Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system collects wireless communication environment data from all areas of the working area, then the completeness of the wireless communication environment map is improved, but the time and cost required for data collection increase
Solution Approach 1:
The system performs preliminary actions by formulating an operation plan that strategically determines the movement path of the work machine before actual data collection begins. The plan identifies high-priority areas that need wireless communication environment data first, allowing the system to collect data in advance for critical regions while deferring less critical areas, thus reducing overall data collection time while maintaining map completeness.
Solution Approach 2:
The system applies local quality by differentiating between high-priority and low-priority areas in the working area. Instead of uniformly collecting data from all locations, the operation plan focuses data collection efforts on high-priority areas first, allocating resources based on local needs. This allows the system to achieve adequate map completeness for critical regions faster while progressively filling in other areas.
2Productivity
If the system creates a detailed operation plan considering wireless communication environment, then the optimization of movement path is improved, but the complexity of operation planning increases
Solution Approach 1:
The system performs preliminary action by pre-formulating an operation plan that integrates wireless communication environment considerations before the work machine begins its operation. The plan is created in advance based on work requests and priority area information, allowing the system to optimize movement paths without adding real-time complexity during actual execution.
Solution Approach 2:
The system applies local quality by focusing operation plan optimization on high-priority areas rather than attempting to optimize every location uniformly. The plan concentrates computational efforts on regions where wireless communication environment has the greatest impact on work efficiency, reducing overall planning complexity while maintaining productivity optimization where it matters most.
3Productivity
If the system prioritizes data collection in high-priority areas, then the efficiency of operation planning is improved, but the uniformity of data coverage across the working area decreases
Solution Approach 1:
The system explicitly applies local quality by creating differentiated data collection strategies for high-priority and low-priority areas. High-priority areas receive intensified data collection efforts with higher sampling density and frequency, while low-priority areas receive standard coverage. This local differentiation improves operation planning efficiency for critical regions while maintaining adequate, though less dense, coverage elsewhere, achieving a balanced approach to uniformity.
Solution Approach 2:
The system performs preliminary action by pre-identifying high-priority areas and formulating targeted data collection plans before actual data gathering begins. This advance planning allows the system to efficiently allocate resources to areas where data collection has the greatest impact on operation planning efficiency, while ensuring that low-priority areas still receive baseline coverage through the structured plan.

AI summary
A management system of an autonomously movable work machine includes: a processing circuitry, in which the processing circuitry receives a work request, formulates an operation plan of the work machine based on the work request, the operation plan including a movement path of the work machine in a working area of the work machine, assigns the work request to the work machine based on the operation plan, acquires wireless communication environment data on the movement path collected by the work machine, and creates a wireless communication environment map of the working area using the acquired wireless communication environment data. The processing circuitry formulates the operation plan based on a data acquisition state of each section in the working area on the wireless communication environment map.
