Assignment 7
- Experiments
Document your experiments and findings on creating your new material. How can you make it perfect? What are the techniques that you can use to create an object out of your new material? Master the technique you want to use and document your failures and successes in your journal.
Project Title: five minutes
Through our own observations at Sproutworks and conversations with the staff at Sproutworks, we find they are content with the process at the cafeteria and don’t necessarily want change. However, in terms of the staff’s welfare, there are some areas for improvement. Staff work from early morning to around 8 pm. They will have two or three hours free in the afternoon (around 2-4 pm), but for the most part of the day, they are constantly busy. And for each meal prep and service i.e. breakfast, lunch and dinner, they are only allowed five minutes of break in each of the more than three hours of working time. We saw a few stools next to the counter that allowed them to rest for a few minutes. But without back support, it can not be called a comfortable chair for rest. We decided to create a portable and adjustable backrest for stools. When the backrest is not in use, it will be folded down so it won’t look obtrude in front of the food counter. The back material will be made from presses of plastic bags and foams. And the stem, the structural part will use wood with plastic connection points.
We have experimented with the main backrest’s material but we still need to experiment with the material for the stem part of the backrest. We are also trying to finalize the mechanism and the design by the end of next week.
In the experiment, we tried plastic and plastic with foam. For the plastic, we collected all the plastic bags from our friends and classmates, however, most of which we collected does not have a clear label about their type on them. This makes our usable material much less than we collected. We picked up all plastic bags labeled as 2, following the instructions given by the guest speaker in the lectures, we heated them up at the temperature of 160-celsius degrees. 10 seconds each side, however, since we put several layers together, we found it hard for us to make them sticky to each other within only 20 seconds (10*2), therefore, we put our materials in the pressure machine, again and again, each time 10 seconds, and check the results each time. However, after 6 times of this repetition, we found out that our materials shrink, what is worse, they are still not sticky enough, which made us frustrated. Then, we added some foam inside the plastics and repeated the same work. Not only did our material softer, which is good for our project–back support, but it also made plastics be more sticky to each other. We were really glad about our finding until we acknowledged the fact that foam should not be heated, since heating it will make it no longer recyclable. Then, we searched on the website about how to make plastic more soft and flat. And we found out that it might be better if we heat up one layer of plastic one by one, and then heat them all together. We are going to try this technique next week.
- For the 2nd round of meeting with CP
Group work: document the meeting. Do a debrief afterward. Create one blog post as a group and submit the same post in your journal.
Individual work: use the 4Fs: Facts, Feelings, Findings, Future method to reflect on your experience working with CP so far. See Chunhao’s example below. Upload on the blog.
Meetings with Sproutworks Staff
Facts:
- Long work shifts; Long working time
- They feel like they are just doing a job, which is not that burdensome.
- Having limited places to rest
- Long preparation time between shifts
- People throw metal cups in the trash bins
- Too much tissue waste
Feelings:
- Shocked by their long working hours
- Shocked by the fact that they need to spend so many hours preparing the food and cleaning the table
- Previously thought they only work in the meal hours
- Show more respect for them
Findings:
- They have only one cold meeting room to rest
- The soft sofa is outside their workplace, and they are afraid of people seeing them relaxing
- The only place they can take a rest in their workspace is the four stools.
Futures:
- Put the metal cups back in the recycle places
- Reduce food waste
- Classify the wastes correctly
- Reduce the tissue waste, only take the amount that I need
Besides all of these, since we did not have a mature idea in mind, we decided to go downstairs and asked more questions towards the staff during the lecture. However, this unexpected conversation made some of them uncomfortable, feeling embarrassed, awkward, etc. We have learned that service-learning is not only about designing something for them but more importantly, we need to build a closer connection with them in order to know more about them, so as to design things that are really helpful for them.
