Chapter 8 Problem Solving 8.1 Introduction  Problem solving requires many “tools” and skills. Make sure that you have them, or at least know where to find them and how to use them 8.2 Analytic and Creative Problem Solving    Two basic types of problem solving involved in design process: creative and analytic More students familiar with analytic, where there is one right answer Creative problem solving has no right answers 8.2 Analytic and Creative Problem Solving  Steps that typically help w/ problem solving      Make a model/figure Identify necessary, desired and given info Work backwards from answers Restate problem in one’s own words Check the solution and validate it 8.3 Analytic Problem Solving  Six steps to analytic problem solving:       Define the problem and create a problem statement Diagram and describe the problem Apply theory and any known equations Simplify assumptions Solve necessary problems Verify accuracy of answer to desired level 8.4 Creative Problem Solving       Use divergence and convergence to gather and analyze ideas. Divergence is brainstorming. Convergence is analyzing and evaluating the ideas, seeking out the best possible solutions What is wrong? What do we know? What is the real problem? What is the best solution? How do we implement the solution? Chapter 9 Visualization and Graphics 9.1-9.2 Visualization   Visualization is often used as a mode of communication between engineers Sketches, tables, graphs, computer generated drawings, blueprints are various ways in which engineers communicate via visual mediums 9.3 Sketching   Although most final drawings are computer generated, initial and freehand sketches are vital to the design process Freehand does not mean messy. Sketches should display an adequate amount of detail, and any pertinent notes/comments pertaining to the drawing  For instance, if a line is supposed to be straight, make it as straight as possible. A square will not pass for a circle. 9.7 Graphical Communication    Oblique and isometric drawings are 3D and general Orthographic drawings are 2D, more detailed, and often have dimensions for the part Object, Hidden, Centerline, and Construction are 4 common types of lines used in engineering graphics
