Product and Process Design and Development
Vacuum Cleaner
Step 1: Constraints and Assumptions
➢ The vacuum system runs on an internal motor
➢ The vacuum is dynamic and moveable
➢ The vacuum removes dirt using suction
➢ The vacuum stores the collected particles
➢ The vacuums storage unit must be able to be emptied
Step 2: Function Tree
[See secondary documents]
Step 3: Subtract and Operate Approach
|PART REMOVED |EFFECT IN FUNCTIONING |
|Top Assembly: | |
|Wire Assembly | |
|Wire wrapping mechanism |Without the wire wrapping mechanism the wire will keep obstructing the|
| |path of the user while cleaning. It will also become inconvenient for |
| |storage purposes. |
| |Thus the wire wrapping assembly will not stop the working of the |
| |vacuum cleaner but will just ensure safety and easy storage. |
|Wire |Without the wire there will be no current input to the motor and hence|
| |the motor will not work. Thus the vacuum cleaner cannot work without |
| |the wire....
