Phase2: Conceptual Design

List of identified functions

1.Remove the plants floating on the water.

2.Sense the obstracle and take the turn.

3.Alert the user when there is problem in it’s operation.

4.Dispose the wastes that are collected.

2.1 Use case diagrams

2.1.1 List the tasks associated with each of the functions as indicated in the use case diagrams

## Function 1
1.Input data
2.Collects data given by user
3.Collects the wastage

## Function 2
1.Sense the obstacles
2.Alert the user
3.Take turn

## Function 3
1.Collects the wastages
2.Dispose the wastages

2.2 List the inputs, outputs of the system and represent black box model

## Inputs	Outputs
1.Power(Battery/Cell)	1.Sound,Mechanical energy
2.Material ( X )	2.-----------
3.Data(code/inbuilt program)	3.Movement

2.3 Write the glass box representation of the system in terms of functional blocks

Function	Mean1	Mean2	Mean3
1.Collect	Belt	Arm	Net
2.Sense	IR sensor	Ultrasonic	X-Ray
3.Alert	LED	Sound	Messege
4.Dispose	Mannual	Belt	Collecting chamber

Task 2.5 Ideate the solutions for the defined problem definition

Design Idea NO	Objective	Score given	Justifications
1	Safety	3	The machine safe for aquatic animals because it flots on the water
1	Easy to use	8	The machine can be operated by a single person
1	Collects different types of waste	5	The machine collects different types of wastes like plastics,organic materials
1	Use of standard parts	2	The machine has more standard parts for the safety of machine
1	Cost	-1	The machine is least cost as compaired to other machines
2	Safety	Datum	The machine is not cause harm to aquatic animals
2	Easy to use	Datum	The machine can be operated by minimum number of workers then compaired to other machine
2	Collects different types of wastes	Datum	The machine collects minimum wastes in the lake
2	Use of standred parts	Datum	The machine is made of some standred parts
2	Cost	Datum	The machine is an average cost as compaired to other machine
3	Safety	-3	The machine collects fish present in the lake while collecting the wastes
3	Easy to use	-4	The machine required more number of workers to operate
3	Collects different types of wastes	0	The machine collects some differents types of wastes like plastics,organic material
3	Use of standred parts	0	The machine has some standred parts with it
3	Cost	-1	The machine has more cost then that of other machines
4	Safety	3	The machine alerts the user by giving signals when any aquatic animal is entering into the collector
4	Easy to use	-8	The machine required more number of workers as compaired to other machines
4	Collects different types of wastes	-5	The machine collects only some different types of wastes
4	Use of standred parts	4	The machine has more standred parts then that of other machines
4	Cost	-2	The machine has more cost because it has more standred parts
