Horseshoe Threaded Stud Plate Spring Dynamic Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional threaded studs for horseshoes fail to provide a secure attachment under high dynamic loads, such as those encountered in show jumping, due to insufficient thread engagement and risk of over-tightening, which can lead to stud loss and hoof injury.
Innovation Solution
A threaded stud with a plate spring integral to the head and threaded portions, where the plate spring's larger outer diameter supports the stud's circumference against the horseshoe, absorbing dynamic loads and preventing over-tightening, and featuring elevations for anti-twist security, ensuring a secure and safe attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional threaded studs with limited thread engagement (2-4 threads) are used in horseshoes, then the structure remains simple and easy to install, but the attachment security deteriorates under high dynamic loads during show jumping
Solution Approach 1:
The stud is divided into functionally distinct segments: a threaded portion for initial attachment, a plate spring portion for load distribution and security, and a head portion for tool engagement. This segmentation allows each part to specialize in its function, with the plate spring providing enhanced reliability without requiring increased thread complexity.
Solution Approach 2:
The solution moves from relying solely on axial thread engagement (one dimension) to incorporating radial support through the plate spring's outer circumference (second dimension). The plate spring's larger outer diameter provides circumferential support against the horseshoe wall, creating a two-dimensional attachment system that dramatically improves security under dynamic loads.
2Strength
If higher torque is applied to secure the threaded stud in the horseshoe, then the attachment strength improves, but the risk of screwing through into the horse's hoof increases
Solution Approach 1:
The plate spring is pre-formed with a larger outer diameter than the threaded portion, creating a built-in mechanical stop before installation. When the stud is inserted, the plate spring's outer circumference contacts the horseshoe wall first, establishing a predetermined depth limit that prevents over-tightening and potential hoof injury regardless of the torque applied.
Solution Approach 2:
The plate spring acts as a cushioning element between the threaded portion and the potential contact point with the horse's hoof. Its elastic properties and geometric design provide a mechanical buffer that absorbs excess torque and prevents the stud from being screwed through the horseshoe into the hoof.
3Reliability
If the outer diameter of the plate spring is made larger than the threaded portion, then the load distribution and anti-over-tightening capability improve, but the device complexity increases
Solution Approach 1:
The plate spring is formed as an integral continuation of the threaded portion, creating a unified monolithic structure. This merging eliminates the need for separate components, fasteners, or assembly steps, while the gradual geometric transition from the threaded portion to the larger-diameter plate spring maintains manufacturing simplicity despite the changed geometry.
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
The threaded stud effectively withstands high dynamic loads, preventing loss and hoof injury, with the plate spring distributing torque and providing a secure hold, even under extreme conditions like jumping and landing.
Implementation Method 1
a plate spring (16) is provided between the head portion (10) and the threaded portion (12), the concave side of which (16) faces the threaded portion (12)

AI summary
Between a threaded section (12) and a head section (10) there is a disk spring (16) integral to the head section section and the threaded section. A concave side of the disk spring is turned towards the threaded section. The outer diameter of the disk spring is greater than the outer diameter of the threaded section.
