JUSTIFICATION FOR THE SCORE GIVEN

Design No.	Objective	Score Allocated	Justification for the Score
1	Size	7	It would be small in size as its construction is less
	digital	0	It is also a digital clock
	user-friendly	-9	As the clock moves, there is a possibility that it falls down and break
	automatic	0	It will start functioning at the set time
2	Size	7	Less complex hence small in size
	digital	0	It is also a digital clock
	user-friendly	-18	Requires more time to solve a puzzle
	automatic	-7	Requires time to get off
3	Size	0	As it is a digital clock, it would be accurate
	digital	0	It would be small in size as its construction is less
	user-friendly	0	It is also a digital clock
	automatic	0	Launches ball as soon as the alarm starts beeping
4	Size	-7	Little complex in construction and larger in size
	digital	0	It would display time and number of balls in the sensing region
	user-friendly	9	It is effective in waking up the person
	automatic	14	Launches ball as soon as the alarm starts beeping and gets off as it senses the ball
