Claim 19:
20. A transformable knob for a vehicle comprising:
an axle extending along an axis;
a body mounted to the axle and rotatable about the axis, with the body comprising a face plate and a periphery wall coupled to the face plate and extending around the axis, with the face plate and the periphery wall defining a cavity, and with the periphery wall arranged to flex relative to the axis;
a plurality of engagement arms disposed within the cavity and movable toward and away from the axis, with the plurality of engagement arms configured to selectively engage and flex the periphery wall between a first configuration and a second configuration;
an actuator in engagement with the plurality of engagement arms and arranged to move between a first position and a second position, with movement of the actuator between the first and second positions facilitating corresponding movement of the plurality of engagement arms to flex the periphery wall between the first and second configurations, respectively;
a guide plate; and
an electric motor coupled to the axle and configured to rotate the axle about the axis;
wherein the plurality of engagement arms are configured as plurality of plungers each individually engaging a portion of the periphery wall;
wherein the actuator extends along a first plane orthogonal to the axis and defines a first track extending in a curved radial configuration from the axis, wherein the plurality of engagement arms comprise a first post disposed in the first track, wherein rotation of actuator moves the first post within the first track and correspondingly moves the plurality of engagement arms between the first and second positions;
wherein the guide plate extends along a second plane parallel to the first plane, with the plurality of engagement arms disposed between the actuator and the guide plate, wherein the guide plate defines a second track extending in a straight radial configuration from the axis, wherein the plurality of engagement arms comprise a second post disposed in the second track, and wherein the guide plate is stationary as the actuator moves the engagement arms between the first and second positions to guide the movement of the engagement arms in linearly towards and away from the axis;
wherein the guide plate is fixed to the body and the guide plate retains the rotational position of the engagement arms relative to the body as the actuator moves the engagement arms between the first and second positions;
wherein the axle is fixed to the actuator; and
wherein rotation of the axle by the electric motor moves the actuator between the first and second positions.
