Activity 7.6 Apollo 13 Design Brief

Client: Apollo  13 Astronauts
Designer: NASA Engineers

Problem Statement: Apollo's external oxygen tank has overheated and exploded, pretty much crippling the electrical system. Two thirds of the fuel cells have lost. The astronauts are demanding a way for Apollo 13 to safely return home.

Design Statement:

Design an air cleaning mechanism that would keep the air in the lunar module from developing dangerous levels of carbon dioxide being exhaled by the astronauts themselves. Instruct the astronauts on the design so they can save themselves.

Design Criteria:
1. Can be assembled quickly
2. Easy to assemble
3. Requires everyday supplies that can be used for the assembly
4. Saves the astronauts
5. Does not diminish the supply of oxygen
6. Does not affect the fuel supply
7. Does not require to many supplies to the point where it may affect supplies needed for other tasks.

Design Constraints:
1. Must be built in less than an hour
2. Must use 2 LCG bags, cardboard from reference manuals, socks, canister, red suit hoses, and duct tape.
3. bags can't be ripped
4. Tape needs to seal the canister to prevent extra air flow
5. partial pressure of CO2 has to be relatively low
6. Does not emit toxic chemicals
canister, red suit hoses, bungee cord, and most importantl! duct tape
Conclusion

1.    How does the short deadline to solve the problem affect the design solution?
 The time constraint may affect the design solution to be simpler and not as effective as if a team had more time to thoroughly confirm the design solution works. The time constraint also challenges engineers to come with the best idea within that time constraint.



2.    Explain the importance of a design brief for this problem.
 The design brief ensures that everyone knows what the problem is, what is required to solve the problem, and what is to be done or not done. It also ensures that the engineers are tackling the right problem.

Day 15  Intro to Engineering Allen Sam 7-3-18 Activities 7.3 and 7.4 7.3 Tolerances 1.       Study the drawings below to identify specified tolerances. a.       Highlight each dimension that has a tolerance associated with it using something like a highlight marker. b.       Identify the type of tolerance in each highlighted example by labeling each tolerance dimension with one of the following: limit dimensions, unilateral tolerance, or bilateral tolerance. c.       Label each identified tolerance with a separate letter, A through Z. d.       Beginning on a new page in your engineering notebook for each part, record the letter of each tolerance identified on that part drawing, the type of tolerance, a short written phase that describes the dimensional variation allowed for that dimension, the tolerance (a number representing the total allowed dimensional variation), and an explanation as to why that particular dimension requires a tolerance.

Day 12  Intro to Engineering Allen Sam 6-27-18 Activities 5.5a and 5.5b 5.5a   Conclusion:  1.        What 3D CAD functions could be used to create a wire coat hanger? I would use the sweep, loft, and revolve functions of CAD to create the coat hanger from the front view and a side view. Activity 5.5b \ Conclusion:  1.    What CAD feature would be used to most efficiently model a baseball bat (Extrude, Loft, Revolve, Sweep)? Explain your answer. I would use the revolve tool to create the baseball bat because the baseball bat is cylindrical     2.    How does a 3D CAD solid model program display the progression of work involved in creating a model? You can see progression of the work of a project by showing the constraints and CAD features that were used. 3.    If a mistake is made, how does the user make a correction without using the undo function? The user would either use the delet
