Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Seed-planting implements face challenges in adjusting the penetration depth of closing discs, which affects the performance of furrow closure, particularly due to variations in field conditions and implement operations.
Innovation Solution
A system and method that includes a controller and actuator to adjust the penetration depth of closing discs based on inputs from sensors monitoring field conditions and implement operations, such as soil moisture, down force, and furrow depth, allowing real-time adjustments to optimize furrow closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the penetration depth of closing discs is adjusted manually or fixed, then the device complexity is reduced, but the adaptability to varying field conditions and implement operations deteriorates
Solution Approach 1:
The closing disc penetration depth is made dynamically adjustable through an actuator system that can modify the depth in real-time based on sensor feedback about field conditions and implement operation parameters, transforming a static system into a dynamic one that adapts to changing conditions
Solution Approach 2:
A feedback control system is implemented where sensors monitor field conditions (soil moisture, hardness) and implement operations (travel speed, down force), and this information is used by a controller to automatically adjust the closing disc penetration depth via an actuator, creating a closed-loop control system
2Reliability
If the penetration depth of closing discs is increased to improve furrow closure, then the effectiveness of furrow closure is improved, but the risk of damaging the seed or excessive soil compaction increases
Solution Approach 1:
The system uses sensors to monitor furrow closure quality and soil conditions, providing feedback to a controller that automatically adjusts closing disc penetration depth to optimize closure effectiveness while preventing excessive depth that could damage seeds or cause harmful soil compaction
Solution Approach 2:
The system dynamically changes the penetration depth parameter of the closing discs based on real-time sensor data about soil conditions and furrow characteristics, adjusting this parameter to achieve optimal closure without causing harmful effects
3Productivity
If the penetration depth of closing discs is adjusted in real-time based on sensor input, then the productivity and seed-to-soil contact are improved, but the device complexity and cost increase
Solution Approach 1:
Real-time sensor feedback about soil conditions, implement operation parameters, and furrow characteristics is processed by a controller that automatically adjusts closing disc penetration depth, enabling adaptive optimization of seed-to-soil contact and planting efficiency without manual intervention
Solution Approach 2:
The system performs self-adjustment of closing disc penetration depth using onboard sensors and automated control, eliminating the need for manual adjustment by operators and enabling the implement to optimize its own performance based on actual field conditions

AI summary
In one aspect, a system for adjusting closing disc penetration depth of a seed-planting implement may include a furrow closing assembly having at least one closing disc configured to penetrate the soil in a manner that closes a furrow formed in the soil by the seed-planting implement. The system may also include an actuator configured to adjust a penetration depth of the at least one closing disc. Furthermore, the system may include a controller configured to receive an input indicative of at least one of an operation of the seed-planting implement or a field condition of a field across which the seed-planting implement is being moved. Additionally, the controller may be further configured to control an operation of the actuator in a manner that adjusts the penetration depth of the at least one closing disc based on the received input.
