Variable-Rigidity Equine Shoe with Metal-Polymer Composite Support

Solution Overview

Problem

Traditional horseshoes made of metal or urethane suffer from excessive rigidity, lack of traction, undue weight, and durability issues, while urethane-soled shoes face additional problems like nail penetration and limited flexion, leading to shoe failure.

Innovation Solution

An equine shoe design with a rigid distal zone corresponding to the coffin bone and a less rigid proximal zone, featuring a polymer sole and a metal core with fenestrations for nail attachment, providing improved flexibility and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional metal horseshoes are used, then durability and structural support are improved, but rigidity is excessive and natural hoof flexion is restricted

Engineering Contradiction:

Improvestructural supportVSAvoidrigidity

Core Design Contradiction:

StrengthVSStability of the object's composition

Solution Approach 1:

The horseshoe combines metal and polymer materials in a single structure. The metal components (plates, bars, or wires) provide structural support and durability, while the polymer components provide flexibility and shock absorption. This composite construction resolves the contradiction by allowing the shoe to be both strong and flexible simultaneously.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

Different regions of the horseshoe have different material properties. The distal portion (near the toe) uses more flexible materials to allow natural hoof expansion and contraction, while the proximal portion (near the heel) uses more rigid materials for structural support. This local differentiation resolves the rigidity-flexibility contradiction.

Inventive Principle:

Principle #3Local quality

2Stability of the object's composition

If urethane-soled shoes are used, then flexibility and shock absorption are improved, but durability and structural support deteriorate

Engineering Contradiction:

Solution Approach 1:

The horseshoe combines metal and polymer materials in a single structure. The metal components (plates, bars, or wires) provide structural support and durability, while the polymer components provide flexibility and shock absorption. This composite construction resolves the contradiction by allowing the shoe to be both strong and flexible simultaneously.

Inventive Principle:

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The horseshoe combines metal and polymer materials in a single structure. The metal components (plates, bars, or wires) provide structural support and durability, while the polymer components provide flexibility and shock absorption. This composite construction resolves the contradiction by allowing the shoe to be both strong and flexible simultaneously.

Inventive Principle:
