Philosophy of Engineering Design

• Abdulkadir Erden

INTRODUCTION

• The main philosophy behind all of the engineering
  and engineering design activities is to serve the
  people, society and mankind.
• This is why the engineering design is defined as
  an activity to satisfy a need. A need is real
  only if it is defined and identified by a human.
• Needs whether factual or fancied, moral or
  amoral, present or future, important or
  unimportant, have been and are the starting
  points in engineering design.

Engineers and designers are at service of the
mankind.
Needs whether factual or fancied, moral or
amoral, present or future, important or
unimportant, have been and are starting points in
engineering design.

Engineering design is a unique activity where a
physical design artifact is created from an
abstract need after human imagination. Although
the methodology is dependent on the particular
design need, all of the engineering design
activities have some common engineering features.

• Engineering design is densely creative at the
  beginning, and significance of creativity
  decreases towards the end of the process,
• Engineering design is iterative during the whole
  design process both at macro scale and at element
  scale,
• Engineering design is methodological (productive)
  towards the end of the design process.

5
ENGINEERING CREATIVITY

• is a process in which a set of machine
  components is selected to perform a predetermined
  function.
• is the act of finding possible sets of available
  machine elements to satisfy a pre-defined need.

6
Features...

• Designer's background education and experience
  are effective and significant factors in
  engineering creativity.
• End product of the engineering creativity is a
  description of a system, machine, tool, goods, or
  any object.
• It may be a free-hand sketch for engineering
  design.
• New ideas purge out in a short time usually after
  a relatively long period of creative thinking or
  mental focusing on the design need.

Among the many factors which effect creativity in
design are designers experience, designers
ability, economic factors, and designers own
preference.

features of engineering design creativity

• Engineering creativity is more methodological
  and systematic then the artistic creativity.
• Engineering creativity depends on the scope of
  the available elements (building stones) of a
  product. The larger the number of machine
  elements that a designer can access, it is more
  likely to develop the best possible design. This
  is the condition where mechatronic technology has
  actually started.
• Engineering creativity is largely dependent on
  the designers own educational background and own
  personal experience.
• Market conditions all alone may change the
  design product, and therefore the engineering
  creativity is dependent on the market conditions.
• Available technology is probably the most
  important factor in engineering design.

17
Level of technological development affects the
design products.
Mechanisms
Electronics
Software

Issues to remember in any design

• The stage and level of industrialization of the
  society is a factor in design.
• The social traditions.
• Sophistication and complexity of the design
  product.
• Intended lifetime.
• Economical conditions.
• Geographical and climatic conditions.

A product should be designed to function under
all of the possible severe environmental
conditions.
23
Remember also...

• 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.

24

• Engineering design is naturally an iterative
  process.

METHODOLOGICAL / PRODUCTIVE FEATURE of
ENGINEERING DESIGN

• Productivity is literary defined as efficiency in
  industrial production.
• Work breakdown of design project.
• Detail design computations.
• Parameter optimization of a developed system.
• Adapting the developed basic design for the
  particular conditions.
• Report writing for the formal presentation

MECHATRONICSAN ENGINEERING PHILOSOPHY

• Integration of
• Electronics and Software Technology into a
• Functional Mechanical Structure
• conceptual Integration of basic mechatronic
  components into a physical product

32
Why is different?

• 1) Tools for the mechatronic design may be
  different from tools of the conventional design.
• 2) Available components for a mechatronic design,
  both in variety and composition are more than the
  conventional design. This makes the conceptual
  design more flexible, but increases number of
  alternative design solutions to impractical high
  values.
