Research – Nodes

These blogs showed how to create snug joints through the use of nodes. “Nodes are little bumps located in the slots or on tabs in your product that are there to help compensate for material thickness variations. This idea is they compress when a product is assembled providing friction at points rather than along the whole surface of the slot. This means the slot can be fractionally wider at the opening allowing the pieces to be slotted together easily but still create a snug joint.”

The site suggests that it is  best to have symmetrical nodes- on both sides of the slot, using a gentle curved shape node and the longer the node the gentler the curve and the easier it is to slide on and off.
