Compact Pin Combination Structure for Power Converters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional power converters with multiple pins have a large volume due to separate pin settings, making them inconvenient to travel with and affecting user experience.
Innovation Solution
A pin combination structure for power converters that includes a European standard pin assembly with a British standard ground wire yielding groove, allowing the British standard ground wire pin to move within the European standard socket, reducing overall size and incorporating European and British standard pin assemblies with sliding mechanisms for efficient use and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pins are set separately in traditional power converters, then the pins can function independently, but the overall volume of the power converter becomes large
Solution Approach 1:
The patent combines multiple pin functions into a single integrated structure. The European standard pin assembly and British standard pin assembly share common components including the housing, elastic element, and limiting mechanism. The British standard ground pin can move within the European standard pin assembly structure, allowing both pin types to coexist in a compact unified design rather than requiring separate independent assemblies for each standard.
Solution Approach 2:
The British standard ground pin is nested within the European standard pin assembly structure. The moving groove is formed within the European standard pin assembly housing, allowing the British standard ground pin to move up and down within the confines of the European standard structure. This nesting arrangement enables space-efficient coexistence of multiple pin standards.
2Volume of stationary object
If the power converter is made smaller for travel convenience, then portability improves, but the pins may interfere with each other
Solution Approach 1:
The British standard ground pin is designed to move dynamically within the moving groove of the European standard pin assembly rather than being fixed. The elastic element provides dynamic force to push the British standard ground pin outward when needed. This dynamic design allows compact arrangement while preventing interference through controlled movement rather than rigid positioning.
Solution Approach 2:
The pin assembly is segmented into distinct functional zones with the moving groove providing a dedicated path for the British standard ground pin. The limiting groove and limiting protrusion create segmented movement boundaries that prevent the pins from interfering with each other while maintaining compact overall dimensions.
3Device complexity
If the British standard ground pin is fixed in position, then the structure is simple, but space cannot be saved in the power converter
Solution Approach 1:
The British standard ground pin transitions from a fixed position to a movable position within the moving groove. The elastic element provides the dynamic mechanism to push the pin outward during use. This dynamic approach increases structural complexity slightly but enables significant space savings by allowing the pin to be nested within the European standard pin assembly when not in use.

AI summary
The invention discloses a pin combination structure for a power converter with smaller volume, which comprises a European standard pin assembly arranged in the power converter and a British standard pin assembly arranged in the power converter. The British standard pin assembly comprises a British standard ground pin arranged in the power converter, and the European standard pin assembly comprises a European standard insert sleeve arranged in the power converter, wherein the middle part of the European standard insert sleeve is formed with a British standard ground wire abdicating groove which is concave inwards and matched with the British standard ground wire pin, and the British standard ground wire pin moves up and down in the British standard ground wire abdicating groove. The invention saves the space in the power converter, makes the power converter smaller, is more convenient to travel and carry, and improves the use experience of the power converter.
