Detachable Plug Assembly for Multi-Standard Mains Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing consumer electronic devices face inconvenience due to fixed power converter plugs that do not adapt to varying mains socket specifications across different countries, requiring additional adapters.
Innovation Solution
An electronic device with a detachable plug system, featuring a main body with a fitting recess and conductive terminal group, and a plug body with a power pin group and conductive terminal group, allowing for interchangeable plug bodies to fit different mains socket specifications, while utilizing a hidden connection structure for improved appearance and water resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed plug is used in the power converter, then the structure is simple and manufacturing is easy, but the device cannot adapt to different mains socket specifications around the world
Solution Approach 1:
The plug is divided into a fixed base portion integrated with the power converter and a detachable plug body that can be removed and replaced. This segmentation allows the plug body to be changed according to different mains socket specifications while keeping the main power converter structure simple and unchanged.
Solution Approach 2:
The plug transitions from a static fixed structure to a dynamic interchangeable structure. The plug body can be detached and reattached, allowing the device to adapt to different electrical environments. The retaining wall and elastic element provide a mechanism for secure attachment while allowing easy replacement when needed.
2Shape
If traditional visible connection structures are used, then assembly is simple, but the product appearance is compromised and water ingress risk increases
Solution Approach 1:
The plug body is inserted into and nested within the power converter housing. The connection structure is concealed inside the housing, with only the power pins visible from the outside. This nested arrangement hides the connection mechanism, improving appearance and providing protection against water ingress while maintaining a clean, integrated look.
Solution Approach 2:
The retaining wall and elastic element act as intermediary components that facilitate the connection between the plug body and power converter internally. These intermediary structures enable secure attachment while remaining hidden within the device, allowing simple assembly mechanisms to be concealed from view.

AI summary
An electronic device with a detachable plug includes a main body and a plug body. The main body has a fitting recess, a first conductive terminal group, and a press portion. The first conductive terminal group is disposed in the fitting recess. The press portion is located on at least one side of the fitting recess, and the press portion is formed by at least one exterior side plate and at least one interior side plate of the main body together. A press space exists between the at least one exterior side plate and the at least one interior side plate. The at least one interior side plate has an opening communicating with the fitting recess, and the at least one exterior side plate has a bump passing through the opening. The plug body is detachably configured in the fitting recess of the main body.
