    Ergonomic Design

    In the fourth stage of the ergonomic design the “division of labor between segments of the organism” is designed. On the basis of anthropometric and physiological and also information- and cognitionpsychological realizations, activity elements and working equipment are improved for the functions of energy and power generation and the functions of the information absorption, processing, and delivery. The model of user–computer interface, which is described in the following exemplifies the stage of ergonomic design. This model is based on the language model, which derives from Foley and van Dam (1982). The model supports the process of designing the user–computer interface and consists of four steps. 1. In the first step…

    Process of Work System Design

    The implementation of ergonomic insights in concrete solutions of work system design is carried out in different operational functions. The individual divisions approach their task of work system design with different areas of interest. Regarding the systematization of such design interests developed a conception from a personal view. He differentiates interests of preservation, interests of design, and interests of utilization of human work. In reference to the interest of preservation of the human work ability the occupational safety was developed, which in turn endues own systematic procedures, for example, the TOP model. Work technology is referred to, regarding the general interest of the function of work systems. The work technology…

    Working Equipment and Operating Resources

    A meaningful classification of technical systems, which are also called working equipment and operating resources can be considered in accordance on the basis of the system function and the system output. The categories “transformation,” “transport,” and “storage” can be differentiated regarding the system function. Transformation means that the outputs of a system are quantitatively and/or qualitatively different from the system inputs. Transport signifies that only the spatial and temporal coordinates between inputs and outputs change while the material, energetic, and informational attributes remain constant in quality and quantity. The function class “storage” is concerned; if only the temporal coordinates of the output differ from those of the input while all…

    Working Person (several dimensions of human work capacity)

    Referring to the working person, several dimensions of human work capacity can be distinguished theoretically, even if it is difficult to account for the differentiation in dimensions in a metrological way concerning the concrete application. These dimensions are called, on the one hand, ability and, on the other hand, willingness to perform. In regards to ability the characteristics, which cause the achievement structure of a working person are considered physiologically as achievement capacity of the organs and/or organ systems and psychologically as achievement potential of psychological functions and/or appropriate components. Willingness to performis determined physiologically by the excitation level of organs and/or organ systems in the psychological sense by achievement…

    Interaction of posture, forces and time

     “The safety of the body is ensured by considering its weakest link.”     It is important to remember that the interaction between posture, force and time may sometimes increase or decrease the total risk (increased probability and severity of injuries) considerably. It is for instance not necessarily true that lifting heavy weights is always a risk; this is acceptable as long as it is done infrequently (to ensure recovery) and with good posture.  In contrast, small, persistent loadings over a long time period can be much more harmful than they seem, because weak structures that are constantly nearing fatigue can “drag along” neighbouring body structures into compensating with muscular tension.…

    WHY DO I NEED TO KNOW THIS AS AN ENGINEER?

      From a physical point of view, having a basic understanding of the human body’s strengths, abilities, and limitations is an important basis for making well thought-out tweaks to the design of the workplace, in order to build work systems that are not a risk to huma health or performance. Knowing how your muscles, bones and joints work may seem like a far cry from your engineering work, but it will significantly help your understanding in later  chapters where physical loading and methods of ergonomics evaluation are  discussed. Another thing this chapter does, is to provide a limited description of anatomy and  physiology; it will not go into as much…

    Different engineering roles act on different types of knowledge

    Engineers may end up playing a variety of different (sometimes overlapping) roles in their professional career. Each with their distinct scope, system level and operational concerns – some switch between several of these throughout their working life, depending on how specialized their working role is and at what system level they are. Expected to address problem solving. For example, an engineer may act on a specialized, operative level with responsibility for a single  production line, which would require specific methods and  knowledge to optimize for human well-being and performance.  Other engineers end up at a management level, where they are  perhaps not served by  anatomical knowledge  and ergonomics evaluation methods,…

    What is ergonomics/human factors?

    For many people, the word ergonomic is associated primarily with comfy office chairs, the correct labeled “ergonomic”, like kitchenware, backpacks or gardening tools. The word itself comes from the Greek roots ergon (work)and nomos (laws)androughlytranslatesto“th scienceofwork”,focusingonhumanactivity. The purpose of production ergonomics It can be assumed that anyone in charge of a production system would want all of its sub-components to function together with as much ease and efficiency as possible. When part of that production system is human, the performance of the system as a whole may vary depending on the daily form of the human workers. Although humans have great potential to bring flexibility, innovation and problem-solving skills to…

    Technical Design

    The concept of supervisory control supplies basic design indications, referring to the degree of mechanization and automation. “The term supervisory control derives from the close analogy between a supervisor’s interaction with subordinate people in a human organization and a person’s interaction with intelligent automated subsystems”. A supervisor gives instructions to the subordinates who have to understand and transform them into detailed actions. The subordinates, again, present their results to the supervisor. The supervisor has to compare his goals — in analogy to the cybernetic system approach with the results presented by the subordinates. Then he has to decide on the further action to be taken. The same sort of interaction…

    Work Environment/Environmental Influences

      On the one hand, social and cultural factors, which affect the work system are assigned to the work environment. On the other hand, the term “environment” means the spatially surrounding fields, from which physical and chemical, and in addition, biological (e.g., bacteriological) influences affect humans and their physical ability. The physical –chemical work environment can be differentiated according to the kind of influences it has on the working person: Working materials Radiation Climate Noise and sound Mechanical vibrations Lighting On the basis of the fact that individual work environment factors rarely appear isolated, but in combination with each other a consideration of effects is only permissible for the entirety…
