Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If battery units are integrated with power supply devices, then power output capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the battery unit and power supply device into an integrated system where the battery unit is placed on the upper surface of the power supply device body case. The engaging parts mechanically couple these components, allowing the battery to directly power external apparatuses through the power supply device's output parts, thereby improving power output capability while managing complexity through functional integration.
Solution Approach 2:
The power supply device is designed with universal engagement interfaces that can accommodate different battery units. The body case structure with upper surface placement and standardized engaging parts allows the same power supply device to work with multiple battery configurations, providing multi-functionality without proportionally increasing device complexity.
2Ease of operation
If battery units can be easily coupled and decoupled, then ease of operation is improved, but connection reliability may worsen
Solution Approach 1:
The connection system is segmented into separate engaging parts on both the power supply device and battery unit. This allows independent engagement and disengagement of connection elements, enabling easy coupling and decoupling operations while maintaining secure connections through distributed engagement points that ensure reliable electrical and mechanical contact.

AI summary
A power supply device may include a body case, a first device-side engaging part disposed on the body case, a first output part disposed on the body case; and a device-side connector configured to be connected with a battery-side connector of a first battery unit. The body case may include a bottom surface, and an upper surface configured to allow the first battery unit to be placed thereon. The first device-side engaging part may be configured to be engaged with a first engaged part of the first battery unit. The first output part may be configured to output power supplied from the first battery unit to a first external apparatus different from the first battery unit.
