Universal Power Adapter with Selector Circuit for Backup Battery Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inability to mate power ports among different digital products leads to high manufacturing costs and limited utilization of backup batteries, as manufacturers must produce various types of power sockets to match specific products.
Innovation Solution
A universal purpose power adaptor with first and second boxes, each containing terminal blocks, plugs, and selector circuits, allowing a backup battery to be connected to any digital product via a standard socket and plug configuration, eliminating the need for multiple power socket types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manufacturers prepare different types of power sockets to match specific digital products, then compatibility with specific products is improved, but manufacturing costs increase and device complexity increases
Solution Approach 1:
The patent implements a universal power socket design that can accept multiple plug types (USB Type-C, USB Type-A, Micro USB) through a single interface. The socket structure includes a guiding hole with positioning structures that can accommodate different plug geometries, allowing one power bank to charge various digital products without requiring multiple specialized sockets. This multi-functional design directly resolves the contradiction by maintaining product compatibility while reducing the number of power socket types needed.
2Adaptability or versatility
If manufacturers prepare different types of power sockets to match specific digital products, then product compatibility is improved, but manufacturing costs increase
Solution Approach 1:
By designing a single power socket that can accommodate multiple plug types through integrated positioning structures and contact arrangements, the patent eliminates the need for manufacturers to produce and inventory multiple specialized power sockets. This universal design reduces manufacturing complexity, material costs, and assembly operations while maintaining the ability to charge different digital products, thereby resolving the contradiction between product compatibility and manufacturing cost.
3Reliability
If different power socket types are used for different digital products, then specific product matching is improved, but utilization of backup batteries decreases
Solution Approach 1:
The patent creates a universal power interface that maintains reliable electrical connection across different plug types through standardized contact arrangements and guiding structures. The socket is designed with multiple contact points that can establish reliable connections with various plug types (Type-C, Type-A, Micro USB), enabling a single backup battery to reliably charge multiple different digital products. This resolves the contradiction by preserving connection reliability while significantly expanding backup battery utilization across different device types.

AI summary
A universal purpose power adapter has a first box and a second box, in which the first box includes a first socket, a first plug and first terminal blocks, and the second box further comprises a second plug and second terminal blocks. The second plug couples to the first socket and to the power output port at the same time; the first plug couples to the charging port of the backup battery. A backup battery can be connected to a digital product via the power adaptor. A selector circuit in each of the first and second boxes, and coupled, facilitates power routing through the connected boxes.
