Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional systems use device IDs for controlling and monitoring electrical devices, then device identification is achieved, but system complexity increases and user operation becomes difficult
Solution Approach 1:
The system automatically detects parameter changes caused by plugging/unplugging devices or switching operations, and autonomously assigns logical addresses without requiring user intervention. The power supply module monitors its own supply circuits and performs self-configuration, eliminating the need for complex manual device ID entry and simplifying user operation while maintaining device identification capabilities
Solution Approach 2:
The invention uses detectable parameter changes (internal resistance, current consumption) that occur naturally during device plugging/unplugging or switching operations as identification signals. By monitoring these inherent parameter variations, the system assigns logical addresses automatically without requiring complex device ID input from users, thus reducing operational complexity while preserving device identification functionality
2Productivity
If manual device ID assignment is used, then device identification is achieved, but assignment complexity and time consumption increase
Solution Approach 1:
The system performs preliminary detection of parameter changes immediately when a device is plugged in or switched on. By monitoring supply circuit parameters in real-time and automatically assigning logical addresses at the moment of device connection, the system eliminates subsequent manual configuration steps, significantly improving assignment speed while reducing the complexity of the assignment process itself
3Measurement precision
If logical assignment is performed via device ID selection, then precise device identification is achieved, but the process becomes complex and time-consuming
Solution Approach 1:
The power supply module autonomously monitors parameter changes in its supply circuits and automatically assigns logical addresses without requiring user input or device ID selection. This self-configuration process maintains precise device identification through unique parameter change detection while eliminating time-consuming manual assignment procedures
Solution Approach 2:
The invention replaces the mechanical interaction of manual device ID entry and selection with automated electronic parameter change detection. By substituting user-based mechanical input with electronic monitoring of inherent parameter variations, the system achieves precise device identification instantly without the time loss associated with manual device ID assignment processes

AI summary
The invention relates to a method and a device for controlling or monitoring an electrical appliance (7) that can be inserted into a power outlet (6) in order to be supplied with power, said outlet being connected to a power supply terminal (2) of a power supply module (1) by means of a power supply circuit (5). First, an identification (S1) of the power outlet (6) used for the electrical appliance (7) is carried out on the basis of a parameter change detected at the power supply terminal (2) of the power supply module (1) or on the basis of an identification signal transmitted from the power outlet (6) to the power supply connection (2) of the power supply module (1) via a signalling line (11) associated with the power supply circuit (5). A logical address of the identified power outlet (6) is then associated (S2) with the respective power supply terminal (2) of the power supply module (1). The electrical appliance (7) connected to the identified power outlet (6) is controlled or monitored (S3) on the basis of the associated logical address of the identified power outlet (6).
