| 02. | Dimensions 2ft2ft2ft |
| 03. | System should be able to grow atleast two crops |
| 04. | The budget of the system should not exceed Rs.6000 |
Problem definition version 1.2
Design a semi or fully automatic hydrophonic system,which is able to grow fodder without soil.It should be portable and should not be labour intensive.It should consume less space and can grow fodder in 6-8 days.The dimensions of the system 2ft*2ft*2ft.The budget of the system should not exceed rs .
3.5 Establish functions
STEP 1 Prepare a list of design functions table 5: identified functions
| SL.No | Functions |
|---|---|
| 1. | Minimizing the chances of fungus production |
| 2. | Pumping water |
| 3. | Dispensing seeds |
| 4. | Pumping water |
| 5. | Indication of overflowing |
| 6. | Indicating pH range |
| 7. | Measuring electrical conductivity |
| 8. | Alerting the user |
Problem definition version 1.3
Design a semi or fully automatic hydrophonic system,which is able to grow fodder without soil.It should be portable and should not be labour intensive.It should consume less space and can grow fodder in 6-8 days.The dimensions of the system 2ft*2ft*2ft.The budget of the system should not exceed Rs. .The system should consume less amount of water and it should also provide nutrients.Growing the fodder through the system is simple and cost effective.The system should automatically adjust water to target pH range by disprnsing acid/base solutions.
