Tasked with re-engineering a motorized product, I chose the rotary tattoo machine due to the stark contrasts between rotary and coil machines.
​
While coil machines excel in lining, shading, adjustability, and control, rotary machines gained popularity for their lightweight design, quiet operation, and low maintenance.
Motivated to create the best rotary machine possible, InkOptima merges the benefits of both coils & rotaries, in an ergonomic, multi-grip handle.
Top Grip
Bottom Grip

In longer tattoo sessions, or for lesser-abled artists, top grip relieves pressure points in fingers.
Bottom, or traditional grip relieves pressure points in the wrist & allows more detailed movement.

Artist Takeaway
“I don’t use rotaries because the lack of adjustability. I want to put out the best tattoo possible”

Through the Journey...
Ergonomic Quick Models


Lines & shading mock ups were presented to users to trace using a Play-Dough handle, molded to their preference.
Notes:
-
Very few similarities between study models; making mass manufacturing difficult
-
Righties & lefty handles must differ handles
-
Play-Dough made creating comfortable, unique grips quick & accessible





Inspired by the custom study models, I was led to incorporate InkOptima's personalized grip, utilizing soft, thermo-moldable ethylene vinyl acetate (EVA).
