Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural implements face challenges in consistently and precisely tilling and seeding uneven or sloped ground surfaces while maintaining accurate tillage and seeding depths and row spacing, leading to inconsistent performance and potential unseeded or untilled areas.
Innovation Solution
An agricultural implement with an elongated open channel member and a connecting assembly that allows the member to twist about a longitudinal axis, featuring clamping members to secure the flanges and a support frame with wheeled units for stability, ensuring precise engagement and alignment on uneven terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the agricultural implement operates on uneven or sloped ground, then productivity is improved by covering more area, but manufacturing precision deteriorates due to inconsistent tillage depth and row spacing
Solution Approach 1:
The implement incorporates adjustable depth control mechanisms that allow dynamic adjustment of tillage depth for each ground engager. The frame structure includes adjustable linkages and hydraulic or mechanical depth control systems that enable real-time modification of engagement depth based on terrain conditions, maintaining consistent tillage depth while operating across varied terrain to maximize area coverage.
Solution Approach 2:
Each ground engager or module is equipped with independent depth adjustment capabilities, allowing localized optimization of tillage depth according to specific terrain conditions at each position. This enables different sections of the implement to operate at optimally different depths simultaneously, maintaining precision across heterogeneous terrain while preserving overall productivity.
2Manufacturing precision
If the implement uses rigid fixation of ground engagers, then manufacturing precision is improved through stable positioning, but adaptability deteriorates when encountering uneven terrain causing shifting
Solution Approach 1:
The ground engager mounting system incorporates adjustable and movable components that allow the engagers to adapt their position and orientation relative to the frame. This includes adjustable linkages, pivot points, and flexible mounting mechanisms that enable the ground engagers to maintain optimal engagement with the terrain while accommodating variations in ground conditions, thus achieving both positioning precision and terrain adaptability.
Solution Approach 2:
The implement divides the ground engager system into independently adjustable modules or segments. Each segment can be individually positioned and adjusted to accommodate local terrain variations, allowing the overall system to maintain precision across heterogeneous terrain without requiring complete rigidity of the entire ground engager array.
3Manufacturing precision
If the implement uses fixed row spacing configuration, then manufacturing precision is improved through consistent spacing, but adaptability deteriorates on uneven ground causing skewed orientation
Solution Approach 1:
The row spacing system incorporates adjustable mechanisms that allow dynamic modification of spacing between ground engagers. This includes adjustable linkages, movable mounting structures, or hydraulic positioning systems that enable real-time adjustment of row spacing to compensate for terrain variations, maintaining consistent spacing and alignment across uneven ground while preserving the ability to adapt to local conditions.

AI summary
An agricultural implement has (i) an elongated open channel member; and (ii) a connecting assembly comprising a first vertical connector plate positioned against a first vertical side of the open member and a second vertical connector plate positioned against a second vertical side of the open member. When the open member twists about a longitudinal axis, its upper and lower flanges will move within upper and lower channels about upper and lower raised surface areas. A clamping assembly includes: a first clamping member extending horizontally between the first vertical plate and the second vertical plate positioned over and proximate an upper surface of the upper flange; a second clamping member extending over and proximate a lower surface of the lower flange; and a third clamping member extending (i) over and proximate a lower surface of the lower flange or (ii) over and proximate an upper surface of the upper flange.
