Solution Overview

Problem

Fully assembled ice barrels often exceed the volume capacity of standard shipping containers, leading to wasted space and increased shipping costs, and their weight can pose safety risks when emptying.

Innovation Solution

A modular, collapsible ice barrel design featuring an expandable bladder and semi-rigid exterior wall that can be assembled at the destination, reducing shipping volume and weight, and incorporating insulation to maintain temperature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ice barrels are shipped fully assembled, then structural integrity and functionality are ensured, but shipping volume efficiency deteriorates due to empty space in the interior cavity

Engineering Contradiction:
Improvestructural integrityVSAvoidshipping volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The ice barrel is divided into multiple components: an exterior barrel wall, an interior barrel wall (bladder), and insulative material. These segments can be shipped separately in a collapsed or compressed state, significantly reducing shipping volume. The components are then assembled at the destination to form the functional ice barrel, ensuring structural integrity only when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The interior barrel wall is designed as an expandable bladder that can be inflated or expanded after assembly. This dynamic feature allows the bladder to transition from a compact shipped state to an expanded functional state, optimizing both shipping volume and interior capacity.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If injection molded components are used, then manufacturing precision and durability are improved, but weight increases leading to higher shipping costs

Engineering Contradiction:
Improvecomponent precisionVSAvoidbarrel weight
Core Design Contradiction:
Manufacturing precisionVSWeight of moving object

Solution Approach 1:

The interior barrel wall is constructed as a flexible bladder rather than a rigid injection-molded component. This flexible shell approach significantly reduces weight while maintaining the necessary structural integrity and durability for containing ice and beverages. The bladder can be manufactured using lighter materials and processes compared to traditional rigid injection molding.

Inventive Principle:
Principle #30Flexible shells and thin films

3Ease of operation

If fully assembled barrels are shipped, then product readiness is improved, but shipping cost efficiency deteriorates due to wasted space and size limitations

Engineering Contradiction:
Improveproduct readinessVSAvoidshipping cost
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

By segmenting the ice barrel into shipable components that can be quickly assembled at the destination, the system achieves both cost efficiency and operational readiness. The assembly process is designed to be straightforward, requiring minimal tools or expertise, thus maintaining product readiness while eliminating the waste of shipping empty interior space.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The collapsible and nestable design of the barrel components allows them to be packed efficiently within the shipping container, maximizing space utilization. The exterior barrel wall, interior bladder, and insulative material can be nested or compressed to minimize occupied volume during transport.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A portable and collapsible insulating device kit (301) may be configured to fit within a smaller container for easier shipment. In one example, the assembly may include a base (336), a top wall having an opening, an inner liner (302) configured to extend into the opening of the top wall to form an interior cavity defining a volumetric storage capacity and an exterior wall (303). The container can have a flat configuration defining a length, height, and width. The base, the top wall, the inner liner, and the exterior wall may be configured to be assembled into a portable insulating device. The volume of the container may be less than the volumetric storage capacity of the assembled portable insulating device, and the base, the inner liner, and the exterior wall are configured to be detached from one another and shipped in the container.
