Design 1 is selected as a best idea
Justification chart
Design 1
| Objective | Score | Justification |
|---|---|---|
| Dispense the object | 20 | Dispensing of object is very easy |
| Agile | 9 | wheels movement is quicker than roller |
| Good battery life | 8 | Complexity of Mechanism is less and feasible due to which Battery lasts long |
| Stability | 14 | Very stable as compared to roller |
Design 2
| Objective | Score | Justification |
|---|---|---|
| Dispense the object | 10 | Dispensing of the object is easy |
| Agile | -18 | Belt drive mechanism is faster than rollers |
| Good battery life | -8 | Due to more mechanisms battery life doesn't lasts long |
| Stability | -14 | It's not stable as the contact surface is very less |
Design 3
| Objective | Score | Justification |
|---|---|---|
| Dispense the object | 10 | Dispensing is easy as compared to design 4 |
| Agile | -9 | It's not that fast due to it's circular structure which opposes the speed of the wheel |
| Good battery life | -8 | Due to many mechanisms battery life doesn't lasts long |
| Stability | -7 | It's not stable as compared to datum |
Design 4
Design 4 is considered as Datum.
