Parallelepipedal Locking Block for Thin Profile Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cylinder lock designs often have thick profiles that are incompatible with certain applications and lack sufficient depth to prevent tool introduction for lock picking, and they restrict users to specific lockers without the option to choose from available ones.
Innovation Solution
A security locking system with a cylindrical design featuring a set of pistons that can be positioned by elastic means on the key's edge, a parallelepipedal locking block, and a receiving block with a guide and control mechanism that allows the key to release the locking block, enabling user selection of lockers and enhanced security through increased depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a traditional cylindrical key lock design is used, then the locking mechanism is simple and reliable, but the lock thickness becomes large which is incompatible with certain applications
Solution Approach 1:
The lock is divided into two separate blocks: a locking block containing the piston mechanism and a receiving block that receives it. This segmentation allows the locking functionality to be achieved with a reduced overall thickness while distributing the mechanical complexity across modular components.
Solution Approach 2:
The invention transitions from a traditional cylindrical rotor design to a parallelepipedal block design, changing the dimensional orientation of the locking mechanism. This allows the lock to achieve its functionality in a thinner profile by reorienting the mechanical elements along different spatial axes.
2Length of moving object
If the admission light depth is reduced, then the lock thickness is reduced, but the ability to prevent tool introduction for lock picking is insufficient
Solution Approach 1:
The locking block is separated from the main lock body into a distinct removable component. This segmentation allows the admission light depth to be reduced while maintaining security, as the locking block can be designed with integrated anti-picking features and replaced as a unit.
Solution Approach 2:
The locking block is pre-positioned within the receiving block and held by maintaining means (such as spring blades) before the key operation. This preliminary positioning creates an additional mechanical barrier that prevents tool introduction, as the locking block must first be disengaged from its seated position before any picking attempt could reach the pistons.
3Adaptability or versatility
If a fixed key-barrel adequacy system is used, then each user is assigned a specific locker, but the user cannot select from available lockers or change according to needs
Solution Approach 1:
The locking block is designed as a universal component that can be inserted into any receiving block (locker) in the system. The standardized interface and profile matching mechanism allow a single locking block to function with multiple different lockers, enabling users to select and change lockers according to their needs without requiring different keys or barrels.
Solution Approach 2:
The system transitions from a static, fixed assignment configuration to a dynamic, selectable configuration. The locking block can be freely inserted into and removed from different receiving blocks, allowing the user-locker assignment to change dynamically based on user needs while maintaining secure locking functionality through the profile matching and maintaining means.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system reduces lock thickness, prevents tool introduction, and allows users to choose from available lockers, enhancing security and usability by enabling the selection of suitable lockers and preventing unauthorized access.
Implementation Method 1
The rotor has a series of pistons, each of which is solicited by a spring that applies them, when a key is inserted into the lock, against the edge of the key
Implementation Method 2
The means for maintaining can consist of a spring blades, one end of which will be fixed on the receiving block and the other end of which will comprise a hook capable of cooperating with a notch of the locking block in order to maintain the latter with the receiving block

AI summary
The present invention relates to a security locking system of the type comprising a cylinder (3) provided with a set of pistons (8) that are able to be positioned by elastic means on the impression formed in the edge (7b, 7c) of a control key (7) perpendicularly to the direction in which said key (7) is introduced into the cylinder (3), these pistons (8) being able to take up two positions, namely a position retracted into the cylinder (3) when the key (7) is introduced into the latter and an extended position when the key (7) is withdrawn there from. This system is characterized in that:—the cylinder is made up of a locking block (3) of parallelepipedal shape that is able to be received in a receiving block (5),—it comprises locking means which are activated when the locking block (3) is introduced into the receiving block (5).
