Burn-in contacting that holds: why force curves belong in the cam geometry, not the operator's wrist

A burn-in strip that needs uniform high force cannot depend on how hard an operator turns a lever. Reliable, repeatable clamping comes from engineering the force ramp into the cam-track geometry itself — rising to the target load, then holding flat in a self-locking region. This piece explains the principle behind the self-locking lever-cam mechanism (EP3023801). (Full article to follow.)
