Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-voltage battery pack is designed with a multi-voltage output interface, then the battery pack can be matched with multiple power tools, but the output interface is not coupleable with the input interface of single-voltage power tools
Solution Approach 1:
The patent introduces an adapter as an intermediary device that bridges the incompatibility between multi-voltage battery packs and single-voltage power tools. The adapter contains a switching mechanism with multiple switching elements that can selectively connect different battery terminals to the power tool terminals, enabling a single adapter to support both single-voltage and multi-voltage battery packs with single-voltage power tools.
2Reliability
If different power tools are equipped with specific battery packs for their rated voltages, then each power tool operates reliably, but maintenance difficulty increases and storage space is occupied
Solution Approach 1:
The patent makes the adapter universal by designing it to accept both single-voltage and multi-voltage battery packs while working with single-voltage power tools. The switching mechanism automatically or manually configures the appropriate voltage output based on the inserted battery pack type, allowing one adapter to perform multiple functions and eliminate the need for multiple specialized battery packs.
3Adaptability or versatility
If users equip multiple battery packs in various specifications for different power tools, then all power tools can be used, but resource waste occurs due to idle battery packs
Solution Approach 1:
The patent merges the functionality of multiple specialized battery packs into a single multi-functional adapter system. By combining the ability to accept both single-voltage and multi-voltage battery packs with switching capability in one device, users can consolidate their battery pack collection and reduce resource waste from idle batteries.

AI summary
An adapter comprises an input port being coupleable with a single-voltage output interface of a single-voltage battery pack or a multi-voltage output interface of a multi-voltage battery pack, an output port electrically connected to the input port and being coupleable with a single-voltage input interface of a first power tool or a multi-voltage input interface of a second power tool, a switching mechanism being switchable between a first state and a second state. When the switching mechanism is in the first state, the input port is coupled with the single-voltage output interface and the output port is coupled with the multi-voltage input interface of the second power tool, when the switching mechanism is in the second state, the input port is coupled with the multi-voltage output interface and the output port is coupled with the single-voltage input interface of the first power tool.
