Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for determining the bolt position in self-locking locks are complex to install and require external sensors, making them difficult to integrate into existing locking devices without extensive wiring and installation work.
Innovation Solution
A device that can be retrofitted into mortise locks, featuring a button element modeled on a lock cylinder, which engages with the bolt mechanism to detect its position using a sensor, allowing for easy assembly and disassembly without the need for external sensors or extensive wiring, and can be used in place of a lock cylinder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external sensors are used to detect bolt position, then detection reliability is improved, but device complexity and installation complexity increase
Solution Approach 1:
The patent combines the bolt position detection function with existing components in the locking system. The detection device is integrated into the locking mechanism itself, merging the detection function with the structural elements already present in the lock, thereby avoiding the need for separate external sensors and reducing installation complexity while maintaining detection reliability
Solution Approach 2:
The invention creates a detection device that can be universally applied to different locking systems by using standardized components and integration methods. The device is designed to work with existing locking mechanisms through multi-functional integration, allowing it to detect bolt position without requiring system-specific external sensors, thus reducing both device complexity and installation effort
2Measurement precision
If external sensors are installed in existing locks, then bolt position detection is achieved, but installation work and wiring requirements increase
Solution Approach 1:
The detection device is divided into modular segments that can be independently installed and configured within the existing locking system. This segmentation allows for precise bolt position detection through distributed sensing elements while simplifying installation by enabling step-by-step integration without requiring extensive wiring or modification of the existing lock structure
Solution Approach 2:
The patent introduces an intermediary detection mechanism that bridges the bolt mechanism and the detection system. This intermediary component translates bolt position into detectable signals without requiring direct connection to external sensors, thereby achieving accurate measurement while minimizing installation complexity and wiring requirements
3Adaptability or versatility
If a retrofit solution is implemented, then adaptability to existing locks is improved, but integration complexity may increase
Solution Approach 1:
The retrofit detection device is designed with universal compatibility features that allow it to be adapted to various existing locking systems. By incorporating multi-functional capabilities and standardized interfaces, the device achieves broad adaptability while maintaining simple integration through its ability to work with different lock mechanisms without requiring complex system-specific modifications
