Variable-Load Exercise Equipment With Cable-Position Resistance Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise equipment requires cumbersome processes to change the load for muscular workouts, limiting flexibility in adjusting exercise intensity based on user's physical condition or exercise amount.
Innovation Solution
A variable load module that connects a rotating bar and load application portion, allowing the position of cable connection to vary, enabling easy adjustment of exercise load intensity by changing the distance between the grip and the cable, while maintaining the same number of weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of weights is changed to adjust exercise load, then the exercise intensity can be modified, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent changes the parameter of cable connection position on the rotating bar to adjust exercise load. By moving the cable connection along the rotating bar's length, the load is varied without changing the number of weights, making adjustment quick and easy while maintaining adaptability.
Solution Approach 2:
The cable acts as an intermediary between the weights and the rotating bar. By changing where the cable connects to the rotating bar, the mechanical advantage changes, allowing load adjustment without directly moving the weights themselves.
2Force
If weights are used to apply load, then sufficient resistance can be provided, but the weights cannot be subdivided and require cumbersome changing processes
Solution Approach 1:
Instead of changing the mass of weights, the patent changes the geometric parameter of cable connection position. This provides fine-grained load adjustment capability without needing subdivided weights or complex weight changing mechanisms.
Solution Approach 2:
The system transitions from static weight configuration to dynamic cable position adjustment. The cable connection can be moved along the rotating bar to continuously vary the load, making the system more dynamic and flexible.
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 easy and flexible adjustment of exercise load intensity, expanding user options and enhancing compatibility with existing equipment.
Implementation Method 1
a load application portion disposed at the rear of the seating portion, including a plurality of weights, and connected to the rotating bar with a cable to be raised and lowered according to the rotation of the rotating bar
Implementation Method 2
When the distance from the grip portion increases, the position moving portion may lengthen the vector path of a first external force applied to the grip portion to raise and lower the load application portion, thereby increasing the intensity of the first external force

AI summary
An exercise equipment with a variable load module includes a seating portion providing a space for a user to sit; an external force application portion disposed adjacent to the seating portion and including the rotating bar that rotates about a main rotating axis and a grip portion that is formed on the rotating bar and provides a space for a user to grip; a load application portion disposed at the rear of the seating portion, including a plurality of weights, and connected to the rotating bar with a cable to be raised and lowered according to the rotation of the rotating bar; and a variable load module connecting the rotating bar and the load application portion and allowing the position at which the cable is connected to the rotating bar to vary so that the load applied to the rotating bar changes.
