Escape Route Door Lock Bus Control for Selective Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems for door locks lack a material-saving and simple method for enabling escape routing for multiple doors during emergency situations.
Innovation Solution
A security system where multiple door locking controls and triggering elements are connected via a common bus system, allowing selective unlocking of door locks by assigning door locking controls to triggering elements, ensuring that only the relevant door locks are unlocked upon activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate bus system is required for each door lock, then reliable control of each door lock is achieved, but system complexity and material consumption increase
Solution Approach 1:
The patent combines multiple door lock controls and triggering elements into a single common bus system. Instead of requiring separate bus systems for each door lock, the invention integrates them all into one shared communication network, reducing overall system complexity while maintaining individual control capability through addressing schemes.
Solution Approach 2:
The common bus system serves multiple functions: it provides communication between triggering elements and door lock controls, enables selective addressing of individual door locks, and supports both normal operation and emergency unlocking functions through a single infrastructure.
2Reliability
If all door locks are unlocked when an emergency button is pressed, then escape route security is maximized, but unnecessary unlocking of irrelevant doors occurs
Solution Approach 1:
The patent implements local quality by enabling selective unlocking of specific door locks based on which triggering element is activated. Each triggering element is assigned to control specific door lock(s), allowing the system to provide precisely the right level of unlocking - not too little for safety, not too much for control - depending on the local emergency situation at each door.
Solution Approach 2:
The system changes the parameter of door lock state from a static all-or-nothing approach to a dynamic selective approach. By modifying which door locks are unlocked based on the specific triggering element activated, the system adapts the unlocking behavior to match the actual emergency situation, improving both safety and operational precision.
3Loss of substance
If multiple door locks are connected to a common bus system, then material consumption is reduced, but selective assignment and control becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-establishing assignment relationships between triggering elements and door lock controls during system setup. This preliminary configuration allows the common bus system to automatically route signals correctly without requiring complex real-time decision-making, reducing operational complexity while maintaining material efficiency.

AI summary
The invention relates to a safety system (1) for controlling and/or monitoring door locks (200) for securing escape routes with door lock controls (201), wherein a door lock control (201) serves to control a locking mechanism (205) which is to be assigned to the door lock control (201), and with release elements (10, 1010, 2010, 3010), in particular emergency buttons (10, 1010, 2010, 3010), wherein, as a result of actuation of a release element (10, 1010, 2010, 3010), control of at least one locking mechanism (205) can be initiated.According to the invention, a number of door locking controls (201) and a number of release elements (10, 1010, 2010, 3010) are connected to each other via a common bus system (400) and the number of door locking controls (201) are assigned to the number of release elements (10, 1010, 2010, 3010) in such a way that when one of the release elements (10, 1010, 2010, 3010) is actuated, only the at least one door locking control (201) assigned to the actuated release element (10, 1010, 2010, 3010) actuates the respective locking mechanism (205) for unlocking.
