Spanners TRIZ Cases

Separating operation claws from the switch member prevents unintended switching caused by claw oscillation while maintaining torque in a compact handle head.

A threaded magnet insert screws into the driver head to securely hold fasteners.

A quick-turning wrench driving end uses segmented grip surfaces to enable rapid rotation without a pawl mechanism.

A hybrid torque wrench merges torque application and angle measurement into a single unit using electronic controllers for automatic mode transition.

A screwdriver design isolates conductive sleeves with an intermediary insulating layer, eliminating electric shock risk while maintaining tool versatility.

A hex driver bit features contoured tapered engagement channels on alternating flat surfaces to secure rotational torque transfer.

A hex tool with a spherical joint between the head and handle.

Sloping retention units hold offset keys in angular planes, preventing detachment of smaller tools while reducing case volume.

A bit accessory sleeve with a magnetic limiting member holds bits securely for one-handed operation.

A central toolhead wrench inverts traditional handle geometry to enable bidirectional torque application from both arms.

Nested ball bearings maintain concentric alignment of tool shafts, eliminating perceived play and toggle during rigid attachment.

Camshaft-driven hammer converts continuous motor rotation into rotational impacts, delivering 1,700 ft-lbs torque while limiting current draw to 100 Amperes.

Segmented hammer and anvil components deliver striking rotational force while a locking mechanism enables manual torque wrench operation.

A segmented ratchet mechanism distributes load across multiple pawls to resolve the contradiction between high torque strength and device complexity.
