Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a professional coffee machine is used to brew capsule coffee, then the coffee extraction quality is improved, but the device size becomes bulky and cannot be carried outdoors
Solution Approach 1:
The coffee machine is divided into detachable modules: a water tank module, a coffee capsule extraction module, and a handle module. This segmentation allows the device to be disassembled into compact components for easy carrying, while maintaining full brewing functionality when assembled.
Solution Approach 2:
The coffee capsule is inserted into the extraction module, which is then inserted into the water tank module. The nested structure allows compact storage and easy assembly/disassembly for portability while maintaining the complete brewing system.
2Weight of moving object
If coffee powder is brewed manually outdoors, then the device portability is improved, but the coffee extraction efficiency and taste quality deteriorate
Solution Approach 1:
The extraction module automatically performs the brewing process by injecting water into the coffee capsule under pressure. The system self-regulates water flow and extraction timing, eliminating the need for manual stirring or complex user operations while maintaining high extraction efficiency.
3Device complexity
If a portable coffee machine without water pump is used, then the device complexity is reduced, but the water flow control precision deteriorates
Solution Approach 1:
A small water pump is integrated into the portable coffee machine to provide controlled water flow to the coffee capsule. The pump enables precise regulation of water pressure and flow rate, ensuring optimal extraction while maintaining compact device dimensions.
4Volume of moving object
If a portable coffee machine without heating module is used, then the device size is reduced, but the brewing temperature control capability deteriorates
Solution Approach 1:
A compact heating element is integrated into the water tank module, allowing precise control of water temperature before injection. The heating module includes temperature sensing and control circuitry to maintain optimal brewing temperature despite the reduced device size.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient, high-quality coffee brewing anywhere by efficiently extracting coffee from capsules and powder with controlled water flow and heating, ensuring rich aroma and preventing water leakage.
Implementation Method 1
the water pump is connected to the heating cup through the water pipe... The water pump pressurizes the water to pass through the drain sleeve and the diversion sleeve
Implementation Method 2
The outer surrounding wall or bottom of the heating cup is equipped with a heating member which is arranged to heat water in the heating cup
Implementation Method 3
The water pump pressurizes the water to pass through the drain sleeve and the diversion sleeve, so as to act on a coffee capsule for achieving brewing
