Rotatable Power Supply Plug with Positioning Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supplies with detachable plugs are inconvenient due to the need for multiple adapters and fixed plugging directions, which can cause deformation and hinder placement, especially when the device's orientation changes.
Innovation Solution
A power supply with a detachable multi-directional plug that allows for easy assembly and disassembly, featuring a braking ring with positioning grooves for metallic terminals, enabling multi-directional rotation without the need for removing the plug, ensuring good electrical conductivity and reduced wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the plug is fixed to the wall with a fixed plugging direction, then the structure is simple, but the adaptability is poor and deformation occurs when the plugging direction does not match the wire arrangement
Solution Approach 1:
The plug is designed to be rotatable relative to the power supply body through a docking space, allowing the plugging direction to be dynamically adjusted to match different wire arrangement directions and device orientations, resolving the contradiction between fixed structure and adaptability requirements
Solution Approach 2:
The plug assembly is segmented into separable components (plug head and base) that can be independently positioned and rotated, enabling flexible directional adjustment while maintaining a relatively simple overall structure
2Ease of operation
If the plug is removed and rotated to change plugging direction using sliding connection, then the plugging direction can be changed, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The plug can be rotated in place within the docking space without complete removal, enabling quick directional changes. The snap block and release button mechanism allows for rapid detachment and reattachment, significantly reducing the time and effort required to change plugging direction compared to traditional sliding connection methods
3Adaptability or versatility
If the plug is completely detached to change direction, then the plug can be repositioned, but the assembly and disassembly process becomes complex and troublesome
Solution Approach 1:
The plug assembly is divided into a plug head and base that can be separately manipulated. The base with positioning grooves and the plug head with corresponding positioning protrusions create a simple yet effective repositioning mechanism that reduces assembly complexity while maintaining full repositioning capability
Solution Approach 2:
The plug can be dynamically repositioned by rotating it to different angles within the docking space and securing it at the desired orientation using the snap block mechanism, eliminating the need for complete disassembly and complex reassembly procedures
