5.1 JUSTIFICATION FOR SCORES ASSIGNED

Design No.	Objective	Score Allocated	Justification for the Score
1	safety	7	it's little risky as the roller crushes the can
--	Ease of Use	8	does not require man power
--	portability	5	it's not portable as it consists of long bars and piston
--	automatic	9	it's automatic as it has a sensor
--	Cost	9	high cost as it consists standard parts
2	safety	--	it's safe as the process of crushing takes place internally
--	Ease of Use	8	The process does not include lot of arm strength
--	portability	5	it's not portable as it consists of piston and motor
--	automatic	9	it's automatic as it has a sensor
--	Cost	9	high cost as it consists standard parts
3	safety	9	it's safe as the process of crushing takes place internally
--	Ease of Use	8	The process does not include lot of arm strength
--	portability	5	the machine is not compact
--	automatic	9	it's automatic as it has a sensor
--	Cost	9	high cost as it consists standard parts
4	safety	8	The process does not include lot of arm strength
--	Ease of Use	8	it's convinient to use
--	portability	5	it consists of motor and rollers
--	automatic	9	it's automatic as it has a sensor
--	Cost	9	high cost as it consists standard parts
5	safety	8	it's not safe as the process takes place externally
--	Ease of Use	8	the process is simple
--	portability	5	it's not portable as it consists of complex mechanisms
--	automatic	9	it's automatic as it has a sensor
--	Cost	9	high cost as it consists standard parts
