This semester, In product design, we designed a handheld device to detect the sense of smell. My prototype contains a sensor, screen, buttons, and a handle. How it works is that when the device is activated with the controls, the sensor will detect the smell and the internal machinery will process the information. Finally, the data will be displayed on the screen either with an image or text. Overall, I think my device turned out the way I wanted it to.

Found Poem:

Poem explanation:

This poem was created with the word in the short story, “Fish Cheeks”. The main conflict in this story is Character to Self because the narrator wants to be more American and is embarrassed by her culture. After her family invited her crush over for a Chinese tradition Christmas dinner, she felt miserable and doesn’t like the way her family members act toward her American crush. Which is why I added verbs like “reach” “dip” and “lick” in the poem. But after many years, she understands her mother’s word; “your only shame is to have shame” which is also included in the poem. Overall the poem identifies the conflict and leaves the conclusion and theme a mystery.

As Project Collision shifted due to the Covid-19 virus from a collaborative school project to an individual home project. Some big challenges that I faced were lack of communication and materials. At first, I was very stressed and didn’t know what to do when facing these problems, but eventually, everything works out fine and I was able to get back to work as normal. To overcome these challenges, I connected with other students by creating a WeChat group where we can help each other when needed. And for materials, I found some substitutes at home to replicated my original plans. Before this project, I used to think that testing wasn’t that important, and I should just design and create with my original plans. But now I think testing is a crucial part of making something because it allows you to improve more and more throughout each design. For example, when we just started brainstorming ideas for the parachute, I thought that the 48cm (diameter) parachute was the best and I should defiantly use it for the final design. But after some testing, I found out that the 48cm (diameter) parachute was too small and couldn’t provide enough drag for the package, so I used the 58cm (diameter) parachute instead.   Looking back on project collision, I learned that using data to support my decisions was very important. Mainly because it allowed me to make the most accurate and the best decision that is proven by facts. One area where data supported my thinking was when I decided to use the 58cm (diameter) parachute for my final design. I choose the 58cm (diameter) parachute because data shows that it provided more drag and made the package fall slower than all the other parachutes I made. Without data, I might have chosen the 48cm (diameter) which would have turned out a lot worse.

Project collision part 4:

Currently, my team and I are trying to make the parachute prototypes, but due to the coronavirus outbreak, school got canceled, causing a lot of difficulties for us. Even though coronavirus is causing us trouble, we, Techincal, will still design and make a parachute that will allow our package to land softly and accurately, and my job is to design and make the best suitable size of the parachute to secure a slow, soft landing. Due to coronavirus, we now have limited materials and also need to create a different texting platform that we can access from home.

Testing procedures:

The image above shows our testing procedures from FA space, but currently, we cannot access that space, so we might have to collect data differently at home.

Data table:

Unlike the procedures, our data table will stay the same.

Prototype 1:

1x plastic parachute canopy

8x red strings

1x spill hole

1x green paper box

Due to a lack of resources, this design is different from our initial design. The box is in different sizes and is lighter than the original box, because of this, the parachute was also made to be smaller. For strings, the material and length of each string is different from the initial design, but the number of strings stays the same.

Project Collision

Have you ever wondered why the package you order still hasn’t arrived? Or why you need to pay shipping and delivery fees? Well, it turns out that your package goes through a lot of processes before it can arrive at your front door, which not only takes a long time, but it also uses up a lot of resources, causing the shipping fee to cost a lot of money. But nowadays, company like zipline or flirty is trying to make this process easier, cheaper and faster with the help of drones, these company is planning to drop the package from the drone at around 8 to 10 meters above ground, and our goal of is to make sure the package delivered from the drone will land safely.

One way to make sure the package can land softly and accurately is to make a parachute, which is what my team and I are trying to design. My job is to find the best suitable size of the parachute to secure a slow, soft landing. And to achieve that goal, I need to decrease the speed of the fall. But to understand this, we first need to talk about how a parachute works. Parachutes can be commonly found in the sports of skydiving; when a person jumps out of a plane at a high altitude and starts falling at high speeds because of gravity. Then, the skydiver would open a parachute that would help the skydiver slow his or her way down and break the fall, allowing him or her to land softly and safely. But what is the parachute doing to stop slow the fall down? The parachute slows the fall by catching air and creating air resistance with its surface area to counteract gravity, this is also known as drag. This means that the larger the parachute, the greater the drag force (according to Scientific America).

But before we start designing our parachute, we tested our box without any design to collect data so we can compare it to our future design. That way, we can tell if the design is effective. These are some of the data we collected on the first drop:

Average speed 2.991725m/s

Slowest speed 0 m/s

Fastest speed 9.5702969m/s

Accuracy of landing 25cm off-target

Accuracy of its final destination 1m off-target

The side it landed on Topside

The side where that it ended up with Right side

With the data we collected, we can now see what we need to improve on. One of my most important goals is to decrees the speed of the fall to at least 2 m/s, or the impact will destroy the package.

Our goal is to protect our package from an 8-meter fall, and my key question is what the perfect size of the parachute is to decrees the package of the speed and reduce the impact before the package hits the ground. And my next step is to design and make the perfect sized parachute.
