Unformatted text preview: ASSOCIATE PROFESSOR DR. SITI ZAWIAH MD. DAWAL DEPT. OF ENGINEERING DESIGN AND MANUFACTURE UNIVERSITY OF MALAYA Anthropometry in Workstation Design A basic philosophy in ergonomics is to design workstations that are comfortable, convenient and productive to work at. Ideally workstations should be designed to fit both the body and the mind of the operator. Anthropometry is not only concern about appropriate working height but also about how the operator can easily access controls and input devices. Anthropometry Measurement of the human body Anthropometric information describes the dimensions of the human body, usually through the use of bony landmarks to which height, breadths, depths, distances, circumferences and curvatures are measured. Definition of Anthropometric Measures Anthropometry and its used Body size and proportion vary greatly between different population and racial groups- which designers must never lose sight of when designing for an international market. The importance of anthropometric considerations in design as follows: If a piece of equipment was designed to fit 90% of the male U.S. population, it would fit roughly 90% of Germans, 80% of Frenchmen, 65% of Italians, 45% of Japanese, 25% of Thais and 10% of Vietnamese. It is usually impracticable and expensive to design products individually to suit the requirements of every user. Mass-produced and designed to fit a wide range of users-the custom tailor, dressmaker, and cobbler are perhaps the only remaining examples of truly user- oriented designers in western industrial societies. Selection Vs Modification Assume a heavy box is to be moved from point A to point B. Realizing that people are vary, there are probably two basic strategy:- One alternative is to use selection, that is, from the population of workers select a strong persons.- This can be label as fit the person to the job Another alternative is job modification that is almost everyone can do it. This can be labeled as fit the job to the person or fitting the job to you. Given the decision to modify the job, one question is how much modification is necessary? Anthropometrics Design motto: Let the small person reach Let the large person fit The motto implies: ???? The anthropometric motto implies that reach distances should be designed for the small , 5 th percentile individual, whereas clearance dimensions should be designed for the large, 95 th percentile individual .
