JUSTIFICATION OF PUGH CHART
| DESIGN IDEA NO. | OBJECTIVE | SCORE GIVEN | JUSTIFICATION |
|---|---|---|---|
| 1 | SAFETY | 6 | DISPENSING AND PACKING ARE EASY AND SAFER |
| AFFORDABILITY | 16 | MAKES USE OF SIMPLE MECHANISMS FOR DISPENSING AND PACKING | |
| PORTABILITY | 5 | IT IS LIGHT WEIGHTED | |
| AUTOMATIC | 0 | QUANTITY NOT DETERMINED | |
| 2 | SAFETY | 0 | NO MANUAL WORK DONE |
| AFFORDABILITY | -8 | TOO MANY COMPONENTS TO BE USED WHICH INCREASES COST | |
| PORTABILITY | -5 | TOO MANY COMPONENTS SO MACHINES BECOMES COMPARITIVELY HEAVIER | |
| AUTOMATIC | 14 | QUANTITY IS DETERMINED | |
| 3 | SAFETY | DATUM | NO MANUAL WORK DONE |
| AFFORDABILITY | DATUM | THE MACHINE IS METALLIC,WITH USE OF STANDARD PARTS LIKE STEPPER,SERVO MOTORS,SLIDERS | |
| PORTABILITY | DATUM | MACHINE IS HEAVY | |
| AUTOMATIC | DATUM | IS AUTOMATIC AS DISPENSING IS DONE BY SLIDERS | |
| 4 | SAFETY | 6 | DISPENSING AND PACKING ARE EASY AND SAFER |
| AFFORDABILITY | 8 | MAKES USE OF SIMPLE MECHANISMS | |
| PORTABILITY | 5 | IT IS OF LIGHT WEIGHT | |
| AUTOMATIC | 0 | NEEDS REPEATED INPUT TO SPECIFY QUANTITY(DISPENSING TIME) |
