Permanent Magnets TRIZ Cases

A low-alloy soft-magnetic steel bar uses controlled Sn, ferrite ratio, and low hardness to balance corrosion resistance, magnetic properties, and cold forgeability.

A rotatable magnet and ferromagnetic core vary flux from off to partial and full on, matching magnetic holding force to different ferromagnetic workpieces.

A magnetically attached annular holder secures a cigar in multiple orientations while avoiding clip damage, slipping, scratching, and tearing.

An openable ring with adjustable magnet units fits different pipe diameters without remaking magnets, enabling flexible pipe magnetization.

A magnet-driven pin locks into a hinge groove during abnormal folding to stop unsafe rotation and protect the flexible display.

A silicone nanomagnet composite converts biomechanical pressure into stable electrical output with low impedance, even on wet skin or in body fluids.

Multiple asymmetric magnet rings generate a strong uniform axial field with lower weight and reduced fringe fields for portable MRI use.

An electromagnetic rocker arm latch replaces hydraulic latching to cut oil demand, simplify VVL/CDA valvetrains, and ease module installation.

Half-wave rectification and a back-EMF circulating path cut magnetizing pulses while preserving alnico flux in magnetic clamping.

Alternating magnetic poles create secure device alignment and attachment while limiting interference with cameras, compasses, and inductive charging.

Interlocking magnetic tool holders create custom storage layouts that reduce clutter, keep tools visible, and simplify retrieval.

A non-magnetic encapsulating body protects elevator actuator magnet assemblies from stress and fatigue, improving reliability over thousands of actuations.

A magnetic flux pipe redirects actuator fields to Hall sensors, enabling retrofit load control without rewiring or switch replacement.

A stationary solenoid actuates a rocker arm magnetic latch across an air gap, cutting oil demand and avoiding wire fatigue.

Alternating iron core rows and back-surface permanent magnets boost magnetic flux while simplifying motor structure and support.

Bonding the permanent magnet to the housing base and fastening the pole plate separately keeps gap width stable under shocks and vibration.

Cavity-filled magnetic powder agglomerated by atomic layer deposition enables precise substrate-level magnet alignment and compact electronic assemblies.

Patterned coercivity diffusion forms reconfigurable multipole hard micro-magnet arrays without direct surface access after packaging.

Ferromagnetic pins in magnet cavities join Halbach array magnets without adhesives, cutting assembly complexity and adhesive failure risk.

Magnetic alignment guides bracket rotation and terminal movement to reduce contact impact and improve cover-device assembly feel.

Metal-injection-molded NdFeB magnets use nonparallel easy axes to deliver stronger fields in less space while reducing parts, adhesives, and waste.
