Abstract[edit | edit source]

The purpose of this project is to create a protective barrier for the indoor lab. In hopes the protective barrier would put the students and teachers of six rivers charter school one step closer to going back to school. Due to Covid-19 the Humboldt State University class, Engineering 215 - Introduction to Design, instructed by Lonny Grafman was given the job of creating ways to protect students from spreading Covid-19 when in person school is back in session.

Background[edit | edit source]

In the fall of 2020, the idea of going back to school of spring 2021 was under much controversy within six rivers charter school. Some wanted to go back to school and risk spreading covid-19 while others wanted to be safe and continue online. Engr215 wanted to send the students back to school while also mitigating the risk of spreading covid-19. The indoor lab barrier was one of the needed protection methods in order for kids to go back to safety. Other projects included; Outdoor lab tables that promoted social distancing, Teacher protective stations, and a mobile protection station for theater class.

Problem statement and criteria[edit | edit source]

The Delphi Matrix proposed that the indoor lab protective barrier design Team REMS came up with would prove to be the optimal solution to the problem statement according to weight distribution. All Criteria: Covid-19 safety (CDC guidelines), instructor interaction, replicability, cost, aesthetics, and student collaboration were considered.

Criteria
Criteria Weight (0-10
Covid-19 Safety (CDC guidlines) 10
Instructor Interaction 9
Replicability 8
Cost 8
Aesthetics 7
Student Collaboration 6

Description of final project[edit | edit source]

The final project was created after going over safety guidelines, How covid-19 spreads, how teachers will interact with their students, and the learning environment for students. Multiple trial structures were built. All of the material was available on amazon so it is able to be ordered from the safety of your home. This structure is a 3 sided barrier with a base of 36'' by 36'' by 27''. Each side has a sheet of vinyl that protects the student. Photos and descriptions. Use gallery (https://www.appropedia.org/Help:Images#Galleries (Links to an external site.)).

Include a how to use and maintain section. See the how to template below.

Testing Results[edit | edit source]

The barrier holds up well. There is no need for the structure to be clamped to the table. Doing so would be for extra precaution. The barrier is made to be able to withstand chemicals that are used in the chemistry lab. It will not be affected by low heat nor the cold. It is made out of non permeable material. The angle bracket aluminum frame is very strong. This allows for long term use. Each joint has a bolt with a lock tight nut to avoid loosening over time.

How to Build[edit | edit source]

1
Figure 1: Tools needed for the build
Gather tools and materials
2
Figure 2: cut of vinyl
Using a straight edge and scissors, cut three 36”x27” pieces of vinyl.
3
Figure 3: sample cuts of aluminum angle
Measure and cut four 27” pieces of 1.5”x1.5” aluminum angle. These will be the upright corner pillars. Measure and cut one 36” piece of the 1.5”x1.5” aluminum angle. This will become the front bottom frame piece. They will be referred to as the “wide” aluminum angles in the following procedure. 4. Also cut five 36” pieces of the 0.75”x0.75” aluminum angle which will become the remaining pieces of the frame. These will be called the “thin” aluminum angles in the following procedure.

Figure 4: Marking spot to drill
Begin assembly of the left panel. Gather one 27” wide aluminum angle and two 36” thin angles and set them on the working surface. Set the wide angle on the surface with one lip pointing up. Line up the ends of the thin aluminum with the ends of the wide aluminum. Mark a spot to drill where both angles will be drilled through.
5
Figure 5: Hole through both aluminum angles
Now separate and drill through the thin angle on the dot. Then, re-align the two angles and mark the wide angle through the hole that you just drilled. Separate and drill the wide angle on the dot. Repeat this process for the right-side panel.
6
Figure 6: bottom corner of front panel
Begin assembly of the front panel. Gather two 27” wide aluminum angles, one 36” wide angle, and one 36” thin angle. Align one 27” wide angle with the bottom of the 36” wide angle. Mark a spot to drill where it will go through both pieces. Remove and drill the first piece. Realign and mark through the hole you just drilled. Drill through the second piece. Repeat for the other side of the panel.
7
Figure 7: front panel with all sides
Align the 36” thin angle with the open side of the panel. Repeat the process of marking and drilling with this last piece to create a 4-sided frame.


Maintenance[edit | edit source]

Introduce this maintenance section.

Schedule[edit | edit source]

This is when to maintain what.

Daily
  • The surface of the barrier will have to be wiped down after each student uses it.
Weekly
  • Spray down with windex to keep transparency of vinyl.
Monthly
  • Walk around and wiggle frame to make sure bolts are all still tight.


Yearly
  • Change out double sided tape if vinyl is peeling off of the frame.


Troubleshooting[edit | edit source]

Problem Suggestion
wobbly frame check for loose bolts
loose bolts tighten bolts
Falling vinyl replace double sidedtape

Suggestions for future changes[edit | edit source]

If a cheaper frame is desired would could be used. The method of building would be very similar.
