Rotating Multi-Plug Adapter for Universal Socket Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug adapters require users to carry multiple plugs of different specifications, leading to a heavy luggage burden and increased risk of loss, causing inconvenience and disruption in the use of electronic devices.
Innovation Solution
A plug adapter with a rotating housing and multiple plug assemblies, including guide protrusions, guide rods, and reset springs, allowing users to switch between different plug types by rotating the housing, eliminating the need to carry multiple plugs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users carry multiple plugs of different specifications to adapt to different countries' power sockets, then compatibility with various power sockets is improved, but the weight of moving object increases and the reliability decreases due to increased risk of loss
Solution Approach 1:
The patent combines multiple plug assemblies (first, second, and third plug assemblies with different specifications) into a single integrated rotating housing structure. This allows users to have multiple plug types in one device rather than carrying separate plugs, reducing luggage weight while maintaining compatibility with various power sockets across different countries.
Solution Approach 2:
The rotating housing is designed to accommodate multiple plug assemblies with different specifications, making the single adapter device universally applicable to various power socket types. The device can be rotated to select and present the appropriate plug assembly for the target country's power socket standard.

3Weight of moving object
If a rotating housing with multiple plug assemblies is used to reduce the number of plugs to carry, then the weight of moving object is reduced, but the device complexity increases
Solution Approach 1:
The adapter device is segmented into distinct functional modules: a rotating housing containing multiple plug assemblies, guide rods for movement control, reset springs for positioning, and a panel for operation. This modular segmentation allows each component to perform its specific function efficiently while keeping the overall structure organized and manageable despite the multi-functional requirement.
Solution Approach 2:
The rotating housing introduces dynamic functionality to the adapter, allowing it to rotate and present different plug assemblies as needed. This dynamic mechanism enables a single device to replace multiple static plugs, reducing weight while the structured rotation system keeps the complexity controlled through defined movement paths guided by guide rods and springs.
