Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a wearable device includes multiple battery receptacles and a battery pack bank, then power supply duration and versatility are improved, but device complexity and size increase
Solution Approach 1:
The battery system is segmented into multiple independent battery packs that can be individually inserted into separate receptacles. Each battery pack operates independently, allowing the system to manage power from multiple sources through a battery pack bank that tracks and controls power distribution from each segment separately.
Solution Approach 2:
The wearable device incorporates multiple battery receptacles that can accept different types of battery packs, creating a universal power system. The battery pack bank serves multiple functions including power management, state-of-charge tracking, and coordination between multiple battery sources, making the system adaptable to various power supply scenarios.
2Duration of action of moving object
If a wearable device includes multiple battery receptacles and a battery pack bank, then power supply duration is improved, but device size increases
Solution Approach 1:
The battery packs are designed to be nested within the wearable device structure. Multiple battery receptacles are integrated into the device housing, and the battery pack bank is nested within the same structure, allowing compact arrangement of multiple power sources without proportionally increasing overall device volume.
3Adaptability or versatility
If an adaptor switches power between multiple battery receptacles, then power distribution flexibility is improved, but device complexity increases
Solution Approach 1:
The battery pack bank serves as an intermediary between multiple battery receptacles and the power tool. It manages the complexity of switching and coordinating power from multiple sources, providing a simplified interface that handles state-of-charge tracking and power distribution decisions without requiring complex control circuitry in each receptacle.

AI summary
A system including a power tool, a device, one or more battery packs, a battery pack bank, and an adaptor. The power tool has a power tool battery receptacle. The device is wearable by a user and has a first device battery receptacle and a second device battery receptacle. The one or more battery packs are received by at least one selected from a group of the power tool battery receptacle, the first device battery receptacle, and the second device battery receptacle. The battery pack bank is on the device. The adaptor includes a user interface and an adapter interface, the adapter interface is received by the power tool battery receptacle, the adapter configured to supply power, via the first device battery receptacle, when the user interface is in a first mode, and supply power, via the second device battery receptacle, when the user interface is in a second mode.
