Double-walled vessel for storing a potable liquid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-walled vessels require a specific shape for the inner container to securely attach the outer container, limiting versatility and ease of use.
Innovation Solution
A double-walled container design featuring an outer container with releasably connectable shells that can be easily attached to an inner container of any shape, using a friction fit and locking lever for secure positioning without the need for precise matching shapes, allowing for easy detachment and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer container is designed to attach to the inner container with a specific shape (e.g., hollow cylindrical or conical), then the attachment is secure and form-fitting, but the versatility is limited as the inner container must have a specific shape
Solution Approach 1:
The outer container is divided into at least two separate shells that can be releasably connected to each other. This segmentation allows the outer container to adapt to different inner container shapes while maintaining secure attachment through the combination of multiple flexible components rather than a single rigid structure.
Solution Approach 2:
The outer container with releasably connectable shells is designed to be universally compatible with inner containers of various shapes. The shells can be connected and disconnected to accommodate different geometries, making the outer container multi-functional and adaptable to diverse inner container designs.
2Reliability
If the outer container is permanently attached to the inner container, then the insulation is maintained, but the cleaning access is limited
Solution Approach 1:
The outer container shells are designed with releasable connections that allow dynamic switching between attached and detached states. When attached, the shells provide continuous insulation; when detached, they provide full access to the inner container for cleaning. This dynamic design resolves the contradiction between maintaining insulation and enabling cleaning access.
3Strength
If the outer container is made as a single rigid piece, then the structural strength is high, but the adaptability to different inner container shapes is reduced
Solution Approach 1:
Dividing the outer container into multiple shells maintains structural integrity through proper connection mechanisms while enabling adaptability to different inner container shapes. Each shell can be individually positioned and connected to conform to various geometries without compromising overall strength.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the use of double-walled vessels with inner containers of various shapes, enhancing usability and allowing for thorough cleaning, while maintaining effective insulation and temperature retention.
Implementation Method 1
the at least two shells can be connected to one another in a detachable manner, in particular by means of a friction fit
Implementation Method 2
insulation can be increased compared to single-walled vessels, so that hot drinks stay hot longer and cold drinks stay cold longer

AI summary
The invention relates to a double-walled vessel for storing a potable liquid, particularly a hot drink such as coffee, comprising an inner container (12) that encloses a cavity (34) for receiving the liquid and that forms at least one contact surface (46), and an outer container (14) which comprises at least two shells (16, 18) that are detachably interconnectable, wherein the outer container (14) at least partially encloses the inner container (12) when in the connected state, and is supported against the contact surface (46) when in the connected state.
