Solution Overview
Problem
Existing locking devices for doors, particularly those requiring electric motors and magnets, are complex and costly, lacking a simple and cost-effective solution for both locking and unlocking mechanisms.
Innovation Solution
A locking device featuring a bolt assembly and a bolt receiving device with a magnetic locking mechanism, where the locking element is moved into and out of engagement using magnetic force, allowing for a simple and electrically switchable locking and unlocking process, utilizing an electromagnet and spring-loaded components for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electric motors and magnets are used for locking mechanism, then reliable locking function is achieved, but device complexity and production cost increase
Solution Approach 1:
The patent combines the magnetic device and bolt receptacle into a single integrated component. The magnetic device is embedded within the bolt receptacle structure, eliminating the need for separate mounting brackets and reducing the number of parts. This merging approach maintains reliable locking function while significantly reducing device complexity and production cost.
Solution Approach 2:
The bolt receptacle serves multiple functions: it guides the bolt element during movement, provides the magnetic field for locking, and acts as the receiving structure for the bolt. By making the bolt receptacle multi-functional, the patent reduces the overall number of components needed while maintaining reliable locking operation.
2Reliability
If conventional electric motors are used for bolt movement, then reliable locking and unlocking is achieved, but production cost increases
Solution Approach 1:
The patent replaces the conventional electric motor with a magnetic field-based actuation system. The magnetic device generates electromagnetic force to move the bolt element directly, eliminating the need for mechanical motor components such as gears, shafts, and motors. This substitution maintains reliable locking and unlocking functionality while significantly reducing production cost and simplifying the manufacturing process.
Solution Approach 2:
The magnetic device uses electromagnetic attraction to directly move the bolt element into the locked position without requiring separate actuating mechanisms. The system essentially uses its own magnetic field to perform the work of moving the bolt, eliminating the need for external motors and reducing production cost while maintaining reliability.
