In recent years, wearable devices such as smartwatches and fitness bands have rapidly developed in the field of health monitoring, with features like heart rate, blood oxygen, and sleep monitoring becoming almost standard. However, a persistent issue that troubles users has emerged:Sleeping with these “high-tech” devices is truly uncomfortable! Imagine being jolted awake at night by a hard object on your wrist, or waking up in the morning to find a clear imprint of the dial on your wrist—such an experience is hardly pleasant.
What complicates matters further is: to obtain complete sleep data, one must endure this discomfort; yet, removing the device for a good night’s sleep renders health monitoring meaningless. This is truly a dilemma!
The root of the problem lies in the traditional all-in-one design of smartwatches. The hard dial and heavy sensor module must be fixedly connected to the strap, resulting in a noticeable foreign body sensation during wear. This design flaw becomes even more pronounced in a sleep scenario, which requires complete relaxation.
The crux of the issue is precisely the traditional smartwatches’ all-in-one design: the hard dial and heavy sensor module must be tightly bound to the strap. This structure creates a “hard lump” on the wrist, leading to an inescapableforeign body sensation. Especially in the sleep scenario, which requires complete relaxation, this design flaw is laid bare—it is fundamentally at odds with comfortable sleep.
However, a recent patent from Vivo (CN119700051A) paints a different picture: a detachable structure. It cleverly utilizes magnetic positioning and sliding limits in its mechanical design, allowing for quick detachment of the watch dial from the strap. More importantly, it integrates the core health monitoring module (such as heart rate and blood oxygen sensors) directly into the soft inner side of the strap, while ensuring stable data transmission between the dial and the strap.
What does this mean? When sleeping, you can simply remove the hard dial, leaving a soft, unobtrusive strap with integrated sensors on your wrist. Monitoring continues accurately, but your wrist experiences an unprecedented sense of liberation—turning over is unimpeded, and waking up leaves no marks.
The patent summary indicates: this application discloses a wearable device, belonging to the field of wearable device technology. The wearable device includes a wearing body and a device body, where the wearing body is equipped with a detection module, which communicates with the device body. One of the wearing body and device body is provided with a limit groove, while the other has a limit structure, with the limit groove extending along the edge of the device body, and the limit structure extending into the limit groove. One of the wearing body and device body also has a positioning groove, while the other has a movable positioning piece, with the positioning groove and positioning piece being positioned and matched. In the case where the positioning piece is detached from the positioning groove, the limit structure and limit groove slide together, and the limit structure can be detached from the limit groove to separate the wearing body and device body.
1. Detection module retained in the strap: Heart rate, blood oxygen, and other sensors are placed on the strap, meaning that even when the dial is removed, the strap still carries sensors that can directly contact the skin to collect physiological data.
2. Independent communication connection: The detection module maintains communication with the device body (such as the dial) via wireless technology (like Bluetooth or WiFi) or wired connection. After separation, the strap can wirelessly transmit data in real-time to the dial or other terminals (like a smartphone), ensuring continuity of monitoring.
