Snow Wing and Moldboard Coordination for Motor Graders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for operating motor graders, such as those disclosed in U.S. Patent Publication No. 20180106014, fail to provide effective coordination of components like snow wings and moldboards, making it difficult for operators to efficiently remove material from a surface.
Innovation Solution
A system and method that includes determining a set of parameters for operating a grading machine, positioning a snow wing in alignment or parallel with a moldboard, and configuring the machine to travel on a surface to effectively remove material, utilizing a processor and memory to autonomously or partially autonomously operate the machine based on these parameters.

Engineering Contradiction Analysis
1Productivity
If multiple operating parameters (articulation angle, moldboard angle, wheel lean) are coordinated to position the snow wing in alignment with the moldboard, then material removal effectiveness is improved, but operator skill requirement increases
Solution Approach 1:
The system automatically determines and adjusts the snow wing position based on collected operating parameters without requiring manual coordination by the operator. The controller autonomously calculates the optimal snow wing angle relative to the moldboard and executes the positioning, allowing the machine to serve itself rather than requiring skilled operator intervention for complex multi-parameter coordination
Solution Approach 2:
The manual mechanical coordination of multiple operating parameters by the operator is replaced with an automated electronic control system. The controller receives input parameters, processes them through software algorithms, and automatically adjusts the snow wing positioning, substituting the operator's manual mechanical adjustment process with an automated electronic control mechanism
2Productivity
If the snow wing is positioned to form a specific acute angle with the moldboard for effective material removal, then grading performance is improved, but system complexity increases
Solution Approach 1:
The controller serves multiple functions: it collects operating parameters from various sensors, determines the optimal snow wing position based on these parameters, executes the positioning command, and can adapt to different operating conditions. This multi-functionality consolidates what would otherwise require separate complex subsystems into a single universal control unit, improving grading performance without proportionally increasing overall system complexity
Solution Approach 2:
The system dynamically adjusts the snow wing angle parameter based on collected operating conditions. Rather than requiring a complex mechanical linkage system to maintain fixed geometric relationships, the control system changes the angular parameter electronically based on real-time conditions, achieving effective material removal while keeping the physical mechanical structure relatively simple
