PROBLEMA: Discrepanciaentrelo real y lo o: Intro6 Design and AnalysisWhich of the following is design and which is analysis? that the customer wishes to electric motor to a device, select appropriate motor, pulleys and necessary an electric motor, we determine the efficiency of the motor by conducting load what is desired of a the solution to a design o: Intro7 Design: DefinitionSet of decision making processes and activitiesto determine the form of an object, given the customer s desired function. The crux of the design process is creating a satisfactory solution to a It is what engineering is all about Using knowledge and know-how to achieve a desired outcome.

4 Howdo design decisions change overtime? Is therea logical grouping of decisions?Dise o: Intro10 Example: Stopa spinning shaftEarly in the design process, we decide upon the specifics of the functionto be performed: Decide upona satisfactory rate of deceleration Determine the length of the shaft Determine where it is supported Determine what actuating energy is available Decide toreverse engineer an existing product Choose to research brakesin the libraryFormulationPhaseDise o: Intro11 Example: Decisions relating to concept?Decide physical principles that will perform the friction( drum brake, disk/caliper) magnetic fields( inversemotor) friction( fan blades) Assume wedecide on surface friction Concept Design PhaseDise o: Intro12 Example: Decisions on configuring productsand new components?

5 Decide upon product components & how they are arranged. Decide upon part features & how they are arranged. Product configuration: Disk/caliper, or drum, or band brake Location on shaft (right. left, middle) (Assume we decide on a disk/caliper brake) Part configuration: Relative size of hub to disk Relative size of rotor thickness to diameterConfiguration DesignPhaseDise o: Intro13 Example: Values for Parameters?Decide upon specific values for design diameter (outer) pad pressure on piston Parametric DesignPhaseDise o: Intro14 Example: Completing the details Decide upon the remaining manufacturing specifications machined rotor tolerances pad bonding resin assembly/testing procedureDetail DesignPhaseDise o: Intro15 Example: Final Form is the solution toa design problem Function----stop a spinning shaft Form Rotor: 10 inch diameter, steel, 3/8-inch thick, cooling passages Forged steel caliper/housing Brake pads, 2 opposing, 4 sq.
