Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a material movement plan is executed without quantitative analysis of work surface characteristics, then the operation can proceed without complex measurement systems, but the accuracy and efficiency of material movement deteriorates
Solution Approach 1:
The system implements feedback by comparing actual work surface measurements with target profile specifications, then using this comparison data to adjust and optimize material movement operations in real-time, improving measurement precision through continuous validation
Solution Approach 2:
The patent replaces complex mechanical measurement systems with sensor-based detection systems that use optical, electromagnetic, or other non-mechanical fields to characterize work surfaces, maintaining high measurement precision while reducing mechanical complexity
2Productivity
If the material movement plan is adjusted frequently based on real-time analysis, then the efficiency and effectiveness of material movement improves, but the complexity of control systems increases
Solution Approach 1:
The system performs preliminary characterization of work surface conditions and pre-calculates optimal movement parameters before actual material movement begins, allowing efficient real-time adjustments without requiring complex dynamic control systems during operation
Solution Approach 2:
The patent optimizes material movement efficiency by dynamically adjusting operational parameters such as machine speed, cutting depth, and path planning based on real-time work surface analysis, achieving high productivity through parameter optimization rather than system complexity
3Manufacturing precision
If quantitative evaluation of target profile is implemented, then the accuracy of material movement assessment improves, but the time required for analysis increases
Solution Approach 1:
The system implements selective quantitative analysis by focusing measurements and evaluations only on critical portions of the work surface and key performance parameters, achieving sufficient manufacturing precision without requiring complete comprehensive analysis that would consume excessive time

AI summary
A system for evaluating a target profile for moving material with a work implement along a path includes a position sensor and a controller. The controller is configured to utilize a planning system to determine the target profile, receive position signals from the position sensor, and determine from the position signals an actual profile indicative of the work surface after the work implement is moved along the path to move a volume of material. The controller is further configured to compare the target profile to the actual profile, determine at least two performance factor scores based upon a difference between the target profile and the actual profile, and generate a quantitative evaluation of the target profile based upon the at least two performance factor scores.
