Solution Overview
Problem
Power over Ethernet networks face challenges in reducing energy consumption for terminal devices, as they are typically assumed to be in continuous operation, leading to unnecessary energy usage even when devices are not in use.
Innovation Solution
Integration of a switching element within the connection unit of a patch cable, controlled via the network, allows for the interruption of power supply to terminal devices based on user presence, location, or time, reducing energy consumption by switching to a state with reduced energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal devices are continuously supplied with energy from the network, then device functionality is maintained, but energy consumption increases
Solution Approach 1:
The patent implements dynamic power management by integrating a switching element that can change the power supply state based on usage conditions. The connection unit monitors device activity and dynamically switches between power-on and power-off states, allowing the system to adapt its energy consumption to actual operational needs while maintaining device functionality when required.
Solution Approach 2:
The connection unit incorporates autonomous control capabilities to monitor device usage patterns and automatically manage power supply without requiring manual intervention. The system can detect when devices are in use or idle and self-regulate the power flow accordingly, reducing energy consumption during non-usage periods while ensuring power availability when needed.
2Extent of automation
If switching elements are integrated into connection units, then energy control capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the switching element, control logic, and connection unit functions into a single integrated component. By merging these previously separate functions into one unified device, the system gains automated energy control capability without proportionally increasing overall system complexity. The integrated design allows the switching functionality to be embedded within the existing connection infrastructure.

AI summary
The connection unit is intended for connecting terminals (T) to networks (LAN) that provide electric energy (E) to the terminals (T) connected thereto. The connection unit (AE) is configured for generating electric energy for the connection unit (AE) from the energy (E) provided, and has a switching element (SE) for separating the supply of energy for the terminals (T), wherein the switching element (SE) is controlled via the network (LAN). It is advantageous that the energy supply of the terminals (T) can be separated or switched on via the network (LAN) by means of the switching elements (SE), for example as a function of the presence or the location of users of terminals (T). Since the separations of the energy supply to the terminals may be carried out over longer periods of time, such as during the night, the energy consumption of the terminals (T) or of the networks (LAN) providing the electric energy to the terminals (T) can be reduced significantly.
