Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seedbed monitoring systems fail to provide an effective and simple solution for ensuring a level and uniform seedbed during tillage operations, leading to potential losses in crop yield due to poor germination and non-uniform plant stands.
Innovation Solution
A seedbed condition monitoring system comprising an agricultural implement with a seedbed floor detection assembly and a seedbed surface detection assembly, coupled to an auxiliary support arm, which includes pivot arms and sensors to detect variations in the seedbed profile, allowing real-time assessment and adjustment of tillage operations to maintain seedbed quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional tillage operations are performed without monitoring, then the operation is simple and quick, but the seedbed quality becomes non-uniform and levelness is poor
Solution Approach 1:
The patent replaces complex mechanical monitoring systems with a simplified sensor-based detection system. The seedbed floor detection assembly uses sensors to detect variations in seedbed floor elevation, converting physical measurements into electrical signals that can be processed by a controller, thereby reducing mechanical complexity while improving measurement precision.
Solution Approach 2:
The detection assembly is designed to be self-adjusting through the pivotal movement of the seedbed tool. As the seedbed tool encounters variations in the seedbed floor, the pivot arm automatically adjusts the tool's position, and the sensor detects this movement, eliminating the need for external adjustment mechanisms and reducing overall system complexity.
2Measurement precision
If a complex monitoring system is implemented, then seedbed monitoring precision is improved, but the system becomes too complex and difficult to operate
Solution Approach 1:
The patent implements a feedback mechanism where the sensor detects pivotal movement of the pivot arm and sends signals to a controller. The controller processes this information and can provide real-time feedback to the operator or automatically adjust the tillage tools to maintain uniform seedbed conditions, thereby improving measurement precision while keeping operation simple through automated control.
Solution Approach 2:
The pivot arm serves as an intermediary mechanism between the seedbed tool and the sensor. It translates physical variations in the seedbed floor into detectable angular movements, simplifying the measurement process while maintaining high detection accuracy through mechanical leverage and geometric relationships.
3Measurement precision
If the seedbed floor detection assembly is positioned behind the ground-engaging tools, then accurate seedbed floor measurement is achieved, but the device complexity increases
Solution Approach 1:
The detection assembly is segmented into independent functional components: the pivot arm, the seedbed tool, and the sensor. This segmentation allows each component to perform its specific function efficiently while reducing overall structural complexity. The modular design enables easy installation and maintenance without requiring complex integration.
Solution Approach 2:
The detection assembly employs dynamic elements, specifically the pivotable seedbed tool and movable pivot arm, rather than fixed rigid structures. This dynamic design allows the system to adapt to varying seedbed conditions automatically, improving measurement precision while reducing the need for complex adjustment mechanisms and support structures.

AI summary
In one aspect, a system for monitoring the condition of a seedbed within a field may include an implement having a plurality of ground-engaging tools supported by the frame, with the implement being configured to create or be traversed across a seedbed extending downwardly within the field from an outer seedbed surface to a seedbed floor. The system may also include an auxiliary support arm coupled to a portion of the frame at or adjacent to the aft end of the frame and a seedbed floor detection assembly coupled to the auxiliary support arm such that the seedbed floor detection assembly is located behind the ground-engaging tools relative to a forward travel direction of the implement. The seedbed floor detection assembly may be configured to detect variations in a profile of the seedbed floor as the implement is moved in the forward travel direction.
