Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent replaces software-controlled operations with hardware-based control logic integrated into the bus interface unit. This substitution of software (mechanical/electronic control) with dedicated hardware circuitry eliminates the jitter and throughput limitations inherent in software-controlled systems while maintaining operational simplicity through automated hardware-based data processing and transmission.

3Device complexity

If control functions are centralized in external units, then device complexity is reduced, but load on external units increases

Engineering Contradiction:

Improvedevice complexityVSAvoidload on external units

Core Design Contradiction:

Device complexityVSUse of energy by moving object

Solution Approach 1:

The patent segments control functions by integrating dedicated control logic directly into the bus interface unit. This segmentation separates control responsibilities from external processing units, allowing the bus interface unit to autonomously handle data processing, protocol management, and transmission control. The result is a distribution of computational load that reduces the burden on external units while maintaining manageable device complexity through modular functional separation.

Inventive Principle:

AI summary

A bus interface unit for exchanging data via a bus system includes at least one bus control unit for connection to the bus system, having a control unit that is configured to output data received via the bus control unit from the bus system, and/or data derived therefrom, to an external unit, and/or to output data obtained from an external unit, and/or data derived therefrom, via the bus control unit to the bus system.
