Cylindrical lock single key rotation mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cylindrical locks lack a mechanism to efficiently control unlocking and locking operations using a single key rotation, requiring separate handle operations for locking and unlocking, which complicates the locking mechanism and user experience.
Innovation Solution
A cylindrical lock design featuring a transmission structure with a tubular shaped element, collar, engaging element, and rotating part, allowing the lock core to rotate from an angled position to the beginning position to control unlocking or locking by axial displacement of the engaging element, enabling both locking and unlocking operations with a single key rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional cylindrical lock structure with separate handling of locking and unlocking operations is used, then the lock can perform basic locking and unlocking functions, but it requires separate key operations for different handle sets and lacks a unified method to manage locking and unlocking states
Solution Approach 1:
The patent merges the locking and unlocking operations into a single unified key rotation mechanism. The lock core integrates both locking and unlocking transmission paths, allowing one key operation to control both handle sets. This eliminates the need for separate key operations for different handle sets, directly addressing the ease of operation improvement while managing device complexity through integrated design.
Solution Approach 2:
The lock core is designed with multi-functionality to handle both locking and unlocking operations through a single key rotation. The transmission structure includes universal components that can redirect the key operation to different handle sets based on the operational state, enabling one key to perform multiple functions (locking and unlocking different handle sets) without requiring separate mechanisms.
2Adaptability or versatility
If the lock core rotates from an angled position to the beginning position to control unlocking, then unified key operation is achieved, but the transmission mechanism requires multiple meshing sections and engaging elements
Solution Approach 1:
The transmission mechanism employs dynamic meshing sections that can engage and disengage based on the lock core's rotational position. The engaging elements are designed to dynamically switch between different meshing sections as the lock core rotates from the angled position to the beginning position, enabling adaptable control of locking and unlocking states. This dynamic behavior allows a single key rotation to control multiple operations without requiring permanently engaged complex mechanisms for each state.

AI summary
A kind of cylindrical lock, this lock able to be installed on a door, includes: one transmission structure which can operate a drive base, this drive base gearing a latch mechanism; this latch mechanism having: one tubular shaped element, which can be coupled to a handle for actuation; a tube, which can be rotated and inserted into the tubular shaped element; one pushing part, having one side with at least one pushing section, this pushing section able to push the drive base at the appropriate time; a collar, which can be set on one end of the tubular shaped element, a meshing section formed on one end of the collar; an engaging element, partly installed in this pushing part, one meshing section formed on this engaging element, and this engaging element having at least one pushable section; one rotating part, having at least one pushing portion, each pushing portion at the appropriate time pushing the adjacent pushable section of the engaging element; one lock set, having a lock core linked to one transmission part; rotating this lock core to move from the beginning position at an angled position in a predetermined direction back to the beginning position, the transmission part of this lock set can push a moving part, causing this engaging element to do axial displacement, and causing the meshing section of the engaging element to be positioned and move between the incompatible meshing of the first position or compatible meshing of the second position, on the meshing section of this collar.
