Dual Plug Charger Pivot Mechanism for Global Receptacle Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices require multiple adapters to charge in different geographic locations due to varying power supply standards and receptacle structures, leading to inconvenience and potential electrical safety issues.
Innovation Solution
A dual plug charger with a pivotally mounted design, featuring a set of first pins oriented at a 90° angle to a set of second pins, allowing it to fit into two different types of electrical supply receptacles by pivoting between charging positions, with pin pockets for safe stowage and electrical isolation to prevent interference and shock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single charger is designed to work in multiple geographic locations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The charger head is designed with two different sets of pins (first pins and second pins) that can be selectively positioned to mate with different types of power supply receptacles. This universal design allows a single charger to function across multiple geographic locations with different electrical standards, eliminating the need for multiple chargers while maintaining adaptability.
Solution Approach 2:
The charger head is made pivotally mounted within the plug reservoir, allowing it to rotate between different orientations. This dynamic mechanism enables the charger to switch between displaying/using the first pins and second pins by pivoting the charger head to different positions, providing adaptability to different receptacle types without requiring a completely separate charger for each location.
2Adaptability or versatility
If multiple adapters are used for different geographic locations, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
Multiple adapter functions are merged into a single charger unit. The first pins and second pins are integrated into one charger head that can be pivotally positioned, allowing users to charge their devices in different geographic locations without carrying multiple separate adapters. This consolidation improves ease of operation by reducing the number of components users must manage.
Solution Approach 2:
The single charger is designed to perform multiple functions by accommodating different pin configurations. Users only need to carry one charger that can adapt to various power supply receptacles worldwide, significantly improving convenience compared to carrying multiple location-specific adapters.
3Volume of moving object
If pins are positioned close together for compact design, then volume is reduced, but electrical safety deteriorates
Solution Approach 1:
The charger head structure incorporates localized electrical isolation features between the first pins and second pins. Insulating materials or structural barriers are applied specifically in the regions where pins are positioned, providing targeted electrical safety without requiring the entire charger to be oversized. This allows compact design while maintaining safety through localized quality enhancements.
