Insulated Double-Wall Container with Vacuum Cavity and Dimple Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drinkware containers fail to effectively maintain temperature and reduce noise when placed on a surface, as they lack advanced insulative properties and sound-damping mechanisms.
Innovation Solution
The development of an insulating container with a sealed vacuum cavity formed between a first inner wall and a second outer wall, incorporating a dimple sealed with resin and covered by a disc or cap, which also includes sound-damping features such as weight components or ripple shapes to minimize noise when placed on a surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional single-wall container structure is used, then the device complexity is low, but the insulative properties are insufficient to maintain liquid temperature
Solution Approach 1:
The container is divided into two separate walls (first inner wall and second outer wall) with a vacuum cavity between them, creating a double-wall structure that provides thermal insulation while maintaining liquid temperature
Solution Approach 2:
A vacuum cavity is introduced as an intermediary space between the inner and outer walls, acting as a thermal barrier that prevents heat transfer and maintains liquid temperature without requiring complex active insulation systems
2Object-affected harmful factors
If a conventional container without sound-damping features is used, then the manufacturing process is simple, but noise is not reduced when placed on a surface
Solution Approach 1:
A dimple is formed in the bottom portion of the container during manufacturing, and weight components or ripple shapes are incorporated to provide sound-damping and noise reduction capabilities before the container is used
Solution Approach 2:
The container incorporates multiple materials and structures including the vacuum cavity, resin sealing, metal walls, and sound-damping components (weight components or ripple shapes) to achieve both insulation and noise reduction functions
3Reliability
If the vacuum cavity is not sealed properly, then the manufacturing process is simpler, but the insulative properties are compromised
Solution Approach 1:
Resin is used as an intermediary sealing material to seal the opening of the dimple and maintain the vacuum cavity integrity, ensuring reliable thermal insulation without requiring complex mechanical sealing mechanisms
Solution Approach 2:
The resin forms a flexible seal around the dimple opening that can accommodate manufacturing tolerances and thermal expansion, maintaining vacuum integrity while keeping the sealing mechanism simple

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The container maintains temperature through the insulated double-wall structure and reduces noise through sound-damping mechanisms, providing a more efficient and user-friendly beverage storage solution.

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 hole extending into the second outer wall. The hole can be sealed by a resin, and the circular base can be covered by disc formed of the material. Alternatively, a cap can cover the dimple, and a weld can connect the cap to the second outer wall. The container can also include a sealed vacuum cavity forming an insulated double-wall structure between the first inner wall and the second outer wall.
