Working with industrial power tool leader, Ingersoll Rand. Redesigned their flagship product the 2235 Pneumatic Impact Wrench from the ground up_

Research and Ideation occurred in this process in parallel, influencing one 

another-seeking the most balanced design direction.

The on the ground research was a vital part of the process. Meeting with mechanics I learned about the ergonomic woes that existed in the current
design. I learned about what they liked and did not like.

The refinement phase is all about visualizing the surfacing and slowly ideating what exists to find your final form. At first the refinement existed in the foam models created one after another, the green foam models are early rough models where the white foam models are the refined
directions. After the white foam stage, a combination of the two white foam models was merged into a design direction. This direction was further refined using the 3D software Rhino3D. This allowed me to refine the surfacing quickly through a multitude of 3d models.

Ergonomic design shaped this project. In order to maximize usability and comfort, a textured grip was designed into the handle. Accompanying the handle grip, a top grip was incorporated into the top of the product. Holding the wrench by the handle and top grip will increase support for difficult actions. A flat was sliced into the side of the titanium front providing extra surface area to grab. Holding the wrench by the handle and the front increases precision. Having the ability to switch grip types depending on the use case increases usability.
