After our presentation on the prototype of our product, we happily found that Huang Ayi really love the trailer we made for her and it is functioning well! We tried to test the stability of the trailer by filling the bucket with water. And the result shows that the trailer is able to support the weight of the bucket and moving smoothly without pouring water out.
We've also made an interview to know more about Huang Ayi's experiences and feelings on using the prototype. Here is the written record:
Interviewers:
Kevin & Emily
Interviewee:
Huang Jiu Hong Ayi
Q: Do you think we achieve the functionality of it?
A: Yes! Yes! (Huang Ayi slides the trailer) It is very smooth, and it can bear the weight of the bucket, it is very smooth sliding the trailer.
Q: Do you like the material we choose -- a blend of wood and HDPE plastics?
A: Sure, it is very smart of you. I once saw you two were sanding the plastic wheel, I saw how much you devoted to me, I am so grateful.
Q: In which way do you usually hold the handle or how can we fit the handle on to help you hold it more conveniently?
A: The handle should change. Since I usually pull the trailer on one of its sides but not pulling in front of it, I think you can redesign the handle like that. (Huang Ayi showed us with her gestures)
Q: Do you think we need to increase the smoothness of the wheel when it’s turning in different directions?
A: I think it is already smooth enough! It is good, it is good. (Huang Ayi tested the prototype again)
Q: Do you think the size of the trailer is too big or too small? Will the trailer take up too much space for you to rest in your room?
A: No, I don't think so, it is not that big, so it will be totally okay.
Q: Final question, will you show the trailer to Ayis on other floors?
A: (Laugh) I will, I will tell them it is the students on the 8th floor made for me, I will be very proud.
Future Improvements
Basically Huang Ayi is quite satisfied with our prototype. We asked about her preference and requirement on installing the handle, she illustrated that it would be better if we can redesign it by pulling the trailer on one of its sides. In this case, we will re-sketch the design for the handle and think about use other materials than wood to make the handle.
