Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the drink is cooled by placing it in a refrigerator using traditional thermal conduction, then the cooling process is simple and requires no additional devices, but the cooling time is too long (one hour or more)
Solution Approach 1:
The patent applies the dynamics principle by introducing a rotating mechanism that continuously rotates the beverage container during cooling. This dynamic motion causes the beverage to circulate and contact different portions of the container wall, significantly enhancing heat transfer efficiency and reducing cooling time from over an hour to just a few minutes.
Solution Approach 2:
The patent utilizes fluid dynamics by causing the beverage to flow and circulate within the container through rotation. This hydraulic motion creates continuous convection currents that replace the poor thermal conduction with efficient convective heat transfer, rapidly cooling the entire volume of the beverage.
2Productivity
If the cooling container is rotated to accelerate heat conduction and convection, then the cooling speed increases dramatically, but the device structure becomes more complex
Solution Approach 1:
The rotating mechanism serves multiple functions: it rotates the beverage container to enhance heat transfer, provides structural support for the container, and integrates with the cooling chamber design. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity despite the added rotational capability.
Solution Approach 2:
The patent merges the rotating mechanism with the container support structure and cooling chamber design. The rotation shaft and support elements are integrated into a unified structure that performs both mechanical support and rotational drive functions, simplifying the overall device architecture while maintaining high cooling efficiency.
3Temperature
If a refrigeration unit with pump body and coolant circulation is added, then the cooling capability is enhanced, but the device size and complexity increase
Solution Approach 1:
The patent extracts the coolant circulation function from a separate, bulky refrigeration system and integrates it directly into the cooling chamber. The coolant channels are built into the chamber structure itself, eliminating the need for external pump bodies and large refrigeration units, thereby enhancing cooling capability while minimizing device volume.
Solution Approach 2:
The coolant circulation channels are nested within the cooling chamber structure. The refrigeration unit components are positioned inside or integrated with the chamber walls, creating a compact nested arrangement that maximizes cooling performance within a minimal volume.

AI summary
A fast cooling device comprises a rotating device for installing and rotating the cooling container, and the rotating device is placed in the cooling space; the rotating device drives the cooling container to rotate in the cooling space. Placing the cooling container which contains liquid in the cooling space and rotating it can cause the liquid flow in the container, thereby accelerating heat conduction and convection, so that all the liquid in the cooling container can be quickly cooled down. The cooling down time reduce from one hour or more by using the existing refrigerators to a few minutes to ten minutes. Moreover, the entire device is relatively simple in structure and low production cost. It can also achieve miniaturization design and use DC power supply, so that user can quickly cool drinks conveniently anywhere.
