Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing PoE capable devices lack a convenient and safe method for users to easily regulate power levels, which can lead to safety hazards or malfunctions if power levels are not compatible, and current methods for managing policies are cumbersome and inconvenient.
Innovation Solution
A manual information input module is introduced for PoE capable devices, allowing users to manage power modes through a simple interface with switches and LEDs, enabling easy selection of power modes such as high power (HP), standard power (SP), power sourcing equipment (PSE), and powered device (PD) modes, using internal switches like FETs or transistors, and indicating current modes with LED lights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual information input module with switches is added to PoE devices, then ease of operation is improved, but device complexity increases
Solution Approach 1:
A manual information input module serves as an intermediary between the user and the PoE device's power management system. The module includes physical switches (HP switch, SP switch, PSE switch, PD switch) that users can directly manipulate to change power modes without navigating complex menus or configurations. This intermediary layer simplifies user interaction while the device's processing unit handles the complexity of power mode transitions internally.
Solution Approach 2:
The PoE device is enhanced with self-service capabilities through the manual information input module, allowing users to independently regulate power modes without requiring external configuration tools or complex setup procedures. The device automatically processes switch inputs and transitions between power modes (HP, SP, PSE, PD) based on user selections, enabling users to manage power settings autonomously.
2Adaptability or versatility
If power levels are not regulated properly in PoE devices, then adaptability is improved, but safety hazards increase
Solution Approach 1:
The system performs preliminary actions by pre-configuring distinct power modes (HP, SP, PSE, PD) with predetermined power delivery parameters. Before power is actually delivered, the user selects the appropriate mode through the manual input module, and the processing unit validates and prepares the power delivery settings in advance. This preliminary configuration ensures that power levels are appropriate for the connected device before energy transfer begins, preventing safety hazards.
Solution Approach 2:
The manual information input module provides feedback mechanisms through LED indicators that display the current power mode and status of the PoE device. This visual feedback allows users to verify that the correct power mode is selected and confirms that the device has properly recognized and configured the power delivery parameters. The feedback loop ensures users can monitor power level compatibility and make adjustments if needed, preventing unsafe power delivery.

AI summary
The present invention discloses methods and systems for managing a power over Ethernet (PoE) capable device through a manual information input module. Information is obtained through the manual information input module, and a current power mode is determined. Based on the information, a power mode is reset or applied. If it is determined to apply a power mode, internal switches are opened or closed and the device supplies or receives power over Ethernet according to the power mode.
