Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The brake device incorporates multiple driving interfaces (first driving interface for radial actuation, second driving interface for axial actuation) that can connect to different types of driving devices. This universal design allows the same brake device to be adapted to various vehicle concepts and actuating systems without requiring complete redesign, thereby improving adaptability while managing complexity through standardized multi-functional components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The transmission mechanism is segmented into separate driving interfaces and actuation paths. The first driving interface connects to a first driving device for radial movement of the friction element, while the second driving interface connects to a second driving device for axial movement. This segmentation allows each interface to be independently configured for different vehicle requirements, improving versatility while maintaining manageable complexity through modular design.

Inventive Principle:
