An Iot Based Schoolbag Overweight Detection System

The present invention relates to the school bags with a weight measuring mechanism which shows an indication of the bag's own weight without requiring the use of any external weight measurement thereof to prevent overburdening the student. The present system works on a piezoelectric material and shows signal in the form of light. The weight sensor is used to get the weight of material in school bag. After putting the stationary material in the bag, the weight sensor gets activated. If the weight of the bag exceeds the predetermine limit, the piezoelectric materials produce electric energy upon application of stress and generates the overweight signals in the form of light due to polarization effect. This suggests the student to reduce the material in the bag.

001] The present invention relates to the field of the bags. The invention more particularly relates to the school bags with a weight measuring mechanism which give an indication of the school bag's weight without requiring the use of any external weight measurement thereof to prevent overburdening the student.
BACKGROUND OF THE INVENTION
[002] The following description provides the information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] In societies where education is highly emphasized at an early age of a child, there is pressure for the children to perform well in school. This pressure creates the temptation for the children to fill their bags with as many books to cover as many topics as possible. School bags, when completely or substantially filled with books, can be very heavy. Often times, the load is too much for some children to handle. Because a child's body has not fully matured, carrying overly heavy bags consistently over a prolonged period can have detrimental effects on their bodies.
[004] As a rule of thumb, it has been stated that children should not carry more than 10% of their body weight. It appears that back ache and lumbar problems suffered by adults can, in some cases, be attributed to carrying heavy schoolbags and other loads as a child. Weighing a schoolbag by a parent or guardian on a domestic kitchen or bathroom scales is often not practicable. Neither is it practicable for schools to weigh the bags of all students; particularly since the allowable weight that may be carried is student specific, depending on the size and health of the student, as described hereinabove. Preferably schoolbags should be worn as backpacks, with the weight evenly distributed over both shoulders.
[005] Accordingly, on the basis of aforesaid facts, there remains a need in the prior art to provide a simple mechanism attached to the school bag which would quickly indicate the weight of the bag without having to rely on any other external device. Therefore, it would be useful and desirable to have a system, method, apparatus and interface to meet the above-mentioned needs.
SUMMARY OF THE PRESENT INVENTION
[006] The present invention provides the school bag with a weight measuring mechanism. The object of the present invention is to avoid the above-mentioned problems and to provide a school bag with a self-weighing mechanism which can indicate the total weight of the bag in the form of light by piezoelectric material, without requiring any other external instrument.
[007] The main aspect of the present invention is detecting the weight of school bag by a weight sensor and then signalling this in the form of light by piezoelectric material to the carrier of bag. The system is comprised of, but not limited to, a weight sensor that measures the weight of the bag, a piezoelectric material, an indicating light.
[008] Disclosed is a system that works on a piezoelectric material that shows signal in the form of light. The weight sensor is used to get the weight of material in school bag. Once the weight of the bag exceeds the limit the piezoelectric material get lighten by the weight.
[009] In this respect, before explaining at least one object of the invention in detail, it is to be understood that the invention is not limited in its application to the details of set of rules and to the arrangements of the various models set forth in the following description or illustrated in the drawings.

As used throughout this description, the word "may" is used in a permissive sense (i.e. meaning having the potential to), rather than the mandatory sense, (i.e. meaning must). Further, the words "a" or "an" mean "at least one” and the word “plurality” means “one or more” unless otherwise mentioned. Furthermore, the terminology and phraseology used herein is solely used for descriptive purposes and should not be construed as limiting in scope. Language such as "including," "comprising," "having," "containing," or "involving," and variations thereof, is intended to be broad and encompass the subject matter listed thereafter, equivalents, and additional subject matter not recited, and is not intended to exclude other additives, components, integers or steps.
