    12. Abdulkadir Erden 12/62 Design Activity ... is defined, in general, as the planning and realization of a creative strategy to accomplish a physical, mental, moral or artistic task or to satisfy a real need. This is engineering!..

    13. Abdulkadir Erden 13/62 Purpose of Design The purpose of design is defined [Mostow, 1985] as the construction of a structure (artifact) description that; Satisfies a given (probably informal) functional specification, Conforms to the limitations of the target medium, Meets implicit or explicit requirements on performance (time, space, power, cost etc.) and structure (style, simplicity etc.), Satisfies restrictions on the design process itself.

    14. Abdulkadir Erden 14/62 Design activities Design activities include Creativity, Decision-making, Modeling.

    21. Abdulkadir Erden 21/62 C. Ruiz and F. Koenigsberger The complete intellectual process from the conception of an idea based on inspiration, knowledge and experience to its final technical and commercial realization.

    22. Abdulkadir Erden 22/62 J. R. Dixon Science-based problem solving with social-human awareness, ... a high level intellectual activity.

    24. Abdulkadir Erden 24/62 W. H. Middendorf The activity wherein various techniques and scientific principles, are employed to make decisions regarding the selection of materials and the placement of these materials to form a system or device, which satisfies a set of specified and implied requirements.

    25. Abdulkadir Erden 25/62 A. D. Deutschman et al. The mechanism whereby a requirement is converted to a meaningful and functional plan. The formulation into a satisfactorily functioning device that satisfies the original need.

    26. Abdulkadir Erden 26/62 J. B. Reswick The essential purpose of engineering.

    27. Abdulkadir Erden 27/62 A B. Rosenstein and J. M. English An iterative decision making process for developing engineering system or devices whereby resources are optimally converted into desired ends.

    29. Abdulkadir Erden 29/62 TYPES of ENGINEERING DESIGN

    30. Abdulkadir Erden 30/62 Pahl and Beitz, 1988 Original design that involves elaborating an original solution principle for a system with the same task, a similar task or a new task. This may be the case of using a four-bar mechanism in the development of a walking machine. Adaptive design, which involves adapting a known solution principle to a changing task. Example: Design of a new gearbox, based on the known gear trains. Variant design, which involves varying the size and/or arrangement of certain aspects of the chosen system, while the function and solution of the system remain, unchanged. Example: Belt Conveyor design; Size of drum and belt width can be computed for a given loading with no change on the design configuration.

    31. Abdulkadir Erden 31/62 Dieter, 1991 One-of-a-kind design; Design of special purpose machines, Prototype machines, Design for mass production; Design of washing machine, Large, expensive system design; Design of a production line, Design to code; Shaft design, Boiler design.

    32. Abdulkadir Erden 32/62 Ullman, 1992 Selection design involves choosing one item from a list of similar items; Selection of bearing for a shaft. Configuration design in which all the components have been designed and the problem is how to assemble them into the complete product; Plant design, Conveyor layout design Parametric design involves finding values for the variables or parameters that characterize the object being studied; Conveyor design, Crane design. Original design is the development of a process, component or assembly not previously existing; Design of a machine with a specific purpose. Others (such as redesign, routine design)

    33. Abdulkadir Erden 33/62 Duffey & Dixon,1990 Functional design, Phenomenological design, Embodiment design, Attribute or configuration design, Parametric design.

    34. Abdulkadir Erden 34/62 DEFINITIONS FOR MECHANICAL ENGINEERING DESIGN OR MACHINE DESIGN

    35. Abdulkadir Erden 35/62 Machine Design ... is described as a creative thinking, planning and synthesis supported by analyses in order to produce a machine or system that will accomplish a predefined physical work. Besides, having the properties of the general design concept, an important additional characteristic of the machine design therefore is that, the artifact to be designed should have a certain functionality in terms of physical work.

    36. Abdulkadir Erden 36/62 Machine Design ... is defined as the transformation of parameters influencing a physical process into concrete machine components,

    37. Abdulkadir Erden 37/62 R. C. Johnson The process of creating and selecting configurations, shapes, materials, and dimensions for something which is physical in nature.

    38. Abdulkadir Erden 38/62 W. Rodenacker The transformation of the parameters influencing physical process into concrete machine components.

    39. Abdulkadir Erden 39/62 P. Orlov To abstain from blindly copying the existing prototypes and to design meaningfully, selecting from the entire store of the design solutions offered by the present day mechanical engineering the ones that are most suitable under given conditions. To be able to combine various solutions and find new, better ones, i.e. display initiative and put vim in the work. To continually improve the machines characteristics and to contribute to the progress in the given branch of mechanical engineering. To follow the dynamic development of the industry and devise versatile machines of long life amenable to further modernization and capable of meeting the every growing demands of the national economy without running the risks of obsolescent for a long time to came.

    40. Abdulkadir Erden 40/62 J. P. Vidosic The formulation of a plan for a mechanism or device capable of transmitting forces and motions, and doing work or accomplishing a specific function that must be done to satisfy a human need as economically as possible. The formulation of plans to satisfy human needs using the disciplines-engineering, sciences, techniques, and other mental processes-that are studied by mechanical engineers.

    41. Abdulkadir Erden 41/62 E. Parr The application of many of the principles of science and technology in the creation of a product and the consideration of the various factors that effect its production and use.

    42. Abdulkadir Erden 42/62 MACHINE DESIGN = MACHINE + ENGINEERING + DESIGN

    54. Abdulkadir Erden 54/62 Creativity Among the many factors which effect creativity in design are; designers experience, designers ability, economic factors, and designers own preference.

    55. Abdulkadir Erden 55/62

    56. Abdulkadir Erden 56/62 A product should be designed to function under all of the possible severe environmental conditions.

    57. Abdulkadir Erden 57/62 Remember The stage and level of industrialization of the society is a factor in design, The social traditions cannot be overcome easily, Sophistication and complexity of the design product is to be determined by the user, Economical conditions, Geographical and climatic conditions.

    58. Abdulkadir Erden 58/62 Limitations of Design Design should not violate scientific rules, Design should be economical, Design should be compatible to psychology and ergonomics, Design must satisfy requirements stated in standards, laws, regulations, Level of education and capabilities of the user, Production facilities.

    59. Abdulkadir Erden 59/62 Philosophy of Design

    60. Abdulkadir Erden 60/62 to reach a perfect level ...
