Abstract:
A notebook is an equipment with important role in various works such as printing document, making an account or recording data. In working with it, sometimes there must be work done together with books and documents on a lot of time when must be used. These affect parts of the body such as neck, back, shoulder, arm and wrists, make fatigue. These happenings are medically called office syndrome. So, the research aim is to designing equipment set or book holder for laying books, textbooks or documents. In addition, This equipment set could adjust the sight angle of the eyes, from the previous lying laterally on the table to be in the same plane as the eye screen.The equipment set would reduce the rate of looking up and down, which affected directly to the neck and back movement. This redesign equipment could put the working position and surrounding area where were suitable for the ergonomics principle. Accordingly, the project emphasized on the redesign of the equipment set for laying books, textbooks or documents, with the technique TRIZ in solving the problem of technical contradiction which occurred during the design. The result was to make prototypes to test the performance and functionality of the device. In conclusion, this device reduced fatigue and injury of the neck as well,and the movement of the body was decreased 23% of printing books and 27% of printing manuscripts. Then the ability to print was an increasing trend and the number of words typed per minute with an average was increased of 10%.
