Insulating Container Rotatable Lid and Convertible Strap Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insulating containers are often not durable, with lids that can be lost or broken, handles that protrude and are susceptible to breakage, and ineffective latches, rendering them virtually useless.
Innovation Solution
An insulating container design featuring a rotatable lid with a gasket for a water-resistant seal, a strap assembly with a pivot clip and slider clips for secure attachment, and a convertible shoulder strap and handle configuration, along with a pivot assembly for stable strap rotation, and a drain assembly for easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional insulating containers use simple lids and handles, then manufacturing cost is reduced, but durability and reliability deteriorate
Solution Approach 1:
The container is divided into separate functional components: a base portion, a lid portion with hinge connection, and an integrally formed handle portion. This segmentation allows each part to be optimized for its specific function while maintaining overall durability, resolving the contradiction between manufacturing simplicity and reliability.
Solution Approach 2:
The handle is integrally formed with the base portion as a single piece, eliminating separate handle components that could detach or break. This merging of the handle and base into one robust structure significantly improves durability while actually simplifying manufacturing by reducing the number of separate parts to assemble.
2Ease of operation
If conventional containers use protruding handles, then carrying functionality is improved, but structural strength and durability worsen
Solution Approach 1:
The handle is integrally formed with the base portion, creating a unified structure where the handle becomes an extension of the base itself rather than a separate attachment. This eliminates weak connection points and maintains structural integrity while preserving carrying functionality.
Solution Approach 2:
The handle portion is specifically designed with ergonomic characteristics and appropriate thickness only where needed for carrying, while the rest of the base maintains its full structural strength. This localized optimization allows carrying functionality without compromising overall structural integrity.
3Device complexity
If conventional containers use simple latches, then device complexity is reduced, but reliability of lid closure deteriorates
Solution Approach 1:
The latch mechanism is integrated into the hinge connection between the lid and base, combining the closing and latching functions into a single mechanical assembly. This integration maintains simplicity while improving reliability, as the hinge structure itself provides the latching action without requiring separate complex latch components.
4Device complexity
If conventional containers lack sealing mechanisms, then device complexity is reduced, but water resistance and protection capability worsen
Solution Approach 1:
A flexible gasket is introduced between the lid and base portions to create a water-resistant seal. The gasket's flexibility allows it to conform to the mating surfaces and maintain an effective seal while accommodating minor manufacturing variations and thermal expansion, providing water resistance without excessive complexity.

AI summary
An insulating container having a base and a lid is provided. The lid may be rotatable about a hinge from a closed configuration to an open configuration and may be secured, via one or more latching devices, in the closed configuration. In some examples, the insulating container further includes a strap assembly with a convertible shoulder strap and handle that can convert between a handle configuration and a shoulder strap configuration. In some examples, the insulating container further includes a removable strap assembly with a clip over button interface that includes an outer pivot post located on the lateral sidewalls of the base and a pivot clip attached to the strap with the pivot clip sliding over the outer pivot post.
