Lock Set Electronic Switches for Door Status Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lock sets do not effectively inform users whether a door is closed, locked, or if the lock is damaged, leading to potential unauthorized access due to undetected damage or misjudgment.
Innovation Solution
A lock set system comprising a driving member, a latch, first and second electronic switches, and a reception unit that transmit signals indicating the door's and latch's states, allowing the reception unit to determine if the latch is broken or the door is open, thereby enhancing security and warning functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lock set is used without sensing switches, then the device complexity is low, but the reliability of detecting door and latch status is insufficient
Solution Approach 1:
The patent replaces mechanical status detection with electronic sensing switches. The first electronic switch detects driving member position (door open/closed status) and the second electronic switch detects latch position (locked/unlocked status), converting mechanical states into electrical signals for reliable detection and transmission to the reception unit.
Solution Approach 2:
The patent introduces electronic switches as intermediary sensing elements between the mechanical components (driving member, latch) and the reception unit. These switches act as mediators that convert mechanical positions into detectable electrical signals, enabling indirect but reliable status detection without direct mechanical connection to the reception unit.
2Loss of information
If no signal transmission system is added, then the device complexity remains low, but the loss of information about door and latch status occurs
Solution Approach 1:
The patent establishes a feedback system where electronic switches continuously monitor the positions of the driving member and latch, transmit status signals to the reception unit, and enable real-time information feedback about door and lock status. This feedback loop prevents information loss by continuously reporting system state to the user or monitoring device.
Solution Approach 2:
The patent replaces passive mechanical status indication with active electronic signal transmission. Electrical signals generated by the electronic switches carry information about door and latch status to the reception unit, ensuring information is transmitted electronically rather than relying on mechanical indication alone.
3Object-affected harmful factors
If electronic switches and signal transmission are added, then the burglarproof function is improved, but the device complexity increases
Solution Approach 1:
The patent uses feedback from electronic switches to detect abnormal status changes that may indicate break-in attempts. When the latch or driving member moves to an unexpected position, the system receives status signals and can trigger warnings or alerts, enhancing burglarproof functionality through continuous monitoring and real-time feedback about system state.
Solution Approach 2:
The patent replaces purely mechanical lock protection with an electronic monitoring system. Electrical signals from the electronic switches provide detectable information about latch and door status, enabling electronic detection of forced entry attempts and enhancing security through signal-based monitoring rather than relying solely on mechanical resistance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system accurately informs users of the door's and latch's states, preventing misjudgment and improving burglarproof functionality by detecting latch damage and ensuring the door's secure closed and locked status.
Implementation Method 1
a first electronic switch is used for sensing whether the driving member operates or not and transmitting a first signal or a second signal
Implementation Method 2
a second electronic switch is used for sensing whether the latch operates or not and transmitting a third signal or a fourth signal
Data Source
AI summary
A method for inspecting a lock set is to utilize a reception unit for receiving the signals from a lock set mounted at a door to inspect whether the door is closed and whether the lock set is locked or being broken.
