Abstract
An apparatus for a wearable device including a locking mechanism for components of the wearable device is described. A wearable ring device may include a ring-shaped housing configured to house one or more sensors configured to acquire physiological data from a user, and a flexible printed circuit board (PCB) including electrical circuitry for the one or more sensors. The wearable ring device may include one or more locking grooves disposed within an interior surface of the ring-shaped housing, the one or more locking grooves configured to receive the flexible PCB and maintain a gap between an inner circumferential surface of the ring-shaped housing and a first surface of the flexible PCB.
Core Innovation
A wearable ring device includes a housing configured to house one or more sensors configured to acquire physiological data from a user, the housing comprising an outer housing and an inner cover coupled with the outer housing. The inner cover comprises one or more apertures, and the one or more sensors are disposed at least partially between the outer housing and the inner cover so that the sensors are aligned with the apertures.
The wearable ring device further includes a flexible printed circuit board comprising electrical circuitry for the one or more sensors. One or more locking grooves are disposed within an interior surface of the outer housing, where the locking grooves are configured to receive the flexible printed circuit board and maintain a gap between an inner circumferential surface of the outer housing and a first surface of the flexible printed circuit board.
The locking grooves extend around only a portion of a circumference of the outer housing and are configured to position the flexible printed circuit board in a defined radial orientation relative to an axis of the wearable ring device. In this configuration, the one or more sensors are aligned with the one or more apertures of the inner cover.
Claims Coverage
The independent claim covers a wearable ring device with sensor alignment between an outer housing and an inner cover using locking grooves that receive a flexible printed circuit board while maintaining a defined gap and defined radial orientation; the inventive features are directed to mechanical retention and positioning of the flexible PCB and alignment of sensors with apertures. The partial content also indicates dependent claim refinements that further specify additional gap materials, wireless coupling, static electricity reduction, and optical light transmission.
Locking grooves receiving flexible printed circuit board with maintained gap
One or more locking grooves disposed within an interior surface of the outer housing are configured to receive the flexible printed circuit board and maintain a gap between an inner circumferential surface of the outer housing and a first surface of the flexible printed circuit board.
Defined radial orientation positioning for sensor alignment with apertures
The one or more locking grooves extend around only a portion of a circumference of the outer housing and are configured to position the flexible printed circuit board in a defined radial orientation relative to an axis of the wearable ring device such that the one or more sensors are aligned with the one or more apertures of the inner cover.
Housing with inner cover apertures and sensors disposed between outer housing and inner cover
The wearable ring device includes an inner cover coupled with the outer housing, where the inner cover comprises one or more apertures and the one or more sensors are disposed at least partially between the outer housing and the inner cover.
Flexible printed circuit board electrically coupled to sensors
A flexible printed circuit board comprises electrical circuitry for the one or more sensors.
Overall claim coverage centers on a wearable ring device where locking grooves in the outer housing mechanically receive a flexible printed circuit board to maintain a housing-to-board gap and to position the board in a defined radial orientation so the sensors align with apertures in an inner cover.
Stated Advantages
Maintains a gap between an inner circumferential surface of the outer housing and a first surface of the flexible printed circuit board.
Positions the flexible printed circuit board in a defined radial orientation relative to an axis of the wearable ring device.
Aligns the one or more sensors with the one or more apertures of the inner cover.
Insulating material in the gap supports insulating and shock-absorbing properties as described in the partial content.
Antenna elements in the gap are configured to wirelessly couple one or more components with a user device as described in the partial content.
Flexible and electrically-insulating protrusions interface with locking grooves to reduce or eliminate static electricity buildup as described in the partial content.
Transparent epoxy material in apertures enables light emitted by the sensors to pass through the inner cover as described in the partial content.
