Layered Plug Converter Pin Assembly for Compact Multi-Socket Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug converters have a low internal part utilization rate and space utilization rate due to the inefficient arrangement of different type plugs, making them bulky and inconvenient to carry, especially when traveling.
Innovation Solution
A plug converter design featuring a support assembly with a first and second support frame, pin assemblies arranged layer by layer, and propelling devices that allow pin assemblies to slide between active and inactive positions, optimizing space and enabling efficient electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different type plugs are placed in the housing of a plug converter, then the plug converter can support multiple countries' power sockets, but the plugs occupy much space in the housing resulting in low part utilization rate and low space utilization rate
Solution Approach 1:
The plug converter is divided into multiple pin assemblies (first pin assembly with two first pins, second pin assembly with two second pins, third pin assembly with three pins) that can be independently arranged and positioned. Each pin assembly corresponds to different country standards, allowing selective deployment without requiring all pins to occupy space simultaneously.
Solution Approach 2:
The pin assemblies are arranged layer by layer in sequence along the vertical direction, with the first pin assembly at the first position, second pin assembly at the second position, and third pin assembly at the third position. This multi-level vertical arrangement efficiently utilizes the housing's vertical space, transforming a two-dimensional space utilization problem into a three-dimensional solution.
2Adaptability or versatility
If multiple different type plugs are placed in the housing of a plug converter, then the plug converter can support multiple countries' power sockets, but the plugs occupy much space in the housing resulting in low part utilization rate
Solution Approach 1:
The housing is designed as a universal container that accommodates multiple types of pin assemblies through standardized positioning structures. The support board provides universal mounting points for different pin assemblies, and the guide devices (guide rods and guide blocks) provide universal guidance for all pin assemblies during insertion and retraction, reducing the need for separate complex mechanisms for each pin type.
Solution Approach 2:
The pin assemblies are designed to be movable rather than fixed, allowing them to be inserted into and retracted from the housing. This dynamic arrangement enables the plug converter to adapt its configuration based on usage needs, with pin assemblies being pushed out by propelling devices when needed and retracted when not in use, optimizing both space utilization and structural simplicity.
