Method for transmitting a data set from an operating device to a drinks preparation machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinks preparation machines require cumbersome pairing methods or password communication for data transmission, such as user recipes, which complicates user operation and may lead to unauthorized access.
Innovation Solution
A method involving an operating device, a drinks preparation machine, and a coordination server, where the machine address is transmitted to the operating device, and the data set is stored and forwarded to the drinks preparation machine through the server, allowing indirect data transmission without direct communication, enhancing security and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct communication between operating device and drinks preparation machine is established for data transmission, then data transmission can be performed, but pairing complexity and security risks increase
Solution Approach 1:
A server acts as an intermediary between the operating device and the drinks preparation machine. The server receives the machine address from the operating device, stores the data set, and forwards it to the target machine, eliminating the need for direct pairing between the operating device and the machine.
Solution Approach 2:
The pairing process is extracted from the direct communication path between operating device and drinks preparation machine. The server takes over the pairing function by receiving machine addresses and establishing connections independently of the user's direct interaction.
2Ease of operation
If direct communication between operating device and drinks preparation machine is established, then data transmission is possible, but unauthorized access risk increases
Solution Approach 1:
The server serves as a security intermediary that verifies machine addresses and controls data transmission. It validates whether the target machine exists and is accessible before forwarding data, preventing unauthorized direct access attempts.
Solution Approach 2:
The server performs preliminary verification of the machine address and connection availability before allowing data transmission. This preliminary check ensures that only authorized transmissions to valid machines are permitted.
3Ease of operation
If indirect transmission through server is used, then security and ease of operation improve, but transmission time may increase
Solution Approach 1:
The server stores machine addresses and connection information in advance, allowing it to quickly forward data sets without performing complex routing or verification during the actual transmission moment.
Solution Approach 2:
The server maintains copies of machine address information and connection parameters, enabling rapid data forwarding without requiring real-time discovery or verification of the target machine's identity.

AI summary
A method for transmitting a data set from an operating device to a drinks preparation machine includes by the operating device: registering an input or a selection, which specifies the data set; by the drinks preparation machine, triggered by the user: transmitting a machine address of the drinks preparation machine to the operating device (4); by the operating device: receiving the machine address and transmitting the data set and the machine address to a coordination server; by the coordination server: storing the machine address and, assigned thereto, the data set; by the coordination server: transmitting this data set to the drinks preparation machine; by the drinks preparation machine: storing the data set and/or executing an action according to the data set.
