MULTILAYER COIL ARRAY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18480932 titled 'MULTILAYER COIL ARRAY

The patent application describes a multilayer coil array with a magnetic layer, first and second coils, outer electrodes, and lead-out conductors.

  • The element body of the coil array contains a magnetic layer.
  • Inside the element body, there is a first coil with conductor layers stacked in a certain direction.
  • A second coil is positioned further from the bottom surface of the element body than the first coil, also with conductor layers stacked in a specific direction.
  • Outer electrodes are located on the bottom surface of the element body, with the first coil connected to the first set and the second coil connected to the second set.
  • A lead-out conductor inside the element body connects the end portion of the first coil closest to the second coil to the first outer electrode.

Potential Applications: - This technology could be used in wireless power transfer systems. - It may find applications in magnetic resonance imaging (MRI) machines. - It could be utilized in electric vehicle charging systems.

Problems Solved: - Improved efficiency in energy transfer. - Enhanced magnetic field control. - Increased reliability in coil array systems.

Benefits: - Higher energy transfer efficiency. - Better control over magnetic fields. - Enhanced reliability and durability.

Commercial Applications: Title: "Enhancing Energy Transfer Efficiency with Multilayer Coil Arrays" This technology could be commercialized for use in wireless charging systems for consumer electronics, medical devices, and electric vehicles. It could also be integrated into industrial power transfer systems for increased efficiency and reliability.

Questions about Multilayer Coil Arrays: 1. How does the positioning of the second coil relative to the first coil impact the performance of the multilayer coil array? 2. What are the potential challenges in manufacturing and integrating this technology into existing systems?


Original Abstract Submitted

A multilayer coil array includes an element body including a magnetic layer; a first coil inside the element body and including first coil conductor layers in a stacking direction; a second coil inside the element body at a position further from a bottom surface of the element body than the first coil in the stacking direction and including second coil conductor layers in the stacking direction; first and second outer electrodes on the bottom surface of the element body and electrically connected to the first coil; third and fourth outer electrodes on the bottom surface of the element body and electrically connected to the second coil; a first lead-out conductor inside the element body and connecting, out of end portions of the first coil, an end portion of the first coil conductor layer closest to the second coil to the first outer electrode.
