Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coolers lack an effective, portable, and waterproof solution for maintaining contents at desired temperatures while ensuring ease of access and mobility.
Innovation Solution
A non-rigid, portable insulating device with a waterproof closure, featuring an outer shell, an inner liner, and a freely floating insulating layer, designed to maintain temperature and prevent liquid leakage, equipped with handles and straps for easy carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional coolers are designed to be portable with straps and handles, then ease of transport is improved, but waterproof performance deteriorates
Solution Approach 1:
The patent employs a flexible waterproof liner made of laminated material (such as TPU-coated nylon) that forms the inner chamber and closure components. This flexible waterproof film maintains water resistance while allowing the cooler to be folded, collapsed, and equipped with straps and handles for portability, directly resolving the contradiction between ease of transport and waterproof performance.
2Strength
If rigid materials are used for cooler construction, then structural strength is improved, but portability deteriorates
Solution Approach 1:
The patent utilizes composite materials including TPU-coated nylon fabric combined with insulation layers (such as foam or air-trapped fibers) to create a structure that is both strong and lightweight. The laminated construction provides structural integrity without the weight of rigid materials, enabling portability while maintaining strength.
Solution Approach 2:
The flexible waterproof liner and outer shell construction provide sufficient structural strength to contain contents and maintain shape during use, while the flexible nature allows for easy carrying via integrated straps and handles, resolving the strength-portability contradiction.
3Ease of manufacture
If the cooler is designed as a single rigid unit, then manufacturing simplicity is improved, but adaptability deteriorates
Solution Approach 1:
The patent divides the cooler into separable components including a removable waterproof liner, an outer shell, insulation layers, and modular closure systems. This segmentation allows each component to be manufactured independently using simple processes, then assembled into various configurations for different uses, thereby improving both manufacturing simplicity and adaptability.
Solution Approach 2:
The cooler incorporates dynamic, adjustable features such as removable straps, adjustable handles, and flexible closure mechanisms that can be configured for different carrying methods and access patterns. This dynamic design maintains manufacturing simplicity while significantly improving adaptability to various user needs and environments.

AI summary
An insulating device may include an outer shell, an inner liner forming a storage compartment, an insulating closed cell foam layer positioned in between the outer shell and the inner liner, an opening configured to allow access to the storage compartment, and a closure configured to seal the opening. A temperature of the storage compartment may be configured to gain between 0.5 and 1.5° F./hr from 0° F. to 50° F. while the insulating device is in an approximately 100° F. ambient environment and the opening is sealed by the closure.
