Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed radial distance between input shaft and output shaft is provided in torque transmission device, then the device structure is simplified, but the adaptability to different installation situations is reduced
Solution Approach 1:
The torque transmission device is divided into a first base structure part (housing motor and electrical units) and a second base structure part (housing output shaft and torque transmission mechanism), connected via a detachable fastening interface. This segmentation allows the second part to be exchanged for different installation situations while keeping the first part standardized.
Solution Approach 2:
The first base structure part is designed with a universal fastening interface that can accommodate multiple different second base structure parts. This allows a single standardized motor unit to work with various output configurations (different radial distances, torque transmission ratios, shaft connections) to adapt to different installation situations.
2Adaptability or versatility
If additional torque transmission devices are provided to adapt to different installation situations, then the adaptability is improved, but the device complexity and production costs increase
Solution Approach 1:
By segmenting the door drive into standardized first base structure part and interchangeable second base structure parts, the system provides adaptability through modular exchange rather than adding complex additional torque transmission devices. The fastening interface enables easy connection and disconnection of different configured second parts.
Solution Approach 2:
The system transitions from a fixed, static configuration to a dynamic, reconfigurable system where the second base structure part can be exchanged based on installation requirements. The detachable fastening interface enables this dynamic adaptability without increasing overall device complexity.
3Adaptability or versatility
If a modular system with multiple components is used, then the adaptability to different door types is improved, but the assembly complexity and production costs increase
Solution Approach 1:
The door drive is segmented into a standardized first base structure part and configurable second base structure parts. This segmentation enables series production of the common first part while allowing customization only in the second part, reducing overall production complexity compared to fully modular systems.
Solution Approach 2:
The first base structure part merges the motor, electrical units, and control elements into a single standardized assembly. This merging reduces the number of separate components that need to be managed and assembled, simplifying production and assembly processes while maintaining adaptability through the interchangeable second part.

AI summary
The invention relates to a method for producing a gate drive (14) having a main structure (40) on which a motor (5) comprising a motor shaft (64), an output shaft (80; 111, 113, 115, 117), and a gearbox (94) connecting the motor shaft (64) and the output shaft (80; 111, 113, 115, 117) is fastened. In order to be able to cost-effectively manufacture in large-scale industrial production a gate drive (14) capable of being individually adapted to various installation situations, the following steps are proposed: providing a first main structure part (42) which is constructed identically for each gate drive (14) and on which the motor (50) is fastened, selecting a second main structure part (44) from a range of different second main structure parts (44, 110, 112, 114, 116), which are each provided with an identical fastening interface (46) for fastening to the first main structure part (42) and with different output shafts (80; 111, 113, 115, 117) and/or different distances of a bearing (82) for an output shaft (80, 111, 113, 115, 117) from the fastening interface (46), fastening the first main structure part (42) and the second main structure part (44) together at the fastening interface (46), and connecting the output shaft (80, 111, 113, 115, 117), which is supported on the selected second main structure part (44, 110, 112, 114, 116), to the motor shaft (64) by way of the gearbox. Furthermore, a gate drive module system and an advantageous use of a gate drive produced in such a way are proposed.
