Load Cell Backing Plate for Consistent Mounting Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing row units in traditional planters are not designed for high-speed and precision farming, leading to inconsistent load cell readings due to varying surface geometries, which affects the accuracy of ground contact force measurement and downforce system control.
Innovation Solution
A backing plate or adaptor is introduced to provide a consistent surface for mounting a load cell on the row unit, with multiple contact points and alignment pins to ensure accurate and precise measurements, while maintaining structural integrity and compatibility with existing equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a load cell is mounted directly on the existing row unit surface, then the mounting process is simple, but the load cell readings are inconsistent due to varying surface geometries
Solution Approach 1:
The patent introduces a backing plate as an intermediary component between the row unit surface and the load cell. This backing plate provides a consistent, flat mounting surface for the load cell while adapting to the varying geometries of existing row units. The plate includes multiple contact points that distribute loads evenly and maintain geometric consistency, thereby resolving the contradiction between simple mounting and measurement precision.
2Productivity
If high-speed precision farming technologies are implemented, then yields and efficiency are maximized, but the cost becomes prohibitive
Solution Approach 1:
The patent segments the precision farming system into modular components, with the backing plate serving as a standalone adapter that can be added to existing row units. This segmentation allows farmers to retrof it current equipment with precision measurement capabilities rather than replacing entire systems, thereby maintaining productivity benefits while reducing the overall device complexity and cost.
Solution Approach 2:
The backing plate is designed as a universal component that can be adapted to multiple row unit configurations and geometries. By creating a multi-functional adapter that works with various existing equipment designs, the system enables precision farming capabilities across different platforms without requiring specialized expensive equipment for each configuration.
3Adaptability or versatility
If existing row units are retrofitted with load cells for precision agriculture, then high-speed planting compliance is achieved, but the structural integrity and compatibility must be maintained
Solution Approach 1:
The backing plate employs local quality by concentrating structural reinforcement at specific contact points and load transfer areas. The plate features strategically positioned ribs, contact points, and mounting areas that provide localized strength where needed while maintaining overall compatibility with various row unit structures. This approach ensures structural integrity is maintained at critical locations without requiring the entire assembly to be overly robust.
