Bathroom Scales Accurately Position Your Center Of Gravity

- Dec 15, 2019-

The bathroom scale includes a base portion placed on the base, a support surface on which the user stands, a display showing the weight of the user, and a sensor element that senses the weight of the user.

Background technique:

Scales, especially bathroom scales, are known to have countless different types. The scale is mainly mechanical, which simulates the user's weight, or digital, and the number shows the user's weight.

The support surface of the scale is flat compared to the base on which the scale is located. When the person weighing himself is standing on the scale, there is no indication of where the person is standing. This makes it difficult for the weighed person to accurately position themselves and their own center of gravity, such as the weight sensing element away from the scale towards the edge or corner of the scale. Inaccurate positioning of the user's center of gravity prevents the scale from displaying accurate measurements.

Digital scales show that measurement results are usually more accurate than mechanical scales. If the measurement is displayed with an accuracy of ten thousandths of an inch, the inaccurate positioning of the user's center of gravity can produce a difference from the displayed measurement corresponding to several tenths of a thousandth. This is not satisfactory because the goal is to get an accurate measurement every time the user uses the scale.

The bathroom scale device, in addition to the weighing function, can also measure the body fatness of the person being weighed. The latter function requires better electrical contact between the scale support surface and the user's foot. Finally, the support surface has a bowl-shaped upwardly convex arched central region, i.e., a predominantly rotationally symmetric arched structure, and a peripheral portion of the planar edge portion adjacent thereto. This arcuate structure is so small that it can only make electrical contact when it is at least partially under the user's arch.

The bowl or part of the peripheral central area has no corrective effect on the position assumed by the scale user, especially in the vicinity of the bowl's axis of symmetry.
