Senior Project Questions

Here you go bioengineer

1) The main problem I have with my manual chair is the risk of falling forward when hitting a little bump on the ground due to the little front casters not being able to clear it. It's no fun being always alert all the time when wheeling outdoor knowing that I need to keep myself braced or I could possibly flip forward. Some paraplegics and quadriplegic might be able to do a quick wheelie to clear the bump but speed and incline of the surface are a factor when doing wheelies. It's not easy to pop a quick wheelie when going fast down a hill. I've seen people with big casters sometimes suffer with this issue as well. With the bigger caster the chair might clear the bump/hole but there's quick a bit of a jerk when it hits the bump which is enough to throw someone off balance. The reason I can't use bigger casters though is because when I had bigger casters, the front of my chair was slight more elevated which made my knees higher which didn't allow to get under 75% of tables. I'm about 6'3 so a pretty tall guy, which is why it's hard. I need to be able to get under tables when going to places like a restaurant, a friends house, etc. The needs of getting under stuff was greater than my needs of a bigger front caster which I wouldn't benefit too much from anyways. Oh we also did try lowering the foot plate but we couldn't get it low enough without being able to not scrape the ground.

2) I don't have a need to disassemble my chair ever so I don't have any input for this question.

3) N/A

4) I'm fine with how the chair is now (TiLite ZRA).

I've also done the survey
