The link above leads you to my final product!
My primary purpose in making this product was to aid Sodexo workers that worked on constructions during night time. According to sources from the United States, there was a total of 5,147 casualties caused during night constructions and on average, more than 99 a week gets injured during these nightly constructions. Although this is my personal opinion, these casualties are caused during night time constructions as there are possibilities of missteps and unawareness of one’s surroundings. I believed that it would be nice if they could get access to a portable and easily made torch so that they could prevent accidents from happening. Also, I believed that if there were to be numerous casualties or injuries within in school campus due to nightly constructions, that would then lower the school’s reputation as a safe learning environment. By targetting out SODEXO workers, I have faith that we could start the flashlight campaign locally and then expand it for more public purposes.
I have also had several conversations with some SODEXO workers about whether they feel secure when the work in the constructions during night time. Although most of them simply chuckled and said that it was no big deal and that the work spot was quite safe, some reported to me that it gets slightly frightening as some of their friends sometimes drops tools from heights that can cause serious injuries. Although this may seem like a minor problem, I believe that if we solve this problem, we could have to make a great impact on the school as well as society.
By looking at my hand wind flashlight, I can tell that it works and serves its purpose for lighting the dark. However, what I have found less appealing was the fact that the LED light wasn’t the strongest it could have been and only lit up a small amount of space in the dark. Also, my science teacher Mr. Toigo remarked that the product could have been more successful if I made the handle swifter and more comfortable to rotate. He also commented that I could have improved the aesthetics of the torch by covering the entire surface of the torch. However, I didn’t make changes for the last advice as I believed, that space will enable the users to replace any parts of the flashlight that are malfunctioning. For example, the LED light may have lost its connection to the hand wind generator which would hinder with the lighting of the bulb. Overall, I am pleased with my product as it matches the design that I have picked at the beginning of the project. What I believe I could have enhanced, however, was the fact that it wasn’t the most original idea that could have been made. Maybe I could have added a cool new feature to the torch so that the idea would be more original.
How the product works is that hand wind generator works as the power source of the LED light and the connection between them allows the kinetic energy generated by the user to be converted into electric energy within the bulb. What is crucial in this process is that the hand wind generator has a limited amount of energy that it could generate no matter how hard or fast you rotate the handle. This implies that it has a limited amount of voltage that it could supply a bulb; which is why I chose a small LED light instead of a big bulb.
I believe that if this product is used carefully enough, it is definitely sustainable and that it is incredibly purposeful for my target: night workers. It is also highly functional and rather durable due to the tensile material that I have utilized (wood and plastic). There are no particularly sharp bits or small bits within the product which eliminates the probability of cut or choking hazards. However, what I could consider doing in the future is to glaze the wooden popsicle sticks as they may get splinters as they age. Although this product is partially made of plastic, I believe that this product is environmentally friendly as it mainly used from recycled materials (eaten ice-lollies and empty water bottles). As for long term environmental impact, maybe the concept of recycling implemented to this product will spread this positive concept and help the environment.
For grade 8 students that are taking this course next year, I definitely recommend making this product as it is of adequate difficulty and the materials are easily accessible through the laboratories and school storage. I definitely had fun during this project and I wish we can do something like this again someday 🙂
