Cuboid Fastening Element for Fan Guard Strut Stability

The fastening device is divided into multiple independent parts: a fastening element with clamping mechanism, a fastening means (screw/bolt), and the mounting strut itself. This segmentation allows each component to be optimized for its specific function - the fastening element provides structural support, the clamping mechanism generates compressive forces, and the fastening means secures the connection. This resolves the contradiction by enabling high fatigue strength through specialized components while maintaining reasonable complexity through modular design.

The patent changes the physical state and parameters of the connection by introducing pre-clamping forces through the fastening means. The clamping mechanism generates compressive forces that create friction between contact surfaces, transforming the connection from a simple mechanical joint to a friction-based connection with superior load-bearing capacity. This parameter change (introducing compressive force) dramatically increases fatigue strength without requiring overly complex structures.

The connection system is segmented into standardized components that can be manufactured independently using conventional processes. The fastening element can be produced by casting or molding, the mounting strut by extrusion or bending, and the fastening means by standard fastener manufacturing. This segmentation enables high reliability through optimized component design while maintaining ease of manufacture through standardized production methods and assembly.

The clamping mechanism is designed to automatically generate the necessary clamping forces through the tightening action of the fastening means, without requiring additional actuators or complex mechanisms. The friction between clamped surfaces self-regulates the connection strength, and the deformable fastening element adapts to the mounting strut geometry. This self-service approach achieves high reliability while simplifying manufacturing and assembly.

The fastening device is segmented into exactly two functional parts: the fastening element (providing structural support and clamping surfaces) and the fastening means (providing the tightening mechanism). This minimal segmentation achieves the necessary clamping force and transverse force absorption through the interaction of these two components, without introducing unnecessary complexity. The screw thread itself provides the mechanical advantage needed to generate high clamping forces from modest tightening torques.

The fastening element combines multiple functions in a single component: it provides the clamping surfaces, the structural support for the mounting strut, and the interface for the fastening means. The fastening means combines the tightening function with the locking function through the screw thread geometry. This merging of functions into minimal components achieves high force capacity while keeping the number of parts low and assembly simple.
