Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work machines face challenges in achieving precise grading, especially in tight areas with obstacles, and require efficient distribution of grading materials from large heaps, often necessitating additional attachments or manual labor.
Innovation Solution
A grading blade attachment with a knock down blade assembly that includes an upper and rear attachment frame, pivot beam, wheel assemblies, and a movable knock down blade, allowing for both rough and fine grading by transitioning between operative and inoperative positions, controlled by a hydraulic system and controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a stabilizer wheel is used to minimize blade fluctuations and improve precision, then grading precision is improved, but grading speed performance deteriorates when engaging large heaps of material
Solution Approach 1:
The knock down blade assembly is designed to be movable between an operative position (extended forward) and an inoperative position (retracted), allowing the system to dynamically adapt its configuration based on the grading task. This enables the blade to engage large heaps of material effectively when needed while maintaining precision capabilities when fine grading is required
2Productivity
If standard grading attachments are used on large heaps of material, then material distribution becomes challenging, but using alternative attachments or manual labor increases time consumption and reduces efficiency
Solution Approach 1:
The grading blade attachment is designed with multi-functionality, incorporating both a standard grading blade and a movable knock down blade assembly. This allows a single attachment to perform multiple functions: distributing large heaps of material using the knock down blade in operative position, and performing precision grading using the grading blade when the knock down blade is in inoperative position, eliminating the need for multiple attachments or manual intervention
3Productivity
If a single attachment is used to address both rough grading and fine grading, then device complexity increases, but using multiple attachments improves operational efficiency
Solution Approach 1:
The invention merges the knock down blade assembly and the grading blade into a single integrated attachment. The knock down blade assembly is movably coupled to the attachment frame, allowing it to be positioned forward for rough grading and retracted for fine grading. This combination enables both rough grading and fine grading capabilities in one attachment, improving operational efficiency while managing complexity through integrated design

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient grading in small and restricted areas, including surfaces with obstacles, by allowing for rough grading followed by fine finishing, enhancing stability and precision without the need for additional equipment or manual intervention.
Implementation Method 1
The actuator is longitudinally oriented and pivotally coupled to the lift arm support beam on a first actuator end and pivotally coupled about a lift arm pivot axis. The extension and retraction of the actuator pivots the left lift arm and the right lift arm about the pivot axis.
