Task 2.1: For the chosen need statement, write the problem definition

To design a machine which is stable, automated, user friendly, safe to use, cost efficient, light weight and of size 30*30 cm. The machine is compatible and also functions on alternative sources of power supply. The machine is made up of acrylic material. As the machine incorporates all the above mentioned features, the cost estimation of the machine is around 5000 rupees. The machine is able to make two different patterns in two color variants on cylindrical cardboard box. The machine is capable to design ten such cylindrical boxes and works for two hours per day.

Task 2.2: Write use case diagram to represent the above system.

Task 2.3: Functional Structure (Write detailed system sub functions for each use case)

Use case	Sub function list
1) Display to select pattern and color	a) Once the object is placed, the machine allows the user to select patterns .b)After the pattern is selected, machine allows the user to select color for the same.
2) Working of the machine(pattern making)	a)When our machine is using a marker to make design, the motor in the machine will be rotating with a RPM of b)When our machine is using a crayon to make design, the motor in the machine will be rotating with a RPM of
3)Managing the resources	a)The machine shall sense the presence of the object and then the process begins.b)Also, the machine shall indicate if the resource (ink/crayon) is running out of supply.
4)Completion of the process	a) Finally, when the process is completed, the machine shall notify the user about the completion of the process with an indication.

Task 2.4: List the inputs, outputs of the system and represent black box model

Inputs	Outputs
1. Placing the object	1. Sensing of the object by the machine
2. Selection of the pattern	2. Making of the designs on the object
3. Selection of the colour for the pattern	3. Machine will alert the user after completion of the process

Task 2.6: Complete the morphological chart by exploring the other alternative means of achieving the sub functions. (You are allowed to use internet to explore means)

Functions	Mean 1	Mean 2	Mean 3	Mean 4
Display to select pattern and colour	LED	LCD	Remote operated	-------
Working of the machine(pattern and colour)	Marker(motor with a RPM of )	Crayons(motor with a RPM of )	Paint	-------
Managing the resources	Sensor	Refill bottle	Change of crayon	-------
Completion of the process(Indication)	LED light	Buzzer(Beep sound)	Digital display	-------
