Method for operating a system with at least two identically designed domestic appliances and system with at least two identically designed domestic appliances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of household appliances, such as food processors and cleaning devices, receive unhelpful correction suggestions due to the lack of real-time comparison with identical appliances, leading to ineffective support during work steps.
Innovation Solution
A method where the current work step of one household appliance is compared with another identical appliance in real-time, allowing for the exchange of data communication addresses and enabling immediate support through app-supported networking, ensuring identical work steps are executed with identical parameters, and allowing users to connect for mutual assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If correction suggestions are transmitted to users based on stored reference parameters, then users receive automated support, but the reliability of these suggestions is low because there is no real-time comparison with identical appliances performing the same work steps
Solution Approach 1:
The system implements feedback by collecting actual operating data from multiple identical household appliances performing the same work steps and using this real-time information to generate and transmit corrected suggestions to users. The control device receives actual data from sensors, compares it with reference parameters, and provides feedback in the form of corrected suggestions based on current operational conditions rather than static stored data.
Solution Approach 2:
The system performs preliminary actions by pre-storing reference parameters for work steps and pre-establishing communication channels between appliances and the control device. This allows the system to quickly compare actual operating data with reference data and transmit corrected suggestions without delay when deviations are detected, ensuring timely support while maintaining reliability.
2Ease of operation
If real-time data communication is established between multiple household appliances, then users can exchange experiences and provide mutual support, but the system complexity increases due to networking requirements
Solution Approach 1:
The control device serves as an intermediary that mediates data communication between multiple household appliances. Instead of requiring direct peer-to-peer networking between appliances, the control device receives actual operating data from various appliances, processes this information, and transmits corrected suggestions back to users. This intermediary approach simplifies the overall system architecture while enabling real-time collaborative support.
Solution Approach 2:
The control device performs multiple functions: it acts as a data collection point from various appliances, a processing center for comparing actual data with reference parameters, a communication hub for transmitting corrected suggestions, and a coordination point for establishing data communication between appliances. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity.
3Reliability
If household appliances transmit actual operating data and establish communication connections in real-time, then accurate comparison and support are enabled, but energy consumption increases due to continuous data transmission
Solution Approach 1:
The system implements periodic action by transmitting actual operating data from household appliances to the control device at specific intervals or at key event points during work steps, rather than continuously. This allows for accurate comparison of work steps while reducing energy consumption associated with constant data transmission. The control device transmits corrected suggestions back to users based on these periodic data updates.

AI summary
Method for operating a system with at least two identically designed household appliances (1, 2), in particular at least two soil cultivation devices or at least two kitchen machines, wherein a first household appliance (1) performs a work activity with at least one predefined work step, wherein the work step is defined by a device parameter (3) and/or execution parameter to be applied for the execution of the work step.In order to enable a qualified exchange of experience between different users of identical household appliances (1, 2), it is proposed that the currently executed work step of the first household appliance (1) be compared with a simultaneously executed work step of at least one second household appliance (2), and wherein, if the work step of the first household appliance (1) matches the work step of the second household appliance (2), contact information (5) containing at least one data communication address (4) of the second household appliance (2) or of a second external terminal device (7) in communication with it is transmitted to the first household appliance (1) or to a first external terminal device (6) in communication with the first household appliance (1).
