Telescopic Auxiliary Blade Layout for Faster Motor Grading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor graders struggle to efficiently process light and pliable materials, leading to compromised workmanship quality and increased fuel consumption at higher speeds.
Innovation Solution
Equipping the motor grader with at least one auxiliary levelling blade that slides laterally parallel to the main blade, extending its working surface area through telescopic motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the operator increases the vehicle speed to process light and pliable materials faster, then processing time is reduced, but workmanship quality is compromised and fuel consumption increases
Solution Approach 1:
The single levelling blade is segmented into a main blade and at least one auxiliary blade that can be deployed independently. This segmentation allows the system to process light materials with the auxiliary blade at higher speeds while maintaining quality, or use the main blade for heavier materials requiring slower processing
Solution Approach 2:
The auxiliary blade is designed to be dynamically deployable and retractable relative to the main blade. This dynamic configuration allows the operator to adapt the blade assembly to different material conditions and speed requirements, maintaining workmanship quality across varying processing speeds
2Productivity
If the operator increases the vehicle speed to reduce processing time, then productivity increases, but fuel consumption increases
Solution Approach 1:
By segmenting the blade system into main and auxiliary blades, the vehicle can process materials more efficiently at higher speeds when using the auxiliary blade, thereby increasing throughput without the same penalty in fuel consumption that would occur with a single blade system
3Productivity
If the levelling blade length is increased to treat larger surface area, then productivity increases, but device complexity increases
Solution Approach 1:
The auxiliary blade is nested within or alongside the main blade structure, allowing it to be stored in a compact configuration when not in use. This nesting arrangement increases the effective working surface area when deployed while avoiding the complexity of a permanently extended blade structure
Solution Approach 2:
The telescopic deployment mechanism allows the blade system to dynamically adjust its length, providing extended surface area coverage when needed while maintaining a compact form when the auxiliary blade is retracted, thus avoiding permanent structural complexity
