4.3 JUSTIFICATION

Design No.	Objective	Score Allocated	Justification for the Score
1.Circular Ring Clock	Portability	Datum	---
	Ease of Use	Datum	---
	Automatic	Datum	---
	Low Maintenance	Datum	---
	Cost	Datum	---
2.Hoberman Ring Clock	Portability	18	The arrangement of parts in the model are compact, so it can be portable easily.
	Ease of Use	20	Easy to operate the controls.
	Automatic	8	The Model is Completely Automatic.
	Low Maintenance	7	Its easy to maintain
	Cost	-9	This may cost more
3.Square kinetic Movement Clock	Portability	-18	This specific design is a bit difficult to handle. So it needs to be placed as such to avoid any damage
	Ease of Use	-10	As compared to the Reference,this invloves a bit of complex mechanism to operate.
	Automatic	0	The model needs continous observation for selection of patterns and directions which requires manual interpretation
	Low Maintenance	-7	The Model requires a good maintainence as the needles are very sensitive.
	Cost	9	cost effective
4. Perpetual Motion Clock	Portability	-18	This specific design is a bit difficult to handle. So it needs to be placed as such to avoid any damage
	Ease of Use	-10	As compared to the Reference,this invloves a bit of complex mechanism to operate.
	Automatic	0	The model needs continous observation for selection of patterns and directions which requires manual interpretation
	Low Maintenance	-7	The Model requires a good maintainence as the needles are very sensitive.
	Cost	0	Cost effective
