Solution Overview
Problem
Complex electrical and data connections in hot beverage preparation machines increase safety risks, material costs, and production difficulties, while also affecting the leak-proofing of the water container.
Innovation Solution
A control unit that sequentially activates a temperature sensor and a pump via a common connector, utilizing switches and a diode unit to simplify the electrical connection and enable controlled operation, allowing for separate timing of sensor and pump activation during different process steps, thereby reducing the need for simultaneous operation and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connectors are used for the temperature sensor and pump, then reliable data and power transfer is achieved, but device complexity and production difficulty increase
Solution Approach 1:
The patent combines the data transfer and power supply functions into a single connector interface between the control unit and water container. This single connector simultaneously establishes electrical connections for both the temperature sensor data transmission and the pump power supply, eliminating the need for separate connectors and reducing overall system complexity while maintaining reliable data and power transfer
Solution Approach 2:
The connector is designed with multi-functionality to handle both data transfer and power supply tasks through the same physical interface. This universal connector serves multiple purposes: transmitting temperature sensor data, providing power to the pump, and establishing control signals, thereby reducing the number of components needed without compromising functional reliability
2Reliability
If multiple connectors are used for control unit connections, then reliable electrical connection is achieved, but production cost and material usage increase
Solution Approach 1:
The patent merges multiple electrical connection functions into a single connector assembly that provides both data and power pathways simultaneously. This reduces the total number of connectors required from multiple separate units to one integrated connector, thereby lowering material costs, reducing assembly steps, and simplifying production processes while maintaining reliable electrical connections for all components
3Adaptability or versatility
If complex electrical connection structures are used, then complete control functionality is achieved, but leak-proofing of the water container is adversely affected
Solution Approach 1:
The patent combines electrical connection functions into a single integrated connector that seals against the water container at one location rather than multiple separate connection points. This single sealed interface maintains the leak-proof integrity of the water container while still providing complete control functionality for the temperature sensor, pump, and heater through the unified connector design
