Paintball Design Project Ideas

Hi, I'm currently a senior Mechanical Engineering student and this year we have to begin our senior design project. I was looking for some ideas related to paintball guns, milsim, woodsball, etc. We must put forth the money for the project or we can borrow money from the school but then they can keep the project so I'd prefer not too. So, preferably not "too" expensive. It also doesn't have to be a Tippman exclusive thing either (ex: better paint grenades), just figured I'd start here. Any ideas appreciated. 

Better pods.

A hyrdration system, light weight, compact. descrete.

A shade system incorporated into the mask.

I am sure i can come up with more...

Some kind of locking, telescoping stick squeegie.. would be awesome.
It can squish down to fit in a pants pocket, but lock open to use with any barrel.

Hinged would be too fragile, and one that come apart runs the risk of losing one of the pieces.
