Week 11 Lecture: Pugh Matrix & Set-based design

In this week contact session exercise, we generate concepts for consistently reproducing & representing 3D movement in space that allows a musical composition to be accurately played on a Theremin. Then use Pugh Matrix to compare concepts.

In order to generate concepts, I did some research about Theremin. So the Theremin is an early electronic musical instrument controlled without physical contact by the thereminist (performer). The instrument's controlling section usually consists of two metal antennas that sense the relative position of the thereminist's hands and control oscillators for frequency with one hand, and amplitude (volume) with the other. The electric signals from the theremin are amplified and sent to a loudspeaker. [1]

Concepts

1.     A conducting device to display some instruction of conducting hand movement

2.     Light laser to display the musical scale, so user can play it like play musical instrument

3.     Using AR device to allow user see some visual musical scales, then user can

4.     temperature Sensor that can help user to know their current musical scale

Pugh Matrix

For the set-based design, we using Pugh Matrix to define feasible regions, explore trade-offs and communicate sets of possibilities. Then integrate all possible idea to minimum constraint. Finally establish feasibility again before commitment it. Overall, it’s requires trying lots of ideas and pick a favourite then using tools to select (Pugh Matrix), combine aspects in the end.It’s very useful when explore about your concepts when you improving or designing.
