Interface for a soil working implement with a base and an attachment

The patent applies asymmetry by providing shape coding elements with specific geometric configurations that are asymmetric in nature. The coding elements have distinct shapes and positions that create a unique fit pattern, allowing only compatible base devices and attachments to be connected. This asymmetric design ensures that incompatible combinations (such as low-voltage with high-voltage) physically cannot be connected, thereby preventing malfunctions or damage while maintaining system safety.

The patent applies segmentation by dividing the interface into distinct functional components: the base device interface, the attachment interface, and separate shape coding elements. The shape coding elements are provided as discrete features (such as protrusions, recesses, or coded patterns) that can be independently designed and manufactured. This segmentation allows the safety function to be added without fundamentally redesigning the entire interface structure, thereby limiting the increase in overall complexity.

The patent applies preliminary action by designing the shape coding elements to engage in a specific sequence during the connection process. The coding elements are positioned and dimensioned such that they guide the alignment of the base device and attachment before final engagement. This preliminary alignment action reduces the tolerance requirements for subsequent manufacturing steps, as the shape coding elements themselves perform the preliminary positioning function that would otherwise require high-precision manufacturing.
