> One Giant Misstep
> The vast majority of the complexity of the Press is driven by one simple problem inherent in the machine’s design: the massive force required to press the packs across the entire surface at once. The machine must apply equal pressure to ~64 square inches of surface area at once, meaning the drivetrain must be able to apply thousands of pounds of force to squish all that produce.
> On the contrary, when a human hand squeezes the same pack, we naturally use a very different technique [fingers create large amounts of pressure over much smaller surface area]
> I have to believe the engineers that built this product looked at other ways of pressing the juice, but if the primary mechanism could apply force in a more focused way it could easily save hundreds of dollars off the shelf price of the product.
That blog post is high art.
