Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple levers and accelerators are operated to control wheel loader motions, then the wheel loader can perform excavation and loading works, but the operation becomes complex and requires advanced skills
Solution Approach 1:
The patent creates a virtual copy of the wheel loader's motion state through a display system that generates 3D model images. This virtual representation allows operators to observe the actual motion state without directly managing multiple levers and accelerators, thereby simplifying operation while maintaining control capability.
Solution Approach 2:
The system provides real-time visual feedback by displaying the current motion state of the wheel loader through processed images from multiple cameras. This feedback loop enables operators to understand the machine's state and adjust controls more easily, reducing the skill requirement while maintaining precise control.
2Productivity
If a support image is provided to help operators recognize motion state, then operator training is improved, but the system complexity increases
Solution Approach 1:
The display system serves multiple functions: it provides real-time motion state visualization for operator training, enables remote monitoring, and supports both novice and experienced operators. This multi-functionality justifies the added system complexity by delivering value across multiple operational scenarios.
Solution Approach 2:
The system transforms 2D camera images into 3D model representations, adding a dimensional layer of information that clearly depicts the wheel loader's motion state. This dimensional transformation makes the motion state more intuitive and easier to understand, improving training efficiency without requiring excessive system complexity.
3Measurement precision
If multiple cameras are used to capture motion state information, then the motion state can be accurately represented, but the system complexity and data processing requirements increase
Solution Approach 1:
The patent merges data from multiple cameras by processing their images through a common algorithm that generates a unified 3D model representation. This consolidation approach maintains measurement precision while reducing the effective complexity by treating multiple camera inputs as a single integrated system rather than separate complex subsystems.
