Dynamic Motion Exercise Machine With Sliding Rotating Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strength conditioning exercise machines fail to dynamically move the user's center of mass relative to the user engagement means during exercise, which limits their ability to simulate natural human motion and everyday activities effectively.
Innovation Solution
A movable user engagement member is operatively linked to a movable user support that slides while rotating, allowing the user's center of mass to move dynamically relative to the user engagement member, creating a more natural and effective exercise motion by concurrently sliding and pivoting the user support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stationary user support is used in strength conditioning machines, then the machine structure is simple and stable, but the user's center of mass cannot move dynamically during exercise, reducing the simulation of natural human motion
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a stationary user support to a movable user support that can slide and rotate during exercise. The user support is connected to a moving member that travels along guide surfaces, allowing the support to dynamically adjust its position and orientation. This dynamic configuration enables the user's center of mass to move naturally during exercise, simulating real-world motions while maintaining structural integrity through the guided movement mechanism.
2Adaptability or versatility
If a movable user support is implemented to dynamically move the user's center of mass, then the simulation of real-world activities is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a moving member that simultaneously performs multiple functions: it supports the user, enables dynamic positioning, and guides the movement along predetermined paths. The same mechanism that moves the user support also controls the sliding and rotating motions, eliminating the need for separate complex systems. This multi-functional approach achieves superior biomechanical positioning while minimizing overall device complexity.
3Ease of operation
If the user support slides while rotating during exercise, then muscle engagement is improved through optimal biomechanical positioning, but the mechanism complexity increases
Solution Approach 1:
The patent applies spheroidality by using rotational motion of the user support around a pivot point to achieve natural arc-like movement paths. The moving member rotates about a pivot connection, creating curved trajectories that match natural human motion patterns. This curved motion approach improves muscle engagement by following biomechanically optimal paths while simplifying the mechanism compared to complex multi-axis positioning systems.

AI summary
A series of improved exercise machines with a movable user engagement member operatively linked to a sliding while rotating user support such that when the user engagement member is engaged and activated by the user the user engagement member concurrently causes movement of the operative linkage system, which concurrently causes the user support to slide while rotating. This creates dynamic motion of the user support relative to the user engagement member.
