Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous operation systems are implemented in construction vehicles, then workplace safety and operational efficiency are improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by designing a single integrated autonomous operation system that can control multiple different types of construction vehicles (excavators, loaders, dump trucks, etc.) through a common architecture. The system uses standardized interfaces and communication protocols that work across various vehicle types, reducing the need for separate customized systems for each vehicle type while maintaining high safety standards through consistent autonomous monitoring and control mechanisms.
Solution Approach 2:
The autonomous operation system is divided into distinct functional modules including obstacle detection units, path planning modules, vehicle control interfaces, and communication systems. This segmentation allows each component to be optimized independently while maintaining overall system integration, reducing complexity through modular design that can be assembled and maintained more easily than a monolithic system.
2Extent of automation
If customized hardware is added to enable autonomous operation, then autonomous capabilities are achieved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The system uses universal communication protocols and standardized hardware interfaces that can be integrated into existing construction vehicles without requiring completely customized hardware for each application. The autonomous operation platform can be adapted to different vehicle types through software configuration and standardized sensor integration, significantly easing manufacturing and deployment processes.
Solution Approach 2:
The patent introduces an intermediary communication layer that bridges between standard vehicle control systems and autonomous operation requirements. This intermediary layer uses standardized protocols to translate between different vehicle types' control systems and the unified autonomous operation platform, avoiding the need for completely customized hardware integration for each vehicle type.
3Ease of operation
If remote control systems with line-of-sight requirements are used, then vehicle control is achieved, but operational flexibility and productivity are limited
Solution Approach 1:
The patent replaces line-of-sight mechanical control systems with wireless communication-based autonomous operation systems. The system uses wireless data transmission and processing to enable vehicle control without requiring direct visual contact or physical line-of-sight between the operator and vehicle, allowing operations in previously inaccessible or hazardous environments while maintaining full control capability.
Solution Approach 2:
The autonomous operation system enables vehicles to perform repetitive tasks independently through self-navigation, obstacle avoidance, and automated operation sequences. The system can autonomously plan paths, execute tasks, and return to base stations for charging or material transfer without continuous human intervention, dramatically improving productivity while maintaining ease of operation through centralized monitoring capabilities.
4Adaptability or versatility
If autonomous vehicles operate without defined boundaries, then operational flexibility is maintained, but safety and control are compromised
Solution Approach 1:
The system establishes virtual boundaries and operational zones before autonomous vehicle deployment. Operators can pre-define safe operating areas, exclusion zones, and task parameters through a graphical interface, allowing the vehicle to operate flexibly within these predetermined constraints while maintaining safety through automated boundary enforcement and monitoring.
