| sr.no | Questions such as | This question helps the designer to |
|---|---|---|
| 1. | What are the tasks you require the machine to do ? | |
| 2. | What are the pollutants to be removed by the machine? | Establish client’s objectives |
| 3. | How should the machine be controlled? | |
| 4. | How much can it cost? | |
| 5. | How much space will the machine provide | Identify constraints |
| 6. | At what depth should the machine clean? | |
| 7. | What measurements in the lake you expect to be cleaned by the machine? | |
| 8. | Do you want the machine to collect the waste in separate collector? | Establish functions |
| 9. | Do you want the machine to also remove the garbage thrown on the banks of the river? |
Obtain the information through basic survey
| sr.no | Observation and from Lit.Survey | Requirements |
|---|---|---|
| 1. | Based on the weight of the robot so that people should easily use it | Robot weight should not exceed 5 kgs |
| 2. | Based on the cost of other machines in the market | The cost of the robot should be lies between Rs 3000 to 4000 |
| 3. | It should be environmental friendly and user friendly | It should not harm the aquatic animals |
| 4. | Time taken should be less than other projects | Maximum 3-4 weeks to complete this project |
| 5. | Working hours should be more than other machines in market | Minimum 6 hours at a time it should work |
| 6. | It should clean as much as more area at once | Cover at least 30 sq per hour |
1.1 Identify client’s objectives
Step 1: Prepare a list of design objectives
| Sl.No | Objectives |
|---|---|
| 01 | Machine should be environmental friendly |
| 02 | Machine should work more in less time |
| 03 | Machine should weight less and should be small in size. |
| 04 | Machine should have good sensing technology. |
| 05 | Machine should be portable |
| 06 | Machine should clean continuously for 6 hours. |
1.2 Prioritize the identified design objectives
Priority among various objectives is set through a technique called Pair-wise Comparison Chart (PCC)
| Objectives | Safety / stable | Environmental friendly | Cost effective | Durability | Total |
|---|---|---|---|---|---|
| Safety / stable | ***** | 0 | 0 | 1 | 1 |
| Environmental friendly | 1 | ***** | 1 | 1 | 3 |
| Cost effective | 1 | 0 | ***** | 1 | 2 |
| Durability | 0 | 0 | 0 | ***** | 0 |
Rank the objectives in order of decreasing value of importance and the list is
- Safety
- Environmental friendly
- Cost less
- Durability
Based on the information gathered through interaction with client, initial survey and completing phase 1.1 the problem definition is formulated as follows
Problem definition version1.1
| Design a device that should be able to collect floating waste and clean the lake without harming other aquatic animals. The device should be able to continuously work for longer hours. |
|---|
1.3 Identify constraints
-
Building the device should not cost more than Rs4000
-
It's weight should not exceed more than 5kg
Problem definition version1.2
| The machine will automatically sails and cleans ,and collects all garbage and stores in collector. |
|---|
1.3 Establish functions
-
It should collect the waste.
-
It should move the collected waste into storage bin.
1.3 Problem definition
