Adaptable Electrical Plug Assembly with Interchangeable Adapter Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for electronic devices that require compatibility with different voltage sources involve additional costs due to the need for multiple power supply cords and adapters, as existing plugs are not adaptable to various receptacle configurations.
Innovation Solution
An adaptable electrical plug assembly with interchangeable adapter plates that meet different standards, such as NEMA 5-15P and NEMA 6-20P, allowing a single power cord to operate with various voltage sources by adjusting the orientation of the power blades within a common plug housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed plug configuration is used for a specific voltage standard, then safety and operability for that standard are ensured, but compatibility with other voltage standards is lost
Solution Approach 1:
The plug is divided into a base housing and interchangeable adapter plates. Each adapter plate is a separate segment that can be attached or removed to change the plug's configuration. This segmentation allows the same base plug to work with different voltage standards by simply changing the adapter plate, resolving the contradiction between reliability for a specific standard and adaptability to multiple standards.
Solution Approach 2:
The base plug housing is designed as a universal component that can accommodate different adapter plates for various voltage standards (NEMA 5-15, NEMA 6-20, etc.). This multi-functionality allows a single plug base to serve multiple purposes across different voltage standards, maintaining safety and operability for each standard while achieving broad compatibility.
2Adaptability or versatility
If multiple power supply cords with different plugs are provided, then compatibility with different voltage standards is achieved, but device complexity and cost increase
Solution Approach 1:
The invention merges multiple plug configurations into a single base plug housing by using interchangeable adapter plates. Instead of requiring separate power supply cords for different voltage standards, the user keeps one power supply cord and swaps adapter plates as needed. This combining approach reduces the total number of cords and adapters from multiple separate units to a single modular system.
Solution Approach 2:
The plug configuration becomes dynamic rather than fixed. The adapter plates can be quickly attached or removed to change the plug's functionality on demand. This dynamic adaptability allows the same physical plug to transform between different voltage standard configurations, eliminating the need for multiple static power supply cords.
3Adaptability or versatility
If adapter plates are made interchangeable and removable, then adaptability to different standards is improved, but connection stability may be compromised
Solution Approach 1:
The connection system is segmented into the base plug housing and the adapter plate, with a dedicated interface between them. This segmentation allows for a specialized connection mechanism that ensures stable electrical and mechanical contact while still permitting easy removal and replacement of the adapter plate segment.

AI summary
An electrical plug assembly including a plug housing, a ground pin and a first power blade projecting from the surface of the plug housing; and a power socket disposed within the plug housing. The surface defines an aperture surrounding the power socket. The assembly further includes an adapter plate including a second power blade having a first portion projecting from a first surface and a second portion projecting from an opposed second surface. Ground pin and first power blade apertures extend through the adapter plate. The second portion of the second power blade is received within the power socket and the ground pin and the first power blade are received within the ground pin and first power blade apertures respectively. The ground pin and the first power blade each project from the first surface of the adapter plate. The adapter plate allows the plug assembly to meet NEMA 5-15P or 6-20P standards.
