THE BEST SUITATED DESIGN WILL BE DESIGN-2 THAT IS ROTATING CYLINDER DESIGN

JUSTIFICATION

DESIGN 1 - CONVEYOR BELT

SL.NO	OBJECTIVES	SCORE GIVEN	JUSTIFICATION
1.	Ease of use	0	Both the design are easy to use since we have to just push the button to get syringes dispensed
2.	Maintenance	+8	The Conveyer belt design is easy to maintain because unlike rack and pinion it doesn't require any kind of lubricant to run smoothly
3.	Storing medicine	0	Both the designs have same type of storing we have to put bottles or syringes one above the other
4.	Portabitallatlity	0	Both design can be carried easily however rack and pinion maybe little heavy
5.	Cost	+4	Conveyer belt design will cost less because it's mechanism is simple and have simple components unlike rack and pinion whose components are complex
6.	Size	0	Both the designs have same size

DESIGN 2

SL.NO	OBJECTIVES	SCORE GIVEN	JUSTIFICATION
1.	Ease of use	0	Both the design are easy to use since we have to just push the button to get syringes dispensed
2.	Maintenance	+8	Unlike rack and pinion this design is easy to maintain and has long life
3.	Storing medicine	-7	In this design we have to put each one-one syringe or bottle in each compartment which is a tedious process
4.	Portability	+10	This design is light weight and easy to carry
5.	Cost	+4	In this design the components used are very less and simple though the inner cylinder is complex to make but it is cheap
6.	Size	+2	The design being cylindrical occupies less space compare to rack and pinion which is cuboidal

DESIGN 4-LINKAGE

SL.NO	OBJECTIVES	SCORE GIVEN	JUSTIFICATION
1.	Ease of use	0	Both the design are easy to use since we have to just push the button to get syringes dispensed
2.	Maintenance	+8	This design is easy to maintain as the linkage requires no maintenance
3.	Storing medicine	0	In this design the syringes and the bottles are stored in a box it is on same level of that of rack and pinion
4.	Portability	-5	Due to its large size it is little difficult to carry
5.	Cost	-4	This design has more no. components so the cost maybe little high
6.	Size	-2	The linkage mechanism takes more space compare to rack and pinion
