Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cylinder locks lack sufficient security against tampering and require complex production processes, leading to increased costs and reduced efficiency.
Innovation Solution
A rotor design for cylinder locks featuring a main body with a seat for key insertion, movable locking elements, and rotating elements with grooves that allow for multiple bitting configurations, along with additional security members, which can be easily produced using aligned machining processes to enhance security and reduce production time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cylinder lock designs are used, then the structure is simple to manufacture, but the security level against tampering is insufficient
Solution Approach 1:
The rotor is segmented into multiple functional components: a main body, multiple rotating elements (pins), and a locking element. Each component performs a specific function, allowing the system to achieve high security through the coordinated interaction of simple, manufacturable parts rather than requiring a single complex structure.
Solution Approach 2:
The rotating elements and locking element are nested within cavities in the rotor body. The locking element moves between cavities to engage or disengage from the stator, while rotating elements rotate within their own cavities. This nesting allows multiple security functions to be integrated within a compact, manufacturable rotor structure.
2Reliability
If multiple security members are added to increase security, then the security level improves, but the production process becomes more complex and time-consuming
Solution Approach 1:
Multiple security functions are merged into a single rotor component. The rotor integrates the main body, multiple rotating elements, and a locking element that moves between cavities, all of which work together to provide multiple security layers. This consolidation allows the security functions to be manufactured as one integrated piece rather than assembling multiple separate components, maintaining production efficiency.
3Reliability
If the rotor design includes multiple rotating elements and locking mechanisms, then security against lockpicking and bumping increases, but the manufacturing complexity and cost increase
Solution Approach 1:
The rotor features localized functional zones: cavities are positioned at specific locations to house rotating elements and the locking element. Each cavity and component has a specific function tailored to its location, allowing standard manufacturing processes to be applied to each zone independently while achieving high overall security through the strategic arrangement of these localized features.

AI summary
A rotor (1) for a cylinder lock (100), comprising: a main body (2) extending along a longitudinal direction (P); a seat (3) adapted to house a key; a locking element (7) movable between a locked configuration and a disengaged configuration; a plurality of rotating elements (8) arranged inside the main body (2) and in sequence with each other along said longitudinal direction (P). Each of the rotating elements (8) is able to rotate about its own axis of rotation (51) perpendicular to the longitudinal direction (P) during the insertion of the key inside the seat (3). Furthermore, each of the rotating elements (8) has a groove (13) to receive at least a portion of the locking element (7) to allow the latter to assume the disengaged configuration. The locking element (7) is movable between the locked condition and the disengaged condition along a work direction (52) parallel to the axis of rotation (51). A further object of the present invention application is a method for realising said rotor (1).
