Justifications:

Design Idea no	Objective	Score given	Justification
1	precise stacking	+8	it places the soap box systematically
	cost	+10	high amount tools are not required
	quick stacking	0	it takes much time to lift and stack the box
	Ease of use	+6	it can easily pick and place the box
3	precise stacking	+8	AS the vehicle moves in one direction so there is less error of miss alligning the box
	ease of use	+6	as the vehcal is automatic and less intervention of human is require which makes it easy to use
	quick stacking	+14	as the vehicle only moves in one direction and it does not picks the box so the time is saved between picking and changing direction of the vehicle
	Cost	-5	as the number of components are more as well as the structure is larger so the cost is high
4	ease of use	+6	as it collects all the soap boxes by itself the human work involved is very less
	cost	-5	as the more number of materials is used like conveyer belt the cost is high
	quick stacking	+7	after collecting the soap box it stores the boxes in the container inside it instead of placing it in another place so it saves time
	precise stacking	0	while collecting the soap box there is a chance of slippage so this machine cannot be able to stack precisely
