U-Shaped Cooler Handle Nesting for Compact Wheeled 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 footprints when not in use.
Innovation Solution
A travel cooler with a wheeled platform and an insulated container that can be selectively coupled and uncoupled, featuring inflatable sidewalls, a drain conduit, and a handle system that allows for compact storage and easy transportation of both perishable and non-perishable items, with the ability to collapse for reduced dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wheeled cooler or cart is used to transport beach items, then mobility is improved, but storage space consumption increases significantly when not in use
Solution Approach 1:
The cooler incorporates an extendable handle that can be retracted into the cooler body when not in use. This dynamic feature allows the handle to transition between an extended position for easy maneuvering and a retracted position for compact storage, directly resolving the contradiction between mobility and storage space consumption.
2Productivity
If a large-capacity cooler is used to carry all beach items in a single trip, then transportation efficiency is improved, but the device occupies excessive space when stored
Solution Approach 1:
The handle is nested within the cooler body when not in use, with the handle cavity providing internal storage space for small items. This nesting arrangement allows the cooler to maintain large capacity for beach items while minimizing its overall footprint during storage by accommodating the handle inside the main body.
3Strength
If a rigid handle structure is used for the wheeled cooler, then structural strength is improved, but the device cannot be compacted for storage
Solution Approach 1:
The handle is designed with a telescoping mechanism that maintains structural integrity when extended for use but can be retracted into the cooler body for compact storage. This dynamic structure resolves the contradiction by providing rigidity when needed while enabling compaction when not in use.
Solution Approach 2:
The handle structure incorporates an internal cavity that nests the handle within the cooler body during storage. This nesting arrangement allows the rigid handle to be accommodated inside the cooler, minimizing external dimensions while maintaining structural strength when the handle is extended for operation.

AI summary
A travel cooler, includes a body comprising a base, sidewalls, and a lid connected together to define an interior, insulated containment space for holding cooler items. A lengthwise dimension of the cooler extends between opposite ends of the cooler, and the body defines recessed exterior surface slots extending along a lengthwise extent of the cooler. The cooler further includes a U-shaped handle having two legs connected by a handle portion. The cooler is transitionable between a first configuration, in which the legs of the U-shaped handle extend a substantial length from the body of the cooler, and a second configuration, in which the legs of the U-shaped handle are received within the recessed exterior surface slots extending along a lengthwise extent of the cooler, the handle portion extending in close proximity to an end of the body of the cooler.
