Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a machine operator uses traditional sensors to assist with operation, then the operator receives machine data and job site data, but the operator still experiences fatigue and the sensors cannot solve issues related to limited field of vision and obstructed views
Solution Approach 1:
The system enables automatic machine operation where the machine control system autonomously performs operations based on 3-D terrain maps and stereo imaging data, eliminating the need for continuous operator intervention and reducing fatigue while maintaining complete job site awareness
Solution Approach 2:
The patent replaces the operator's visual observation and manual control with automated vision systems (stereo cameras) and control algorithms that process 3-D terrain models to automatically guide machine operations, substituting human sensory and motor functions with mechanical and computational systems
2Measurement precision
If visual sensors are used to recognize terrain features, then the system can detect objects within the sensor range, but the sensors cannot recognize terrain features beyond the limited range or outside the area defined by beacons
Solution Approach 1:
The system transitions from 2-D sensor data to comprehensive 3-D terrain mapping using stereo vision, enabling the machine to perceive and navigate complex three-dimensional terrain features, piles, and trenches with accurate depth and spatial information that extends beyond limited sensor ranges
Solution Approach 2:
The stereo imaging apparatus and 3-D mapping system serve multiple functions: they create detailed terrain maps, identify various terrain features (piles, trenches, obstacles), guide automatic navigation, and provide spatial awareness for operation planning, making the system versatile across different job site conditions and machine types
3Ease of operation
If the machine operator relies on sight to analyze the job site and perform operations, then the operator can make real-time decisions, but the operator's view is obstructed by obstacles at the job site or machine components
Solution Approach 1:
The system introduces stereo cameras and 3-D mapping technology as intermediaries that capture and process visual information from multiple angles and positions, creating a comprehensive digital representation of the job site that compensates for obstructed physical views and provides the control system with complete spatial awareness for real-time decision making
