Spring Tine Furrow Closer Lateral Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing harrowing devices for soil tillage and sawing equipment face issues with insufficient lateral stabilization and risk of the stabilizing strut slipping off the harrow tines, leading to inadequate deflection control and attachment security.
Innovation Solution
The stabilizing strut is arranged partially within a spring coil of larger diameter, with angled surface elements and strategically positioned openings for secure attachment, ensuring improved lateral stabilization and non-slip engagement with the harrow tines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the stabilizing strut is arranged on the spring coil with standard diameter, then the device complexity is reduced, but the lateral stabilization of the harrow tines is insufficient
Solution Approach 1:
The patent applies local quality by creating a spring coil with a locally enlarged diameter in the transition area where the stabilizing strut is attached. This localized modification provides the necessary stabilization function without requiring the entire spring coil to have a larger diameter, thus maintaining overall device simplicity while achieving improved lateral stability of the harrow tines.
2Reliability
If the stabilizing strut is attached to the harrow tines using conventional methods, then the ease of manufacture is improved, but the attachment security is insufficient and slippage occurs
Solution Approach 1:
The patent applies the nesting principle by positioning the stabilizing strut within the enlarged diameter region of the spring coil. The strut is nested within the coil structure, which provides secure attachment through the geometric constraint of the enlarged section, preventing slippage while maintaining a simple attachment mechanism that does not require additional fastening components.
3Manufacturing precision
If the spring coil has uniform diameter, then the manufacturing precision is simplified, but the stabilizing strut cannot be securely arranged in the spring coil area
Solution Approach 1:
The patent modifies the spring coil design by creating a localized enlargement in the diameter at the transition area where the stabilizing strut is attached. This local quality change provides the necessary geometric constraint for secure strut arrangement while maintaining uniform diameter in the rest of the coil, thus balancing manufacturing simplicity with attachment security.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances lateral stabilization and secure attachment of the stabilizing strut, providing better deflection control and preventing slippage, thereby improving the overall performance and reliability of the harrowing device.
Implementation Method 1
Several spring coils are arranged between the crossbar and the harrow tines which project downwards in the direction of the ground. Due to the spring coils, the harrow tines can move in any direction relative to the crossbar and evade when hitting obstacles stuck in the ground.

AI summary
The furrow closer has tine elements (1) that are fastened by a fastening element (4) through furrow elements cross-connected at a cross-beam structure (5). Spring coils (6) are extended towards bottom projecting spring tines (3) connected by a stabilizing strut (7) parallel to cross-beam structure. The stabilizing strut is fixed to spring tines, such that diameter of transition region between spring coil and spring tines is larger than diameter of other portions of spring coil. The stabilizing strut is arranged partially in larger diameter portion of the coil.
