10.1 Design Failure and Model Effect Analysis:
| Process Step/Input | Potential Failure Mode | Potential Failure Effects | S | Potential Causes | O | Current Control | D | RPN |
|---|---|---|---|---|---|---|---|---|
| Conveyer Belt | Conveyer Belt will not rotate | Tiles on the conveyer belt will not fall down | 8 | Conveyer Belt drive is moving towards the side | 10 | Manuel displacement of Conveyer Belt back to where it belongs | 1 | 80 |
| Rack and Pinion | Failure do to increase in load | Tiles will not be pushed onto the Conveyer Belt | 8 | Size of Rack and Pinion is too small | 10 | Only one tile is being placed at a time | 1 | 80 |
| Wiring | Motors will not be actuated | Tiles will not be laid | 6 | Faulty wiring | 5 | Check wiring before turning on adapters | 7 | 210 |
10.2 Process Failure and Model Effect Analysis:
| Process Step/Input | Potential Failure Mode | Potential Failure Effects | S | Potential Causes | O | Current Control | D | RPN |
|---|---|---|---|---|---|---|---|---|
| Aligning of Rack and Pinion | Pinion will not move the Rack | Tiles will not be pushed on to the conveyer Belt efficiently | 6 | Improper alignment of Rack and Pinion | 7 | Current Control | 3 | 126 |
| Wrapping Conveyer Belt | Belt will not rotate efficiently | Tiles placed on belt will not move to required speed | 6 | Belt has not been tightly Wrapped | 7 | Visual inspection if there is any slack | 4 | 168 |
