Solution Overview
Problem
Conventional multinational adapters are large, inconvenient to operate, prone to collision and deformation, and pose safety concerns due to exposed electrical pins that need adjustment for different socket specifications.
Innovation Solution
A portable adapter structure with a front cover, main body, and back cover, featuring press assemblies and elastic members that allow selective movement of electrical connection assemblies to conform to various national plug specifications, ensuring secure and convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrical pin group is exposed to facilitate screwing out, then the operation convenience is improved, but the pins are prone to collision and deformation
Solution Approach 1:
The adapter is divided into multiple independent modules: a housing, a retractable pin assembly, and a rotating connector. The pin assembly can be independently retracted into the housing for protection or extended for use, separating the storage function from the connection function to prevent collision and deformation.
Solution Approach 2:
The electrical pin assembly is designed to be dynamically retractable and rotatable rather than fixed. The spring-loaded mechanism allows the pins to automatically retract into the housing when not in use, eliminating exposure to collision while maintaining easy access when needed.
2Adaptability or versatility
If the adapter is designed to conform to various socket specifications, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The adapter incorporates a universal rotating connector that can be adjusted to different angular positions to accommodate various socket specifications (US, UK, European, Australian). This single multi-functional component replaces what would otherwise require multiple separate adapters, maintaining adaptability while simplifying the overall device structure.
Solution Approach 2:
The connector is designed with rotational freedom, allowing it to dynamically adjust its orientation to match different socket configurations. This dynamic adjustment capability enables one adapter to serve multiple countries' socket standards without requiring complex mechanical transformations.
3Volume of moving object
If the adapter structure is compact for portability, then the便携性 is improved, but the operation convenience deteriorates
Solution Approach 1:
The retractable pin assembly is nested within the housing, with the pins stored inside the housing body rather than externally mounted. This nesting arrangement minimizes the adapter's external dimensions for portability while allowing full extension of the pins when needed, maintaining compact size without compromising operational functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adapter is designed to be portable and secure, allowing easy adjustment to fit different socket specifications without deformation, enhancing safety and usability by using elastic members and guiding grooves for precise alignment and secure electrical connections.
Implementation Method 1
At least one elastic member is provided between the press assembly and the main body. One end of the elastic member contacts the main body, and the other end of the elastic member contacts the press assembly.
