Permanent Magnets TRIZ Cases
- Bistable Permanent Magnet Coil Circuit for Reversible PWM Current
A five-switch coil circuit reverses current without load breaking, simplifying bistable permanent magnet control while enabling PWM.
- Magnetic Accessory Positioning for Adjustable Angles and Thermal Control
Multi-pole magnets and flux sensing enable stable viewing angles while limiting over-folding and improving thermal operation of covered electronics.
- Magnetic Wheel Cancellation Loop for Switchable Surface Adhesion
A serpentine isolator ring and rotating annular discs vary magnetic flux, giving magnetic wheels strong grip and easier release on ferromagnetic surfaces.
- Magnetic Assembly Layout for Bi-Axial Pigment Orientation
Segmented bar dipole magnets create direction-changing fields that bi-axially orient pigment platelets over large coating areas for high-speed printing.
- 3D Multipolar Magnet Array for Foldable Display EMR Compatibility
A 3D multipolar magnet array redirects magnetic flux to close the foldable housing gap while reducing EMR stylus interference on the display.
- Three-Pole Magnetic Field Layout for Better Field Utilization
A three-pole magnetic layout exposes field transition interfaces to improve magnetic field use, suspension, and object acceleration.
- Magnetic Phone Holder Structure for Detachable Stable Attachment
Opposed magnet layers create a detachable phone holder that stays stable in use while preserving device appearance when removed.
