Solution Approach 1:

The autonomous machine performs self-scheduling by automatically determining when and where to execute maintenance tasks based on sensor data and operational conditions, eliminating the need for external user scheduling while maintaining effective maintenance through autonomous decision-making

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The scheduling mechanism dynamically adapts to changing operational conditions by continuously monitoring sensor data and adjusting maintenance schedules in real-time, allowing the system to respond to varying work region conditions without requiring complex pre-planned schedules

Inventive Principle:
Principle #15Dynamics

2Extent of automation

If autonomous machines require user input for scheduling, then scheduling accuracy improves, but operational autonomy deteriorates

Engineering Contradiction:

Solution Approach 1:

The system autonomously generates and executes maintenance schedules without requiring user input by using its own sensor data and operational information to determine optimal maintenance timing and locations, fully实现ing self-service scheduling

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The scheduling system continuously receives feedback from sensors monitoring work region conditions and machine status, using this feedback to automatically adjust and optimize maintenance schedules without external intervention, closing the control loop for autonomous operation

Inventive Principle:
Principle #23Feedback

3Reliability

If autonomous machines adapt to changing conditions, then maintenance quality improves, but system complexity increases

Engineering Contradiction:
