Here we emphasize the design of mechanical and structural precision machine components and their integration with sensor, actuator, and control systems to maximize performance. Design is a mixture of analysis and creative thought. Good designs are based on excellent concepts and properly designed details.

This module will expose readers to the fundamental elements of a good engineering design, and to the creative problem solving methods practiced by engineers.
Ask students if they remember the scientific method. Ask students to list the steps of the scientific method. Accept free responces from students. Relate scientific method to real world application of engineering.
Engineering design is the creative process of identifying needs and then devising a solution to fill those needs. This solution may be a product, a technique, a structure, a project, a method, or many other things depending on the problem. The general procedure for completing a good engineering design can be called the Engineering Method of Creat...
Evaluating the needs or identifying the problem is a very important step in finding a solution. An improper definition of the problem will cause the engineer to waste time or arrive at an incorrect solution. It is important that the stated needs be real needs. A great design may be worthless if it duplicates other known designs or doesn’t benefi...
After defining the problem, an engineer begins to gather all the information and data necessary to solve the problem. It could be physical measurements, maps, results of laboratory experiments, patents, results of opinion surveys, or any number of other types of information. Engineers should always try to build on what has already been done before...
There are several techniques to help a group or individual to produce original creative ideas. The development of these new ideas may come from creativity, a subconscious effort, or innovation, a conscious effort. Some techniques Wright (1) suggests that may aid a group or individual in obtaining a creative solution are brainstorming, checklists, ...
BRAINSTORMING RULES All ideas are encouraged. Record as many ideas as possible. Combine and improve ideas. Delay judgment and evaluation of ideas until end. popular technique for group problem solving is brainstorming. Typically, a brainstorming session consists of 6 to 12 people who spontaneously introduce ideas designed to solve a specific probl...
One of the simplest methods for generating new ideas is to make a checklist. The checklist encourages the user to examine various points, areas, and design possibilities. For example to improve a device, you may want a checklist like this: Ways the device could be put to other uses. Ways the device could be modified. Ways the device could be rear...
With attribute listing, all the major characteristics or attributes of a product, object, or idea are isolated and listed. Then, for each attribute, list ideas as to how each of the attributes could be changed. Again, as in brainstorming, all ideas are listed no matter how impractical. After all the ideas are listed, evaluate each idea bringing ...
The forced relationship technique takes a fixed element, such as the product or some idea related to the product, and forces it to take on the attributes of another unrelated element. This forms the basis of a free flowing list of associations from which hopefully new ideas will emerge. As before, judge the value of the ideas after the process is...
People sometimes stretch their minds by adopting different points of view. Imagine a similar problem located on a strange planet or in free fall. Try to identify with the stone that is to be crushed, or the fruit that is going to be peeled. Pretend that common materials or components are not available or that certain exceptional ones are. Try t...
Here are some specific actions and attitudes that can be employed to overcome obstacles to creative thinking:1 Avoid placing unnecessary constraints on the problem being solved. Search for different ways to view the problem, avoiding preconceived beliefs and stereotypical thinking. Recognize that there are non-engineering solutions to many problems...
For engineers to move from ideas to a preliminary design, they must sort through the possible solutions and determine which ones are unworkable and which might have promise. The promising ideas are then molded and worked into plans. Preliminary designs evolve through analysis and synthesis. Analysis is breaking apart the whole and studying its i...
There are many criteria that engineers use to evaluate the value of a solution or design, which may depend on the nature of the problem. If the solution involves a product, great importance may be placed on safety, cost, reliability, and consumer acceptability. Many designers use prototypes to test the operation of the design. The designer could ...
After selection of the preferred design, it must be communicated to those who must approve it, support it, and translate it into reality. This communication may take the form of an engineering report, or a set of plans and specifications. Plans and specifications are the engineer’s means of describing to a manufacturing division or to a contracto...
Engineers create detailed technical drawings that show what the design looks like, what parts are necessary, how to assemble it, and how to operate it once constructed. These graphical specifications are probably the most important type of documentation for engineering design problems. They communicate visually to the technical team what verbal c...
Memorandums, often called memos, are a brief and effective way to keep everyone involved aware of the design’s progress. Memos can be distributed to one person or to a list of people within the organization who have an interest in the subject. technical report is a much longer and complete record of the design process. It should include everythin...
At different stages during the design process an engineer may be called upon to give an oral progress report to the design team, the supervisor, or management and marketing people. The objectives of an oral presentation are the same for a written report: the engineer wants to communicate information and convince the audience. The methods used ho...
Since a design project is usually much more complicated than finishing physics homework, a complete solution will involve several steps or tasks. Some complex problems will require weeks or months to complete. The design problem solution needs to include a schedule or a plan of when to do the necessary tasks to complete the design. In a good sch...
The final stage of the design process is implementation, the process of producing or constructing a physical device, product, or system. Engineers must plan and oversee the production of the devices or products and supervise the construction of the engineered projects. Different engineers may, of course, be involved in this final phase. For the ...
Suggestions for brainstorming activity: Students do not write on their worksheet. Construct a concept map using the overhead transparency. Suggested questions for brainstorming: ♦ What do you think of when you hear the word “design”, “engineer”, etc.? ♦ Why would you need to engineer a design? ♦ In order to meet a need, what should you do or dev...

Engineering design is the iterative process of developing a system, component, or process that meets specific needs. By creatively applying engineering analysis and design within the constraints of real-world systems, engineers produce custom-made solutions to any problem.
In analyzing the methodology for discovering, deriving, formulating and validating design principles, the goal is to understand and advance the theoretical basis of design, the foundations of new tools and techniques, and the complex systems of the future.
