Solution Overview

Problem

Conventional coolers lack an effective solution for maintaining the temperature of contents over an extended period while being portable and waterproof, especially when subjected to various orientations or inverted positions.

Innovation Solution

The design incorporates a waterproof closure, an outer shell, an inner liner, and a freely floating insulating layer between the two, with the insulating layer being made of a closed-cell foam to maintain temperature and prevent liquid leakage, and features such as handles and straps for enhanced portability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a conventional cooler design is used, then portability is achieved, but temperature maintenance over extended periods and waterproof performance are compromised

Engineering Contradiction:
Improvetemperature maintenanceVSAvoidwaterproof performance
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The cooler is divided into distinct functional layers: an outer shell for structural integrity, a middle insulation layer for thermal management, and an inner waterproof liner for liquid containment. This segmentation allows each layer to optimize its specific function without compromising the others, achieving both temperature maintenance and waterproof reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cooler employs composite construction combining rigid outer shell material (for durability and structure), insulating material (for thermal isolation), and waterproof liner material (for liquid resistance). This multi-material composite approach resolves the contradiction by integrating the strengths of different materials to achieve both thermal performance and waterproof reliability simultaneously.

Inventive Principle:
Principle #40Composite materials

2Ease of operation

If the cooler is designed for portability with handles and straps, then ease of carrying is improved, but structural integrity and waterproof sealing may be compromised

Engineering Contradiction:
Improveease of carryingVSAvoidstructural integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The cooler incorporates removable and adjustable carrying components (handles and straps) that can be configured or removed based on transport needs. This dynamic design allows the cooler to maintain structural integrity when carried while preserving the ability to adapt to different portability requirements, without permanently compromising the waterproof sealing through fixed attachment points.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If the insulating layer is attached to the shell and liner, then structural stability is improved, but thermal performance and waterproofing are reduced

Engineering Contradiction:
Improvestructural stabilityVSAvoidthermal performance
Core Design Contradiction:
Stability of the object's compositionVSTemperature

Solution Approach 1:

The insulating layer is extracted from direct attachment to the shell and liner, allowing it to float freely within the cooler cavity. This extraction eliminates thermal bridges that would conduct heat between the outer shell and inner liner, thereby improving thermal performance. The insulation remains structurally stable through its positioning within the cavity rather than through rigid attachment.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The freely floating insulating layer acts as an intermediary between the outer shell and inner liner, providing thermal isolation without direct physical connection. This intermediary positioning prevents heat transfer pathways while maintaining the structural framework of the cooler, resolving the contradiction between structural stability and thermal performance.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An insulating device can include an aperture having a waterproof closure which allows access to the chamber within the insulating device. The closure can help prevent any fluid leakage into and out of the insulating device if the insulating device is overturned or in any configuration other than upright. The closure may also prevent any fluid from permeating into the chamber if the insulating device is exposed to precipitation, other fluid, or submersed under water. This construction results in an insulating chamber that is substantially impervious to water and other liquids when the closure is sealed.
