156B Week 1

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Analysis:

    • Our previous work was only observational and establishing a solid understanding of how all aspects of the CAEP Facility work together

    • This included making a chart of the time of each type of washed cart in its cleaning lifecycle:

• • Design: after meeting and shadowing all aspects of the CAEP Facility, we have come up with the following possibilities:

    • Circular racks:

• • Fabrication: the team is currently researching material options to withstand the intense pressures, temperatures, and physical abuse that these logistic carts will be experiencing (stainless steel, chrome steel, aluminum)

    • We are considering the types of skills and technologies necessary to manufacture the new logistics cart, which we are calling the Buffalo (current carts bare names such as Llama and Mule)

      • These include different types of welding type for welding steel and aluminum and which forms will allow for the most durable welds for the given material

    • We are also looking at types of hardware that will allow the carts to be easily maintained and serviced if necessary and or not having to be serviced at all.

      • Industrial hardware ratings for bolts, nuts and other subassemblies such as the wheels, and bearings

  • Tests:

    • We are working with Keith to schedule testing days throughout the quarter where we can wheel in our current prototype and conduct control as well as independent tests

    • Currently, it has been established that early morning is best as there are no carts needing to be cleaned at this time.

Accomplishments from Previous Week

• • Our accomplishments from the previous week (quarter) are in a presentation linked here: https://docs.google.com/presentation/d/1uzA8aCGMoi3us2uM_EktxU2Xu2IuxJbDUVRqGDaFN78/edit#slide=id.g49e6517562_3_20

  • We are now ready to begin our design and prototyping phase

    • Purchasing will not begin picking up

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Begin ordering material and creating the three prototypes to test in the wash tunnel

  • Begin establishing a test procedure and create a document such that whoever from the team is there conducting tests that the same and the quality of the measurements are constant across time.

  • Get detailed max/min measurements of important parts of the facility such as the length, width, and height of each of the two washing tunnels.

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments

• • Drawings of potential solutions and possible prototypes to create

  • Further iterations of our initial test to make the concept work

Instructor Comments from Last Meeting and Actions Taken to Address these Comments

• • N/A

Risks and Areas of Concern

• • We want to prototype three very different designs to see feasibility, we are concerned about the time this will take and the extra costs

Resources or Information Required but not Available

• • Types of material used on current logistic carts?

  • How does the plastic wrapping machine locate on the cart?

  • What is the optimum way to hold components to wash well and store easily

  • Who makes the custom tools that the Cleaning Facility has had made in the past?

Schedule

• • Meet with sponsor to touch base and discuss design ideas and future prototyping plans (01/11)

    • Complete budget form at sponsor meeting

    • Consult sponsor for information regarding material options, component arrangement for respective designs, and other logistics.

Budget (list amount spent and amount remaining)

• • $0 Spent on Parts

  • $2000 remaining

Progress on Report and Webpage

• • N/A
