Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an electric heater is used for heating, then the heating function is realized, but the floor space is large and the heating speed is slow
Solution Approach 1:
The patent changes the heating method from conventional electric heater to ultrasonic vibration heating. The ultrasonic heating element generates high-frequency vibrations that directly convert mechanical energy to thermal energy, dramatically increasing heating speed while reducing the required floor space to 0.06m².
Solution Approach 2:
The patent replaces the traditional thermal conduction heating system with an ultrasonic mechanical vibration system. The ultrasonic heating element uses piezoelectric or magnetostrictive effects to generate mechanical vibrations at ultrasonic frequencies, which are then converted to heat through cavitation and friction in the liquid, achieving faster and more compact heating.
2Extent of automation
If no high-voltage water pump is used, then the device is simpler, but automatic coffee extraction cannot be achieved
Solution Approach 1:
The patent implements automatic coffee extraction through a control system that automatically activates the high-voltage water pump when a button is pressed. The system self-regulates the water flow, heating, and extraction processes without requiring manual intervention, achieving full automation while keeping the device relatively simple through integrated control circuitry.
Solution Approach 2:
The patent introduces a control system as an intermediary between the user and the various components (water pump, heater, extraction mechanism). This control system coordinates all operations automatically, enabling complex automated extraction functionality while maintaining simplicity in the user interface and overall device architecture.
3Productivity
If conventional heating and extraction methods are used, then the device is simpler, but the brewing efficiency and speed are reduced
Solution Approach 1:
The patent uses ultrasonic vibration to preheat and pre-mix the water and coffee grounds before the actual extraction process. The ultrasonic heating element rapidly brings water to the optimal brewing temperature, and the high-voltage water pump pre-pressurizes the system, significantly reducing the time required for complete brewing while maintaining efficiency.
Solution Approach 2:
The patent employs periodic ultrasonic vibrations and pulsating water flow from the high-voltage pump to enhance extraction efficiency. The ultrasonic field oscillates at high frequency, creating periodic cavitation bubbles that collapse and intensify mixing, while the pump delivers water in controlled pulses, maximizing contact between water and coffee grounds within a short time frame.
