Vibration Pulley System for Adjustable Exercise Intensity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitness equipment with vibration therapy systems lack adjustable vibration intensity, which limits user customization and effectiveness in strength training exercises.
Innovation Solution
An exercise apparatus incorporating a vibration pulley system with a toothed pulley and contact roller, where the pulley cable is threaded through a toothed pulley and connected to a handle, allowing for adjustable vibration intensity by varying the engagement between the toothed pulley and contact roller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed vibration system is used, then the structure is simple, but the vibration intensity cannot be adjusted
Solution Approach 1:
The patent applies the dynamics principle by making the pulley system adjustable rather than fixed. The toothed pulley can be repositioned along the cable path, and the cable tension can be modified, allowing the vibration intensity to be dynamically changed during exercise. This transforms a static structure into a dynamic one that adapts to different user needs and exercise requirements.
Solution Approach 2:
The patent implements parameter changes by allowing modification of key physical parameters in the pulley system - specifically the cable tension and pulley position. By changing these parameters, the vibration characteristics (frequency and amplitude) can be adjusted without fundamentally redesigning the entire system, thus achieving adaptability while controlling complexity.
2Adaptability or versatility
If vibration therapy is added to exercise equipment, then user benefits are enhanced, but the equipment complexity increases
Solution Approach 1:
The patent merges the vibration therapy function with the existing exercise resistance mechanism by integrating a toothed pulley into the cable system. Instead of adding a separate vibration device, the vibration function is combined with the resistance training mechanism, allowing both functions to work through a unified structure that reduces overall equipment complexity.
Solution Approach 2:
The pulley system serves multiple functions simultaneously - it provides both exercise resistance and vibration therapy. The same cable and pulley mechanism that creates resistance during exercise also generates therapeutic vibrations when the toothed pulley engages with the cable, eliminating the need for separate dedicated components for each function.

AI summary
In an exercise apparatus incorporating a vibration pulley system, a vibration unit connected to the frame of the exercise apparatus. The vibration unit may include a toothed pulley and a contact roller mounted on a bracket. A pulley cable may include an end fixedly secured to the frame of the exercise apparatus. The pulley cable may be threaded about the toothed pulley and the opposite end of the pulley cable connected to a handle that may be grasped by an operator. The toothed pulley may be in engagement with the contact roller to generate vibrations that may be felt by the operator. The vibration intensity may be adjusted to variable levels.
