This study aims to develop a system for the prevention of diseases arising from non-compliance with the ergonomic rules. The significance of this topic is because students spend a lot of time at school, attending lessons and sections, and precisely in this adolescence age, the spine is during increased growth. If we allow the curvature of the spine, then there can be serious consequences for the body. Moreover, the office workers and drivers spend most of their time in a sitting position. Therefore, in order to study this problem, data was collected through interviews with a trauma doctor at a general children hospital and with a school pediatrician. Also, the student observed his classmates and within the walls of the school to study the problem. The author provides statistics on scoliosis in his own school, country and globally. The scientific novelty of the project lies in the fact that this system will preserve the health of the workplace without the influence of additional devices in many areas, preserving the health of the user. As a result, the Innovative ergonomic system (InErS) was developed, which is designed to prevent diseases that occur due to non-compliance with the ergonomics rules. We have proposed and designed the InErS system, which is a guarantee of prevention of diseases of the spine. This system will be used in the working environment in different organizations, and particularly in the educational institutions. We believe that this developed system is suitable to use, since it does not require additional devices from users, but it works in any kind of workplace.
