Project Management: Coordination Review

Cause for Corrective Action

Gate 1 and Gate 2 for group 12 were both balanced in terms of work load among each of the group members. However, for the first two gates our group found itself with only 2 or 3 people scrambling to finish the wiki page. To address this we called for a group meeting after class on 11/9/2011. In which we divided the project amongst ourselves like usual. However, this time we agreed that all group members were to complete their sections by Sunday. At 1pm on Sunday the 13th of November, a meeting was held in Capen Hall to address problems we were having with our individual sections. After completion they were sent to Mark Stiegler for grammatical revision and then forwarded to Emmanuel Cabrera for a 3 day assembly of our wiki page. We hoped that by spending more time organizing our wiki page, we would in turn receive a high mark than our two previous sections that scored low.

Component Complexity

The following component complexity scale is used as a basis for comparison in the analysis of the vacuum components.

Low- A component with a low complexity profile would be constructed using a simple manufacturing process. A low complexity component would also be comprised of a single material. The production of these components would require minor knowledge because these parts are easy to design and fabricate.
Medium- A component with a medium complexity profile would be constructed using two to three manufacturing processes. They may also consist of up to two different materials. The production of these components would require general knowledge of manufacturing processes, but these skills could be acquired through experience.
High- A component with a high complexity profile is constructed using multiple manufacturing processes. They may also consist of two or more different materials. The production of these components would require an in depth understanding of multiple manufacturing processes.

The following interaction complexity scale characterizes the relationships between components within the vacuum.

Low- Interacts with less than two components and has a simple function in that interaction
Medium- Has connections to several different parts, and connects several systems, but is not a center for the system.
High- Interaction with many components and systems; also is an integral part that performs several complex functions

Top cover
figure 1: GAP
The location, figure 1, there is a gap between the floor and the top cover so that when the user is vacuuming the spinner can pick up the debris. The problem is that not all the debris is picked up so the consumer is forced to vacuum the area again. If larger debris is not picked up they can danger younger children and anyone who may step on the debris. Middle of back area has plastic cover to prevent this problem but the areas to the left and right of the wheels are not covered. Attaching a thin splash guard like figure #2 can easily prevent the problem.
Adding the splash guard will make the consumer more satisfided because less debris will be left behind. Bissel will be less economical because the splash guard would be more expensive to add to the vacuum, but the consumer would be more satisfied by the product.

Filters, #6, 8, and 11 in figure 3
figure 3:washable permanent filter
There are three filters in the vacuum cleaner. The filters are required to be replaced with new ones when the filters get dirty. When the filters are dirty but not replaced, the performance is decreased because air circulation is not performing properly. The replacement filter kit, Bissell 2032117, is sold for $23.25 by Bissell at amazon.com. The price of vacuum cleaner is around 60.00 used. The replacement filter kit is expensive compared to the price of the vacuum. Group 12 suggests changing the existing filters to permanent washable filters. Knowing that there are already a few purchasable nonreplicable filters group 12 is suggesting including this type of filter with the purchase of the vacuum.
Economically, Bissel would be less economical but the consumer would be more satisfied. Honeywell air purifier with permanent filter, Honeywell HHT-011 and HFD-010 is sold for $50 and $70 each and one HEPA permanent filter, Honeywell HFR-11, is sold for $18.95 at amazon.com, even if the air purifier filter is half of the entire air purifier products, the permanent filter would not be much more expansive than Bissell disposable filter. Environmentally, there will be no more filter disposal for the vacuum cleaner unless entire vacuum cleaner is disposed. Therefore, the vacuum cleaner will be more environmentally friendly. This modification will increase performance as well.

Change 3 Power cord #20 in figure ??

Power cord in this vacuum cleaner does not have ground plug connecter. If a consumer was to get the vacuum wet, the current would be grounded through the cosumer, however, 3-plug connector is directly grounded so, when short circuit is occurred, current will not flow through consumers.
This modification is related with societal concern for consumers’ safety. The 3-plug connector will keep consumers from electric shock when short circuit is occurred. Bissell would be slightly less economical by adding more material such as ground wire and plug as it sacrifices price for safety.

Engineering Analysis

Problem Statement

Motor Efficiency is very important for all electrical and mechanical devices. So in this analysis we are going to calculate efficiency of the electric motor in the vacuum cleaner.

Assumptions

  • Electric motor’s average angular velocity 3500 base rpm
  • Voltage Difference= 110 V
  • 12 A current needs to run motor
  • Energy losses due to heat and sound not included
  • Friction and wind losses not included
  • Mass of the motor= 5kg
  • Radius of the motor wheel= 0.05m
  • Gravitational Acceleration =9.8m/s2

Diagram

:
figure 4
figure 5





Governing Equations

T= Fr

F=mg
P in = VI
Pout = Tω
Efficiency (η) = (Pin/Pout) ×100 %

Where,

Pin & Pout= Power (W), V= Voltage (V), I= Current (A), T=Torque (Nm), ω=Angular Velocity (rad/s), F=Force (N), r= Radius of the motor wheel (m), m= Mass of the motor (kg), g= Gravitational Acceleration (m/s2)

Calculation

Using the equations and assumptions above, data will be gathered empirically, and then processed mathematically to find the efficiency of the electric motor in the vacuum cleaner.
  • Pin= 110×12= 1320 W
  • F=5×9.8= 49 N
  • T=49×0.05= 2.45 Nm
  • 3500 rpm= 366.5 rad/s
  • Pout=2.45×366.5= 898 W
  • Efficiency= (898/1320) ×100= 68 %

Solution Check

After finding the efficiency of the electric motor in the vacuum cleaner, the solution should be checked. This can be done using the equations outlined above in the governing equation and calculation section. We have to check the units and we have to check whether answer is reasonable for a motor efficiency.

Discussion

According to our calculation and assumptions, answer that we got is reasonable and reliable one. In this calculation we didn’t consider the energy losses due to friction, sound and heat. So 68 % of efficiency for an average motor is reasonable answer with our assumptions.

Solid Modeled Assembly

For the solid modeling in this part of the project we used Pro-E since it is a more common used software in most engineering jobs. It also helped us get familiar with the program for future classes.
