Innovation Solution
A portable electric pumping coffee machine with a drainage module, extraction module, and heating module, featuring a water pump, one-way valve, and extraction containers with filtering layers and blades, allowing for efficient extraction of both coffee capsules and powder, and heated water control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a professional coffee machine is used to brew capsule coffee, then the coffee taste is preserved fresh, but the machine is bulky and cannot be carried outdoors
Solution Approach 1:
The coffee machine is divided into separate functional modules: a removable capsule holder, a water reservoir, a brewing chamber, and a base unit. This segmentation allows users to carry only the essential components outdoors while maintaining capsule brewing capability, resolving the contradiction between preserving coffee quality and ensuring portability.
Solution Approach 2:
The machine base is designed to accommodate multiple types of coffee capsules and can also brew coffee powder, making it a universal brewing device. This multi-functionality ensures that users can maintain their preferred coffee brewing methods across different locations without requiring multiple specialized devices, thus preserving coffee quality while improving portability.
2Weight of moving object
If a portable coffee machine is used, then the machine is easy to carry, but the extraction efficiency of coffee capsules and powder is poor
Solution Approach 1:
The machine incorporates an adjustable extraction mechanism that can dynamically adapt to different capsule types and coffee powder configurations. The extraction pressure and water flow rate are可调 to optimize brewing parameters for each specific medium, ensuring high extraction efficiency despite the compact portable design.
Solution Approach 2:
A miniaturized high-pressure water pump system is integrated into the portable machine, utilizing pneumatic-hydraulic principles to generate sufficient extraction pressure for both capsules and coffee powder. This advanced fluid control system maintains extraction efficiency comparable to larger machines while keeping the overall device portable.
3Device complexity
If a portable coffee machine without water pump and drainage assembly is used, then the machine is simpler, but the water flow speed is uncontrollable and water leakage occurs
Solution Approach 1:
The machine incorporates electronically controlled valves and flow regulators that dynamically adjust water flow parameters based on the selected brewing mode. This parameter control system ensures precise water flow management for both capsules and coffee powder, preventing leakage while maintaining reliability without significantly increasing structural complexity.
4Weight of moving object
If a portable coffee machine without heating module is used, then the machine is lighter, but hot water cannot be added to the coffee machine
Solution Approach 1:
The machine includes a pre-heating water reservoir and a rapid heating element that activates before the brewing cycle begins. This preliminary heating action ensures that water is already at the required temperature when brewing starts, eliminating the need for heavy continuous heating systems while maintaining versatility for both capsules and coffee powder.
