Keys TRIZ Cases

Segmenting the locking system into an external combination lock and an internal shackle padlock resolves the security vulnerability of single-lock theft.

Radial side locking tumblers engage a fixed sleeve portion, resolving space conflicts for high-security mechanisms in compact lock cores.

Segmented latch members engage ledges to resist separation, resolving the trade-off between security and operational complexity in bait stations.

Segmented helical keyways avoid central through holes, boosting core strength and complicating lock picking by requiring precise key geometry.

Cold-formed torsion sections on key shanks provide complex spatial coding that increases security against manipulation while maintaining manufacturability.

Segmented rotation limiter eliminates non-rotatable parts to reduce device complexity and improve manufacturing ease while maintaining functional reliability.

Segmenting the rotor into rotating elements and nesting them within cavities increases security against tampering while maintaining manufacturing efficiency.

Longitudinally guided punching tools form profile grooves in key blanks while holding surfaces clamp the material to prevent deformation.

A key tip with a flat orthogonal end face maintains consistent surface contact with the coupling element.

Parabolic variation ribs reduce flank steepness to prevent bending during key insertion while maintaining high coding density.

Key blank with transverse notches forms drive slopes for disc cylinder tumblers while preventing sharp edges that cause discomfort.
