Description

Technical field of the invention

The present invention relates to a mechanical wristwatch having a wristband equipped with electronic functions. The term mechanical wristwatch as used in this application comprises all types of mechanical wristwatches, in particular watches that need to be wound up manually and watches with automatic winding.
In particular, the wristband of the mechanical wristwatch in the present invention is equipped with medical and health related biosensors and electronic components such as heart rate monitor, blood glucose monitor, skin temperature sensor, skin conductance sensor and oximetry sensor. In addition, the wristband is also equipped with data processor together with electronic components and modules such as one or various antennas, a printed circuit substrate, an accelerator, a pedometer, a gyroscope, a magnetometer, a wireless communication transceiver such as a GPS receiver module, a Bluetooth module or a NFC module, a display and/or a voice modules, etc.

Background of the invention

A mechanical wristwatch uses a mechanical mechanism to measure the passage of time. As already mentioned, a mechanical wristwatch can either be a so called "automatic mechanical watch" or a "manual wind watch". An automatic mechanical watch is a mechanical watch with a self-winding mechanism whereas a manual or "manual wind" watch needs to be wound by hand, using the crown, usually every day, to operate continuously. Mechanical watches are driven by a spring (called mainspring). Its force is transmitted through a series of gears to power the balance wheel, a weighted wheel which oscillates back and forth at a constant rate. A device called an escapement releases the watch's wheels to move forward a small amount with each swing of the balance wheel, moving the watch's hands forward at a constant rate. This makes the 'ticking' sound characteristic of all mechanical watches.
An electronic wristwatch including quartz watch, as opposed to the mechanical wristwatch, functions electronically and uses battery to power the movement of the wristwatch. A variety of electronic components and modules are typically mounted in the central housing portion of the wristwatch. In some very few instances, these electronic components may be positioned on the wristband near to the central housing position but these electronic components require the central housing to assist in carrying out their functions. In such a watch or bracelet, the central housing portion acts as a single crucial and main component to store, process and display information.
In such a mechanical and electronic wristwatch, the role of the wristband is primarily to attach the wristwatch to the wrist of the user. The wristband more often than not is only viewed as a decorative item of the wristwatch without having a real functionally important role. Hence, it is not surprising that the housing of the wristwatch has been the focus throughout the history of the timepiece industry, while the wristband of the wristwatch has been ignored.
Moreover, users may also possess different electronic devices such as personal healthcare or medical devices like heart rate monitor, non-invasive blood glucose monitor and blood pressure device. These personal healthcare devices often exist individually and may be worn on a wrist of a user. However, it is not practical to wear several different wrist devices such as wristwatch, electronic device and personal healthcare device at the same time. Hence, it could potentially obstruct users to constantly monitoring their health status.
For these reasons, there remains a need in the art to find an alternative wristband which have enhanced functions while maintaining the elegant, high quality feature of the mechanical wristwatch as a whole.

Summary of the present invention

The inventors of the present invention have found out effective remedies for the above-discussed problems by introducing new concept of wristband as presently claimed. While maintaining the conventional housing of the high quality mechanical wristwatch, the smart wristband of the present invention is herewith disclosed which functions independently from the housing portion of the mechanical wristwatch. Moreover, electronic components, sensors, modules and wireless communication transceiver are embedded within the smart wristband of the present invention so that additional information can be provided to the users to enhance the overal quality of the mechanical wristwatch. Also, these components are preferably embedded within the wristband as such and are not provided in a separate housing.
The mechanical wristwatch equipped with wristband according to the present invention revolutionises conventional mechanical wristwatches by providing additional electronic features through its smart wristband, as well as positioning biosensors within the typically-ignored wristband, thus rendering its users for an enhanced experience and providing for the users value-added data which is collected from the electronic components and sensors, while not sacrificing the high quality of mechanical wristwatch core component (the housing portion) that is known for its expression of elegance of design, attention-to-detail in finishing and assembly, and the art of hand-tweaking movements for optimum performance. At the same time, the preferred embodiment with all additional components embedded within the wristband as such renders a practically and aesthetically better solution, given that no extra housings are required.

In particular, the wristband may comprise of a first, a second and/or a further wristband portion, wherein electronic components, sensors, modules, battery, antenna, wireless communication transceiver and other components are embedded within each of the aforementioned pocket portions, which is within the wristband portions. Said band portions may each function independently or may function together with another band portion through wireless communication to each other.
Specifically, in a first aspect of the invention, it relates to a mechanical wristwatch 100 comprising a housing 1 and a wristband 5, wherein the wristband is connected to the housing 1 for wearing the mechanical wristwatch 100 on a wrist of a user, wherein the housing 1 comprises a mechanical watch movement, characterised in that at least one of an input/ output module 19, 23, 24 and a data processor 50 are internally located within the wristband 5 such that the wristband 5 is able to: receiving data through the at least one input/ output module 19, 23, 24, processing data by the at least one data processor 50, and transmitting processed data through the at least one input/ output module 19, 23, 24, wherein the wristband 5 is functionally independent from the housing 1.
Conventionally, the housing of an electronic wristwatch serves to accommodate a variety of electronic components as the housing is relatively spacious compared to the wristband. However, in a mechanical wristwatch, the housing of the mechanical wristwatch is used to accommodate hundreds or thousands of mechanical components, hence it is not possible to accommodate further input/output module, data processor and other components in the housing.
For these reasons, the mechanical wristwatch having the wristband of the present invention is advantageous compared to the conventional, monotonous mechanical and electronic wristwatches, as wristband of the mechanical wristwatch is utilised to accommodate at least one of an input/output module and data processor. In other words, the wristband is totally independent from the housing portion of the wristwatch when executing its electronic and electrical functions. Also, in a preferred embodiment, no additional housing is required for the additional elements embedded into the wristband.
As illustrated in Figure 1, a mechanical wristwatch having the wristband according to the present invention is worn in a wrist of a user.

Generally, at least one of an input/output module and a data processor are suitable to be embedded within the wristband, for instance in the first band portion 16 and/or the second band portion. An additional pocket may also exist at the wristband which is suitable for embedding electronic components such as sensors, antennas, batteries, displays and other electronic components. The pocket may further be subdivided into several compartments.
Noteworthy, the first band portion 16 and the second band portion 18 may function individually. For example, a heart rate monitor sensor may be located in a first band portion 16. The first band portion 16 and the second portion may wireless communicate to each other in order to carry out a specific task together. For example, a biosensor may be located in the first band portion 16 while data being displayed at a display 34 that is located at the second band portion 18. This interaction can be achieved through a wireless communication. Furthermore, the wristband may be bendable, elastic stretchable or not stretchable. The wristband may also appear to be a rigid bracelet.
Figure 2 is a block diagram illustrating a mechanical wristwatch having the wristband according to one embodiment of the present invention. The electronic wristband of the present invention may comprise at least one of a input/ output module 23, 24 including a communication transceiver 19 such as a GPS receiver module 20, a Bluetooth module 21 and/or a NFC module 22; a pedometer 25, an antenna 26, a time module 27, a voice module 28, a power source such as a battery 29, a sensor module 30, a magnetometer 31, a gyroscope 32, an accelerometer 33, a display 34 and other components that are suitable to be embedded in a wristband. The aforementioned electronic components may interact with at least one data processor/electronic circuitry 30. In the data processor 50, it comprises a control unit 51, a data storage unit 52 and other functional units which allow for the data processor to operate.
The aforementioned electronic components are suitable to be embedded into the wristband according to the present invention and such electronic components could substantially enhance its users experience and satisfaction. For instance, accelerometer measures body movement to track steps and sleep patterns. Gyroscope measures rotations for a variety of purposes. They feed data into exercise-tracking algorithms, and can sense when the user turns his wrist to look at the watch face, thus waking up the display. Time module allows the electronic components including quartz to be used to act as a clock, a voice module is used to record, recognise voice so that voice-activation is possible and Magnetometer is used for improved accuracy in motion tracking. Barometric pressure sensor measures changes in altitude, which is relevant to any runner or cyclist who climbs hills. Skin temperature sensor measures the body temperature of the user. Heart rate monitor measures the heart rate of the user. Oximetry sensor measures blood oxygen which is suitable for reporting accurate pulse rates. Skin conductance sensor measures exertion levels, sweat level and also calorie-burn numbers.
A variety of healthcare information can also be provided by the wristband according to one embodiment of the present invention. In order to achieve this, different biosensor units may be embedded in the wristband. For instance, skin temperature sensor, oximetry sensor, skin conductance sensor, blood pressure sensor or heart rate sensor or other sensors which may be useful in providing health-related information to the user.
According to one embodiment of the present invention, the top surface of the wristband portion may be a display unit while at least one of an input/output module and a data processor can be embedded beneath the display.
