Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Design and Test - Prototype out of wood has been done and tested with two different weights, one with just empty plastic box approximately ~ 5 lbs (2.26 kg) and the other was loaded box approximately ~ 10 lbs (4.5325 kg)
Fabrication - The purchased still on delay since William and sponsor figured out the "Handle-It" product can't be the solution due to the portability and the fact that the power supply is greater than the predetermined maximum of 12 Volts.
Purchase Order - Wood for prototype from Home Depot.
Team is trying to accomplish some CAD model before the next meeting
Accomplishments from Previous Week
William on Thursday - After contact the "Handle-It" and discussed the product with the sponsor, we found out that "Handle-It" can't be the solution due to it is powered by 115 V
William on Thursday - Did research a further solution for the project and found couple companies, which are "Air Technical Industries" and "Lift Products" Inc. , status: Awaiting for reply
William on Friday - Both companies website are already sent to the sponsor and still waiting for Harold to respond about it.
Josh and Romulus - Completed Select sections of the Report for Week 2 and 3.
Josh - Determined complete list of deliverables and requirements from sponsor.
Team - Completed the fabrication of the prototype.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
William - Try to get a quote of the price from both "Air Technical Industries" and"Lift Products" Inc.
William - Discuss more in depth about two different products with the sponsor and obtain an agreement before put in the purchase order.
Team - Construct a draft for the CAD on the future design for modification purpose.
Team - Determine the driver (Hydraulic/Pneumatic/Lead Screw), Material, tilting motion for product.
Romulus - Review/Revise Report.
Josh - Determine optimum length of outriggers.
Josh - Convert previous analysis from paper to word for placement in report.
Dev - Determine the maximum height that the cabinet can be and still meet the requirements of the sponsor.
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
In person during the meeting on Wednesday(4/10/2013) - Harold was commenting on how the power is generated to the "Handle-It" Inc. product and encouraged the team to keep in touch with the company.
Via email on Friday - Harold found out that the power is generated with 115 V and he sent some suggestions on putting parts together that essentially build the apparatus from scratch.
Sponsor stated that we should steer clear of products from Vestil, as their experience with them has shown that the savings is not worth the repeated failures of their equipment (4/10/2013, in person) - Vestil has been eliminated as a company to purchase from.
Sponsors stated that they would like to see more pictures, before, during, after of the product and once we begin the fabrication they want the meetings changed from their offices to our Lab (in person 4/10/2013) Action Taken: Noted.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
None: Last week was presentation (4/8/2013).
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Many of the other students brought up the idea to look into Pneumatics as a driver for the tipping motion (4/8/2013, After Presentation, in person) Action Taken: currently researching.
Won't the modification of an existing design reduce the maximum capacity (4/8/2013, After Presentation, in person) Action Taken: duly noted, analysis will have to be performed, including asking the company about failure areas in their product.
Risks and Areas of Concern
Time constraints - this problem comes out because the difficulty to communicate with the companies, also the shipping of the product can be delayed
CAD design - although the final design is already in my mind, the complexity of the design still considered difficult
"Air Technical Industries" - lack on specification even though on the description they put a note about an alternative to generate the tilter with battery, still concern that how much power that required. Is it 12 V or 24 V? - This is a concern because we are limited to 12 Volts.
"Lift Products" Inc. - still waiting for their answer on the manual tilter. Manual titler could be one of our solution since it is satisfied one of the demands from the sponsor. However, the product can only tilt up to 40 degrees. We must determine if this angle is sufficient for tipping of the
Resources or Information Required but not Available
Specification sheet in depth for both companies. Although they have a catalog, still require sometime to get that. (Refer to Time constraints concern)
Schedule
Finalize Design, consult with Sponsor/Instructor and begin the purchase of components.
Update Gantt chart.
Budget (list amount spent and amount remaining)
Spent $4.08, Remaining $8495.92
Progress on Report and Webpage
Webpage is being built up weekly and all sections of the report required for weeks 2 and 3 have been uploaded, revisions are in progress.
