Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If cooling fins and heat dissipation fan are used to dissipate heat from refrigeration module, then heat dissipation is achieved, but heat dissipation efficiency is low and cost is high
Solution Approach 1:
The patent extracts the heat dissipation function from the traditional air-cooling system (cooling fins and fan) and implements a separate water cooling circuit system. The water cooling circuit independently circulates cooling water through heat exchange components to dissipate heat from the refrigeration module, separating the heat dissipation pathway from the coffee brewing pathway and achieving more efficient heat removal.
Solution Approach 2:
The patent introduces cooling water as an intermediary medium to transfer heat away from the refrigeration module. The cooling water circulates through the water cooling circuit, absorbing heat from heat exchange components (such as heat dissipation plates) and transporting it to a heat dissipation tank or external cooling system, thereby efficiently removing heat without requiring large air-cooling components.
2Loss of energy
If cooling fins and heat dissipation fan are used, then heat dissipation is achieved, but device size is large
Solution Approach 1:
The patent employs a hydraulic cooling system where cooling water circulates through closed-loop pipes and heat exchange components. This liquid-based heat transfer system is more space-efficient compared to air-cooling systems with large cooling fins and fans, as water has higher specific heat capacity and thermal conductivity, allowing for compact heat exchanger design that dissipates the same amount of heat in a smaller volume.
3Loss of energy
If cooling fins and heat dissipation fan are used, then heat dissipation is achieved, but noise is loud
Solution Approach 1:
The patent replaces the mechanical air-cooling system (which requires a rotating fan to force air flow over cooling fins) with a hydraulic cooling system. The water circulation is driven by a pump, and heat dissipation occurs through thermal conduction and convection in the water-cooled components and heat dissipation tank, eliminating the need for high-speed rotating fans and significantly reducing operational noise while maintaining effective heat dissipation.
4Temperature
If refrigeration module is used to cool drinking water, then cold brew is achieved, but refrigeration efficiency is affected due to heat accumulation
Solution Approach 1:
The patent implements a continuous water circulation system where cooling water constantly flows through the water cooling circuit, continuously absorbing heat from the refrigeration module's heat exchange components. This continuous flow prevents heat accumulation in the refrigeration system, maintaining sustained refrigeration efficiency and ensuring drinking water remains at the desired low temperature throughout the brewing process.
