Top 5 Constraints – Bear Spray Light

My bear spray light is a project can be designed many different ways, which is why I want to define 5 constraints to help hone in this project. One of my five constraints for my final project will be the aesthetics. I want to incorporate Art Deco and Organic aesthetics of design for the lights.

My second constraint will be that it needs to be small enough that the bear spray contraption can still fit in your backpack side pocket or even hook onto your jeans.

My third constraint is that the light fixture needs to use batteries that can be found at normal convenience stores, such as Wal-Mart or Safeway.

My fourth is that my light fixture needs to have three different light settings. In my mind, these will include a bright light straight ahead, a light that encompasses 180 degrees and even a red light. My idea for this comes from your typical head lamp. A picture of this can be seen in Figure 1 below.

My last and final constraint, for now, is that my project is durable. I don’t need fragments of glass breaking easily when you are already flustered if you see a bear!

    This is an awesome idea Emily! I am reading through your constraints and you seem to have it all figured out. As I read through them, I am wondering why you want the lighting to be round and bubble shaped. Does this have something to do with the bears or is it just an aesthetic style? I also like that you thought about the different supplies you will need and the cost that might take place. This project seems very complex, but awesome. Keep it up!
