Solution Overview

Problem

Conventional coolers lack an effective, portable, and waterproof solution for maintaining contents at desired temperatures while being easy to carry and resistant to liquid penetration.

Innovation Solution

A non-rigid insulating device with a waterproof closure, an outer shell, an inner liner, and a freely floating insulating layer, designed to keep contents cool or warm for extended periods, featuring a waterproof zipper assembly and reinforced construction for structural integrity and mobility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If conventional coolers are designed to be portable with smaller shapes and straps, then mobility is improved, but waterproof performance and structural integrity deteriorate

Engineering Contradiction:

ImproveportabilityVSAvoidwaterproof performance

Core Design Contradiction:

Weight of moving objectVSReliability

Solution Approach 1:

The cooler is divided into distinct waterproof components: an outer shell made of waterproof material, a separate waterproof closure system with sealed zipper, and an inner liner that can be removed. This segmentation allows each component to be optimized for waterproof performance while maintaining overall portability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A waterproof closure system acts as an intermediary between the interior and exterior environments, providing a sealed barrier that maintains waterproof performance while allowing controlled access. The closure includes sealed zippers and gaskets that prevent water penetration without compromising the portable design.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If rigid materials are used for cooler construction, then structural integrity is improved, but portability and ease of carrying deteriorate

Engineering Contradiction:

Improvestructural integrityVSAvoidease of carrying

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The cooler employs a flexible outer shell made of durable waterproof fabric or coated material that provides sufficient structural integrity for protection while remaining lightweight and flexible enough for easy carrying. The shell maintains its shape when needed but can be folded or compressed for transport.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The cooler construction combines multiple materials with complementary properties: waterproof fabric or coated material for the outer shell, rigid or semi-rigid insulation material (such as foam) for thermal performance and structural support, and flexible sealing materials for the closure system. This composite approach achieves both strength and portability.

Inventive Principle:

Principle #40Composite materials

3Stability of the object's composition

If insulation layer is firmly attached to shell and liner, then structural stability is improved, but thermal performance and adaptability deteriorate

Engineering Contradiction:

Improvestructural stabilityVSAvoidthermal performance

Core Design Contradiction:

Stability of the object's compositionVSTemperature

Solution Approach 1:

The insulation layer is designed with dynamic attachment characteristics - it can be firmly secured during normal use to maintain structural stability, but can be easily adjusted or repositioned when needed. This dynamic approach allows the insulation to conform to different loading conditions while maintaining thermal performance.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The insulation layer provides varying levels of attachment strength in different locations - firmly attached in areas requiring structural support, while allowing thermal expansion and contraction in areas critical for thermal performance. This localized quality optimization balances structural stability with thermal efficiency.

Inventive Principle:

Principle #3Local quality
