In the meantime, it’s been another long and exciting week in the world of the Coolest Cooler Engineering Pilot, where we continue to push and refine the Coolest into its final polished state.

Every day starts with a clear plan around which factory we’re visiting and what we hope to tackle, then a debrief on progress made over the previous 24 hours. We check to see who’s waiting on what feedback and apply pressure to any bottlenecks. Easier said than done, but not by much because we’re all focused on the same two goals — to make certain the Coolest Cooler lives up to it’s name, and get into full production ASAP.

Here are some of the details we sweated this week:

1. Trigger pull. Because you never want to accidentally turn on a blender, especially with your butt, we designed the ‘ON’ switch with a horizontal trigger switch that you pull to activate. We tweaked the internal design to make it easier to assemble, changed spring length and tension to give a better feel for the turn-on, and relocated a tooling gate for a better surface finish.

2. Your Coolest comes with four color-matched plates that were originally planned to be made from high density polyethylene (HDPE). We felt it was a bit too soft, scratched easily, and might bend if you put them in a dishwasher. So we switched to a food-grade polypropylene (PP). They also make awesome flying disks!

3. Some things don’t become obvious until you touch them. While we were fine-tuning the width of the divider, we uncovered a design flaw. We originally planned for the divider to go all the way to the top of the Coolest, but we realized that if you pulled the divider out and tried to put it back in place with any ice left inside, at least one ice cube would inevitably end up blocking the path. We adjusted the height down by 1/2” and now the lid will still close even if a stubborn ice cube tries to interfere.

4. We also made progress on all manner of packaging, received some new speaker rubber housing samples to evaluate, and test-rolled the tires in the new durometer. More details coming next week!

Hope you all are enjoying the EP progress as much as we are, and please let us know what else you’d like to hear about in the comments here. Thanks!
