Spanners TRIZ Cases

Pneumatic bladder tubes spread holding force evenly inside barrel-shaped parts, preventing distortion during machining.

Pivot-linked rollers move together with the reversing knob to maintain latching, simplify manufacturing, and preserve wrench torque.

Tapered prongs and stepped neck sections stabilize p-clamps during tightening, reducing installer strain and unintended fastener rotation.

Cold-worked compressive stress layers on ratchet cavity and gear surfaces cut wear and fatigue without larger tool designs or costly metallurgy.

A threaded stud and coupler with a reversible ratchet retract brake pistons in narrow caliper gaps while reducing manual effort.

Adding metal to the fan wheel raises rotary inertia, improving spindle lock response, reducing wear, and still cooling the motor.

A detent recess brakes and positively locks the screw head, preventing tip damage and backward movement under high robotic acceleration.

Noise-filtered torque data from repeated tightenings reveals screwdriver wear and screwdriving deviations without stopping production.

An electrical actuator unlocks the torque tool at target torque, decoupling the adapter to prevent over-tightening and thread damage.

An axially movable magnetic assembly and dual sleeves let one extension rod grip and rotate different fastener sizes without rod changes.

Thin side plates with a noncircular aperture let a hydraulic torque wrench fit tight spaces while reducing wear and shielding operators.

A dual-sleeve bit holder secures different shank sizes for fast changes while avoiding the weight, size, and cost of variable chucks.

Controlling rotor speed until gear play closes creates defined torque pulses with consistent energy transfer and lower operator reaction force.

A co-rotating suction nozzle and internal vacuum passages let a power screwdriver pick up screws in tight spaces without wobble.

A cap adapter and torque multiplier engage valve cap holes to remove seized caps safely, making valve inspection and service easier.

A gear-driven adapter turns fasteners less than 2 mm from a wall, enabling larger rotation per cycle and faster attachment or removal.

Multiple radial clamping planes secure and center long stepped-bore workpieces without distortion across varying inner diameters.

Magnetic guide portions and a plate-expanding ejector simplify brake cylinder removal, reducing effort, slipping, and disassembly time.

A grooved nut and three-section socket torque a portable cylinder regulator without hitting valves or disturbing the case-body torque setting.

An elastomer-lined metal guide sleeve improves component alignment during pressing while reducing the cost and complexity of spring steel guides.

Locking balls grip the retention knob flange to apply high torque without rounding flats, reducing slip, damage, and injury risk.

Real-time torque-angle curve analysis stops tightening when preload is reached, avoiding model setup errors and overtightening.

Locator position detection lets the controller stop spindle rotation at the right depth, improving screw driving precision while reducing noise and power use.

A trigger clamp and return spring speed pocket-hole setup, cut user effort, and automatically reset the drill guide for varied workpiece thicknesses.

A slim nozzle and bit-sleeve vacuum path improve access in cramped screw locations while preventing screw wobble during tightening.

A spring-biased outer sleeve and ball detents keep bits locked during use while allowing fast tool-free release and interchange.

A movable stopper replaces spring bias to simplify tool holder operation, ensure driver-camshaft separation, and improve waterproof sealing.

Rotating clamps and a gear-driven adapter grip different fastener sizes without socket changes, cutting tool count and changeover time.

Pre-arranged fasteners are transferred in one pattern-matched step, cutting installation time, placement errors, and loss in tight assemblies.

Noncircular side-plate apertures let a hydraulic torque wrench fit closely spaced flanges while reducing plate wear and pinch risk.

An elastic sleeve clamps small cutting heads on the key, enabling faster secure attachment and release from the tool holder.

A spring-biased outer sleeve and detent layout enable tool-free bit changes while keeping rotary tool bits securely locked.

Laser cutting and 3D machining of flat steel stock reduce wrench tooling cost while enabling complex jaw and handle geometries.

A ball detent and dual-sleeve mechanism locks power tool accessories axially and rotationally, reducing slippage and easing release.

A spring-biased, motor-actuated latch keeps subsea torque tools engaged under load yet releases safely during power loss.

Barcode-identified bolt tensioning records force, pressure, and hand torque to prevent over- or under-tightening of heavy screw joints.

Composite averaging and slope detection track output shaft load to cut shutdown misjudgment in automatic fastening under varying conditions.

Sensors identify visually similar fasteners by material so the tool applies the right torque and speed and prevents assembly errors.

Reaction torque measured at the motor frame enables precise rail screw torque limiting without complex spindle sensors or wear-prone clutches.

A spring-loaded retraction system keeps removable tool pieces tethered yet pulled back to storage, reducing work area obstruction and entanglement.

A stepped rotatable sleeve with visible size markings improves grip, selection, and release operation in quick-release hand tools.
