Solution Overview

Problem

Traditional methods for fitting horseshoes with clips are lengthy, imprecise, and prone to clip breakage, especially with aluminum fittings, which can cause discomfort and injury to horses due to mechanical stress and difficulty in maintaining clip proximity to the hoof.

Innovation Solution

A method involving a thermoplastic clip with an acute angle (between 30° and 80°) that is heated to adapt to the hoof's surface, allowing closer contact and easier placement, and an abutment device with a flared attachment lug for secure assembly, reducing mechanical stress and enhancing clip durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If clips are placed at 180 degrees on aluminum fittings, then the horseshoe can be manufactured with pre-formed clips, but the clips require strong straightening which weakens them and causes frequent breakage

Engineering Contradiction:
Improvepre-formed clipsVSAvoidclip durability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent changes the angle parameter of clips from the traditional 180 degrees to an acute angle (30-80 degrees). This parameter change allows clips to be formed without strong straightening operations, maintaining their structural integrity and reducing breakage while still enabling pre-manufacturing of the horseshoe with clips attached.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

Instead of straightening clips from a 180-degree position to achieve proper placement, the invention inverts the approach by forming clips directly at the correct acute angle during manufacturing. This eliminates the harmful straightening process that weakens aluminum clips while achieving the same functional result.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If traditional straightening methods are used to position clips, then clips can be placed on the horseshoe, but the process is lengthy and imprecise

Engineering Contradiction:
Improveclip placementVSAvoidfitting duration
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The clips are preliminarily formed at the correct acute angle during horseshoe manufacturing, eliminating the need for time-consuming straightening operations during farrier work. This preliminary action ensures precise angular positioning is achieved in the factory rather than in the field, reducing fitting time and improving precision.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If clips are formed by traditional forging methods, then clips can be created on the horseshoe, but the process is painful for the farrier and imprecise

Engineering Contradiction:
Improveclip formationVSAvoidclip angle precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The invention changes the formation method parameter from traditional cold forging to a process that forms clips at acute angles (30-80 degrees) without requiring painful manual shaping. This can be achieved through specialized forming tools or pre-attached clip components that require minimal manipulation, improving both farrier comfort and angular precision.

Inventive Principle:
Principle #35Parameter changes
