Solution Overview
Problem
Existing beverage containers fail to effectively maintain the temperature of cold or frozen beverages, leading to rapid temperature increase and uncomfortable surface conditions due to condensation.
Innovation Solution
A container design featuring a double-walled structure with insulating features, including annular bands and spacers between the inner and outer sidewalls, which create pockets to minimize heat transfer and maintain desired temperature and surface conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-walled container structure is used, then the device complexity is reduced, but the temperature maintenance capability deteriorates
Solution Approach 1:
The container is divided into two separate walls (inner sidewall and outer sleeve) with an insulating cavity between them. This segmentation creates a thermal barrier that prevents heat transfer while maintaining a relatively simple overall container structure.
Solution Approach 2:
The outer sleeve is attached to the inner sidewall to form a nested double-walled structure. The insulating cavity is formed by nesting the outer sleeve around the inner sidewall, creating insulation without adding significant external complexity.
2Ease of manufacture
If no insulating features are added, then the manufacturing cost and complexity are reduced, but the temperature maintenance duration deteriorates
Solution Approach 1:
The insulating cavity is created by segmenting the container wall into inner and outer layers, providing effective insulation that extends temperature maintenance duration without requiring complex manufacturing processes.
Solution Approach 2:
The insulating cavity acts as an intermediary layer between the cold beverage and the external environment. This intermediate space prevents direct heat transfer, extending the duration of temperature maintenance while keeping the manufacturing process simple.
3Temperature
If a double-walled structure with insulating features is used, then the temperature maintenance capability is improved, but the device complexity increases
Solution Approach 1:
The container is segmented into inner sidewall and outer sleeve components that can be manufactured separately and then assembled, maintaining manufacturing simplicity while achieving effective insulation through the created cavity.
Solution Approach 2:
The outer sleeve is nested around the inner sidewall to form the insulating structure. This nesting approach creates the double-walled insulation system without significantly increasing the overall container complexity or footprint.
4Ease of operation
If insulating features are added to prevent condensation, then the surface comfort is improved, but the manufacturing complexity increases
Solution Approach 1:
The container wall is segmented into inner and outer layers with an insulating cavity, preventing condensation on the outer surface and improving grip comfort without requiring complex manufacturing processes.
Solution Approach 2:
The insulating cavity serves as an intermediary thermal barrier that prevents moisture condensation on the outer sleeve, improving surface comfort and gripability while maintaining relatively simple manufacturing procedures.
