Agricultural Tire Stud Geometry for Uniform Soil Compaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural tires result in uneven soil compaction, with higher compaction in the central region of cultivation strips and inadequate distribution of soil compositions, affecting soil uniformity and material deposition.
Innovation Solution
The tire design features stud elements with sections oriented parallel to the running direction and mirror-symmetrical inner sections, forming profile channels to guide soil uniformly, with a balanced penetration depth and geometry to enhance compaction uniformity and facilitate even distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the number of stud elements is increased to improve soil compaction uniformity at lateral ends, then compaction uniformity improves, but excessive compaction occurs preventing water penetration
Solution Approach 1:
The patent applies local quality by differentiating the configuration of stud elements at different locations on the tire tread. Lateral end regions have stud elements with increased density or different geometric arrangements compared to central regions, allowing enhanced compaction uniformity at the edges without causing excessive compaction in the center that would prevent water penetration.
Solution Approach 2:
The tire tread is segmented into different zones (central region and lateral end regions) with distinct stud element configurations. This segmentation allows each region to be optimized independently for its specific compaction requirements, resolving the contradiction between achieving uniformity and avoiding excessive compaction.
2Manufacturing precision
If stud element geometry is modified to improve compaction at lateral ends, then edge compaction improves, but overall soil uniformity deteriorates
Solution Approach 1:
Different stud element geometries are applied to different regions: lateral end regions use configurations optimized for edge compaction uniformity, while central regions use configurations that maintain overall soil uniformity. This local differentiation resolves the contradiction between improving edge compaction and maintaining overall uniformity.
3Ease of manufacture
If conventional tire design is used, then ease of manufacture is maintained, but soil compaction uniformity is insufficient
Solution Approach 1:
The patent modifies parameters of existing stud elements (such as spacing, orientation, or geometric dimensions) rather than introducing entirely new components or manufacturing processes. This allows improved soil compaction uniformity while maintaining relative ease of manufacture through incremental parameter optimization.

AI summary
The invention relates to a tire (30) for an agricultural sowing and/or soil-working device (10), comprising at least one tread (31), in particular a peripheral tread, which can roll in a running direction (L+, L-) of the tire (30), a plurality of peg elements (40) which are arranged at least partly one behind the other between two opposite lateral ends (31A, 31B) of the tread (31) and in the running direction (L+, L-), wherein at least one peg element (40) has at least one transverse section (41) which is formed substantially transversely to the running direction (L+, L-). In order to design a tire (30) for an agricultural sowing and/or soil-working device (10) such that the uniformity of the worked and/or treated cropping soil, in particular the seedbed, is further improved, the at least one peg element (40) has at least one first outer section (42) facing a first lateral end (31A) of the tread (31), said outer section being formed so as to at least partly correspond to the running direction (L+, L-), in particular so as to be at least virtually parallel thereto.
