Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the successive approximation method is used to calculate the digging start position, then the digging start position can be determined with appropriate load, but the computational load on the controller becomes excessive
Solution Approach 1:
The patent segments the complex successive approximation calculation into simpler components by using pre-stored target parameter data that defines relationships between movement distance and digging parameters. This divides the computational task from a complex iterative process into simpler data retrieval and calculation steps, reducing the controller's computational load while still determining appropriate digging start positions
Solution Approach 2:
The patent applies preliminary action by pre-calculating and storing target parameter data in advance. Instead of performing complex calculations in real-time during operation, the system prepares the necessary parameter relationships beforehand, allowing the controller to quickly determine digging start positions during actual work without excessive computational burden
2Measurement precision
If the digging start position is selected by skilled experience, then appropriate digging start position can be determined, but it is not easy for operators with little experience to select suitable digging start position
Solution Approach 1:
The system enables self-service by automatically determining the digging start position based on pre-stored target parameter data and current work conditions. This eliminates the need for operators to rely on personal experience or skill, as the system independently calculates and provides the optimal digging start position, making operation equally easy for operators of all experience levels
Solution Approach 2:
The patent implements feedback by using the controller to monitor current work conditions and automatically adjust the digging start position recommendations based on target parameter data. This closed-loop approach ensures accurate digging start position selection while removing the burden from operators, as the system continuously adapts based on actual working conditions

AI summary
A control system for a work vehicle includes a storage device and a controller in communication with the storage device. The storage device stores target parameter data defining a relationship between a movement distance of the work vehicle and a target parameter related to a target digging amount of a work implement of the work vehicle. The target parameter data includes digging time data defining a relationship between the movement distance of the work vehicle within a predetermined digging area and the target parameter. The controller determines a target return distance from a distance of the digging area defined in the target parameter data, and determines a position returned from a predetermined reference position by the target return distance as a recommended digging start position.
