Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation and direct-flow water outlet are used for coffee brewing, then the brewing process is simple to implement, but the brewing effect is seriously affected and requires very high skills
Solution Approach 1:
The patent replaces manual mechanical operation with an automatic rotation system. The cup holder rotates automatically to position the coffee cup under the water outlet, eliminating the need for manual positioning skills while ensuring consistent brewing results through automated control.
Solution Approach 2:
The system performs self-positioning through automatic rotation of the cup holder, allowing the brewing device to orient itself correctly without user intervention. The detection system automatically identifies cup positions and adjusts rotation accordingly, enabling the system to serve itself in the positioning task.
2Measurement precision
If electrical connection is used to drive cup holder rotation, then the rotation control is precise, but the structure becomes complex and less reliable
Solution Approach 1:
The patent replaces electrical connection with wireless communication technology. The control circuit in the base communicates wirelessly with the control circuit in the cup holder to transmit rotation control signals, eliminating physical electrical connections while maintaining precise control capability through wireless signal transmission.
Solution Approach 2:
The patent introduces wireless communication as an intermediary between the base control circuit and the cup holder control circuit. This intermediary enables signal transmission without direct electrical contact, reducing structural complexity and improving reliability while preserving control precision.
3Reliability
If wireless driving is implemented for cup holder rotation, then the structure is simplified and reliability improved, but power transmission to the rotating cup holder becomes challenging
Solution Approach 1:
The patent replaces wired power transmission with wireless power transmission technology. The base transmits power wirelessly to the cup holder, enabling the rotating component to receive power without physical electrical connections, thus simplifying the structure and improving reliability while solving the power transmission challenge.
