Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power distribution units (PDUs) lack flexibility in accommodating various plug types and do not provide secure connections, leading to potential disconnections that can disrupt critical operations in data centers and other computing facilities.
Innovation Solution
The development of locking combination outlet modules with pivotable latch levers and resilient members that securely engage mating plugs, allowing for flexibility in accommodating multiple plug types such as C13, C19, and combination outlets, ensuring secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional PDUs use fixed outlet configurations, then manufacturing is simple, but adaptability to different plug types is poor
Solution Approach 1:
The outlet module incorporates multiple outlet cores (C13, C19, and combination outlets) within a single standardized housing, allowing one PDU design to accommodate various plug types. This multi-functional approach eliminates the need for multiple specialized PDU variants while maintaining manufacturing efficiency through modular core assemblies.
Solution Approach 2:
The PDU system is divided into interchangeable outlet core modules that can be selectively positioned within standardized housings. This segmentation allows flexible configuration of outlet types and positions without redesigning the entire PDU, resolving the contradiction between adaptability and manufacturing complexity.
2Reliability
If conventional PDUs use simple outlet connections, then device complexity is low, but connection security is poor leading to accidental disconnections
Solution Approach 1:
The latch lever is pre-positioned in a locked state that automatically engages with the plug upon insertion. This preliminary positioning ensures that connections are secured by default without requiring additional user actions, thereby improving reliability while adding minimal complexity to the connection process.
Solution Approach 2:
The resilient member automatically actuates the latch lever into the locked position when a plug is inserted, and the latch lever self-releases when force is applied to the release tab. This self-service mechanism secures connections without external intervention while maintaining simple operation through intuitive manual release.
3Reliability
If PDUs are designed for critical data center operations, then reliability is high, but any disconnection causes harmful effects to business operations
Solution Approach 1:
The locking mechanism proactively prevents disconnection by automatically securing plugs upon insertion and requiring deliberate action to release. This preliminary anti-action counteracts the potential harmful effect of accidental disconnections before they can occur, ensuring continuous power supply to critical data center equipment.

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.
