ROTALIA
2023
A handheld tool to dynamically measure variable distances on curved or organic surfaces to allow the user to optimize their workflow
​
Utilizing a wheel with a three-inch circumference, the rosalia can measure distance in inches by mechanically tracking the revolutions.

MECHANICAL PRECENDENTS
Understanding that as a wheel is turned, units need to change in relation to it's revolutions.
​
• WATCH
Watch dial rotation changes date, rotations can measure units
​
• MECHANICAL COUNTER
Units change in increments as a gear is applied
​
• ROLLING TAPE MEASURE
As the wheel turns, the numbers change representing revolutions/distance the wheel travels
IDEATION 01
Mechanism​, Wheel size, Handles, User Interface
PROTOTYPING 01
Mobility​, Ergonomics, User interface​, Mechanical
FORM = ACTION
The form of the model was going to have to be influenced by the users experience and the mechanism inside
PROTOTYPING 02
After pursuing the watch gear mechanism to a finalized working prototype, a decision was made to start again with a mechanical counter.
​
ADVANTAGES OF NEW MECHANISM:
Smaller gear ratios, Precedent for mechanics, Higher digits, Compact
​
PROTOTYPING 03
Mechanical counter​, Understanding mechanism​, User interaction​, Gear ratios​, Reset mechanism​​
PROTOTYPING O4
Form informed by interior ​, View port​, User interaction, Starting point ​,Uni-directional reset mechanism​​
WORKING FINAL
As the wheel rolls, the 1.00's viewport rotates slowly in order to read the precise increments. As it passes 10, the next view port will turn 1/10th of a revolution and show the next increment.
