高さ調節など: BLE 対応のスマート デスクで健康を維持 Jun 05, 2023

Do you often feel exhausted all day sitting with a single rigid posture at work? I believe most of you may say Yes. No matter what you answer, it is absolutely uncomfortable for me to work a day sitting at a traditional desk.

Is there a perfect solution to solve that problem? Of course, the article will introduce how a smart height-adjustable desk embedded BLE technology to make you healthier and more comfortable.

Firstly, lets explore why you feel miserable when prolonged sitting at work. Here are the cost and hazards of prolonged sitting.

The Cost &Hazards of Prolonged Sitting

Unhealthy sitting habits such as bad sitting posture and prolonged sitting will cause terrifying harm to everyones body. They not only affect blood circulation but also cause a series of physical disturbances, such as poor eyesight, curved spine and heart disease, etc. Look at the picture below, you will know more about the hazards of prolonged sitting.

How To Ward off Such Habits Especially When You Work in the Office?

Frankly speaking, it is extremely hard if you keep using traditional desks, as they have shaped your sitting posture ever since. As we all know, traditional desks are usually fixed at a defined height and it is quite difficult for you to arbitrarily change them. These desks cannot be ergonomically adjusted to fit everyones body needs. But there comes good news-- a type of innovative desk will usher in a big change to that.

It is named a smart height-adjustable desk.

What Is A Smart Height-adjustable Desk Embedding BLE?

The height-adjustable desk is an ergonomic office desk solution. It allows you to work in a wide variety of postures, in which you can adjust the desk to a higher or lower position, to change the desks gradient via your back, or even to sit-stand alternately. Therefore, the smart desk helps you create a flexible workstation for a more energizing and productive working day. Only what you do is press a button or two to alter the intelligent desk as you like.

The trends of smart height-adjustable desks flashed from Europe and North America to the whole world. Those desks adopt such mechanisms as pneumatic, manual, or electric, etc. to actuate adjustment.

In the early stage, height-adjustable desks adopt a button or touch display for the user interface. It made the desk difficult to work if the input devices were damaged. Furthermore, the physical interface was designed at a designated part of the desk, making it clumsy and uni-functional, and impossible to meet diverse needs.

The introduction of Bluetooth Low Energy technology makes the desk smarter and more considerate ergonomically. With a BLE smart desk, you can select from different postures or modes from a designated App backed by a service library stored in a cloud-end server. Smartphones can also function as a user ID to access different patterns or services stored for particular phone users.

Shenzhen RF-star Technology Co., Ltd. supplies the BLE modules with enabling working logic for the whole solution to support such smart desks. The solution consists of an MCU, a wireless transmission unit (BLE device), a power supply unit, and a driving unit. In the following working diagram, the BLE module RSBRS02ABR is used as the wireless transmission unit, and it is connected to the MCU through a UART serial port. A mobile phone, tablet, or BLE remote controller is used to establish a connection with the BLE module, and commands are sent to the MCU of the desk, thus controlling the driving circuit to complete the lifting function of the desk. See details in Figure 2.

The BLE communication mentioned above is in a peer-to-peer mode that can be widely used in homes and offices. However, the application is not popular in most schools because it is not practical for students to carry mobile devices, and also it is clumsy to have teachers adjust the desks of all students one by one. As a result, a BLE remote controller comes to the public. Using a BLE remote controller can massively customize all smart desks simultaneously.

Now, BLE smart desks are popular in a wide range of scenarios.
