Solution Overview

Problem

Conventional power distribution units face challenges in space efficiency and the need to accommodate multiple types of receptacles to meet current and future requirements within computer racks and cabinets, where space is limited and the type of receptacles must be adaptable.

Innovation Solution

A multiple receptacle assembly that can be configured within a standard size casing, allowing for the inclusion of various receptacles such as C13, C14, C19, and C20 types, with adjustable configurations using tabs, covers, and slider mechanisms, and a locking mechanism to secure plugs, ensuring compatibility and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a power distribution unit includes multiple types of receptacles to meet current and future requirements, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvereceptacle type compatibilityVSAvoidreceptacle configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal receptacle design that can accept multiple plug types (C13, C14, C19, C20) through a single receptacle unit. This multi-functional approach eliminates the need for separate receptacles for each plug type, thereby improving adaptability while actually reducing device complexity compared to having multiple dedicated receptacles.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent employs adjustable configurations using tabs, covers, and slider mechanisms that can be dynamically adjusted to accommodate different plug types. The locking mechanism can be engaged or disengaged based on the required plug type, providing dynamic adaptability without permanent complex wiring for each configuration.

Inventive Principle:
Principle #15Dynamics

2Area of stationary object

If the power distribution unit is made compact to optimize space usage, then space efficiency is improved, but ease of operation decreases

Engineering Contradiction:
ImprovePDU footprintVSAvoidplug insertion ease
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent combines multiple receptacle functions into a single compact unit that can accommodate various plug types. By merging what would traditionally require separate receptacles into one multi-functional unit, the overall footprint is reduced while maintaining operational ease through a unified interface design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adjustable tabs, covers, and slider mechanisms are designed to be easily manipulated despite the compact size. The locking mechanism provides secure connection while remaining accessible for quick engagement and disengagement, maintaining ease of operation within the reduced form factor.

Inventive Principle:
Principle #15Dynamics

AI summary

The present disclosure is an apparatus for providing a multiple receptacle assembly whereby a number of receptacles could be configured within a single assembly of a standard size. It is contemplated that more receptacles may be available in a particular size and width than conventional power distribution units. Additionally, in another aspect of the present disclosure, the present disclosure is directed to an apparatus for providing power for multiple types of plugs via a single receptacle. In one embodiment of the disclosure, apparatus for providing power for multiple types of plugs via a single receptacle may provide power to one of a C14 plug or a C20 plug via a single receptacle, whereby the single receptacle may be configured to operate as a C13 and C19 receptacle and in compliance with IEC60320 standards.
