Idiot proof

Idiot proof was a design or system that was so simple and foolproof that it could be used or understood by anyone, regardless of their skill level or intelligence.

When Data touched the panel of a Type 7 shuttlecraft which brought a Picard doppelgänger aboard, sparks flew out of the console. He mentioned that the polarity may not be compatible and asked for a variable phase inverter. Geordi La Forge also added the fact that it was not possible, and the connection was idiot proof. (TNG: "Time Squared")
