Nail Extractors TRIZ Cases

A guarded multi-strike tack strip tool protects fingers during floor-level nailing and reaches toe kick recesses while reducing tool changes.

A guided hollow tube and electric linear drive stabilize the claw mechanism for reliable removal of long railroad spikes with easier handling.

A guided hollow tube and direct claw connection improve railroad spike pulling stability, stroke height, and handling for track maintenance.

A rotating removal unit and paper pressing mechanism lift staple crowns stably across paper types while keeping the remover compact.

Spring-biased fingers grip nail heads securely to remove embedded nails with less force, less surface damage, and optional drill or robot use.

A ratcheted lever tool pushes and locks the spring push into the housing, improving optical connector assembly precision and reducing rework.

A nail gun attachment uses an extraction pin to grip the nail point and pull out protruding nails when the head is inaccessible.

Repeated insertion-part reciprocation lowers pullout resistance, enabling complete staple removal from thick, rigid sheet bundles.

An onboard battery, motor control circuit, and pull-rod sensing replace hydraulic hoses while reducing fatigue and speeding railroad spike removal.

Spring-biased fingers grip nail heads through a tube, reducing manual force and helping remove nails without damaging surrounding material.

Vertical motor placement utilizes empty space during operation to reduce device height and width dimensions without adding guiding mechanisms.

A patch deployment device uses a U-shaped connection clip to reversibly attach and detach surgical patches during laparoscopic procedures.

Segmenting the engagement portion with a notch and taper allows controlled force application, preventing fastener damage during extraction.

Circumferential abutment elements distribute extraction force across multiple points, preventing bone breakage during osseointegrated staple removal.

A trigger-operated endoscopic stapler bends prongs to deploy and close staples through a small working channel.

Segmented turns trap the eyelet edge to prevent accidental release during surgical manipulation while allowing axial rotation for easy disassembly.

A hydraulic pumping cylinder adjusts fluid flow using variable piston and rod areas to move large volumes rapidly under low pressure.

A staple removing device uses a tapered guide part to position the fold of a closed booklet against an aligning surface.

Lever arms with interlocking teeth grip short or headless pins without requiring protrusions, resolving cleaning complexity.

A spherical bit with bevel edges grips damaged fasteners for angled torque application.

Convex biasing ridges on a plate create mechanical leverage that lifts planks without splitting them while engaging nails for removal.

Spreading device captures and expands applied surgical clips through a minimally invasive access point.

Pivotable levers adapt to varying pothole depths, resolving the trade-off between tool versatility and structural complexity.

A portable railroad spike remover uses a motor-driven lead screw to vertically lift an extractor for efficient spike removal.

A wedge-shaped demolition tool features a keyhole-like recess for nail extraction between the front edge and handle attachment.

A feeder uses depth-based staple detection to switch take-out modes for accurate paper extraction.

A staple removing device uses a movable paper pressing part to secure bundles during removal.

A connectable tool assembly uses a slidable locking mechanism to attach a secondary pry bar to a hammer handle.

A nail removal tool uses a sliding fulcrum and toothed claw to minimize substrate damage during extraction.

An abutment portion restricts movement during insertion, ensuring reliable staple removal without damaging the paper bundle.

Integrating a switching valve into the workpiece holder eliminates external piping, reducing leakage losses while enabling easy detachment from the base.

Segmented securing sleeves prevent oblique stud positioning and ejection during automated feeding.

An electric nail punching machine replaces hydraulic lines with an electric drive motor and vibration decoupling device, eliminating hand-arm vibrations.

An angled pry tool with an arcuate base reduces operator strain and prevents damage during wood detachment.

Concentric rocking motion between arcuate plates increases grip pressure on the nail shank, resolving versatility and ease-of-operation contradictions.

A pin extraction instrument uses a side slot guide to direct pins into the channel for secure retention.

Motor-driven winch lifts a pivoting claw assembly vertically, replacing manual crowbars that require over 2,265 kg of force.
