VARRI Anti-Gravity Vertical Running Machine for Joint Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively remove the gravitational impact on joints and bones during running, leading to repetitive stress injuries and limitations in rehabilitation for individuals with physical restrictions or injuries.
Innovation Solution
The VARRI (Vertical, Anti-Gravity, Rehabilitation, Impact Resistant) device uses a mechanical platform with interconnected tubes, pulleys, and a programmable computer to simulate running while eliminating gravitational effects, allowing for non-impact training and rehabilitation by replicating muscle loads without joint stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional running is performed on ground surface, then muscle strength and cardiovascular fitness are improved, but repetitive impact causes joint and bone damage
Solution Approach 1:
The device employs an anti-gravity mechanism that counteracts the user's body weight through a mechanical system involving a movable platform, cables, and counterweights. This eliminates the impact forces on joints and bones while preserving the muscle engagement required for running training, directly resolving the contradiction between strength improvement and impact reduction
2Object-affected harmful factors
If gravitational forces are eliminated during running, then joint and bone stress is reduced, but muscle loading may be insufficient for effective training
Solution Approach 1:
The device applies local quality by selectively eliminating gravitational forces only at the contact points (feet and platform interface) while maintaining gravitational loading on the muscle groups being trained. The cable and pulley system is configured to remove impact forces transmitted through the skeletal system while preserving resistive forces that engage the hip flexors, extensors, and lower extremity muscles
3Productivity
If vertical running motion is simulated, then running-specific muscle activation is achieved, but gravitational deviation causes instability
Solution Approach 1:
The device creates an equipotential environment by orienting the user horizontally and eliminating gravitational variation during the running motion. The movable platform moves parallel to the ground surface, ensuring that gravitational force remains constant and perpendicular to the direction of motion throughout the entire running cycle, thereby maintaining body stability while enabling vertical running mechanics
