The problem

On a factory floor there’s often nowhere to set a laptop down. Engineers doing co-ops and internships end up working standing over a machine, balancing a laptop on whatever’s flat, or not having a surface at all. Market research with interns confirmed it wasn’t a personal complaint but a widespread gap, and that’s what the project set out to close: a work surface that mounts to the structure already on the floor and folds away when it isn’t needed.

Requirements before geometry

The requirements came from the users, not from us. Scoping interviews with interns fixed the targets that then drove every design choice: it had to hold real weight, weigh little enough to mount and stow by hand, deploy fast and one-handed, and attach to the mix of Unistrut, aluminium extrusion, and beams that industrial environments are actually built from.

Those targets became numbers. The prototype carries 10 kg at a 2 kg unit weight — a 5:1 load-to-weight ratio — and folds out one-handed in under four seconds.

The SolidWorks assembly: a work surface hinged off a Unistrut channel, hook sheets setting the height, and a latch to fold it flat when idle.

How it works

The mount is a length of Unistrut channel that fastens to whatever structural element is nearby. Two hook sheets ride the channel, letting the surface be pinned at different heights for standing or sitting; a machined carriage carries the hinge and the load into the channel; and a latch holds the surface folded up against the channel when it’s out of use, so it doesn’t eat floor space.

The mechanism in one sketch: the hook sheet sets the height, the carriage carries the surface, and a pin ties them together.

The deploy motion in CAD: stowed flat against the channel, then folded out to a level surface — the sub-four-second one-handed action.

The carriage is where the load actually goes, so it was the part that got the analysis. A free-body diagram of the carriage — distributed load across the surface, reactions at the pin and the hook — sized the bracket and its joints before anything was machined.

Building it

The team iterated four design generations toward the reliability targets, then built and demonstrated a medium-fidelity prototype — machining the carriage and mount hardware and assembling it into a working unit.

Outcome

The prototype met its load, weight, and deployment targets and demonstrated the core idea: a surface that clamps to the structure already on the floor and disappears when idle. My role was on the design team, contributing to the mechanism and the build. The lesson that carried forward is that the requirements were the design — the 5:1 ratio and the four-second deploy came straight out of the interviews, and hitting them was mostly a matter of not losing sight of numbers the users had already handed us.
