Door System Central Control Module Activation for Failover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern door systems face increased complexity and installation effort due to the need for additional devices to provide central intelligence, which is not universally applicable across varying designs.
Innovation Solution
A door system design where at least two devices, such as a door drive and motor-driven lock, are equipped with a central control module, allowing them to control the system and adapt to its size, eliminating the need for an additional device and enabling automatic adaptation to the system's type and configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional device is provided to take over the tasks of central intelligence, then the door system has a dedicated control function, but the acquisition costs increase, the system complexity increases, and the installation effort increases
Solution Approach 1:
The patent applies multi-functionality by enabling existing door system devices (door drive, motor lock, escape door control) to perform both their primary functions and the additional function of central intelligence control. Each device is equipped with a central control module that can be activated based on predetermined criteria, allowing these devices to universally handle control tasks without requiring a dedicated separate controller.
Solution Approach 2:
The patent merges the central intelligence control function with existing door system devices by integrating central control modules into them. This combining of control functionality with already-present devices eliminates the need for an additional separate control device, thereby reducing system complexity while maintaining reliable control.

3Ease of operation
If only one device has the central control module activated, then the control function is clear, but a single point of failure exists
Solution Approach 1:
The patent applies dynamics by making the activation of central control modules dynamic rather than static. Devices can activate or deactivate their central control modules during operation based on predetermined criteria such as device availability, priority sequences, or failure detection. This dynamic activation allows the system to adapt to changing conditions, maintaining control clarity while providing failover capabilities.
Solution Approach 2:
The patent applies preliminary action by establishing predetermined criteria and priority sequences for central control module activation before failures occur. The system pre-configures which devices should activate their control modules under specific conditions, ensuring that when a failure occurs, the appropriate backup device can immediately take over control without confusion or delay.

AI summary
A door system comprises a door, a data communication system for providing a transmission path for data transmission between participants in the data communication system, and at least two devices with an electronic control unit that are connected to the data communication system as participants. At least two of the devices are equipped with a central control module for controlling the door system.
