Parsyl

A ruggedized cold-chain shipping tracker built to survive tough shipping conditions and to be readable at a glance by warehouse staff anywhere in the world.

The Brief

Parsyl was launching a shipping tracking platform for perishable cargo: vaccines, biologics, fresh food. The tracker had to hold up to extreme conditions in transit, but it also had to be foolproof for handlers across dozens of languages and literacy levels.

Constraints

IP67 sealing and operation down to -40°C drove the housing geometry and the seal architecture. The device needed to be attachable by zip-tie, sense lighting conditions, and be visually customizable for a variety of applications.

Direction

A small, single button device with an on/off slider and a 360° light pipe, which was readable from any angle at a glance. The form is intentionally generic enough to live in any logistics environment without standing out, but distinctive enough that handlers learn to recognize it.

Form & Iteration

We worked the device down through several housing iterations to balance internal stack-up against the IP67 sealing surfaces. A pill shape was chosen to minimize internal space around the coin-cell battery and to fit comfortably in the hand. Iterations on label form and placement were ultimately reduced down to a single QR code for flexibility.

CMF

A polished white main body with customizable removable colored base sleeves allow the product to remain both neutral and customizable for easy distinguishability in the future.

Engineering & Production

Beyond ID, we acted as Parsyl's product engineering partner through production, delivering final CAD, technical drawings, and DFM reviews that accounted for sealing strategy, wall thicknesses, draft, moldability, and tolerances. The final enclosure is a double-shot case with an overmolded button gasket. The two halves are ultrasonically welded together and the final bottom cover is glued on.

What Shipped

Parsyl publicly launched in 2018. The Trek tracker line went on to be used in vaccine cold-chain monitoring including UNICEF and WHO supply programs.
