Tutorial #5 Instructor: Dr. Raja Rizwan Hussain Course: GE 105 Introduction to Engineering Design Creativity- Generation of Design Concepts

#1 A public transport system must be designed. There are several alternatives: – Power: electric, gasoline, diesel, gas turbine. – Medium: underground, overhead. – Support: rail, tires. Use morphological analysis technique, organize and discuss the design alternatives.

#1 Alternative designs Power : Electric underground overhead rail subway tram monorail tires N/A electric bus N/A Power : Diesel underground overhead rail diesel train tires N/A diesel bus N/A Power : gas turbine underground overhead rail gas turbine train gas turbine monorail train tires N/A diesel bus N/A

#2 Develop several design concepts for a domestic door security device.

Conventional design concepts 7

#2 l Code Based Security – PIN Code door – Magnetic Card l Human Interface/interaction security – – l Finger Print recognizer Voice Recognizer Face Recognizer Retina recognizer IT Based security – SMS Alert to mobile phone – Email alert system – CCTV

Example for #3 Develop a morphological analysis for a mosquito killer device.

#3 Power : Electric, Hand Power, chemical reaction l Killing method : electric wire, chemical, biological l Chemical Form : Aerosol, Liquid, Solid Pad, Nonchemical l

#4 A need is perceived for a “device to remove dust from carpets at home”, generate several concepts and comment on them

#4 Concept and comment : l Vacuum: clean but noisy, expensive l Broom: less clean but silent and cheap l Sticky Roll : less clean but cheap, easy, silent

#5 Setup the attribute list (criteria for successful design) for design a Notebook (portable computer).
