Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Positioning and orienting the blade of a grading machine is a complex and time-consuming task that requires significant experience and expertise, as it involves adjusting multiple parameters such as blade height, angle, pitch, and sideshift, which can be inefficient and labor-intensive.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual blade positioning and orientation adjustments are made by the operator, then the blade can be positioned for different grading tasks, but the process becomes complex and time-consuming requiring significant experience and expertise
Solution Approach 1:
The control system automatically determines the grading machine's location using a location sensor and retrieves pre-stored blade parameters from memory, enabling the system to self-adjust blade height, angle, pitch, and sideshift without operator intervention. This eliminates the need for manual positioning while reducing time loss and operational complexity.
Solution Approach 2:
The patent replaces manual mechanical adjustment operations with an automated control system that uses electronic sensors, memory storage, and actuator control. The location sensor substitutes for operator spatial awareness, and the control system substitutes for operator decision-making, transforming a manual mechanical task into an automated electronic control process.
2Adaptability or versatility
If multiple blade parameters (height, angle, pitch, sideshift) are manually adjusted to achieve optimal positioning, then the blade can be configured for different grading tasks, but the device complexity and operator expertise requirements increase
Solution Approach 1:
The control system pre-stores optimal blade parameters (height, angle, pitch, sideshift) in memory for various grading tasks and locations. When the machine reaches a stored location, the system automatically retrieves and applies the pre-configured parameters, eliminating the need for complex real-time adjustments while maintaining full adaptability across different grading scenarios.
Solution Approach 2:
The control system serves multiple functions: it determines machine location, retrieves stored parameters, controls multiple blade adjustment mechanisms simultaneously, and adapts to various grading tasks. This multi-functional integration reduces the need for separate manual operations for each parameter while maintaining comprehensive adaptability.
3Productivity
If automatic control system is implemented to set blade parameters based on machine location, then blade positioning efficiency and precision are improved, but the device complexity increases
Solution Approach 1:
The location sensor continuously monitors the grading machine's position and provides feedback to the control system. Based on this feedback, the control system automatically retrieves appropriate blade parameters from memory and adjusts the blade configuration accordingly. This closed-loop feedback mechanism enables precise automatic positioning while keeping the system architecture relatively simple through modular sensor-actuator-controller integration.
