Description

Instant body weight measurement system

The invention relates to a body weight measuring system, in particular to an instant body weight measuring system capable of monitoring body weight at any time.

Because of the busy work, modern people also have a lot of social entertainment. If they are neglected and self-controlled, their personal weight will gradually increase unconsciously, which will lead to morbid obesity and even other physical diseases.

The tool used by most people to measure their weight is based on the weight scale. However, the weight scale must be placed on a flat surface to measure, and the user cannot measure the weight of the individual. Therefore, how to remind people to pay attention to physical health in a busy social life has become one of the focuses of current attention.

For example, China's new publication No. M333559 "Weight Measuring Device" is mainly to combine a weight measuring device with the seat used by people every day, and use a pressure sensor to sense the user's seat when sitting in the seat. Based on the weight of the body weight, the user's weight is measured. However, because the seat is still placed in a specific place (such as an office, a home, etc.), when the user wants to measure the weight, it still needs to go to the seat to carry out, and the mobility is still insufficient.

Another example is China's Announcement No. 383152, "Radio Transmit and Receive Active Fluid Insole", which mainly includes an insole body, a fluid bladder, an outlet connection portion, a pressure sensor, a temperature sensor, and an emission. a circuit, and a receiving circuit. Wherein the insole body is provided with at least one fluid bladder filled with a fluid body, which may be a gas (such as air, nitrogen), a liquid (such as water or oil) or silicone, by a pressure sensor and a temperature sensor. Cooperating to sense the pressure value and the number of compressions of the fluid capsule of the insole body, and then calculate the weight of the user, the mileage of walking steps, the number of calories burned, and then transmitted by the transmitting circuit, and received by The circuit receives and displays it. However, this design causes an increase in the cost of the insole, and when the fluid is liquid, if the fluid capsule is inadvertently broken, the utility will be lost. In addition, because the fluid itself has fluidity, the user is likely to be unstable when stepping on the pedal, resulting in use. Safety is a concern.

Therefore, the object of the present invention is to provide an instant body weight measuring system which is placed in a shoe so that the user can easily monitor the weight through daily use of the electronic product as long as the user wears the shoe. Good self-health management.

Thus, the instant body weight measuring system of the present invention comprises an integrated weight measuring device and a mobile electronic device.

The body weight measuring device is configured to be disposed in a shoe, and includes a flexible substrate, a first pressure sensing unit, a second pressure sensing unit, a central processing unit, a first wireless communication unit, and a A power supply unit that supplies the power required to operate each unit. Among them, the first The pressure sensing unit is disposed on the flexible substrate and is configured to sense a pressure of a base between the first to fifth toe of the wearer. The second pressure sensing unit is disposed on the flexible substrate and is configured to sense the pressure of the wearer's heel portion. The central processing unit is electrically connected to the first pressure sensing unit and the second pressure sensing unit, and the central processing unit is externally disposed according to the first pressure sensing unit and the second pressure sensing unit. The area of the profile is preset to a base area value, a heel area value, and the wearer's plantar pressure is converted into a body weight value according to the following formula: [(the pressure from the first to the fifth toe base) The value is multiplied by the base area value + (the pressure value of the heel portion is multiplied by the heel area value)] multiplied by 2. The first wireless communication unit is electrically connected to the central processing unit and configured to wirelessly transmit the weight value signal processed by the central processing unit.

In addition, the mobile electronic device includes a second wireless communication unit for receiving the weight value signal sent by the first wireless communication unit, and a display unit for displaying the weight value signal received by the second wireless communication unit. .

The processing unit 24 can process the pressure signals sensed by the first pressure sensor 221 and the second pressure sensors 231 into a weight value signal. The central processing unit 24 converts the wearer's plantar pressure into a body weight value according to the following formula: [(the pressure value of the base A1 between the first to fifth 511 to the fifth toe 512 multiplied by the base A1 area value) + (The pressure value of the heel portion 513 is multiplied by the area value of the heel portion 513)] multiplied by 2. The pressure of the base A1 is an average value of the pressures sensed by the first pressure sensors 221 . The pressure value of the heel portion 513 is an average value of the pressures sensed by the second pressure sensors 231.

In detail, referring to Figure 4, and referring to Figures 2 and 3, according to the information on the distribution of plantar pressure provided by Prof. Abe Kaoru, Professor of the Department of Prosthetic and Limb Equipment, Niigata Medical and Welfare University, Japan, in the absence of heel height Next, 57% of the pressure is distributed at the heel portion 513, and another 43% of the pressure is distributed at the base A1 between the first to fifth 511 and the fifth toe 512. However, as the height of the heel increases, the pressure distribution also changes. The general habit of wearing shoes, the height of the heel is mostly 2 to 4 cm, for example, when the height of the heel 411 is 2 cm. 50% of the pressure is distributed in the heel portion 513 of the human body, and another 50% of the pressure is distributed at the base A1 between the first to fifth 511 and the fifth toe 512. When the height of the heel 411 is 4 cm, 43% of the pressure is distributed on the heel portion 513 of the human body, and 57% of the pressure is distributed at the base A1 between the first to fifth 511 and the fifth toe 512. If the height of the heel 411 is increased by 6 cm, 25% of the pressure is distributed in the heel portion 513 of the human body, and 75% of the pressure is distributed at the base A1 between the first to fifth 511 and the fifth toe 512. Even, the heel 411 is heightened to 10 cm, and only 10% of the pressure is distributed in the heel portion 513 of the human body, and 90% of the pressure is distributed at the base A1 between the first to fifth 511 and the fifth toe 512.
