Locking Combination Outlet Module for Secure PDU Plug Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power distribution units (PDUs) lack flexibility in accommodating various plug types and often experience insecure electrical connections, which can lead to equipment downtime and operational disruptions in data centers and other critical environments.
Innovation Solution
The development of locking combination outlet modules that incorporate multiple outlet cores and latch levers, allowing for secure engagement with various plug types such as C13, C19, C14, and C20, while providing flexibility in outlet configurations to match different equipment requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional PDUs use standard outlets without locking features, then ease of operation is improved, but reliability deteriorates due to insecure electrical connections
Solution Approach 1:
The latch lever is designed to be movable between a first position (engaging the plug) and a second position (disengaged from the plug). This dynamic mechanism allows the outlet to transition between locked and unlocked states, providing secure connection when needed while maintaining ease of operation when the latch is released.
Solution Approach 2:
The outlet module changes its operational parameter by introducing a latch mechanism that can be toggled between engaged and disengaged states. This parameter change allows the same outlet to provide both secure locked connections and easy unplugging functionality, resolving the contradiction between reliability and ease of operation.
2Adaptability or versatility
If PDUs are manufactured with fixed outlet configurations, then manufacturing precision is improved, but adaptability deteriorates when equipment requirements change
Solution Approach 1:
The outlet module is designed with multiple outlet cores (e.g., C13, C19, combination outlets) within a single standardized housing. This universal design allows one module type to serve multiple equipment configurations, providing adaptability without requiring multiple specialized PDU models.
Solution Approach 2:
The PDU system is divided into modular outlet units that can be independently configured. Each outlet module is a self-contained unit with specific outlet types, allowing the overall PDU to be customized by selecting different module combinations while maintaining standardized manufacturing for each module type.
3Reliability
If PDUs lack locking features, then device complexity is reduced, but reliability deteriorates due to risk of accidental disconnections
Solution Approach 1:
The latch lever is designed to automatically engage with the plug upon insertion, providing self-locking functionality without requiring additional active components or complex control mechanisms. The resilient member automatically returns the latch to the engaged position, creating a passive reliability enhancement.
Solution Approach 2:
The resilient member acts as an intermediary between the latch lever and the housing, providing the necessary force to maintain engagement. This simple mechanical intermediary enables reliable locking without requiring complex actuation systems or additional energy sources.

AI summary
An outlet module including a module housing comprising a base surface and a sidewall extending therefrom to at least partially surround an interior region. Multiple outlet cores extend from the base surface and at least one latch lever is pivotably coupled to the sidewall and adjacent a corresponding one of the multiple outlet cores. The latch lever is moveable between a first position, wherein the at least one latch lever is capable of engaging a mating plug and a second position, wherein the at least one latch lever is disengaged from the plug.
