Split-Housing Travel Adaptor for Flexible Plug Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing travel adaptors integrate input and output ports on the same housing, limiting device placement flexibility and being constrained by power supply line length, especially in confined spaces.
Innovation Solution
A travel adaptor design with a first housing containing slidably mounted pins and a second housing with jacks, connected by an extension wire, allowing separate placement and adaptable to various power standards, with rubber sealing sleeves for protection and positioning features for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If input ports and output ports are integrated on the same housing, then the adaptor structure is compact and simple, but the device placement flexibility is limited and the user is constrained by power supply line length
Solution Approach 1:
The adaptor is divided into two separate housings: a first housing for input ports and a second housing for output ports. These housings are connected via an extension wire, allowing the user to physically separate the power source from the device being charged. This segmentation resolves the contradiction by maintaining structural simplicity while dramatically improving placement flexibility and adaptability to different spatial configurations.
2Productivity
If multiple output ports are integrated on one housing, then the adaptor can charge multiple devices simultaneously, but the space utilization becomes inflexible and constrained by fixed socket locations
Solution Approach 1:
By separating the multi-output housing from the input housing and connecting them with an extension wire, the system maintains the ability to charge multiple devices simultaneously while allowing the output housing to be positioned anywhere within wire reach. This resolves the contradiction between multi-device charging capability and spatial flexibility.
3Device complexity
If the adaptor housing contains all ports, then the structure is compact, but the risk of overheating in high load use increases
Solution Approach 1:
Separating the input and output ports into different housings physically distributes the thermal load across two separate units rather than concentrating all power handling components in one housing. This reduces the risk of overheating in high-load scenarios while maintaining a relatively simple overall structure through the use of a flexible extension wire connection.
