No problem is too small to be inspired by, and no form too simple to be a solution.
In this case the starting point was a tiny frustration that many have experienced without really noticing, the tissue that doesn't pop up. Savoring the frustration, I ripped open the box and began to study tissue dynamics. After a few seconds of play it became obvious that for one tissue to follow another consistently, a slight pressure is needed on the tissues to engage the folds. In a less-than-full box there is no pressure, thus the typical failure.
I pressed on the tissues in various ways with my hands and began to imagine an object resting on top of the stack, applying a constant pressure. I sketched a few possibilities. Most involved a box with a floating top to rest on the tissues. It wasn't until I built the first model that I realized the box was completely unnecessary.
Because the box is no longer necessary for dispensing, Toro suggests the possibility that facial tissues could be sold differently in the future. Packaged in bulk, as hand towels are in commercial settings, tissues could be restocked as needed, without individual boxes to throw away, resulting in less waste.
Instead of covering an ugly box with a less ugly box, as most tissue dispensers do, Toro presents the pleasant qualities of the material inside. Function is improved, since the gravity-applied pressure is always the same. Any discontinuity in the flow of tissues caused by a misfold at the factory is easily restarted, since everything is visible. And visibility means it's impossible to run out unexpectedly.
