Problem

Existing methods for managing power transmission in decentralized network components via Ethernet cables, such as PoE, face challenges in efficiently determining and utilizing available energy, particularly for devices with varying power consumption and functionalities, leading to potential device damage and inefficient resource allocation.

Innovation Solution

A method where decentralized network components simulate different power classes to determine supported classes by the central network component, allowing activation of functionalities only if sufficient energy is available, independent of subscriber line resistance, and utilizing a standardized test phase for efficient power management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If full power is provided to each terminal device, then device functionality is improved, but system power consumption increases and power allocation efficiency deteriorates

Engineering Contradiction:
Improvedevice functionalityVSAvoidsystem power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic power class assignment by changing the power parameters provided to different terminal devices based on their actual needs. The central power supply unit determines appropriate power classes for each device and adjusts power delivery accordingly, rather than providing full power to all devices. This resolves the contradiction by enabling full functionality for devices that need it while reducing power consumption for devices with lower requirements.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If power is provided to all terminal devices, then device operation is ensured, but power allocation efficiency and resource utilization deteriorate

Engineering Contradiction:
Improvedevice operationVSAvoidpower allocation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies local quality by providing different power levels to different terminal devices based on their individual characteristics and requirements. Each device receives a customized power allocation determined by the central power supply unit, which assesses device needs and assigns appropriate power classes. This ensures reliable operation for all devices while optimizing overall power allocation efficiency.

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If minimal power is provided during detection phase, then device safety is improved, but power availability for functionality activation deteriorates

Engineering Contradiction:
Improvedevice damage preventionVSAvoidpower availability
Core Design Contradiction:
Object-affected harmful factorsVSUse of energy by moving object

Solution Approach 1:

The patent implements preliminary action by conducting a detection and classification phase before full power delivery. During this initial phase, minimal power is provided to safely detect device presence and determine power class requirements. Once device characteristics are known, the system transitions to providing appropriate power levels, thus preventing device damage while ensuring sufficient power availability for required functionalities.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If power classes are strictly enforced, then power management control is improved, but device functionality and energy utilization deteriorate

Engineering Contradiction:
Improvepower management controlVSAvoiddevice functionality
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making power class assignment flexible rather than rigid. While the system uses power classes as a framework for power management control, it dynamically adjusts power allocation based on actual device requirements, available power resources, and functional needs. This dynamic approach maintains good power management control while enabling adaptable device functionality.

Inventive Principle:
Principle #15Dynamics
