Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional battery pack uses a single connection member design, then the structure is simple, but it cannot match power tools in different use environments
Solution Approach 1:
The battery pack connection interface is segmented into multiple independent connection members (first connection member and second connection member), each with different shapes and sizes. This segmentation allows each connection member to be specifically designed for different power tool types, enabling the battery pack to match various tools in different use environments without requiring a completely different battery pack design.
2Adaptability or versatility
If the battery pack includes multiple connection members of different shapes and sizes, then it can match different electrical devices, but the connection members may interfere with each other
Solution Approach 1:
The first connection member and second connection member are designed with asymmetric shapes and sizes, where they do not match each other's latching interfaces. This asymmetric design ensures that when one connection member is engaged with its corresponding electrical device, the other connection member cannot interfere with the latching operation. The asymmetric geometry creates a situation where each connection member is uniquely compatible only with its intended partner, eliminating interference while maintaining ease of operation.
3Volume of moving object
If the connection members are positioned closely together, then the battery pack size is reduced, but they may interfere with each other during latching
Solution Approach 1:
The battery pack housing serves as an intermediary structure that positions and isolates the first and second connection members. The housing includes specifically designed latching interfaces that guide and constrain the connection members, ensuring they operate independently without interfering with each other even when positioned in close proximity. This intermediary housing structure allows compact battery pack design while maintaining ease of latching operation.

AI summary
A multipurpose battery pack includes: a housing, and a battery cell and a circuit board that are disposed in the housing; a first electrical connector connecting one of positive and negative electrodes of the battery cell to the circuit board; a second electrical connector connecting the other one of the positive and negative electrodes of the battery cell to the circuit board; a third electrical connector disposed on the circuit board and including at least one interface, where the interface is adapted to be electrically connected to an external electrical device, to supply power from the battery cell to the electrical device through the third electrical connector; a first connection member adapted to be in a latching connection with a first electrical device; and a second connection member adapted to be in a latching connection with a second electrical device.
