Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Farming equipment faces excessive wear and high maintenance costs due to uneven terrain caused by rain and drought, leading to increased operational expenses and limiting profitability.
Innovation Solution
Agricultural implement with multiple rows of disk blades and ripper shanks configured to engage soil transversely, each with specific offset angles, combined with a chopper reel, to level and prepare the field in a single pass, reducing the need for multiple passes and minimizing equipment wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional tillage equipment is used on uneven terrain, then field preparation can be performed, but equipment wear increases and maintenance costs rise
Solution Approach 1:
The tillage equipment is divided into multiple independent working components (disk blades arranged in multiple rows, ripper shanks, chopper reel) that can be individually adjusted and optimized. Each segment handles specific soil preparation tasks, allowing the system to adapt to uneven terrain without overwhelming stress on a single component.
Solution Approach 2:
The disk blades are configured with varying offset angles (first and second offset angles for front rows, third and fourth offset angles for rear rows) to dynamically adapt to terrain variations. The ripper shanks are positioned at specific depths and angles to dynamically respond to soil conditions, reducing impact forces and equipment wear while maintaining effective soil preparation.
2Manufacturing precision
If multiple passes are made to prepare the field, then thorough soil preparation is achieved, but fuel consumption and operational costs increase
Solution Approach 1:
Multiple tillage functions (disking, ripping, chopping, and soil leveling) that traditionally required separate passes are merged into a single integrated equipment assembly. The multi-row disk blades, ripper shanks, and chopper reel work simultaneously in one pass to achieve comprehensive soil preparation, eliminating the need for multiple sequential operations and reducing fuel consumption.
Solution Approach 2:
The equipment assembly serves multiple functions simultaneously: the disk blades cut and mix soil, the ripper shanks break up compacted layers, and the chopper reel incorporates residue. This multi-functional design allows a single pass to accomplish what previously required multiple specialized operations, improving efficiency while reducing energy use.
3Productivity
If aggressive tillage is used to handle uneven terrain, then soil preparation is thorough, but equipment wear and maintenance costs increase
Solution Approach 1:
Different sections of the equipment have locally optimized characteristics: front disk blades have larger offset angles for aggressive initial soil cutting, while rear disk blades have smaller offset angles for finer finishing work. The ripper shanks are positioned at specific depths and angles tailored to local soil conditions. This localized optimization allows effective soil preparation without subjecting all components to maximum stress, thereby reducing overall equipment wear and maintenance requirements.

AI summary
A representative system for preparing a field for planting includes: first disk blades, each exhibiting a first offset angle with respect to a tilling direction; second blades, each exhibiting a second offset angle with respect to the tilling direction; ripper shanks disposed behind the second disk blades; third disk blades disposed behind the ripper shanks, each exhibiting a third offset angle with respect to the tilling direction; fourth disk blades, each exhibiting a fourth offset angle with respect to the tilling direction; and a chopper reel disposed behind the fourth disk blades; wherein, with respect to magnitude, each of the first offset angle and the second offset angle is greater than each of the third offset angle and the fourth offset angle.
