Portable Grinding Machines TRIZ Cases

Adjustable flow cross-sections connect inlet openings to a suction connection, reducing unwanted airflow over non-engaged surfaces.

A powered abrasion device rotates contact surfaces to permanently degrade label legibility and detach labels from containers.

Circumferential arrangement of an indication element on the housing prevents information concealment and improves operator visibility.

A handheld cleaning machine centers its drive motor within the handle to improve operator balance and grip security.

Flow directing portions on the motor rotor generate swirling and axial airflow to discharge thermal heat, resolving overheating in sealed machine tools.

Tilting a spring-biased counter-brake disc releases the drive shaft, solving complexity and cost issues in angle grinder braking systems.

Portable machining system forms angled retention grooves in stamping die cavities without removing the die from the press, eliminating production downtime.

Dual battery attachments combine two 18V packs to deliver 36V power, eliminating the need for expensive proprietary batteries.

A rail grinding machine uses a pivotable motor frame to position the grinding unit for precise profile machining.

Segmented deformation members allow independent angle adjustment, enabling the grinding pad to fit continuous irregular non-horizontal surfaces.

A wear-resistant strip replaces flexible bristles on a drywall sander housing to maintain stable sanding head positioning.

Segmenting clamping and locking functions resolves the trade-off between easy installation and stable angular position for safety compliance.

Segmenting the protective device into a screen unit and light guide unit directs illumination to the workpiece while shielding the operator from blinding light.

Hardened limiting members lock ring gears against axial movement, preventing gear skipping caused by housing deformation during long-term use.

A rail profiling device adjusts a pivotable planing mechanism to shape crossover surfaces matching specific wheel tread geometries.
