Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an integrated battery is used in the wearable device, then the device structure is compact and unified, but the battery cannot be removed by the user and manufacturing complexity increases
Solution Approach 1:
The wearable device is divided into separate modules: a removable battery module and a device body. The battery module includes a battery, a first detachment feature, and a first set of electrical contacts, while the device body includes a second detachment feature and a second set of electrical contacts. This segmentation allows the battery to be independently removed and replaced by the user without affecting other device components, thereby improving ease of operation while maintaining relatively simple manufacturing processes.
2Reliability
If an integrated battery is used in the wearable device, then the device structure is compact, but safety risks increase due to inability to detach under threshold force
Solution Approach 1:
The detachment features are pre-configured with specific mechanical properties during manufacturing. The first detachment feature is designed to detach from the second detachment feature when a threshold force is applied, creating a predetermined safety mechanism. This preliminary configuration ensures that if excessive force is applied to the wearable device, the battery module will automatically detach, preventing damage to the user or device, thereby improving safety without significantly increasing overall device complexity.
3Ease of manufacture
If an integrated battery is used in the wearable device, then manufacturing assembly is complex, but battery disposal and replacement become difficult
Solution Approach 1:
The battery is extracted from the traditional integrated design and placed in a separate, removable module. The battery module can be easily detached from the device body through the detachment features and electrical contacts. This extraction allows users to easily replace or dispose of the battery without needing to disassemble other device components, significantly improving ease of repair and disposal while keeping the manufacturing process for each module relatively simple and independent.

AI summary
Methods, systems, and devices for operating a wearable device are described. A wearable device may include a first portion that has one or more electrical contacts and at least one sensor configured to measure one or more physiological parameters of a user. The first portion may also include one or more detachment features configured to detachably couple a removable battery with the first portion. The removal battery may be coupled with one or more electrical contacts for the removable battery. The removable battery may also be coupled with one or more counterpart detachment features that are configured to interface with the one or more detachment features of the first portion such that the one or more electrical contacts for the removable battery connect with the one or more electrical contacts of the first portion when the removable battery is detachably coupled with the first portion.
