Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furrow cutter blades often have complex frame structures that lead to wear-related breakage and inefficient furrow geometry, lacking mechanical stability and effective wear management.
Innovation Solution
A blade design featuring a planar fastening region with projecting arms that extend out of and then return to the fastening plane, providing mechanical stability, controlled wear, and a compact structure, allowing for a simple and effective furrow cutting mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a complex frame structure is used for the blade, then the blade can achieve sufficient strength and stability, but the structure becomes complicated and wear-related breakage occurs
Solution Approach 1:
The blade is segmented into a fastening region and one or more projecting arms that extend outward. This segmentation allows the blade to achieve sufficient strength through strategic structural division while maintaining simplicity, avoiding the need for complex frame structures. The projecting arms are designed to distribute mechanical loads effectively, preventing wear-related breakage at connection points.
Solution Approach 2:
The invention extracts the essential functional elements from a complex frame structure, retaining only the necessary components for strength and stability. By removing unnecessary structural elements and focusing on the core load-bearing functions, the blade achieves sufficient strength with a simplified design that is less prone to wear-related failures.
2Stability of the object's composition
If the arm extends out of the fastening plane and then back, then mechanical stability is improved and controlled wear is achieved, but the blade design becomes more complex
Solution Approach 1:
The arm extends out of the fastening plane into a third dimension, creating a spatial configuration that improves mechanical stability. This dimensional transition allows the blade to achieve better load distribution and wear control by utilizing three-dimensional space efficiently, rather than being constrained to a two-dimensional plane.
3Volume of moving object
If a short driveshaft is used due to the arm extending out of the fastening plane, then the structure becomes more compact and stable, but the transmission arrangement becomes more challenging
Solution Approach 1:
The transmission system is designed to accommodate the dynamic spatial relationship created by the arm extending out of the fastening plane. The transmission arrangement adapts to the compact configuration, maintaining functional effectiveness while working within the constrained space imposed by the shortened driveshaft.

AI summary
A blade for a furrow cutter has a planar fastening region which is located in a fastening plane. The blade is driven in rotation via a transmission arranged in a transmission housing. The fastening plans separates a first region of the furrow cutter from a second region of the furrow cutter. The transmission is arranged in the first region. The blade has at least one arm projecting from the fastening region and having a free end. The arm has a first segment which extends out of the fastening plane into the second region. A simple structure, a good cutting result and a high service life are achieved when the arm has a second segment in which the arm extends back in the direction of the fastening plane.
