Trailer Saddle Actuator for Simultaneous Harvesting Head Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trailers require manual, time-consuming adjustment of saddles to accommodate different agricultural harvesting heads, making the process impractical and unsafe, especially when handling wider equipment.
Innovation Solution
A trailer with a pair of adjustable saddles connected by a telescoping rod and actuator, allowing simultaneous movement and remote control operation to align with the harvesting head's support structure, enabling quick and precise positioning without manual alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual adjustment of saddles is used, then the structure is simple, but the adjustment process is time-consuming and reduces productivity
Solution Approach 1:
Two separate saddles are connected by a telescoping rod to move simultaneously as a unified system. The rod merges the adjustment operations of both saddles, so that one actuator movement adjusts both saddles at the same time, doubling the adjustment speed while maintaining structural simplicity
Solution Approach 2:
The manual mechanical adjustment system is replaced with an automated actuator system. The actuator uses mechanical advantage through a rack and pinion mechanism to convert rotational motion into linear motion, automatically positioning the saddles without manual intervention, thus improving productivity while adding controlled complexity
2Measurement precision
If individual saddle adjustment is used, then the control is simple, but the positioning precision for wide heads is insufficient and unsafe
Solution Approach 1:
The telescoping rod connects both saddles to move in unison, ensuring symmetric and precise positioning relative to the centerline of the trailer. This merged movement system maintains equal spacing and alignment, providing accurate positioning for wide heads without requiring complex individual adjustment procedures
Solution Approach 2:
The saddle positioning system transitions from static manual adjustment to dynamic actuator-controlled movement. The actuator can precisely control the position of both saddles simultaneously, allowing accurate positioning adaptability for different head widths while simplifying the operator's task to merely triggering the automatic positioning
3Adaptability or versatility
If multiple separate actuators are used for each saddle, then the independent control is flexible, but the device complexity and cost increase
Solution Approach 1:
One actuator is merged to control both saddles through the connecting telescoping rod. This single actuator system provides synchronized adjustment of both saddles, maintaining flexibility for different head configurations while halving the number of actuators needed, thus reducing complexity and cost
Solution Approach 2:
The single actuator performs multiple functions: it adjusts both saddles simultaneously, controls the telescoping rod extension, and positions the entire saddle assembly. This multi-functional design provides the versatility of multiple actuators with the simplicity of a single control device

AI summary
A trailer for transporting an agricultural harvesting head includes a pair of saddles for supporting the head. The saddles are adjustably mounted on the trailer frame and are simultaneously moved together by an actuator operated by a remote control. The saddles are connected by telescoping rod sections so that the spacing between the saddles is adjustable.
