Final

Problem:
We need to store a bike to living space from being taken up.
Brainstorming:
have two hooks on the ceiling and then hang the bike by its tires
have two hooks on the wall and then hang the bike by its tires (better for dorms with tall ceilings)
if you have a balcony, just get a bike lock and lock your bike outside
put your bike on the shelf that is usually present in the closet
require a foldable bike for all people on campus, and make the expense part of the dorm fee (bike when folded could be stored on the shelf in the closet)
Criteria
bike storage
easy to assemple
Constraint
no permanent damage

Locker Assignment

I was absent on Friday when we did this assignment in class becuase I had to take an AP exam. I got as much done as possible, but it is not completely finished!!
Design Phase
Identify the Problem--
  • Lockers are a mess, design something to help organize them. 
Investigate the CHS lockers--
  • Regular Locker Dimensions
    • Width-10 in.
    • Height-17 in.
    • depth-11 in.
  • Football Locker Dimensions
    • Width- 14 in.
    • Height- 45.5 in.
    • Depth- 17 in.
Brainstorm Solutions--
  • Regular Locker:
    • 1st:
      • Have two shelves on the right side of the locker
      • Have a hook on the inside on the left side for backpack
    • 2nd:
      • Have one shelf on the top and one shelf on the bottom
    • 3rd:
      • Have a drawer on the bottom for pencils and paper
      • Have a shelf on the right side
      • Have hooks on the left side for hanging
  • Football Locker
    • 1st:
      • Have two shelves on the top on the locker for shoes, and padding
      • Have a bar below those two shelves for jersey's
    • 2nd:
      • Have one shelf on the top and then another shelf on the bottom
      • Have a bar below the top shelf
Sketch Three Possible Solutions (include labels and important dimensions)
 
Identify Criteria and Constraints
Criteria:
1. Design a locker on the CAD software
Constraints:
1. Design must fit within your school locker.
2. Easy to install.
3. Must hold 20 lbs of books and binders.
4. No flammable materials.
Select an Approach (justify selection with specifics)--
  • Football locker
    • One shelf on top for pads or helmet
    • One shelf on bottom for shoes
    • A bar below the top shelf for jersey, and jacket
Prototype Phase
Craft your design in CAD:
-Use an assembly of parts.
---Create an Isometric view of your assembly.
---Create a multiview drawing.
-----Label your multiview drawing with dimensions.
Each student will do their own CAD work (You may collaborate in and outside of your team but the actual work must be your own).

IDEO Shopping Cart

1. “From the buildings in which we live and work, to the cars we drive, or the knives and forks with which we eat, everything we use was designed to create some sort of marriage between _________________ and _________________.” Form and Function


2. The folks at IDEO state that they are not experts in any given area. But, they do claim to be experts on the ____________________, which they apply to the innovation of consumer products. process that they design stuff like the toothbrush...

3. After the team of designers is brought together, told the problem, and informed they have five days to “pull it off,” what phase of the design process do they immediately engage in? brainstorming designs

4. Give two examples of what the team members did during this phase.

a. drew sketches of the ideas they had
b. went to places where the people actually design and make shopping carts, and asked what they think


5. List five rules-of-thumb that IDEO employees follow when they share ideas during the brainstorming phase:

a. one conversation at a time
b. stay focused
c. encourage wild ideas
d. defer judgement

e. build on the ideas of others

6. Why should wild (and sometimes crazy) ideas be entertained during the brainstorming phase?
in order to stay focused


7. After the brainstorming phase was over, the team narrowed down the hundreds of ideas by _____________ for those ideas that were not only “cool” but also _________________ in a short period of time. What phase of the design process is this called?

looking, could be designed
Research and Generate Ideas


8. IDEO believes that the ideas and efforts of a ______________ will always be more successful than the planning of a lone genius.
trial and error



9. Once the ideas were narrowed down and divided into categories, the group was split into four smaller teams. What phase(s) of the design process was each of these groups responsible for?
Select an Approach
Almost like they went through 6-12 of the design process and then got into a bigger group and went straight to 6 again.



10. The leaders at IDEO believe that ________________ behavior and a ______________ environment are two important reasons why their employees are able to think quickly and creatively to produce innovative results.
working together, cahotic


11. Sometimes, people come up with great solutions that work by trying their ideas first, and asking for _________________ later.
forgiveness


12. Design is often a process of going too far and having to take a few steps back. What phase of the design process would the critique of the four mock-ups come under?
Explore Possibilities




13. Upon critique of the four teams’ models, it was obvious that none of the teams had developed an optimum solution. However, the people at IDEO believe that it is important to _____________ often in order to _____________ sooner.
fail, succeed


14. What percentage of the entire week’s time did it take to fabricate the final prototype?
it took 1 day aka a lot of hours to finish it




15. Instead of showering his design team with a tremendous amount of praise, what did the boss require his employees to do with their new design?
go to the local supermarket, and get other people's opinions




16. Of all the things that we are surrounded by every day, what has not been placed through the design process?
Everything in nature, but other than that everything has been put through the design process

Conclusion

1. What did you find to be the most impressive part of the team’s effort?
  • I thought it was impressive that the team worked so well together. Even if the team members did have a problem with another person it didn't show.
  • I also thought it was impressive that not one person did the whole project. Each person helped either by taking notes, drawing the design, or going to the supermarket. It really stands out when the whole team works together and not by themselves, much more efficient!!!
2. What advantages are there to having a design team with members that have non-engineering backgrounds?

3. There was a point in the process where a self-appointed group of adults stepped up, stopped the ideas, and redirected the group to break up into teams. Why was this done?



4. At the end of the video, Dave Kelly states, “Look around. The only things that are not designed are the things we find in nature.” Can you think of anything that would contradict this statement?
beaver damns- beavers have to design something in order to stop water and something to help them live in.

Glider in class test (4pts)

CAD MODEL

MULTIVIEW CAD MODEL

There was some confusion about this post. Emmet, Trent and I all had the same model. Honestly we all worked on it together, and I did the multiview drawing completely while Emmet watched how I did it. But, I know we were not supposed to work together on the glider. My computer freaked out after I had assembled the glider, and all the parts got saved, but the glider did not. I was in a time crunch and therefore used the glider that I helped work on with Trent and Emmet. If we would have had time in class on Thursday I probably could have finished, but I know the grades were supposed to be in so I put the same glider on my blog. I am sorry for having the same one, but I didn't want to have nothing on my blog.

Glider Challenge


The Grom Chillib Flyer
Design Phase: 
  1. Challenge: to design a glider that will fly the farthest, and a glider that will hang the longest in the air.
  2. Brainstorming rules: to discuss with all your group members to come up with the best designs that meet the criteria and the contraints.
      1. 1st rule: don't just use your own ideas, let others contribute and make a group effort to decide which one is the best.
      2. 2nd rule: draw the designs as you go so you don't forget!
    1. Ideas:
      1. have two wings, and one main part with paperclips in the front for weight
      2. have 4 wings, and one main part with paperclips on the front, and a bolt on the bottom for extra weight in the front.
      3. shape the wood in the front so it isn't squar, and then have two rectangular wings to provide the plane with more wing surface area.
    2. Sketches


  

  1. Criteria: make a glider with the given materials (tissue paper/computer paper, balsa wood, glue), tape, although many people added other materials
  2. Constraints: only allowed to use tissue paper or computer paper, certain amount of balsa wood, glue, and tape to construct a glider that beats everyone elses designs.
  3. Design:
CAD Model of The Grom Chillib Flyer
Test Phase

4 Quadrant Feedback Notes
Goals:
  1. Have glider stay in the air the longest
  2. Have glider fly the longest distance
In the first round we won both the challenges, but in the second round Jordan and his group won the longest distance challege.
We could have our wings more flexible, so they move up and down (fluttering) in order to keep the air under the wings at all times!!

Looking Over the Challenge
  1. Our glider won both the longest distance, and the longest time in the air in the first round.
    1. We were pretty happy, but then in the second round Jordan and his group came out with a great glider that soared and flew pretty far! Impressive for sure!!
  2. Looking back at Jordan's glider, we would have made our wings able to move and flutter like theirs in order to keep the plane flying straight for a while!
    1. The wings fluttering helps keep the air underneath the glider longer!!

    Reverse Engineering: Functional Analysis

    Standard Tape Measure


    1. What is the purpose or primary function of the object?


    Function...
    • To measure items that have unknown dimentsions
    • To measure the distance between items
    • Make measuring a one person job
      • metal hook allows the tape to be held onto the item and pulled out to measure the distance, or length of the item, etc
    • Makes measuring easier!!
    2. Make an educated guess as to how this product operates. Use simple machines’ terminology to explain the object’s sequential operation.


    How it works...
    • use a metal spring that is attached to the end of the measuring tape (inside the case)
    • other end of the measuring tape has a flat metal hook
      • hook on to one end of what you are measuring 
      • turns measuring something to a one-person job
    • when the tape is pulled the spring starts to unwind
    • it keeps energy in the metal spring
      • used to wind the tape up again
    • the hold switch holds the tape at a certain point
      • does this to stop the spring from unwinding
    • when hold switch is released the spring unwinds and pulls the tape back in the case  
    3. Identify the system inputs, intended product function, and outputs. Use powerpoint to create a "black box" graphic like the toothbrush example discussed in class.  
    4. What mechanical components are visible?
    Visible Components...
    • The hold switch is the only visible component
      • this helps to hold the spring inside so the tape measure doesn't randomly go back in the case
      • if you release the button the tape goes back in
        • Be careful it hurts!!!
    • The flat metal piece on the end of the tape to make measuring a one person job is also visible
      • helps to hold on to objects to measure in between distances
    5. What is it about this device’s function that you cannot identify, because the mechanical components are hidden from plain view?
    What's Missing...
    • The spring on the inside is not visible
      • supports the whole idea of how the tape measure stays out, and  how it goes back in with help from the hold switch and release switch on the top of the case
    • The coiling of the tape is also not seen
      • can't see how the tape wraps up within the case itself
