“Can’t we find something faster than a measuring tape?”

A customer approached us with a problem. Their fulfillment centers were being inundated with new products that needed to be measured, weighed, scanned, and entered into the system. 

Most of this was being done by hand, and in addition to the cost in person-hours, the amount of manual data entry was creating errors that made automating packaging very difficult. 

We were asked to propose a solution that would streamline this process. 

 
 

My first thought was to build the station from a set of welded square pipe components and a sheet metal load plate covering an existing scale.

 

I knocked together this little 3D printed model to demonstrate how easy to pack and assemble this scheme could be.

 
 

After reaching out to some of our usual vendors, it became apparent that welding would break our schedule, so we started to transition to aluminum extrusions. 

 

We added a barcode scanner and tablet interface. After looking into the certification process for getting even minor chances approved for a NTEP scale, we ditched the load plate and just used an off-the-shelf unit. 

 
 

Several last-minute changes lead to another round of radical simplification. I modified the camera support to telescope upwards, allowing us to dimension larger objects. 

 

After delivering the initial six units for field testing, we sat back and waited for the first round of feedback.

Our users requested that we make the system more durable and easier to maneuver around a fulfillment center. 

 

In response to the first point, I decided to explore structural foam molding. This process is common in industrial products and can circumvent some of the usual design constraints of traditional injection molding. Structural foam parts are very tough and can be produced pre-colored, textured, and ready to assemble. 

 

To make the station easier to maneuver, I decided to give it a collapsable hood. This change also allowed us to build in an edge-lit LED panel and stow the WiFi router at the top of the system.

 
 

After some input from the sales team, we decided that the cost of tooling would be too great for the initial run of our new stations, so I converted the design back into aluminum extrusions. 

 

We took advantage of the redesign to replace the off-the-shelf scale with four load cells supporting an aluminum plate with our pattern pad printed onto it. 

 

I added fold-up tables on either side because some of our testers had reported needing to use a laptop in conjunction with the system and wired an outlet for charging phones into the electrical system. 

 


This version is currently undergoing testing.
