Solution Overview

Problem

Conventional horseback riding stirrups are ineffective in resisting upward and transverse forces, posing a risk of ejection during rapid movements, especially for novice riders and skilled riders in mounted sports, and existing safety systems fail to reliably resist such forces without interfering with normal riding positions.

Innovation Solution

An inverse stirrup design that attaches to the horse's tack, allowing riders to resist upward and transverse forces by applying pressure to a concave element with the upper surface of their feet, using flexible or semi-flexible straps and potentially reinforced with rigid elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If conventional stirrups are used that hang freely from the saddle, then the rider can rest feet and press down to resist downward forces, but the stirrup cannot resist upward or sideward forces effectively

Engineering Contradiction:
Improveforce resistance capabilityVSAvoidability to resist multiple方向的 forces
Core Design Contradiction:
ForceVSAdaptability or versatility

Solution Approach 1:

The invention inverts the conventional stirrup design by having the stirrup strap attach to the girth strap that passes underneath the horse, rather than hanging freely from the saddle. This inversion allows the stirrup to resist upward forces by transferring them through the girth strap to the horse's body, while the concave element contacts the upper surface of the rider's foot to provide upward support.

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

2Reliability

If the stirrup is designed to resist upward forces by attaching to the girth strap, then rider stability during rapid movements is improved, but the device complexity increases

Engineering Contradiction:
Improverider stabilityVSAvoidstirrup structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention utilizes the girth strap, which is already a necessary component of the saddle system for securing the saddle to the horse, and adds stirrup attachment functionality to it. This multi-functional use of the girth strap avoids adding separate complex attachment mechanisms, thereby improving rider stability while minimizing increases in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If existing safety stirrup systems are implemented, then some upward force resistance is provided, but they interfere with the rider's normal ability to dismount or move in the saddle

Engineering Contradiction:
Improveupward force resistanceVSAvoidrider mobility and dismounting ability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The stirrup design allows dynamic adjustment of the strap tension and positioning. The strap can be loosened or adjusted to accommodate different riding positions and movements, and can be easily released to allow dismounting. This dynamic capability maintains upward force resistance during riding while preserving rider mobility and ease of dismounting.

Inventive Principle:
Principle #15Dynamics

AI summary

An inverse stirrup for use in horseback riding that a horseback rider contacts with the top of the rider's foot to resist upward or transverse force and maintain position on the horse. The inverse stirrup is attached to the horse by means of a circumferential or semi-circumferential strap such as the girth strap passing beneath the horse such that the inverse stirrup resists displacement upward.
