The concept of a supermarket that can be replenished from behind the shelves is a long-term goal that offers many advantages; customer are left to shop unobstructed and replenishment can take place during the day instead of at night. Of course there are also many challenges in terms of space efficiency and practicality that need to be explored.
This concept sketch shows how a fresh grocery display fixture that allows extra stock of trays to be replenished from a corridor behind the fixture. The trays can then be drawn forward easily from the front when the empties are removed.
