Justification statements

Design 1:

Sl.no	Objectives	Score given	Justification
1.	Compact and light weight	-	It has a large size compared to datum
2.	Crushing the cup	+	Can crush the cups faster and more efficiently than datum
3.	Safety	+	No blades are used so it's safer than the datum
4.	Stability	+	Much stable than datum due to heavy weight
5.	Portability	-	Cannot be moved easily as it has heavy weight

Design 2:

Sl.no	Objectives	Score given	Justification
1.	Compact and light weight	+	It has light weight
2.	Crushing the cup	+	It tears apart the cups while it should just crush them
3.	Safety	-	The blades are used so it's a bit unsafe
4.	Stability	-	It's less stable due to light weight
5.	Portability	+	It has eased in portability

Design 3:

Sl.no	Objectives	Score given	Justification
1.	Compact and light weight	+	It's compact but has heavy weight
2.	Crushing the cup	-	It tears apart the cups while it should just crush them
3.	Safety	-	The blades are used so it's a bit unsafe
4.	Stability	+	It's comparatively less stable
5.	Portability	+	It cannot be easily ported

Design 4:

Sl.no	Objectives	Score given	Justification
1.	Compact and light weight	0	Datum
2.	Crushing the cup	0	Datum
3.	Safety	0	Datum
4.	Stability	0	Datum
5.	Portability	0	Datum
