Boltless Mortise Lock with Integrated Electronic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mortise locks require significant economic and installation efforts for burglary security, especially when retrofitting or replacing locks due to lost or stolen access cards, and lack flexibility in electronic locking mechanisms.
Innovation Solution
A boltless mortise lock design that uses a latch for locking, with electronic components integrated inside the lock case, eliminating the need for external authorization verification and power supply installations, allowing for easy retrofitting and minimizing installation effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional mortise lock with bolt and key-operated profile cylinder is used, then burglary security requirements are met, but economic effort and installation complexity increase significantly when retrofitting or replacing locks
Solution Approach 1:
The patent extracts the bolt mechanism from the locking system, creating a boltless mortise lock that uses only a latch for securing the door. This simplification reduces the number of components that need to be installed and retrofitted, thereby reducing installation complexity while maintaining adequate burglary security for interior doors
Solution Approach 2:
The patent integrates electronic authorization verification and power supply functions within the lock case itself, making the lock case a multi-functional unit that combines mechanical locking with electronic access control. This integration eliminates the need for separate external installations, reducing overall system complexity
2Reliability
If conventional locks are replaced to restore security after chip card loss, then burglary security is restored, but economic cost increases due to replacing multiple locks or entire locking systems
Solution Approach 1:
The patent implements dynamic electronic authorization verification that can be reprogrammed without hardware replacement. When chip cards are lost or stolen, the electronic authorization data stored in the lock case can be updated or reconfigured, allowing security restoration without replacing the entire locking system, thereby reducing economic effort
Solution Approach 2:
The patent allows for the recovery and reuse of the existing lock case hardware while only replacing or reprogramming the electronic authorization components. This selective replacement approach discards the need to replace mechanical components, recovering the value of the existing lock case and reducing overall replacement costs
3Adaptability or versatility
If electronic locks are integrated inside the lock case, then flexibility and retrofitting ease improve, but space availability in the lock case becomes constrained
Solution Approach 1:
The patent segments the nut into two separate halves (inner and outer), creating modular components that can be independently positioned and configured. This segmentation allows for optimized spatial arrangement of electronic components within the lock case, providing flexibility in component placement while managing space constraints
Solution Approach 2:
The patent nests the electronic authorization verification means and power supply within the existing lock case volume, utilizing the internal space efficiently. The electronic components are integrated into the available cavities and spaces within the lock case structure, allowing flexible functionality without requiring additional external mounting space

AI summary
A two-part locking nut has inner halves (20a) with an active link to a latch (14) and outer halves (22a) linked to the inner halves by a change-over element (30) controlled via electromechanical means (34) between coupling and releasing positions. The change-over element can be affected by electronic devices designed to check on authorization.
