Mechanical & Hardware Design
I design and build physical things: mechanisms, enclosures, printed and machined parts, and the electronics that go inside them. I work in Siemens NX, Creo, SOLIDWORKS and Fusion 360, and I print, laser cut, mill and turn my own parts rather than handing a drawing over and hoping. Detailed CAD modelling is something I genuinely enjoy and keep doing outside of work, the reconstruction below started as a spare-time exercise in getting surfaces and transitions right.

Tolerance-driven mechanism design
A slotted crank mechanism with a 5/8 gear reduction converting rotation into controlled translation, designed to a tolerance scheme and then built and measured in order to check whether the scheme survived real manufacturing variation.

Off-grid wayfinding light for festival campsites
A three-module off-grid light pillar built from recycled zinc drainage pipe, which runs 48 hours across a 7-day festival on one charge, sets its own colour by GPS in order to match the festival's zone map, and installs by an untrained volunteer with an earth drill. This lands at 156–269 DKK per unit at 1,000 units.

About
I am Patrick Guldager Heen, a Product Development Engineer with an MSc in Design & Innovation from DTU. I work from the requirement to the tolerance scheme, and I test with the people who have to use the thing.
