PDU Wireless Module with LED Status Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identifying a specific Power Distribution Unit (PDU) among multiple units in a datacenter using wireless communication is challenging due to the lack of selective discoverability and clear connectivity status in existing systems, particularly with Bluetooth technology, which can lead to connecting with unintended PDUs.
Innovation Solution
Incorporating a wireless communications module with a near-field communications (NFC) or Bluetooth interface in PDUs, featuring a 'discoverability' pushbutton and LED indicators to facilitate controlled discoverability and ensure connection with the intended PDU, allowing users to initiate limited discoverability and confirm connectivity status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth wireless communication is used for PDU discovery and connection, then user interaction with PDU is enabled, but difficulty in identifying and connecting to the specific intended PDU among multiple units increases
Solution Approach 1:
The patent employs LED indicators that display different colors or patterns to indicate the connectivity status and discoverability state of the PDU. This visual feedback mechanism helps users identify the correct PDU and understand its current state, resolving the difficulty of detecting and measuring PDU status among multiple units.
Solution Approach 2:
The system provides real-time feedback through LED indicators that show whether the PDU is in a discoverable state and whether a connection is active. This feedback mechanism allows users to monitor the connection status and identify the correct PDU, thereby improving ease of operation while reducing identification difficulty.
2Ease of operation
If continuous discoverability is enabled for Bluetooth PDU, then user connection is facilitated, but connection with unintended PDU is more likely
Solution Approach 1:
The patent implements dynamic discoverability where the PDU's discoverable state can be changed based on user interaction or system conditions. The LED indicators dynamically reflect the current discoverability state, allowing the system to balance ease of connection with connection accuracy by controlling when the PDU is discoverable.
Solution Approach 2:
Different LED colors or blinking patterns indicate different discoverability states, providing visual cues to users about the PDU's current state. This helps users understand when it is appropriate to initiate a connection, thereby improving both ease of operation and connection accuracy.
3Loss of information
If LED indicators are added to show connectivity status, then user awareness of connection state is improved, but device complexity increases
Solution Approach 1:
The patent uses LED indicators with different colors or blinking patterns to convey connectivity status information. This provides an intuitive visual interface that reduces information loss without requiring complex display systems or additional user interface components.
Solution Approach 2:
The LED indicators provide self-service by automatically displaying the connectivity status without requiring user configuration or external monitoring equipment. This simple visual feedback mechanism reduces information loss while adding minimal complexity to the PDU design.

AI summary
Methods, systems, and devices for wireless communication between a PDU and one or more devices within a limited communications range are described. A power distribution unit may be provided with a wireless communications module that may operate to communicate with user devices within a relatively close proximity. The wireless communications module may provide information reporting and may, in some examples, provide a user of the user device with configuration and other command capabilities.
