Claim of US Patent No. 10,485,115

1. An electronic device, comprising:a first device housing and a second device housing;
a hinge coupling the first device housing to the second device housing, the first device housing pivotable about the hinge relative to the second device housing;
one or more springs; and
a flexible display coupled to the first device housing and the second device housing and spanning the hinge;
wherein:
one housing of the first device housing or the second device housing defines a curvilinear recess causing the flexible display to define a service loop, the service loop comprising a hemi-cardioid contour defining a convex lobe extending to a bifurcated distal cusp, when the first device housing and the second device housing pivot about the hinge from an axially displaced open position to a closed position;
a first portion of the hemi-cardioid contour disposed to a first side of an axis bisecting the bifurcated distal cusp defines both a convex contour and a concave contour abutting the curvilinear recess;
another housing of the first device housing or the second device housing defines a linear recess into which the flexible display is positioned;
a second portion of the hemi-cardioid contour disposed to a second side of the axis bisecting the bifurcated distal cusp defines a linear portion extending distally from the convex lobe;
the service loop becomes planar when the first device housing and the second device housing pivot about the hinge to the axially displaced open position from the closed position; and
the one or more springs bias the first device housing away from the second device housing when the first device housing and the second device housing pivot about the hinge to the axially displaced open position from the closed position.
