Opening force control for foldable electronic devices

Abstract:

A foldable electronic device includes a first portion, a second portion, and a hinge connecting the first portion and the second portion. The hinge is configured to allow pivoting movement of the first portion relative to the second portion, wherein the hinge has a hinge force. One or more magnets are coupled to the first portion, and a plurality of metal members are coupled to the second portion. Each metal member of the plurality of metal members is configured for individual removal from the second portion to define a magnetic force based on the hinge force, thereby allowing the first and second portions to be maintained together when in a closed orientation and allowing for easy one finger opening operation from the closed orientation.
