Insulating Container Dual-Seal Lid for Easy Leak Resistance

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing insulating containers with waterproof zippers are difficult to use due to the significant strength or gripping power required to close them, necessitating a less cumbersome yet leak-resistant solution.

Innovation Solution

The insulating container employs a dual-contact seal configuration with a first engagement region on the housing and a second engagement region on the lid, featuring a shelf portion, gasket, angled surfaces, and a gasket channel to create multiple points of interference and ensure a robust seal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If waterproof zippers are used to provide leak resistance, then reliability is improved, but ease of operation deteriorates due to significant strength or gripping power required to close them

Engineering Contradiction:

Improveleak resistanceVSAvoidgripping power required

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The sealing mechanism is segmented into two distinct parts: a first seal portion and a second seal portion. Each seal portion engages with its corresponding engagement region independently, distributing the sealing force across multiple contact points rather than requiring concentrated gripping force at a single zipper mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first and second seal portions act as intermediary elements between the first and second engagement regions. These seal portions create interference fits that distribute the sealing force across multiple contact points (first contact point and second contact point), eliminating the need for high gripping force while maintaining leak resistance.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a simple seal configuration is used, then ease of operation is improved, but reliability deteriorates due to potential leakage

Engineering Contradiction:

Improveoperational simplicityVSAvoidleak prevention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The sealing system is divided into two separate seal portions, each engaging with its own engagement region. This segmentation creates multiple independent sealing paths, ensuring that if one seal is compromised, the other maintains leak prevention while keeping each individual seal simple in design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sealing mechanism extends into multiple dimensional aspects: radial interference (first seal portion with first engagement region) and axial interference (second seal portion with second engagement region). This multi-dimensional sealing approach enhances reliability without complicating the operational simplicity of each individual seal component.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

Various embodiments of an insulating container that includes a lid configured for engagement with a housing for water leak protection. The housing and lid each respectively define a first angled surface and a second angled surface. When coupled, the first and second angled surfaces collectively define a shell interference that seals the container to prevent immediate leakage of fluid. Further, the insulating container includes a gasket that contacts a shelf portion of the housing, collectively defining a gasket interference that further seals the insulating container to prevent immediate leak-age.
