Iterative design development

This design exercise will develop your iterative designing capability.

Iterative design development is the process of analysing, evaluating and modifying designs, then repeating the process until a suitable design is found.

You will start with a hazy idea for a sign and sign holder and develop the idea into a clear and detailed design.

An image showing the Flash animation logo SWF Flash logo is a link to a Flash animation.

Flash animations are embedded into the pages of all my D&T Modules but there are pictorial links to the animations on this web site so that devices that cannot play Flash animations will at least show a jpeg screenshot of the animation.

If your PC or personal digital assistant (PDA) can play Flash animations you may click on an image showing the Flash animation logo SWF Flash logo to view the animation in a new window.

Design Development

An idea for a sign and sign holder is illustrated above.

The design is still only a "hazy impression" of what could be because there are lots of things about the design that are still uncertain, e.g.

These are some of the questions that need to be answered. There will be others.

What you have to do

Draw the design of the sign and sign holder shown in the animation above.

Develop the design so that all problems are solved and you have a design that could be made. Use notes and sketches to record your ideas as they develop. Your modified design must have sufficient detail and information on it for someone to be able to make the sign and sign holder without needing extra information from you.

Your final design must be drawn to scale using orthographic projection.
