Detachable Watch Body and Band Split Architecture
Solution Overview
Problem
Wearable devices, such as wristband systems, often present an encumbrance to users during activities like sleeping or sports, and they face challenges in power consumption and battery life due to continuous operation, as they typically operate without the ability to detach the watch body from the watch band.
Innovation Solution
A wristband system with a split architecture that allows the watch body and watch band to operate independently and communicate, featuring a detachable coupling mechanism that reduces encumbrance, enables independent power consumption modes, and offloads computing tasks from head-mounted displays to optimize power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the watch body is permanently attached to the watch band, then the device structure is simple and reliable, but the user experiences encumbrance during activities like sleeping or sports and cannot optimize power consumption
Solution Approach 1:
The wristband system is divided into two separable components: a watch body and a watch band. The coupling mechanism includes a coupling member on the watch band and a corresponding coupling mechanism on the watch body, allowing the user to detach the watch body from the watch band when needed for comfort during activities like sleeping or sports, while maintaining a integrated structure when worn
2Duration of action of stationary object
If the watch body is permanently attached to the watch band, then the device structure is simple, but the battery life is limited due to continuous operation
Solution Approach 1:
The system dynamically adjusts its operational state based on whether the watch body is coupled to the watch band. When detached, the watch body enters a low-power mode with reduced functionality, while essential functions on the watch band continue to operate. This dynamic power management extends battery life by avoiding continuous full-power operation
3Ease of operation
If the watch body is detached from the watch band, then user encumbrance is reduced, but the device loses integrated functionality and communication capability
Solution Approach 1:
Both the watch body and watch band are designed with independent functionality. The watch band can operate as a standalone device with its own sensors, display, and processing capabilities. The coupling mechanism includes electrical contacts that enable communication and data transfer when coupled, but the watch band maintains essential functions when detached, ensuring reliability in both coupled and uncoupled states

AI summary
Systems may include a watch band, a watch body comprising at least one image sensor configured to capture a wide-angle image, a coupling mechanism configured to detachably couple the watch body to the watch band, and at least one biometric sensor on at least one of the watch band or the watch body.
