Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation of construction vehicles is used, then operational flexibility and human control are maintained, but workplace safety deteriorates in hazardous work sites
Solution Approach 1:
The construction vehicle is equipped with autonomous navigation capabilities that allow it to perform tasks independently without continuous human intervention. The vehicle uses sensors, GPS, and onboard processors to navigate work sites, avoid obstacles, and complete designated tasks autonomously, thereby improving workplace safety by removing operators from hazardous environments while maintaining operational effectiveness
Solution Approach 2:
A remote operation system serves as an intermediary between the human operator and the construction vehicle. This system allows operators to control vehicles from safe, remote locations using wireless communication technologies, thereby maintaining human control and flexibility while improving workplace safety by eliminating the need for operators to be physically present in hazardous zones
2Productivity
If autonomous operation systems are added to construction vehicles, then workplace safety and operational efficiency are improved, but device complexity increases
Solution Approach 1:
The autonomous operation system is designed to be universally applicable across different construction vehicle types. The system integrates multiple functions including navigation, obstacle detection, task execution, and communication into a single multi-functional platform, thereby improving productivity without proportionally increasing complexity through functional integration rather than additive complexity
Solution Approach 2:
Traditional mechanical control systems are replaced with electronic and software-based autonomous operation systems. Sensors, GPS, and onboard processors substitute for manual mechanical controls, enabling automated navigation and task execution. This substitution reduces the complexity of mechanical linkages and controls while improving operational efficiency through precise electronic control and automation
3Extent of automation
If customized hardware is added to enable autonomous operation, then autonomous capability is achieved, but manufacturing cost and device complexity increase
Solution Approach 1:
The autonomous operation system is divided into modular, standardized components that can be independently manufactured and assembled. Sensors, processors, and control units are designed as separate modules that can be produced through standard manufacturing processes, thereby reducing manufacturing costs and complexity while maintaining full autonomous operation capability through systematic integration of these standardized parts

AI summary
A system for autonomous or semi-autonomous operation of a vehicle is disclosed. The system includes a machine automation portal (MAP) application configured to enable a computing device to (a) display a map of a work site and (b) provide a graphical user interface that enables a user to (i) define a boundary of an autonomous operating zone on the map and (ii) define a boundary of one or more exclusion zones. The system also includes a robotics processing unit configured to (a) receive the boundary of the autonomous operating zone and the boundary of each exclusion zone from the computing device, (b) generate a planned command path that the vehicle will travel to perform a task within the autonomous operating zone while avoiding each exclusion zone, and (c) control operation of the vehicle so that the vehicle travels the planned command path to perform the task.
