Permanent Magnets TRIZ Cases

A four-magnet two-period undulator switches field periodicity by axial displacement, widening spectral range without heavy lifting gear or complex motor control.

An electromagnetic pop-up transparent plate shifts from flush to 45° tilt, enabling vehicle-skin hologram display without package space invasion.

A limited set of permanent magnet types is optimized by orientation and dipole strength to cut stellarator cost while minimizing error fields.

Automated low-field MRI setup adjusts thermal management and field settings to keep portable scans stable across changing environments.

A toroidal magnetic field separates thin metallic sharps radially, reducing tangles and enabling safer, faster single-item retrieval.

A coil switches a rotary magnet between holding and release states, cutting power use and avoiding motor-driven magnetic force control.

A PEEK or epoxy rotor sleeve shields magnets from corrosive process gas while preserving hermetic cooling and machine life.

Magnetic cartridge positioning aligns selected chambers with the aerosol path, enabling flavor switching without replacing cartridges.

Coaxial multipole magnets bias a case lid toward open or closed positions, improving stability without complex mechanical hinge parts.

A rotatable rear magnetic structure separates opposite poles to create switchable single-pole flux with deeper work-piece penetration.

A third magnet layer counteracts mid-stroke magnetic resistance, cutting the force needed to switch permanent magnets ON and OFF.

A magnetic sub-assembly, suction interface, and mechanical support keep in-vehicle electronics stable under vibration while allowing easy release.

Different wall thicknesses and diameters let a tubular magnet holder tune press-fit load, resist buckling, and preserve the magnetic circuit.

Grooves and same-material connecting portions block eddy current paths while avoiding segmented bonding, cutting loss, scrap, and cost.

Two magnetic field sensors on a shared substrate boost signal strength and reject interference for precise rotation and tilt sensing across larger air gaps.

Holding magnets and adhesive bond like-pole magnets in contact without heat or impact, preserving magnetic power and preventing damage.

Distributed magnets and shielding keep a wallet attached to a phone while limiting magnetic interference with circuitry and onboard magnets.

Solenoid inductance measurement replaces short-life mechanical switches to detect elevator safety brake actuator position with lower noise and cost.

A two-section opposite-wound coil on a tubular holder cuts actuator assembly cost and complexity while preserving stability and accuracy.

Rotating permanent magnets and integrated sensors vary magnetic flux for reliable coupling to ferromagnetic workpieces across multiple contact surfaces.
