Patent number: 11864631Abstract: A force dissipating device in a footwear appliance includes an actuator responsive to a displacement force from a shoe sole surface, and an elastic field of resilient, compressible material. The elastic field is elongated in a direction aligned with the displacement force, and an inclined surface is attached to the actuator and disposed against the elastic field. The actuator is adapted for movement parallel to the elastic field, while the inclined surface is oriented to compress the elastic field in a direction defined by the inclined surface. The inclined surface is oriented at an angle to compress the elastic field in a direction substantially perpendicular to vertical actuator displacement, thus providing a constant region of opposed, compressive force that is generally constant, rather than increasing with displacement distance.Type: GrantFiled: September 12, 2019Date of Patent: January 9, 2024Assignee: Worcester Polytechnic InstituteInventors: Christopher A. Brown, James J. Muller, Julia A. Dunn, Alexander R. Alvarez, Kyle R. Mudge, Rachael Naoum

Patent number: 11622596Abstract: A force absorbing device for a footwear appliance includes a shoe upper and a shoe sole having a planar sole surface, such that forces between the shoe upper and planar sole surface in ground contact are absorbed by force mitigation assemblies disposed in the shoe sole. A force mitigation assembly adapted for an athletic shoe includes a linkage to a wearer interface responsive to movement based on activity of the wearer. An attachment to a sole surface receives ground forces transmitted from frictional contact between the sole surface and a surface against which the sole is disposed, such as for running, turning, etc. A force mitigation assembly absorbs these forces received from the sole surface for directing the received force in a controlled manner. An elastic field in the force mitigation assembly is defined by a resilient material adapted to deform in response to the received force.Type: GrantFiled: October 4, 2019Date of Patent: April 11, 2023Assignee: Worcester Polytechnic InstituteInventors: Christopher A.

Patent number: 11445784Abstract: A force absorbing device for a footwear appliance includes a shoe upper and a shoe sole having a planar sole surface, such that forces between the shoe upper and planar sole surface in ground contact are absorbed by force mitigation structures disposed in the shoe sole. A footwear article includes a split-sole system that redefines a shoe sole as coplanar surfaces having a force mitigating interface for receiving sudden forces and effectively mitigating these forces by storing kinetic energy and releasing it over time. An elastic field in the force mitigation structure is defined by a resilient material adapted to deform in response to the received force. Frictional engagement between the upper and lower sole may also be augmented by surface characteristics such as dimples, voids and lubricants, in addition to interference engagement with an elastic field.Type: GrantFiled: October 4, 2019Date of Patent: September 20, 2022Assignee: Worcester Polytechnic InstituteInventors: Christopher A. Brown, James J. Muller, Winton Parker, Allysa Grant, Tristin J. Carlton, Nicholas Workman, Michael Doyle, Jessica Shelsky, Jessica K. Y. Cheu, Lorenzo Dube, Pedro D. Oporto, Olivia G.

Publication number: 20210127783Abstract: A protective headgear device, or helmet, protects against head injuries such as concussions and CTE by imposing a network of constant force members (CFMs) between an outer impact shell and an inner fitted capsule engaging the skull/head surface. CFMs exhibit a force absorbing behavior that differs from conventional linear spring behavior that impose a counterforce proportional to the displaced distance. CFMs occupy a compact void between the outer impact shell and the inner fitted capsule by component miniaturization and tethers that redirect forces within the void. An absence of conventional foam and straps increases accommodation for the CFMs and connection tethers/attachments. The CFMs exhibit a substantially constant force that avoids a sharp impactful response associated with head injuries.Type: ApplicationFiled: November 11, 2020Publication date: May 6, 2021Inventors: Christopher A.

Patent number: 10888138Abstract: An impact absorbing footwear device employs opposed planar sole portions engaged by a selective resistance coupling that biases the opposed planar sole portions in a non-linear manner in response to forces exerted by the wearer against the sole portion in frictional contact with a floor surface. The planar sole portions are disposed in a footwear appliance that takes the form of an athletic shoe sole. The selective resistance coupling includes a plurality of resilient deformation members that engage the planar sole portions in an opposed circumferentially aligned manner, selectively deform in response to pressure exerted by the wearer for preventing ACL and other impact related injuries, and recover to an undeformed rest position without breakaway to allow the wearer uninterrupted usage while dampening forces that surpass an injury threshold from the resilient deformation that allows the planar sole portions to temporarily misalign.Type: GrantFiled: August 14, 2017Date of Patent: January 12, 2021Assignee: Worcester Polytechnic InstituteInventors: Christopher A. Brown, Nicholas Workman, Michael Doyle, Jessica Shelsky, Jessica K. Y. Cheu, Lorenzo M. Dube, James J. Muller, Pedro D. Oporto, Olivia G. Steen, Andrew R. Vickery
