nested within each other during storage - the cargo area can be positioned within or adjacent to the cooler body, and the handle assembly can be collapsed or detached. This nesting capability allows the device to occupy minimal storage space while maintaining full transportation capacity when deployed
2Productivity
If a mobile device is designed with large capacity to transport all beach items in a single trip, then the productivity is improved, but the device becomes cumbersome and requires multiple trips anyway
Solution Approach 1:
By segmenting the device into modular components (cooler body, cargo area, handle assembly), the design achieves large total capacity without creating a single cumbersome unit. Each module can be independently maneuvered or combined, maintaining ease of use while maximizing transport capacity in a single trip
Solution Approach 2:
The handle assembly is designed to be extendable and retractable, allowing the device to adapt its configuration based on whether it is being transported or stored. This dynamic adjustment reduces the effective bulk during transport while maintaining full capacity, improving productivity without permanent increase in device complexity
3Quantity of substance
If a mobile device is designed with sufficient capacity for family or group items, then the transportation capacity is improved, but the device takes up large space in the car during transport
Solution Approach 1:
The modular components are designed to nest within each other or stack compactly when not in use. The cargo area can be collapsed or positioned within the cooler body footprint, and the handle assembly can be retracted, allowing the entire device to occupy minimal space in a car trunk or cargo area while maintaining full transportation capacity at the destination
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
Enables single-trip transportation of a substantial amount of beach items while significantly reducing storage space requirements when not in use, thanks to the collapsible design and detachable components.
Implementation Method 1
The inflatable walls define an enclosed, insulated space for receiving and preserving perishable food items
Implementation Method 2
The base includes a drain conduit for removal of liquid from the insulated container

AI summary
A stacked arrangement of travel coolers including a plurality of travel coolers arranged in a series of stacking pairs and a method of stacking the travel coolers. Each travel cooler includes a base with a bottom surface, a pair of wheels mounted to the base, an insulated container, a front end of the base and a rear end of the base. Each stacking pair includes an upper travel cooler disposed on top of a lower travel cooler. The bottom surface of the base of the upper travel cooler rests upon the bottom surface of the base of the lower travel cooler. Alternatively, a surface of a lid of the upper travel cooler rests upon a surface of a lid of the lower travel cooler. The front end of the upper travel cooler is disposed over and generally aligned with the rear end of the lower travel cooler.
