Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tractor attachments for cultivation plows lack efficient mechanisms for controlling swivel angle and position, leading to inefficiencies in plowing and transportation.
Innovation Solution
A cultivation plow attachment for tractors with a frame swivel factor and single-swing factor, combined with sensors and control circuits, allows precise control over the plow frame's rotation and position relative to the swivel axis, using hydraulic or pneumatic cylinders and electrically controlled valves to facilitate easier plowing and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the plough frame is kept at maximum distance from the pivot axis for plowing, then plowing effectiveness is improved, but maneuverability during turning and transport deteriorates
Solution Approach 1:
The plough frame's position relative to the pivot axis is made dynamically adjustable through a pivoting actuator that can change the distance between the ploughshares and pivot axis. The system transitions between a first position (maximum distance for plowing) and a second position (minimum distance for turning/transport), allowing optimal configuration for each operational phase.
2Measurement precision
If a detection device with shut-off valve is used for pivot angle control, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical detection devices with shut-off valves with a simplified sensor-based system. Electrical or hydraulic sensors detect the pivot position and send signals to a control circuit, which then actuates the pivoting actuator. This substitution of mechanical complexity with electrical/hydraulic control reduces overall system complexity while maintaining positioning accuracy.
3Ease of manufacture
If the plough frame requires manual positioning for turning, then ease of manufacture is improved, but productivity during turning operations deteriorates
Solution Approach 1:
The system incorporates automatic control where sensors detect pivot position and the control circuit automatically actuates the pivoting actuator to achieve the desired turning position. This self-service automation eliminates manual positioning requirements, significantly improving turning operation efficiency while maintaining reasonable system simplicity through the use of standard sensor and control circuit components.
