Elevator Control Panel Wireless Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Control panels in machine-roomless elevators are vulnerable to vandalism due to inadequate locking mechanisms, and existing solutions are not sufficiently effective in preventing unauthorized access or protecting against tampering with the lock itself.
Innovation Solution
An elevator control panel with a wireless, electrically controllable lock mechanism that eliminates the need for a conventional keyhole, incorporating a spindle motor actuator and a manually-operated latch for backup access, ensuring secure operation even during power outages, and a position-coded key for secure wireless signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional keyhole locking mechanism is used in the control panel, then the panel can be locked to prevent unauthorized access, but the keyhole itself becomes a target for vandalism and the locking mechanism is insufficient to prevent unauthorized opening
Solution Approach 1:
The patent removes the conventional keyhole from the control panel door entirely. Instead, a wireless communication interface is provided on the outer surface of the door, allowing the door to be opened wirelessly without any physical keyhole. This extraction of the keyhole eliminates the vulnerability to keyhole-related vandalism while maintaining security through wireless authentication mechanisms.
Solution Approach 2:
The patent replaces the mechanical keyhole locking system with an electronic wireless communication system. The wireless interface allows authentication and door operation through wireless signals, substituting the mechanical key insertion and turning mechanism with an electronic system that is resistant to physical tampering and vandalism.
2Reliability
If the control panel is locked with a conventional locking mechanism, then unauthorized access is prevented, but the locking mechanism itself can be tampered with and the door can be opened by inserting foreign objects into the keyhole
Solution Approach 1:
The patent extracts the keyhole component entirely from the system, eliminating the possibility of inserting foreign objects or tampering with the locking mechanism through the keyhole. The wireless interface provides an alternative authentication method that does not rely on physical key insertion, thereby preventing this category of tampering.
3Object-affected harmful factors
If a wireless control system is implemented without a keyhole, then protection against vandalism is significantly enhanced, but the system requires wireless communication infrastructure and electronic components
Solution Approach 1:
The patent substitutes the mechanical keyhole system with an electronic wireless communication system. The wireless interface includes necessary electronic components for signal transmission and reception, authentication, and control. While this introduces electronic complexity, it eliminates the physical vulnerabilities of the mechanical system and provides superior protection against vandalism and tampering.
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 solution significantly enhances protection against vandalism by providing a secure, keyhole-less locking system that remains functional during power outages and is resistant to tampering, while maintaining a seamless appearance within the doorframe.
Implementation Method 1
an electrically controllable actuator connected to the arresting means, the actuator being adapted to move the arresting means in response to a wireless control signal
Implementation Method 2
The control panel has a spring, the force brought about by which tries to displace the arresting means towards the releasing position
Implementation Method 3
the arresting means is adapted so that the gravity being exerted on the arresting means tries to displace the arresting means towards the releasing position
