Adjustable Low Pulley for Seated Back Exercise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for exercise equipment that allows users to perform back exercises by pulling weights with their arms while seated, as most existing equipment is costly and space-consuming, and there is a high demand for equipment that provides deep stimulation to various body parts and allows one- or two-armed movements.
Innovation Solution
An adjustable low pulley with a support frame, seating unit, weight unit, external force transmission unit, and pulley unit that enables users to pull weights with their arms while seated, allowing for smooth force direction change and minimizing friction, enabling diverse exercise variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional exercise equipment is used, then exercise functionality is provided, but the equipment occupies large space and is costly
Solution Approach 1:
The patent combines the low pulley mechanism with a seated exercise configuration, merging multiple functional elements (support frame, seating unit, weight unit, external force transmission unit, and pulley unit) into a single integrated structure that provides back exercise functionality while occupying minimal space
Solution Approach 2:
The equipment is designed to provide multiple exercise variations through adjustable configurations, allowing users to perform different back exercises by modifying arm movement positions and weights, thereby achieving versatility from a compact device
2Adaptability or versatility
If traditional exercise equipment is used, then exercise functionality is provided, but waiting time increases when many people are present
Solution Approach 1:
The equipment is designed as a compact, self-contained unit that can be easily positioned in limited spaces within a gym, allowing multiple users to access different exercise stations simultaneously and reducing waiting time for desired equipment
3Reliability
If the pulley system is designed for force transmission, then weight lifting stability is improved, but friction between cable and components increases
Solution Approach 1:
The pulley unit acts as an intermediary component between the cable and the weight unit, mediating the force transmission while minimizing direct friction between the cable and other components through proper pulley design and cable routing
4Adaptability or versatility
If the pulley unit changes force direction, then exercise versatility is improved, but the movement path of the cable becomes complex
Solution Approach 1:
The pulley unit introduces dimensional changes in the cable path by routing the cable through multiple pulleys at different positions and angles, enabling force direction changes that provide diverse exercise variations while maintaining a manageable cable configuration
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 pulley system allows for stable weight lifting with reduced friction, enabling exercises that activate multiple muscle groups, including the trapezius, latissimus dorsi, and erector spinae muscles, and provides flexibility in exercise form through arm movements.
Implementation Method 1
a pulley unit for causing the direction of the force applied to the external force application unit to switch to a vertical direction while defining a movement path of the cable
Implementation Method 2
a cable mediating the external force application unit and weight unit

AI summary
An adjustable low pulley according to an embodiment of this invention is an equipment that can be used to perform exercises by pulling a weight with an arm while being seated, which connects a support frame standing in an upright position while being supported on the floor, a seating unit connected to the front of the support frame to provide a space for seating, and the support frame, it is connected to a weight unit composed of multiple block weights and to the above weight unit. It includes an external force transmission unit for transmitting an external force to allow the weight to move up and down by the applied external force while the seated user grips it.
