Lecture 12 introdution to Engineering design process – Part 2: Concepts, decisions and final design. The following will be discussed in this chapter: Learn remaining 5 phases in the engineering design process, coursework DE2 – Satellite hinge. | Design web Design web Objectives for today ME 1110 – Engineering Practice 1 Engineering Drawing and Design - Lecture 12 Learn remaining 5 phases in the Engineering Design Process Engineering Design Process – Part 2 Concepts, Decisions and Final design Coursework DE2 – Satellite hinge Prof Ahmed Kovacevic School of Engineering and Mathematical Sciences Room CG25, Phone: 8780, E-Mail: 1 Ahmed Kovacevic, City University London 2 Ahmed Kovacevic, City University London Design web Design web Engineering Design Process How to obtain an optimal solution Overall problem Overall solution Need and objectives Objectives tree Specification and communication Establish functions Functional model Analysis and decision Decision matrix Constraints and Criteria Specification Sub-problems 3 Ahmed Kovacevic, City University London 4 Solutions for individual functions Morph. chart Sketch for a concept variant Alternative sol. 2 Sub-solutions Ahmed Kovacevic, City University London Design web Design web 6. Alternative Solutions Derive alternative solutions for a problem In order to solve the problem group has to propose a list of possible solutions. More innovative solution – better product. The nature of Invention “Me an inventor ??!” ⇒ “Why not?” Are you afraid of that?? Building the List of possible solutions: a) Chekoff list » – – – – 5 or b)Brainstorming Checkoff list – designed to direct thinking It suggests possible ways how to change and use existing solution Make a list of the features for the first solution: shape, size, material, manufacturing method, colour, arrangement, Try to conceive how the current solution changes if you change features according to the words in your list. Ask yourself: Why is the solution like it is? Will change be better or worse? What was the reason for the original solution to be made that way? Use check list words: “MODIFY” and “REARANGE” to guide
