ENGR 101: Engineering Problem Solving I
Project 2: Medical Supply Drop Container
Introduction:
With the recent exposure of the world inhabitants to the Coronavirus-19. Development of a rapid deployment system for medical supplies without exposure of the delivery personnel is a desirable product. Your teams proposed system should be sized such that it can fit into an 8 ft (2.43m) cube and deployable from a standard air-drop cargo plane, the Lockheed L-100, via a paradrop.
Your job is to create and analyze the best design for the medical supply drop container. The design team is to evaluate the needs as well as create a storage and delivery container for the desired equipment and supplies to prevent the spread of any future disease and treat those infected. At the end of the project, each team will provide a single technical report and poster to document their design and include an analysis of how many people the system will treat and for how long it would provide a quarantine.
Remember, this medical supply drop container design will be used to safely deliver medical supplies into exposed territory from a plane, without landing. To help in the development process, your team should test 4 independent drop configurations and focus on things such as drop height, drop orientation (pull out or parachute), location of center of gravity, etc.
Rules:
• The first iteration drop container must not be more than 6.0 inches in height, width or depth.
• You cannot use edible materials.
• You may use any materials you wish but spend no more than $20 per iteration total. Power and hand tools are available in the FEP Lab (176 ESB) but are not required for completion of the project.
• You cannot buy a kit, you must design from scratch.
• Containers should be at least water resistant. The idea is that the integrity of the container would not be influenced by weather elements such as amount of wind, rain or snow.
• The container should be easily opened and closed. For example, you cannot tape the container shut before each of your tests, but you can use something reusable, like Velcro™.
• The drop container should wander no more than a 1 foot radius from the pre-determined initial drop location. Your goal is to get it to hit the ground as close to your initial drop location as possible. It can land then bounce outside of the 1 foot radius.
What you need to test and record:
• Please make sure you record the following things and use the data to compare it with your teammates to come up with a single final design. Please put the data in excel and make sure you include a table in your poster and technical report. You must have multiple trials (at least 5 trials per design). Again, put all this information into an organized table.
• Take at least 6 pictures of the drop container, showing all parts of it (inside and out). Include pictures with a ruler or tape measurer to show the structure’s dimensions, and pictures showing how the structure opens and closes.
• Record the exact height of drop and the device landing onto a concrete floor or other hard surface. Carpet, rubber, a rug, grass etc. are not acceptable landing surfaces. Include a picture of the full testing area, including drop and land site.
• Record the time from release to when it hits the ground for each trial. Calculate the average time it took for the drop container to hit the ground
• Record the number of inches from the initial drop location for each trial. For example, if you drop it, and it lands EXACTLY below it on the ground, your number of inches is 0. Calculate the average distance the container moves from the initial drop location.
• Record whether the container stayed intact or it was opened or damaged/destroyed in the process of testing for each trial.
• Record the size of the supply container (exact length, width and height to 1 decimal place). It’s not enough to just include pictures, you must explicitly state the dimensions.
• Analysis portion – this is the most important part! Calculate and show all data, as well as create graphs in excel to show…
o Velocity versus time (show/calculate time in increments of 0.01), until it hits the ground.
o Acceleration versus time (show/calculate time in increments of 0.01), until it hits the ground.
o Position versus time (show/calculate time in increments of 0.01), until it hits the ground.
o Also, create a graph that then shows ALL THREE (velocity, acceleration and position) in a single graph, each as separately colored and textured lines. Add a legend.
• Using the graphs you have created, use a section of the discussion portion of the report to explain what your calculations mean compared to the actually data you collected through experimentation. Some of the things you would want to explain in future work is how your design might change based on what you have calculated.
o For all of these, you must consider DRAG. The drag coefficient will be different based on your cross-sectional area (whether you use a parachute or not and then what your container looks like). Include all equations in the technical report as well.
Please use some of the other resources I have offered in the project 2 folder to help you in your calculations!
• TAKE LOTS OF PICTURES!
• If you can, and if it’s safe, it would also be cool to see the full potential of your container. So again, if it’s safe, go ahead and test from the highest place you can.
Individual design and Background:
Each student is required to design, build and test a medical drop container. Everything you need to test and record is listed in the above section (“What you need to test and record”). If you do not submit an individual design by the deadline, you will be removed from your group and receive a zero for the project. In addition, each member of the team is to find at least 5 Quality sources (Journals, Textbooks, Scientific Articles, .GOV and .EDU websites) of information that are relevant to the project and help with the decisions made during the project.
Final design and testing:
The final design MUST be a combination of parts of multiple designs (from each of the group members). You should have a picture on the poster and in the technical report showing what parts of the final design came from which individual designs/ideas. Your final design results should also show everything listed in the above section, “What you need to test and record”. When the final design is due, you should also submit this picture showing what parts of the final design came from which individual design/ideas.
Deliverables:
• Team charter and Team Gantt chart (assignment grade): Due into eCampus Project 2 folder by 3/31 @ 5:00 PM.
• Individual Design and Background (20% of project grade): Submit at least 6 pictures of your individual designs and an excel file of your tested data into eCampus project 2 folder to ensure that everyone is on the right track and working towards the final design and technical report in a reasonable amount of time. The minimum five sources of the Background must be discussed in a single cohesive discussion of prior knowledge about the topic. If you do not submit an individual design on time, you will be removed from the project and you will receive a ZERO for the project. Due by 4/8 @ 5:00 PM.
• Final design and excel data analysis (15% of project grade): I need at least 6 pictures of your final designs and an excel file of your tested data into eCampus Project 2 folder to ensure that everyone is on the right track and working towards the poster and technical report in a reasonable amount of time. Also picture of how each individual design influenced the final design. Due by 4/15 @ 5:00 PM.
