Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple dedicated input connections are provided for different signal transmitter types, then the control unit can accommodate various transmitter types, but the installation space and device complexity increase
Solution Approach 1:
The control unit employs a universal input connection that can be configured to accept different signal transmitter types through software configuration or switch settings. Instead of providing separate dedicated inputs for each transmitter type, a single multi-functional input is designed that can be adapted to various transmitter types (e.g., push buttons, presence sensors, authorization devices) through configuration parameters, thereby reducing the number of physical connections and minimizing installation space.
Solution Approach 2:
The control unit utilizes configurable switches or software parameters that can be dynamically adjusted to change the function of the input connection. This dynamic configuration allows the same physical input to serve different purposes depending on the installed transmitter type, enabling the system to adapt to different configurations without requiring additional hardware connections or increasing the control unit's physical footprint.
2Adaptability or versatility
If multiple dedicated input connections are provided for different signal transmitter types, then various transmitters can be connected, but the number of connecting cables and routing complexity increase
Solution Approach 1:
By designing a universal input connection that can be configured for different transmitter types, the patent reduces the number of separate cable connections required. Instead of needing distinct cables for push buttons, presence sensors, and authorization devices, a single cable connected to the universal input suffices, as the input's function is determined by configuration rather than physical connection type, thereby simplifying cable routing and reducing overall system complexity.
Solution Approach 2:
The patent extracts the configurability aspect from the physical connection structure. Rather than having the connection type fixed by hardware design, the functional characteristics of the input are separated and made configurable through software or switches. This extraction allows the same physical connection to serve multiple functions, reducing the number of cables needed and simplifying the routing infrastructure.
3Adaptability or versatility
If conventional control units with numerous connections are used, then different signal transmitters can be accommodated, but integration into door or door frame becomes difficult
Solution Approach 1:
The control unit is designed with a universal input connection that can be configured for different transmitter types, reducing the overall size and connection requirements of the unit. This compact, multi-functional design makes it easier to integrate the control unit into door or door frame structures, as less space is required for connections and cable management, and the unit can be installed in tighter spaces within the door assembly.
Solution Approach 2:
The patent combines multiple input functions into a single configurable connection, effectively merging what would traditionally require separate hardware inputs into one unified interface. This consolidation reduces the physical footprint of the control unit and simplifies its integration into door structures, as fewer separate connection points and cable pathways are needed within the confined space of the door or frame.

AI summary
The device (4) has an electromotive drive device (2) which adjusts the building door (1), with signal input for connection of signal generator of preset type to control unit. The control unit is formed in dependence on the signal encoder type of signal transmitter on signal transmitter signal to control the drive device for direct opening of the building door and to authorize opening of door to building. The drive device after authorization opens the building door to control. The control unit for determining the transducer type of signal transmitter is connected to signal input.
