Bidirectional Lock with Mirror-Symmetric Subsystems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks cannot distinguish between public and private spaces, limiting their application in shared areas and being unsuitable for both hinged and sliding doors, with issues such as unidirectional operation, vulnerability to external forces, and lack of universal compatibility.
Innovation Solution
A lock system with two mirror-symmetric sub-locking systems, each comprising a cylinder mechanism, mechanical locking mechanism, and motorized locking system, allowing independent operation on both sides for public or private space management, with features like automatic unlocking and jamming to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing locks are designed with locking capabilities on one side only, then the lock structure is simple, but the lock cannot be operated bidirectionally for shared space management
Solution Approach 1:
The lock is divided into two independent sub-locking systems arranged mirror-symmetrically on both sides of the door. Each sub-locking system includes its own cylinder mechanism, mechanical locking mechanism, and motored locking system, allowing independent bidirectional operation while maintaining manageable complexity through modular design
Solution Approach 2:
The lock system is designed to perform multiple functions: it can lock/unlock from either side, support both hinged and sliding doors, provide mechanical and motorized locking options, and accommodate different door configurations through adjustable components, making it a universal solution for various access control needs
2Strength
If existing latches are designed with small width, then the latch mechanism is compact, but the latch is vulnerable to breaking when the door is forced open
Solution Approach 1:
The latchbolt mechanism features a nested structure where the latchbolt is housed within a receiving hole, and the mechanical locking mechanism provides an additional nested layer of protection. The jamming mechanism further nests within the overall structure to prevent abnormal opening, providing enhanced strength without excessive external dimensions
3Reliability
If existing latches are translational mechanisms without jamming, then the latch operation is simple, but abnormal opening may easily occur without a latch jamming mechanism
Solution Approach 1:
The mechanical locking mechanism includes a jamming component that proactively prevents abnormal opening before it can occur. The jamming mechanism is positioned to block the latchbolt's movement path in advance, counteracting potential forced entry attempts or abnormal opening forces before they can compromise security
4Adaptability or versatility
If existing locks are designed for hinged doors only, then the lock design is specialized, but the lock cannot be applied to sliding doors
Solution Approach 1:
The lock system is designed as a universal mechanism that can be installed on both hinged and sliding doors. The mirror-symmetric sub-locking systems and adjustable components allow the same lock design to accommodate different door types and configurations, eliminating the need for separate specialized locks for each door type

AI summary
The present invention discloses a lock that does not distinguish between public and private spaces and relates to the field of locks, comprising two sub locking systems which have the same structure, wherein the two sub locking systems are arranged mirror symmetrically on two sides. It can be optionally installed on both spaces where privacy is needed and a change of the entire lock is not required, such that all designs of an indoor layout and different requirements for design logics regarding doors are adjusted to, that a locking on both sides in an electrically controlled manner is possible, that rotation of a cylinder on both sides is prevented, and that an unlaching movement on both sides in an electrically controlled manner is possible.
