Definitions

  • thermoelectric and photovoltaic devices are configured to passively capture energy from heat, light, etc. While these devices are adequate for charging a wristwatch (not a smartwatch), these devices are not adequate or efficient enough to capture sufficient energy to charge a portable electronic device.
  • Some manufacturers have attempted to improve energy harvesting by increasing the size of the energy harvesting actuator/transducer. However, the increased size reduces the portability and comfort of using/wearing these energy harvesting devices.
  • the example kinetic energy harvesting device is operable in two states: an energy harvesting state 100 and a portable electronic device charging state 200.
  • FIG. 1 shows a diagram of a kinetic energy harvesting device 102 in the energy harvesting state 100, according to an example embodiment of the present disclosure.
  • a user 104 wears or otherwise possesses the kinetic energy harvesting device 102 while performing an activity.
  • the activities may include running, walking, climbing, swimming, bicycling, sitting, sleeping, standing, bouncing in a chair, socializing, riding, playing a sport, having sex, etc.
  • the dimensions of the central magnet 408 may change based on application, technology, etc.
  • the central magnet 408 may have a height, width, and/or thickness with nano-dimensions or micro-dimensions.
  • the central magnet 408 may have a height, width, or thickness that ranges from a few centimeters or inches to hundreds of inches.
  • FIG. 19 shows a diagram where an array of relatively small central magnets is used within a device housing and/or one or more magnet housings, according to example embodiments of the present disclosure.
  • the kinetic energy harvesting device 102 may accommodate an array of the magnet housings 304 to increase an amount of kinetic energy captured.
  • the central magnets may be positioned and/or spaced to facilitate magnetic coupling so that they move at the same speed in the same direction.
  • the array of magnet housings may charge one or more batteries. For example a top portion of the array may charge a first battery and a bottom portion of the array may charge a second battery that is electrically parallel to the first battery.
  • the ferrous shield 2102b is placed on a side of the magnet housing 304b this is opposite of a side 2103b facing the other magnet housing 304a.
  • the ferrous shields 2102a and 2102b are configured to create attractive forces F 2 with respective central magnets 304a and 304b.
  • Dimensions and properties of the ferrous shields 2102a and 2102b are selected so that a magnitude of the attractive force F 2 is substantially equal to the attractive force Fi between the central magnets 408a and 408b (e.g., selected so there is no net attractive force in the horizontal or lateral direction).
  • FIG. 29 shows a diagram of a kinetic energy harvesting device 102 that includes a two-dimensional array of magnet housings 304, according to an example embodiment of the present disclosure.
  • the ferrous shields 2102 are placed in locations to balance the inter-magnet attractive forces Fi and F 2 .
  • Fi is an inter-magnet attractive force between nearest neighbor central magnets 408
  • F 2 is an inter- magnet attractive force between next nearest neighbor central magnets 408.
  • the mass and properties of the ferrous shields 2102 are determined based on the configuration of the array and the strength of the central magnets.
  • the forces on each central magnet may be geometrically resolved to help determine the mass and properties of the ferrous shields to accordingly resolve force imbalances.

Abstract

La présente invention concerne un système, un procédé et un appareil destinés à la récupération d'énergie cinétique. Un appareil de récupération d'énergie cinétique donné à titre d'exemple comprend un logement d'aimant de forme tubulaire, un premier aimant de bouchon d'extrémité conçu pour se connecter à une première extrémité du logement d'aimant et un second aimant de bouchon d'extrémité conçu pour se connecter à une seconde extrémité du logement d'aimant. L'appareil comprend également une première bobine de fil conçue pour être connectée au logement d'aimant entre la première extrémité et un centre du logement d'aimant et une seconde bobine de fil conçue pour être connectée au logement d'aimant entre la seconde extrémité et le centre du logement d'aimant. L'appareil comprend en outre un aimant central conçu pour être situé à l'intérieur du logement d'aimant entre la première extrémité et la seconde extrémité de sorte que l'aimant central est suspendu à l'intérieur du logement d'aimant.
