The best concept selected is Design 1

Justification

Design 1:

objective	given score	justification
user friendly	++	it requires less manual interruption
cost effective	+	the cost is not very much high
portable	++	it can be carried anywhere
fully automated	++	less manual operation as it is operated through bluetooth

Design 2:

objective	given score	justification
user friendly	0	datum
cost effective	0	datum
portable	0	datum
fully automated	0	datum

Design 3:

objective	given score	justification
user friendly	0	It requires more manual interruption as it has 2 arms .so it is difficult to synchronise
cost effective	-	it is costly because it requires more motors and links
portable	+	it can be carried everywhere but it is heavy due to 2 arms
fully automated	++	it is fully automated

Design 4:

objective	given score	justification
user friendly	0	comparably same as that of datum
cost effective	--	it is to costly because involvement of motors is more
portable	+	it is portable but little heavy due to 2 arms
fully automated	++	it is fully automated

Identified list of sub system.

1. Accepting the type of tune by user

2. Playing the tune/movement of arms

                                       ## Interaction details:

Material interactions:

solids, liquids and gases that flow from one

sub system to next.

Energy interactions:

energies that must be transmitted or shielded

between sub systems.

Data interactions:

signals that must be processed from one sub

system to the next.

Spatial interactions:

geometrical dimensions, tolerances and

constraints that must be maintained between the sub systems.

Subsystem 1

	subsystem 2
Material interaction	No
energy interaction	Yes
data interaction	Yes
spatial interaction	No

There is energy interaction between the processes of user entering tune and playing the tune. Here AC source is used as energy and Bluetooth signal is taken as data interaction.
