Fastening Means TRIZ Cases

A magnetic coupling auto-aligns the center pin and lower punch, enabling precise robot removal and insertion in powder presses.

A ball plunger and ring member let an ejector pin lock, release at a set force, and simplify compact mold ejection.

A stepped groove and retainer ring enable easy collar assembly, strong force transfer, and permanent shaft retention without shearing.

Snap-fit locking elements and a cover frame simplify sash assembly while concealing joint gaps and maintaining weather-tight sealing.

A sliding carriage between guardrail beam and post uses friction and controlled release to absorb collision energy without losing beam position.

A rotary latch and locking element enable tool-free format part replacement for different container sizes while keeping guidance secure.

A fastening device uses a reciprocation actuator to guide a telescopic screw along its axis.

Axially adjustable locking bolt uses radial retaining means to prevent theft while simplifying handling in tight spaces.

Standardized equilong frame edge members enable reusable backplane modules, eliminating unique molds and shortening development cycles.

Clutch disengages handle from latch bolt when locked, preventing force amplification damage to outer operational device components.

A resilient arm in a rotatable locking member biases adjacent flooring panels into a flush position, preventing dust accumulation in joint gaps.

Segmenting the locking mechanism into independent components resolves manufacturing complexity and force selection trade-offs for reliable axial security.

A flexible ring with locking teeth engages a tank cap to secure a carrier bag, eliminating strap-induced paint scratches.

Self-aligning split collets and anti-friction thrust bearings reduce rotational friction and misalignment during tight-space bearing removal.

A convertible top locking device uses a vertical pivot crank drive to actuate the locking hook.

A planetary gear carrier uses interlocking splines to distribute mechanical loads across the hub and ring assembly.

Segmented supporting rings use bayonet joints to maintain rotational fixity under alternating loads and thermal expansion differences.

A punch-handling tool clamps and aligns workpiece parts before clinching them together without filler materials.

Pivoting flaps with sloping edges prevent stud extraction under shock, resolving assembly complexity and stability trade-offs.

A threaded adjusting member moves a pin through guide slots to eliminate spacing between the draw member and retractor, ensuring full latch bolt retraction.

Segmented head spring with corrugated and rigid zones enables smooth sliding movement, preventing height offset under unequal loading.

A dual-groove connector uses a canted coil spring that rotates between positions to enable secure latching and safe disconnection.

A connecting element for motor vehicle doors uses a nested crossbar design to maintain assembly freedom during preassembly.

Double crossing clip secures parallel fuel and liquid agent tubes via interlocking lugs and grooves, eliminating screwing operations to simplify assembly.

Mechanical interlocks replace hydraulic systems to position vehicle bodies with zero dimensional tolerance.

A rotatable locking member within a flooring groove mates with a panel tongue to eliminate gaps that cause dust accumulation and visual disruption.

A motor vehicle lock uses a blocking lever with two opposite lever arms to improve rotational ease and ensure precise locking.

A deformable intermediate component accommodates manufacturing variances to eliminate gaps and rattling in mated assemblies.

A hollow tube socket uses a kernel collet and guide channel to align a fastening screw for secure wall deformation.

A clamping reinforcement device applies prestress to composite parts.
