Interchangeable Core Lock Barrel Sliding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lock designs with interchangeable core cylinders are inefficient and bulky, lacking in space-saving mechanisms.
Innovation Solution
The design incorporates a housing with a longitudinal axis and slots, a barrel with perpendicular slots, and a prong driver with engaging elements that allow for efficient sliding and rotation to lock and unlock the mechanism, utilizing a retaining piece and prongs to secure the barrel in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional interchangeable core cylinder lock designs are used, then the lock provides basic locking functionality, but the locking mechanism becomes bulky and inefficient
Solution Approach 1:
The locking mechanism is divided into separate functional components: a barrel for holding the core, a prong driver with engaging elements for actuation, and a retaining piece for positioning. This segmentation allows each component to be optimized independently, reducing overall bulk while maintaining efficiency
Solution Approach 2:
The slot is designed with a specific geometric configuration that includes a portion extending perpendicular to the longitudinal axis. This dimensional change allows the engaging element to move between locked and unlocked positions through a compact rotational path, reducing the space required for the locking mechanism
2Ease of operation
If the barrel is made slidable for easy operation, then key operation becomes easier, but the security and stability of the locked position may be compromised
Solution Approach 1:
The retaining piece acts as an intermediary component between the barrel and the housing. It includes a portion that engages with the slot to control barrel movement, providing a reliable locking mechanism while still allowing controlled sliding when the engaging element is actuated
Solution Approach 2:
The slot is designed with an asymmetric configuration where one portion extends perpendicular to the longitudinal axis. This asymmetric design creates a reliable engagement geometry that ensures secure locking while allowing smooth operation when the engaging element moves to the appropriate position

AI summary
A locking device is provided including a housing, a barrel, an interchangeable core (IC), and a prong driver. The housing extending along a longitudinal axis and including a first slot. The barrel slidably disposed in a hollow interior of the housing, where the barrel is slidable along the longitudinal axis. The barrel including a second slot and a hollow interior to retain the IC. The IC including a key hole and coupled to the prong driver. The prong driver including an engaging element extending from the prong driver perpendicularly to the longitudinal axis into the first slot and the second slot. When a proper key is inserted into the key hole and rotated, the engaging element is rotated within the first and second slots to allow the barrel to slide along the longitudinal axis to lock and unlock the locking device.
