Abstract

This invention discloses a method for detecting and adjusting the stance of a body fat scale. The control method includes: S1 When no one is detected standing on the scale, the main control component controls the display screen to output a prompt indicating that the user is standing on the corresponding electrode group. S2 When someone is detected standing, it is determined whether both sides of the foot position detection point group have detected the forefoot and heel, and whether the middle position detection point group has been triggered. S3 When both sides of the foot position detection point group have detected the forefoot and heel, and the middle position detection point group has not been triggered, a correct stance prompt is displayed. S4 When at least one side of the foot position detection point group has not detected the forefoot or heel, or the middle position detection point group has detected the forefoot or heel, a corresponding stance adjustment prompt is displayed, and the process returns to S2. This method guides the user to stand correctly on the scale so that the forefoot contacts the corresponding electrode, allowing the body impedance to be detected only after confirming the correct stance, thereby improving the accuracy of the measurement.

Description

[Technical Field]

[0001] This invention relates to a method for detecting and adjusting the position of a body fat scale. [Background Technology]

[0002] Currently, most body fat scales on the market use electrode pads or ITO glass as the body fat measuring electrodes. Users need to stand barefoot on four electrode pads during the measurement, with the left ball of the foot, left heel, right ball of the foot, and right heel in contact with the upper left, lower left, upper right, and lower right electrodes, respectively. However, due to variations in electrode shape, foot size, and standing posture, users may experience misalignment when standing for the measurement, causing some feet / heels to not contact the electrodes. This affects the accuracy of body impedance measurements and leads to inaccurate body fat measurements. [Summary of the Invention]

[0003] This invention overcomes the shortcomings of the prior art and provides a method for detecting and adjusting body fat scale positions.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A method for detecting and adjusting body fat scale positions, characterized by: a scale body; foot contact electrode groups on the left and right sides of the upper side of the scale body; a central position detection point group located in the middle between the two foot contact electrode groups on the upper side of the scale body; foot position detection point groups located near the foot contact electrode groups on the upper side of the scale body between the foot contact electrode groups and the central position detection point group; a display screen located at the front of the upper side of the scale body; and a main control component inside the scale body connected to the two foot contact electrode groups, the central position detection point group, the two foot position detection point groups, and the display screen. The control method includes:

[0006] S1. When it is detected that no one is standing on the scale, the main control component controls the display screen to output a prompt that both feet are standing on the sides of the electrode group.

[0007] S2. When a person is detected standing on the scale, the main control component determines whether the foot position detection point group on both sides has detected the forefoot and heel, and whether the middle position detection point group has been triggered.

[0008] S3. When both feet position detection point groups detect the forefoot and heel, and the middle position detection point group is not triggered, the main control component controls the display screen to show a correct position prompt.

[0009] S4. When at least one foot position detection point group fails to detect the forefoot or heel, or the middle position detection point group detects the forefoot or heel, the main control component controls the display screen to show the corresponding position adjustment prompt and returns to S2.

[0010] The body fat scale positioning detection and adjustment prompt method described above is characterized in that: the positioning adjustment prompt in S4 includes...

[0011] When the foot position detection point group on one side detects the heel but not the forefoot, and the middle position detection point group is not triggered, the display screen shows a position adjustment prompt for the corresponding foot to move forward.

[0012] When the foot position detection point group on one side detects the forefoot but not the heel, and the middle position detection point group is not triggered, the display screen shows a position adjustment prompt that the corresponding foot should move backward.

[0013] When the foot position detection point group on one side detects the forefoot and heel, and the foot position detection point group on the middle side detects the forefoot and / or heel, the display screen shows a position adjustment prompt indicating that the corresponding foot should move outward.

[0014] When the foot position detection point group on one side fails to detect the forefoot and heel, and the middle position detection point group fails to detect the forefoot and heel, the display screen will show a position adjustment prompt indicating that the corresponding foot should move inward.

[0015] When the foot position detection point group on one side detects the heel but not the forefoot, and the middle position detection point group detects the forefoot but not the heel, the display screen shows a position adjustment prompt that the forefoot on the corresponding side should be rotated outward.

[0016] When the foot position detection point group on one side detects the heel but not the forefoot, and the middle position detection point group does not detect the forefoot or heel, the display screen shows a position adjustment prompt that the forefoot on the corresponding side should be rotated inward.

[0017] When the foot position detection point group on one side detects the forefoot but not the heel, and the middle position detection point group does not detect the forefoot but detects the heel, the display screen shows a position adjustment prompt that the heel on the corresponding side should be rotated outward.

[0018] When the foot position detection point group on one side detects the forefoot but not the heel, and the middle position detection point group does not detect either the forefoot or the heel, the display screen shows a position adjustment prompt indicating that the heel on the corresponding side should rotate inward.

[0019] The body fat scale positioning detection and adjustment prompt method described above is characterized in that: the foot contact electrode group includes a forefoot electrode disposed on the front side of the upper side of the scale body for contacting the forefoot, and a heel electrode disposed on the rear side of the upper side of the scale body for contacting the heel.

[0020] The body fat scale positioning detection and adjustment prompt method described above is characterized in that: the foot positioning detection point group includes a forefoot positioning detection point set on the upper side of the scale body near the forefoot electrode, and a heel positioning detection point set on the upper side of the scale body near the heel electrode.

[0021] The body fat scale positioning detection and adjustment prompt method described above is characterized in that: the forefoot electrode and the heel electrode are both arc-shaped electrodes and are respectively located at the four corners of the upper side of the scale body; the forefoot positioning detection point and the heel positioning detection point are respectively located in the inner recess of the arc-shaped forefoot electrode and the arc-shaped heel electrode.

[0022] The body fat scale positioning detection and adjustment prompt method described above is characterized in that: the central positioning detection point group includes a central positioning detection point group for the forefoot located on the front side of the central position of the scale body, and a central positioning detection point group for the heel located on the rear side of the central position of the scale body.

[0023] The body fat scale positioning detection and adjustment prompt method described above is characterized in that: the forefoot mid-position detection point group includes a first forefoot mid-position detection point and a second forefoot mid-position detection point set vertically, and the heel mid-position detection point group includes a first heel mid-position detection point and a second heel mid-position detection point set vertically.

[0024] The body fat scale positioning detection and adjustment prompt method described above is characterized in that: the forefoot positioning detection point is set between the first forefoot mid-position detection point and the second forefoot mid-position detection point, close to the forefoot electrode position; and the heel positioning detection point is set between the second forefoot mid-position detection point and the first heel mid-position detection point, close to the heel electrode position.

[0026] The body fat scale positioning detection and adjustment prompt method described above is characterized in that: the display screen is set between the forefoot electrodes on both sides, and the positioning adjustment prompt displayed on the display screen is a cross-shaped mark composed of eight arrows, with an OK mark set at the convergence point of each arrow.

[0027] The beneficial effects of this invention are:

[0028] This invention features foot positioning detection point groups on both sides of the scale body to detect whether the feet are properly positioned, and a central positioning detection point group in the middle to detect whether there is an improper foot positioning or deviation. The main control component determines whether there is a standing deviation on both sides of the feet based on the detection signals from the foot positioning detection point group and the central positioning detection point group. Based on the detection signals, the display screen prompts the user to adjust their foot positioning so that both feet are in contact with the corresponding lipid measurement electrodes. This guides the user to stand correctly on the scale body so that their feet are in contact with the corresponding electrode plates. After confirming that the positioning is correct, the human body impedance is measured, thereby improving the accuracy of the measurement values. [Image Description]

[0031] Figure 3 This diagram illustrates the foot size and standing posture of different users. [Detailed Implementation]

[0032] The technical solutions in the embodiments of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0034] A method for detecting and adjusting body fat scale positioning, such as... Figure 1 As shown, the system includes a scale body 1. Foot contact electrode groups 2 are respectively located on the left and right sides of the upper side of the scale body 1. A central position detection point group 3 is located in the middle of the upper side of the scale body 1 between the two foot contact electrode groups 2. Foot position detection point groups 4 are located on the upper side of the scale body 1 near the foot contact electrode groups 2, between the foot contact electrode groups 2 and the central position detection point group 3. A display screen 5 is located at the front of the upper side of the scale body 1. A main control component is installed inside the scale body 1, which is connected to the two foot contact electrode groups 2, the central position detection point group 3, the two foot position detection point groups 4, and the display screen 5. The control method includes...

[0035] S1. When the weighing sensor of the body fat scale detects that no one is standing on the scale body 1, the main control component controls the display screen 5 to output a prompt that both feet are standing on the two sides of the foot contact electrode group 2.

[0036] S2. When a person is detected standing on the scale body 1, the main control component determines whether the foot position detection point group 4 on both sides has detected the forefoot and heel, and whether the middle position detection point group 3 has been triggered.

[0037] S3. When both sides of the foot position detection point group 4 detect the forefoot and heel, and the middle position detection point group 3 is not triggered, the main control component controls the display screen 5 to display a correct position prompt.

[0038] S4. When at least one foot position detection point group 4 fails to detect the forefoot or heel, or the middle position detection point group 3 detects the forefoot or heel, the main control component controls the display screen 5 to display the corresponding position adjustment prompt and returns to S2.

[0039] The main control component determines whether there is a standing deviation on both sides of the feet by detecting the signals from the foot position detection point group 4 and the middle position detection point group 3. Based on the detection signals, it prompts the feet to adjust their standing position through the display 5, guiding both sides of the feet to contact the corresponding fat measurement electrodes. This guides the user to stand correctly on the scale and detects human body impedance only after confirming that the standing position is correct, thereby improving the accuracy of the measurement values.

[0040] In this case, if Figure 2 As shown, the positioning adjustment prompts displayed on screen 5 are a cross-shaped symbol 51 composed of eight arrows, with an OK mark at the convergence point of each arrow. In this case, screen 5 displays two cross-shaped symbols 51; the left cross-shaped symbol 51 indicates the adjustment direction of the left foot, and the right cross-shaped symbol 51 indicates the adjustment direction of the right foot.

[0041] When the following occurs Figure 3 When a foot position deviation occurs due to differences in foot size and posture among users, as shown in the diagram, display screen 5 will show corresponding foot position adjustment prompts. Specifically, the foot position adjustment prompts in S4 include...

[0042] When the foot position detection point group 4 on one side detects the heel but not the forefoot, and the middle position detection point group 3 is not triggered, the display screen 5 displays a position adjustment prompt for the corresponding foot to move forward, that is, the upper side of the cross-shaped mark 51 on the corresponding side illuminates towards the arrow.

[0043] When the foot position detection point group 4 on one side detects the forefoot but not the heel, and the middle position detection point group 3 is not triggered, the display screen 5 displays a position adjustment prompt for the corresponding foot to move backward, that is, the lower side of the cross-shaped mark 51 on the corresponding side illuminates towards the arrow.

[0044] When the foot position detection point group 4 on one side detects the forefoot and heel, and the foot position detection point group 3 in the middle detects the forefoot and / or heel, the display screen 5 displays a position adjustment prompt indicating that the corresponding foot is moving outward. That is, when the foot position deviation occurs on the left side, the left-side arrow of the cross-shaped mark 51 on the left side illuminates as a prompt, and when the foot position deviation occurs on the right side, the right-side arrow of the cross-shaped mark 51 on the right side illuminates as a prompt.

[0045] When the foot position detection point group 4 on one side fails to detect the forefoot and heel, and the foot position detection point group 3 in the middle fails to detect the forefoot and heel, the display screen 5 displays a position adjustment prompt indicating that the corresponding foot should move inward. That is, when the foot deviation occurs on the left side, the right side of the cross-shaped mark 51 on the left side illuminates the arrow pointing to it, and when the foot deviation occurs on the right side, the left side of the cross-shaped mark 51 on the right side illuminates the arrow pointing to it.

[0046] When the foot position detection point group 4 on one side detects the heel but not the forefoot, and the foot position detection point group 3 in the middle detects the forefoot but not the heel, the display screen 5 displays a position adjustment prompt that the forefoot on the corresponding side rotates outward. That is, when the standing deviation occurs on the left foot, the upper left side of the cross-shaped mark 51 on the left illuminates towards the arrow, and when the standing deviation occurs on the right foot, the upper right side of the cross-shaped mark 51 on the right illuminates towards the arrow.

[0047] When the foot position detection point group 4 on one side detects the heel but not the forefoot, and the middle position detection point group 3 does not detect the forefoot or heel, the display screen 5 displays a position adjustment prompt that the forefoot on the corresponding side rotates inward. That is, when the standing deviation occurs on the left foot, the upper right side of the cross-shaped mark 51 on the left illuminates towards the arrow, and when the standing deviation occurs on the right foot, the upper left side of the cross-shaped mark 51 on the right illuminates towards the arrow.

[0048] When the foot position detection point group 4 on one side detects the forefoot but not the heel, and the middle position detection point group 3 does not detect the forefoot but detects the heel, the display screen 5 displays a position adjustment prompt that the heel on the corresponding side rotates outward. That is, when the standing deviation occurs on the left foot, the lower left side of the cross-shaped mark 51 on the left illuminates towards the arrow, and when the standing deviation occurs on the right foot, the lower right side of the cross-shaped mark 51 on the right illuminates towards the arrow.

[0049] When the foot position detection point group 4 on one side detects the forefoot but not the heel, and the middle position detection point group 3 does not detect the forefoot or heel, the display screen 5 displays a position adjustment prompt indicating that the heel on the corresponding side is turning inward. That is, when the standing deviation occurs on the left foot, the lower right side of the cross-shaped mark 51 on the left illuminates towards the arrow, and when the standing deviation occurs on the right foot, the lower left side of the cross-shaped mark 51 on the right illuminates towards the arrow.

[0050] When both sides of the foot positioning detection point group 4 detect the forefoot and heel, and the middle positioning detection point group 3 is not triggered, the OK indicator set at the confluence point of the arrows of the cross-shaped mark 51 illuminates, indicating that the stance is correct. During the foot adjustment process, the arrows in multiple directions of the cross-shaped mark 51 can also illuminate simultaneously to provide multi-directional foot adjustment prompts.

[0051] like Figure 1 As shown, the foot contact electrode group 2 includes a forefoot electrode 21 disposed on the front side of the upper side of the scale body 1 for contact with the forefoot, and a heel electrode 22 disposed on the rear side of the upper side of the scale body 1 for contact with the heel; the foot position detection point group 4 includes a forefoot position detection point 41 disposed on the upper side of the scale body 1 near the forefoot electrode 21, and a heel position detection point 42 disposed on the upper side of the scale body 1 near the heel electrode 22; the forefoot electrode 21 and the heel electrode 22 are both arc-shaped electrodes (in one embodiment) and are respectively disposed at the four corners of the upper side of the scale body 1. The forefoot position detection point 41 and the heel position detection point 42 are respectively disposed in the inner recess of the arc-shaped forefoot electrode and the arc-shaped heel electrode, ensuring that the forefoot and heel of the corresponding foot are in contact with the forefoot electrode 21 and the heel electrode 22 on the corresponding side, thereby improving the detection accuracy of each position detection point.

[0052] like Figure 1As shown, the central foot position detection point group 3 includes a forefoot mid-foot position detection point group 31 located on the front side of the central position of the scale body 1, and a heel mid-foot position detection point group 32 located on the rear side of the central position of the scale body 1; the forefoot mid-foot position detection point group 31 includes a first forefoot mid-foot position detection point 311 and a second forefoot mid-foot position detection point 312 arranged vertically, and the heel mid-foot position detection point group 32 includes a first heel mid-foot position detection point 321 and a second heel mid-foot position detection point 322 arranged vertically; the forefoot position detection point 41 is set at... The first forefoot mid-position detection point 311 is located between the second forefoot mid-position detection point 312 and near the forefoot electrode 21. The heel position detection point 42 is located between the second forefoot mid-position detection point 312 and the first heel mid-position detection point 321 and near the heel electrode 22. The second heel mid-position detection point 322 is located between the two heel electrodes 22, ensuring that the forefoot and heel of the corresponding foot are in contact with the corresponding forefoot electrode 21 and heel electrode 22, respectively, thereby improving the detection accuracy of each position detection point.

[0053] like Figure 1 As shown, the display screen 5 is positioned between the forefoot electrodes 21 on both sides, making it convenient for users to view the prompts displayed on the display screen 5.
