Double-Wall Vacuum-Sealed Insulating Container with Dimple Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinkware containers struggle to maintain temperature insulation effectively, particularly in designs that do not utilize advanced vacuum-sealed double-wall structures.
Innovation Solution
The development of an insulating container with a sealed vacuum cavity formed between a first inner wall and a second outer wall, featuring a dimple in the bottom portion that is sealed with resin and optionally covered by a disc or cap, to create an insulated double-wall structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a double-wall vacuumed formed construction is used, then temperature insulation is improved, but manufacturing complexity increases
Solution Approach 1:
The container is divided into separate inner and outer wall components that are formed individually and then assembled. The inner wall and outer wall are created as separate pieces with a vacuum space between them, allowing for simpler individual manufacturing processes while achieving the insulation benefits of a vacuum-sealed double-wall structure.
Solution Approach 2:
The inner wall is nested within the outer wall to create a vacuum insulation chamber. This nested configuration allows the vacuum-sealed double-wall structure to be formed by positioning one component inside another and sealing the space between them, simplifying the overall manufacturing process.
2Object-affected harmful factors
If a dimple is added to the bottom portion, then noise damping is improved, but manufacturing steps increase
Solution Approach 1:
The dimple is formed as an integral feature of the outer wall during the initial forming process, rather than being added as a separate step. The sealing material and cover are then applied to this pre-formed dimple structure, reducing the overall number of manufacturing steps while achieving noise damping.
Solution Approach 2:
The dimple structure is merged with the outer wall formation process, and the sealing and covering functions are combined into a single assembly operation. This integration reduces manufacturing complexity while maintaining the noise-damping functionality.

AI summary
An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The second outer wall can include a second end configured to support the container on a surface. The second outer wall can include a dimple, and the dimple can include a circular base and an inner portion converging to an opening extending into the second outer wall. The opening can be sealed by a resin, and the circular base can be covered by disc formed of the material. The outer wall and the inner wall can be constructed from different materials such that the outer wall is harder and resists indentation, and the inner wall reduces the overall weight of the container.
