  1. The Morphological Chart“For creating and visualizing a design space and identifying the design alternatives within that space”HOW DO I MAKE ONE!?

  2. Constructing a list of functions and attributes • Well it’s quite easy.. We first want to do the following: • 1) Construct a list of functions our coal shearer scrubbing device must perform and the attributes or features it must have. • 2) List all the different means of implementing each function or attribute identified

  3. Need an example?(Can skip if everyone understands) • For a beverage container problem consistent with the object Promote Sales: it might look like this:1) Contain beverage 2) Material for beverage container3) Provide access to juice4) Display product information5) Sequence manufacture of juice and container We then list all of the means by which each of these functions and attributes can be achieved and attach them to their corresponding entries: 1) Contain beverage Can, Bottle, Bag, Box2) Material for Beverage Aluminium, Plastic, Glass, Cardboard, ect..3) Provide access to juice Pull-tab, Insert straw, Twist top, Tear corner, Zipper, ect4) Display product information Shape of container, Labels, Colour of material 5) Manufacturing sequence of Concurrent, serialjuice and container

  4. Once we have the tabulated data we can make our Morph chart! • The Morph chart is set up like a matrix. • The required functions and features are listed in the matrix’s leftmost column, while each function and attribute the means are identified and listed in the cells in the corresponding row. • We assemble designs in the classic “Chinese menu” style, choosing one means from each of the rows A, B, C ... To combine into a design scheme. Next slide for visual example

  5. Pruning the design space! • Whilst creating this Morph chart provides a way to create a design space and identify alternatives, it also provides the opportunity to prune that design space by identifying and excluding incompatible alternatives! • To exclude such alternatives we can apply design constraints, physical principles and plain common sense. We should also remember that technologies and, consequently, available means do change over time. • EXAMPLE OF FEASIBLE AND INFEASIBLE MORPH CHARTS ON NEXT TWO SLIDES
