Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tubular-type deadbolt door locks lack a mechanism to sense door status, requiring separate sensors and leading to inconvenient automatic locking mechanisms and security vulnerabilities.
Innovation Solution
A tubular-type deadbolt door lock with an edge bolt that includes a deadbolt guide case, a tubular deadbolt case, an edge bolt with spring-wound rods, and a sensor to detect door closure, allowing immediate operation of the deadbolt via a power module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate sensor is installed to sense door status, then door status detection capability is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent merges the door status sensing function with the existing deadbolt mechanism by integrating the edge bolt into the deadbolt assembly. The edge bolt serves dual purposes: it is both part of the locking mechanism and the sensing element that detects door status, eliminating the need for a separate sensor and reducing overall device complexity while maintaining detection capability
2Extent of automation
If automatic locking function is implemented with timer, then automation level is improved, but security vulnerability increases due to delayed locking
Solution Approach 1:
The patent implements a feedback mechanism where the edge bolt's position (which reflects door status) is detected by a sensor and immediately fed back to the control unit. This real-time feedback allows the system to automatically trigger deadbolt locking when the door is closed, eliminating security vulnerabilities associated with delayed timer-based locking while maintaining automation
3Device complexity
If manual key locking mechanism is used, then device complexity is reduced, but ease of operation deteriorates when user loses key
Solution Approach 1:
The patent replaces the purely mechanical key-based locking system with an electromechanical system that includes a motor-driven deadbolt and electronic control. This substitution maintains simplicity in the mechanical locking action while adding electronic controls that enable remote operation, keyless access, and automated locking, thereby improving ease of operation without significantly increasing overall complexity
