Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lift mechanisms are not tailored for saddles, making it difficult for individuals with special needs to lift and secure a heavy western saddle onto a horse, requiring significant strength and coordination.
Innovation Solution
A lift system with a movable track and block and tackle system featuring hooks that release tension upon saddling, allowing self-installation of the saddle with minimal assistance, accommodating various saddle sizes and weights, and enabling incremental lifting and automatic hook release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a heavy western saddle (45-50 pounds) is lifted onto a horse using conventional methods, then the saddle can be installed, but the process requires significant strength and coordination that makes it challenging for individuals with special needs
Solution Approach 1:
A mechanical lift system acts as an intermediary device between the saddle and the individual with special needs. The system includes a track mounted above the horse, a carriage that moves along the track, and a block and tackle mechanism with hooks that attach to the saddle. This intermediary mechanical system performs the heavy lifting action, allowing the individual to control the process with minimal physical effort by operating the block and tackle with a single rope.
Solution Approach 2:
The lift system enables self-service by allowing the individual with special needs to independently operate the block and tackle mechanism to lift and position the saddle. The automatic release hooks further enhance self-service capability by releasing the saddle automatically when it is properly positioned on the horse's back, eliminating the need for manual unhooking.
2Adaptability or versatility
If current lift mechanisms are used for saddles, then lifting capability is provided, but they are not specifically tailored for saddles and do not allow automatic release upon installation
Solution Approach 1:
The lift system is designed with universal adaptability to accommodate various saddle types and sizes through adjustable hooks that can attach to different saddle configurations. The block and tackle mechanism with a single rope operation provides a universal control interface that works regardless of saddle weight or dimensions, making the system versatile for different equine-assisted therapy scenarios.
Solution Approach 2:
The system incorporates dynamic elements including movable hooks that can engage and disengage from the saddle, and an automatic release mechanism that responds to the saddle's position on the horse. The carriage moves along the track to position the saddle accurately, and the block and tackle dynamically adjusts to the load as the saddle is lifted and positioned.
3Productivity
If manual saddle lifting is performed without mechanical assistance, then no complex equipment is needed, but the process is time-consuming and requires extensive physical effort
Solution Approach 1:
The manual mechanical effort previously required for saddle lifting is replaced with a mechanical advantage system. The block and tackle mechanism substitutes for direct human lifting by providing mechanical advantage through pulleys and ropes, allowing a single individual to lift 45-50 pound saddles with minimal force applied to the rope.
Solution Approach 2:
The saddle lifting process is segmented into distinct phases: approach phase (carriage moves to saddle), lifting phase (block and tackle raises saddle), positioning phase (saddle lowered onto horse), and release phase (automatic unhooking). This segmentation allows the system to optimize each phase separately and enables the individual to focus on one task at a time, improving overall efficiency.
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
Enables individuals with special needs to easily lift and secure a saddle onto a horse, promoting participation in equine-assisted therapy and other interactions, reducing the need for extensive physical effort and enhancing accessibility.
Implementation Method 1
The present invention provides a lift system with a block and tackle system that allows incremental lifting of a heavy object, such as a saddle, onto a horse
Implementation Method 2
The block and tackle system featuring hooks that release tension upon saddling
Implementation Method 3
Once the saddle is lowered onto the horse the inward tension of the hooks caused by the weight of the saddle is released allowing the hooks to be removed from the saddle
Implementation Method 4
the inward tension of the hooks caused by the weight of the saddle is released

AI summary
A lift system includes a block and tackle pulley system movable along a track and carrying first and second hooks at a common attachment axis. The first hook is attached at a front end of the saddle while the second hook is attached to the back end of the saddle. Once the saddle is lowered onto the horse the inward tension of the hooks caused by the weight of the saddle is released allowing the hooks to be removed from the saddle without human intervention. The lift system accommodates a range of saddle sizes and weights.
