FIELD OF THE INVENTION
The present invention is directed to wearable electronic devices, and methods of use thereof. Particularly, the disclosure is directed to wearable electronic devices with at least one member formed to rigidly, semi-rigidly, and/or flexibly couple with a portion of the body of a user.
BACKGROUND
Wearable electronics are an emerging technology with many applications for the wearer. Often these wearables are intended to directly interact with the wearer's body to help monitor activity within the wearer's body. Sensors, input devices, or output devices in these wearable electronic devices often require proximity to specific locations on the user to perform the intended function of the wearable. Many of these wearables are manufactured to be formed on specific portions of the user's body by overlapping or partially overlapping said specific portion of said user. Often, these wearables require sufficient coupling strength or force to prevent inadvertent slippage or movement from the desired location on said user and therefore employ hard or semi-rigid materials. These wearables are intended to be worn for extended periods of time and during various activities. External forces may be applied to the wearable as the user interacts with physical surroundings. If these external forces are sufficiently high, the user may experience injury such as degloving. Degloving may occur when a watch or ring is hooked or snagged with excessive force which transfers the force into the body where the wearable is attached. Similarity, a person wearing a ring may incur a minor injury that elicits an inflammation response whereby the inflammation causes the finger swells against the ring, increasing pressure and restricting blood flow through the finger. In both causes, more severe injury is likely to occur due to the ridge materials used to manufacture these wearables.
SUMMARY OF THE INVENTION
This invention overcomes the disadvantages of the prior art by providing a wearable electronic device having at least one pre-formed stress point that is readily broken when subjected to an excessive external force, thereby causing the wearable to separate, preventing said force being transferred to the wearer.
In one embodiment, the wearable comprises a hard or semi-rigid member, an electronic device housed within, and a first axial pre-formed stress point such that the member will break at said pre-formed stress point when said member is subjected to a predetermined load.
In one embodiment, the wearable comprises a hard or semi-rigid annual member, an electronic device housed within, and a first axial pre-formed stress point such that the member will break at said pre-formed stress point when said member is subjected to a predetermined load.
In one embodiment, the wearable comprises a hard or semi-rigid member, an electronic device housed within, and a first radial pre-formed stress point such that said member will break at said pre-formed stress point when said member is subjected to a predetermined load.
In one embodiment, the wearable comprises a hard or semi-rigid annual member, an electronic device housed within, and a first radial pre-formed stress point such that said member will break at said pre-formed stress point when said member is subjected to a predetermined load.
In one embodiment, the wearable comprises a first interior bounding annual member formed of sufficiently low-strength hard or semi-rigid material, a second exterior bounding annual member formed of sufficiently high-strength hard or semi-rigid material, an electronic device housed within, and a first axial pre-formed stress point formed in said second member such that both first and second members will break at said pre-formed stress point when first or second member is subjected to a predetermined load.
In one embodiment, the wearable comprises a first interior bounding annual member formed of hard or semi-rigid material, a second exterior bounding annual member formed of hard or semi-rigid material, an electronic device housed within, and a first axial pre-formed stress point formed in said first member, a second axial pre-formed stress point formed in said second member, such that second pre-formed stress point is planarity aligned with first pre-formed stress point, such that when said first or said second member is subjected to a predetermined load, both said first member and said second member will experience material stress greater than the ultimate strength of said first member material and said second member material, causing the annual members to separate at the said first pre-formed stress point and said second pre-formed stress point, simultaneously.
In accordance with yet a further aspect of the present invention, the pre-formed stress point comprises a cross-sectional area of reduced material.
Further, the reduction in cross-sectional area may be formed with sufficiently small radii thereby selectively increasing localized material stress when said pre-formed stress point is subjected to bending forces.
The embodiments of the invention may be formed during the creation of the device, including but not limited to, forging, molding, stamping, and 3D printing. Further, the embodiments of the invention may be added during subsequent manufacturing processing, including but not limited to sawing, milling, and shaping.
Additionally, variation in wearer's body and portions of the wearer's body, may require adjustment to the pre-formed stress point locations and a multiplicity of pre-formed stress point locations. Example, a user with more fragile fingers may require a very low predetermined load able to separate a wearable device when compared to a user with relatively less fragile fingers.
