Nailing Tools TRIZ Cases

Air-path structure uses sliding safety bar to control pneumatic chambers and shift actuation modes in nail guns.

Replacing solenoid valves with piezoelectric injectors eliminates all-or-nothing dosing, reducing fuel waste in nailing machines.

A combustion-driven setting tool uses a pre-chamber valve to vary maximum charging pressure for precise firing energy delivery.

Motor-driven adjustment of the combustion chamber volume and precise fuel metering reduces operational load and extends service life.

A pneumatic cylinder compresses air into a storage chamber, eliminating explosion hazards from pre-stored gas during transport.

A pneumatic safety actuator displaces between locked and open positions using a pressure-dependent counterforce.

Linearly movable pressing roller prevents obstruction during return, reducing machine size and complexity.

An air chamber within the nail gun stores energy to drive hard objects without external compressors.

Camming elements lock the stop against shock forces, eliminating tool requirements and loosening issues.

A dustproof nail gun magazine uses scraper sets on the nail-pressing member to clean scroll spring surfaces during operation.

A shield subassembly with a ramp retracts lifter pins, preventing misalignment jams and ensuring smooth lift strokes.

A cam interlocked with a lift wheel maintains an energizing switch in an on-state to activate the electric motor.

A nail gun safety mechanism uses a cam member and contact member to control firing.

A fastener setting device uses a linear actuating member to transition a bolt between positions.

A spring-biased lockout lever blocks the workpiece contact element when the magazine empties, stopping tool actuation.
