Detachable Power Adapter Plug Guide for Wear-Resistant Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power adapters suffer from loose connections between the detachable plug and body due to worn guide rails, leading to safety hazards and increased replacement costs.
Innovation Solution
A power adapter design featuring a guide member with a plate portion, first slot, and guide rail, which allows for detachable connection between the plug assembly and body, enabling easy replacement of the guide member when worn, thus maintaining a strong and simplified connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a guide rail is used to connect the detachable plug and body, then the connection structure is simple, but the connection becomes loose after long-term use due to wear
Solution Approach 1:
The guide member is separated from the body and plug assembly, allowing it to be an independent replaceable component. This segmentation enables the guide member to be replaced when worn, maintaining connection reliability without replacing the entire power adapter.
Solution Approach 2:
The guide member is designed as a consumable component that can be discarded when worn and recovered/replaced independently. This allows the valuable body and plug assembly to be retained while only replacing the worn guide member, reducing overall replacement costs.
2Device complexity
If the guide rail is integrated into the body, then the structure is compact, but replacement costs increase when the guide rail wears out
Solution Approach 1:
The guide member is segmented as a separate component from the body and plug assembly. This allows selective replacement of only the guide member when worn, rather than replacing the entire integrated assembly, significantly reducing repair costs.
Solution Approach 2:
The guide member is designed as a lower-cost, replaceable component with limited service life. When worn, it can be replaced with a new guide member while retaining the more expensive body and plug assembly, making the system more economical over time.
3Ease of operation
If a detachable connection is used between plug assembly and body, then assembly and disassembly are easy, but connection strength may be reduced
Solution Approach 1:
The guide member acts as an intermediary component between the plug assembly and body, providing a dedicated interface for detachable connection. This intermediary structure enables easy assembly and disassembly while maintaining connection strength through proper mechanical engagement features.

AI summary
A power adapter includes a body, a plug assembly and a guide member. The body includes a shell and a cover plate. The shell and the cover plate are engaged with each other along a first direction to form a first cavity. The shell includes a recessed portion in which a positioning plate is provided. The plug assembly includes a first housing and a second housing. The first housing and the second housing are engaged with each other along a second direction to form a second cavity. The second housing defines a slide groove. The guide member is located at least partially in the recessed portion. The guide member includes a plate portion, a first slot and a guide rail. The positioning plate is adapted to the first slot. The guide rail is adapted to the slide groove.
