Solution Overview
Problem
Existing power converters with replaceable plugs have complex configurations and are difficult to assemble due to the need for various socket standards, making them not cost-effective.
Innovation Solution
A power converter design featuring a main body with a plug-receiving portion and a flexible fixing member, where the plug has inclined slants matching the main body's sidewalls, allowing for easy assembly and disassembly, and conductive terminals that can be rotated for different socket standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple diverse plugs are provided to comply with different socket standards, then adaptability is improved, but device complexity increases
Solution Approach 1:
The plug is separated from the main body as a replaceable component. The main body contains a standardized plug-receiving portion, while different plug types can be detached and replaced as needed. This segmentation allows the main body to remain simple while achieving adaptability through modular plug replacement.
Solution Approach 2:
The main body is designed with a universal plug-receiving portion that can accommodate multiple types of plugs. By providing a standardized interface and optional guiding slots, the main body can work with various plug configurations, achieving multi-functionality without increasing its own complexity.
2Ease of operation
If guiding slots and guiding tracks are added to facilitate plug assembly, then ease of operation is improved, but device complexity increases
Solution Approach 1:
Guiding slots and guiding tracks are provided optionally rather than mandatorily. The design allows for partial implementation where only essential guiding features are included, or additional guiding features can be added based on specific application needs. This partial action approach improves ease of operation without necessarily increasing complexity in all cases.
3Reliability
If a resilient fixing member is used to secure the plug, then reliability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The resilient fixing member is designed to automatically engage with the plug upon insertion into the plug-receiving portion. The elastic deformation and automatic resetting of the fixing member occur without external assistance, providing self-service fixation that ensures reliable connection while simplifying the assembly process.

AI summary
An electronic device includes a main body, a plug and a fixing member. The main body includes a plug-receiving portion and a plurality of conductive portions. The plug-receiving portion is defined by a first sidewall, a second sidewall and a bottom surface. The first sidewall is opposed to the second sidewall. The bottom surface is connected to the first sidewall and the second sidewall. An inclined angle between the bottom surface and at least one of the first sidewall and the second sidewall is smaller than 90 degrees. The plug includes a plurality of conductive terminals, a first slant corresponding to the first sidewall, and a second slant corresponding to the second sidewall. The fixing member is used for facilitating fixing the plug in the plug-receiving portion of the main body such that the conductive terminals of the plug are electrically connected to the conductive portions of the main body.
