Hoxton Analytics

Hoxton Analytics is a company that creates sensors to count people and monitor occupancy using artificial intelligence. This is done using cameras to capture data from feet and understand behavioural trends. They approached me to understand how they could house their hardware in a low-profile manufacturable case.

It started with a simple sketch where they could explain the needs for the product. We then made a quick diagram for dimensions and specific functions. It had to hold a unique camera filming at a certain angle and block out window reflections and peripheral video noise.

I then made a CAD file in Autodesk Fusion 360. This would hold the camera in the same position for repeatable future designs. I also incorporated tabs for countersunk flat head screws to secure the lid to the box. I 3D printed the prototype using polylactic acid filament. There were two parts (lid and case) and it worked well for the first camera iteration.

On the second iteration the hardware became more compact and specific uses changed depending on the desired function. For example, the low foot angle was different than the overhead version.

I made a quick cardboard case that would be used to understand dimensions. I needed to factor in the best use of space and how it would attach to the wall/ceiling.

I then made a model and created it on my personal printer. This version has the exact chamfered angles needed for the camera viewport, and clip in slots for the Raspberry Pi board.

It uses tapped threads for replacing parts and the ability to remove the lid multiple times. There is also a reset hole button that threads in perfectly to the lower corner.

The design took in considerations of weather, strength, and being able to blend into its surroundings. After testing the prototypes in the field, the company has manufactured many camera cases using sheet metal bending. The outcome has been a profitable startup story showing the process of early prototype through to final functional design.
