Solution Overview
Problem
Current energy networks in industrial settings are either too expensive or inflexible, and there is a high need for safe and efficient switching operations, particularly regarding switching on and off, to manage power distribution effectively.
Innovation Solution
A connection box with an internal evaluation unit, electronic switch, and mechanical isolator is used, featuring a decentralized evaluation program that can identify devices, set up networks, determine energy consumption, and switch outputs independently, ensuring safe and inexpensive operations by handling administrative tasks locally and allowing for galvanic decoupling and wear monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If centralized control units and communication networks are used for energy distribution management, then power consumption can be centrally controlled and adapted, but system cost and complexity increase significantly
Solution Approach 1:
The patent divides the energy distribution system into autonomous connection boxes, each capable of independent decision-making. Instead of one centralized control unit managing all devices, each connection box evaluates its own power consumption needs and makes switching decisions locally, segmenting the control function across multiple independent units.
Solution Approach 2:
Each connection box is equipped with an integrated evaluation unit that autonomously evaluates power consumption requirements and makes switching decisions without external intervention. The system serves itself through decentralized intelligence, where each unit independently manages its own power distribution decisions.
2Reliability
If mechanical isolators are used for switching operations, then galvanic isolation is achieved, but wear and reliability issues occur due to frequent switching
Solution Approach 1:
The evaluation unit performs preliminary assessment of power consumption requirements before triggering any switching operation. By evaluating whether power consumption exceeds thresholds in advance, the system prevents unnecessary isolator actuation, thereby reducing wear and extending lifespan while maintaining galvanic isolation when truly needed.
Solution Approach 2:
The patent replaces frequent mechanical switching with electronic evaluation and control. The mechanical isolator is used only as a fallback for galvanic isolation when electronically switched off, rather than for routine switching operations. This substitution reduces mechanical wear while maintaining isolation reliability.
3Speed
If outputs are switched off without verifying actual power consumption, then switching speed is improved, but unnecessary isolator actuation causes wear
Solution Approach 1:
The evaluation unit performs preliminary measurement and evaluation of actual power consumption before initiating any isolator actuation. This preliminary action ensures that switching occurs only when genuinely necessary, preventing unnecessary wear while maintaining fast response when power consumption thresholds are actually exceeded.
4Loss of energy
If centralized monitoring and control is implemented, then power consumption can be optimized, but system cost increases
Solution Approach 1:
Each connection box independently evaluates and optimizes its own power consumption through integrated evaluation units. This self-service approach eliminates the need for expensive centralized monitoring infrastructure, achieving energy optimization through decentralized intelligence rather than costly central control systems.
Solution Approach 2:
The patent segments the monitoring and control function into independent connection boxes distributed throughout the system. Each unit independently optimizes local power consumption, replacing the need for a centralized monitoring system with multiple autonomous decision-making units, thereby reducing overall system cost.

AI summary
The aim of the invention is to improve the operational reliability and the operability of energy networks in an inexpensive manner. In particular, the reliability during an activation and deactivation under load and the measurement of the energy consumption even within complex topologies is to be improved. This is achieved by a method (2) for operating an energy network comprising multiple junction boxes (2, 2',... ), having the following steps: - opening the electronic switch (231) of a junction box (2) using an analysis unit (26) of the junction box (2); - waiting for a defined period of time (∆t); - measuring the potential at the output of the electronic switch using the analysis program and a corresponding voltage measuring device (232); - comparing the measured potential U with a specified value (URef); - setting a release parameter dependent on the measured potential (U) falling below the specified value (URef); and - opening the mechanical separator (233) dependent on the release parameter, and in particular by: - generating a priority level (Prio) for the provided deactivation process; - carrying out the deactivation process dependent on the priority level; and - increasing the content of a counter (Z) if the deactivation process is successful and the release parameter has not been set.
