A. PUGH CHART

Table 1- Assign weights to the objectives

Objectives	Weights
Hygiene	09
Portability	08
Ease of use	09
Aesthetic	07
Cost	08

Table 2 : Write Pugh chart for the 4 alternative designs

Design Objectives	Weights	Design 1	Design 2	Design 3	Design 4
Hygiene	09	datum	"+"	"++"	"0"
Portability	08	datum	"-"	"+"	"+"
Ease of use Hygiene	09	datum	"-"	"0"	"-"
Aesthetic	07	datum	"+"	"+"	"0"
cost	08	datum	"-"	"+"	"+"
Score(+)		"0"	"16"	"41"	"16"
Score (-)		"0"	"-25"	"0"	"-18"
Total		"0"	"-9"	"41"	"-2"

B. JUSTIFICATIONS

Task 3 : Justification for the scores given

DESIGN NO	Objective	Score Allocated	Justification for the Score
01	Hygiene	Datum	It is taken as reference
	Portability	Datum	It is taken as reference
	Easy of use	Datum	It is taken as reference
	Aesthetic	Datum	It is taken as reference
	Cost	Datum	It is taken as reference
02	Hygiene	"+"	it can be maintained cleanly
	Portability	"_"	it occupies more space
	Easy of Use	"_"	it is not made compact
	Aesthetic	"+"	it has good look compared to others
	Cost	"_"	its is not cost effective few extra materials are used
03	hygiene	"++"	it can be easily cleaned
	Easy of Use	"+"	it is made with parts and it is compact
	Portability	"0"	it is made vertically therefore it occupies less space
	Aesthetic	"+"	it looks very nice
	Cost	"+"	it is cost friendly due to easy available parts
04	Hygiene	"0"	it is not easily maintained as datum
	Portability	"+"	it is easily movable
	Easy of use	"-"	it is with several mechanism and it is not easy to syncharise
	Aesthetic	"0"	it looks are not that much good as the other design
	Cost	"+"	It is cost friendly in which less cost materials were used
