Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive systems for movable sashes, doors, and flaps require complex settings and programming during commissioning, leading to high construction and control costs, as well as increased space requirements, and lack flexibility in accommodating varying numbers of drive units with different functions.
Innovation Solution
A drive system where drive units generate their own virtual subscriber designations for identification, allowing them to be coupled and networked via a control line, reducing communication effort and enabling the use of standardized units with minimal planning and commissioning effort, and featuring a control device with a microcontroller that simplifies the generation of closing sequence control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If drive units use fixed manufacturer identifiers and complex programming, then identification accuracy is improved, but device complexity and commissioning time increase
Solution Approach 1:
Drive units automatically generate their own virtual subscriber designations without requiring external programming or configuration. The control unit in each drive unit autonomously creates a unique identifier (e.g., based on manufacturing serial numbers or self-generated addresses) and uses it for communication on the control line, eliminating the need for complex commissioning procedures while maintaining accurate identification
Solution Approach 2:
Instead of using complex fixed identifiers, the system uses simplified virtual subscriber designations that copy the essential identification function. These virtual designations are lightweight data structures that replicate the identification capability of complex manufacturer-assigned identifiers without requiring the same level of programming overhead
2Reliability
If drive units are pre-programmed with unique identifiers, then identification reliability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The drive units perform self-identification by automatically generating virtual subscriber designations during initialization. This eliminates the need for manufacturers to pre-program complex unique identifiers into each unit, significantly simplifying the manufacturing process while ensuring reliable identification through the self-generated designations that are unique within the system context
3Ease of operation
If drive systems use standardized units with automatic designation generation, then ease of operation is improved, but communication protocol complexity increases
Solution Approach 1:
The control line serves multiple functions: it transmits control signals, receives status feedback, and automatically exchanges virtual subscriber designations between control device and drive units. This multi-functional use of a single communication channel simplifies the overall system architecture and ease of operation, as users only need to connect the control line without configuring separate communication protocols

AI summary
The invention relates to a drive system (1) and operating method for movable sashes of windows, doors, flaps, or the like in buildings. The drive system (1) comprises several drive units (4-8) and a programmable control device (3), wherein the drive units (4-8) each have a drive element (9) and a programmable control unit (12). The control units (12) are connected to each other and to the control device (3) via a control line (13). Each control unit (12) generates its own virtual participant identifier in the drive system (1) by means of a program, assigns this identifier to itself, and registers with the control device (3) using this participant identifier.
