Solution Approach 1:

The system continuously captures 3D measuring data of the terrain and detected elements from previous phases, using this feedback to automatically configure the machine control unit for the next phase. This closed-loop feedback mechanism enables the system to adapt and automate multi-phase operations without requiring manual reconfiguration between phases.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The machine control unit automatically configures itself for the next phase by detecting elements from the previous phase and using operator input to determine the appropriate configuration. This self-service capability eliminates the need for manual intervention to reconfigure the system between phases, significantly reducing operator workload while maintaining high automation levels.

Inventive Principle:

Solution Approach 1:

Instead of requiring complex computer systems to create surface design files, the system captures 3D measuring data of the actual terrain and detected elements, creating a digital copy of the environment. This copied data is then used to automatically configure the machine control unit, simplifying the system while maintaining accurate surface cutting capability.

Solution Approach 1:

The system implements partial automation where the machine control unit automatically configures itself for each phase based on detected elements from the previous phase, while still allowing operator input when needed. This partial automation approach maintains operator flexibility and control while significantly reducing the manual workload and fatigue associated with fully manual multi-phase operations, thereby improving productivity.
