5.1 Justification for the scores

Design 2(Shreeharsha)	Objective	Score alloted	Justification
01	User-Friendly	+16	As the cups are placed on required position, the crushing of cup takes place and easy to use.
02	Weight	+6	As the weight of machine will be less as it does not contain heavy objects
03	Portability	+3	As the machine is small in size and it is portable.
04	Cost	+4	As the components in the machine are not expensive and affordable, hence it is cost-effective.
05	Automatic	-6	As we have to manually place the cups that are to be crushed

Design 3(Adwait)	Objective	Score alloted	Justification
01	User-Friendly	16	This process is easy to use just put the cups and let the machine run its conveyer belt which will finally crush it off
02	Weight	-6	As the machine has some heavy components.
03	Portability	-6	This has fragile and too many moving parts which contradict the fact of portability
04	Cost	-4	The machine components are not easily installable and have to be used with high powered motors to crush multiple cups if the cup contains any of the liquids, the motors must be hydroponically covered
05	Automatic	06	It is automatic when we place the cup on the conveyer the machine automatically starts its process

Design 4(Sagar)	Objective	Score alloted	Justification
01	User-Friendly	16	The process is very much simple and it is user-friendly.
02	Weight	-6	this machine is comparatively weight.
03	Portability	-3	Due to the absence of flat base it is difficult to transport.
04	Cost	4	The components in the machine are not expensive, hence it is cost-effective.
05	Automatic	-12	there is no sensor to sense the cup and we have to switch on and off the machine.

5.5 Interaction between Subsystems

Identified Subsystems

1)Cup Holding Unit

2)Crushing Unit

3)Disposal Unit

Interaction Details:

Sl No.	Interaction	Details
1	Spatial Interaction	The estimation of movement of material(cup),services,information between locations in sub sytems.
2	Data Interaction	Data interaction is present as the machine involves sensors to sense the cup.
3	Material Interaction	Since the paper cups are first moved from Subsystem 1 to Subsystem 2 for crushing and then moved to subsystem 3. Hence there is Material Interaction between the Subsystem
