Replaceable Plug Power Supply Unit Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply units are not universally compatible due to varying plug shapes and sizes, and directional constraints, limiting their use across different countries and devices.
Innovation Solution
A power supply unit design featuring a main body with a protruding plug mounting seat, guide rails, engagement blocks, and stoppers allows for interchangeable plugs that can be assembled in multiple directions, ensuring secure and flexible electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a latch mechanism is used to secure interchangeable plugs, then the design is simple, but the mounted plug unseats easily under external forces
Solution Approach 1:
The plug mounting mechanism is divided into separate functional components: guide rails for insertion guidance, engagement blocks with engagement slots for secure locking, and stoppers for position limitation. This segmentation allows each component to perform its specific function effectively, resolving the contradiction between simple design and reliable mounting.
Solution Approach 2:
The plug is nested within the receiving region formed by the plug mounting seat, with the guide rails, engagement blocks, and stoppers arranged in a nested configuration. The engagement blocks are positioned within the periphery of the receiving region, and the stoppers are received by engagement slots, creating a nested structure that ensures secure mounting while maintaining design simplicity.
2Device complexity
If the pin direction is fixed in conventional power supply units, then the structure is simple, but it creates inconvenience and constraint when plugging the power supply units
Solution Approach 1:
The plug mounting mechanism is designed to be dynamic rather than fixed. The guide rails allow the plug to be inserted at different orientations, and the engagement blocks with engagement slots enable the plug to be secured in multiple directions. This dynamic design allows users to plug the power supply unit in different directions according to the available space and power outlet orientation.
3Adaptability or versatility
If universal power adaptors are developed to be compatible with different plugs and outlets, then compatibility is improved, but the physical structure becomes complex and problem-prone
Solution Approach 1:
The power supply unit is designed with universal compatibility through the standardized plug mounting mechanism. The guide rails, engagement blocks, and stoppers create a universal interface that can accommodate different plug types and orientations. This universal design allows the same main body to work with various plugs without requiring complex adaptable structures.

AI summary
The instant disclosure relates to a power supply unit that is compatible with different plug types and can be plugged to the power outlet at different directions. The power supply unit comprises a main body and a plug. The plug can be assembled to and connected electrically with the main body with ease. The power supply unit can be used more broadly in different regions and provide more options when plugging to the power outlet.
