Pneumatic Exercise Apparatus with Bidirectional Mobile Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing muscle and joint exercise apparatuses are cumbersome, difficult to transport, and limited in their ability to perform bidirectional or multidirectional movements, leading to overactivation of muscle fibers, strain on tendons and joints, and inaccessibility for individuals with joint or cardiac issues, as they often require sudden and constant efforts that can cause fatigue and injury.
Innovation Solution
A lightweight, compact exercise apparatus with a hollow body and a mobile member that can translate along a main axis, driven by motor-driven means for both translation and braking, featuring a hinge for rotational freedom and adjustable positioning, allowing for bidirectional or multidirectional movements and customizable exercise planes, enabling efficient muscle training without straining antagonist muscles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional weights and pulleys are used for muscle exercise, then muscle strengthening is achieved, but the apparatus becomes heavy and cumbersome
Solution Approach 1:
The patent replaces traditional mechanical weight systems with a pneumatic cylinder that generates exercise resistance through air pressure. The mobile member is actuated by the pneumatic cylinder rather than external weights, eliminating the need for heavy counterweights while maintaining muscle strengthening capability through controlled pneumatic resistance.
Solution Approach 2:
The patent uses a pneumatic cylinder to provide the resisting force for muscle exercise. The cylinder contains pressurized gas that creates resistance when the mobile member moves, replacing traditional mechanical weight systems with a pneumatic mechanism that is lightweight yet provides sufficient resistance for effective muscle training.
2Strength
If constant heavy weights are used for exercise, then muscle strength increases, but sudden efforts cause strain on tendons and joints
Solution Approach 1:
The patent employs a mobile member that can move dynamically along the main axis of the hollow body, allowing the exercise apparatus to adapt to the user's movement speed and range. The pneumatic cylinder provides variable resistance that adjusts during the exercise motion, preventing sudden jerks or constant heavy loads that strain tendons and joints while maintaining effective muscle engagement.
3Measurement precision
If unidirectional movement is used for exercise, then specific muscles are targeted, but antagonist muscles remain overactivated
Solution Approach 1:
The patent implements bidirectional movement of the mobile member along the main axis, alternating between concentric and eccentric muscle actions. The pneumatic cylinder can push and pull the mobile member in both directions, allowing the user to perform full-range exercises that systematically activate and relax antagonist muscle groups, preventing overactivation while maintaining precise targeting of specific muscles through controlled motion phases.

AI summary
An apparatus of muscle and/or joint exercise adapted to reeducation and/or physical conditioning of a body part of a user, including a hollow body;a mobile member translatable inside the body; a motor-driven means arranged on the bottom of the body and adapted for driving and decelerating in displacement the mobile member in both translatory directions; a cooperating means between the body and a frame, this cooperating means being arranged on the bottom of the body and including: at least one hinge of the body on the frame, the hinge providing at least at least one degree of rotational freedom for the body around an axis of rotation; and a removable means for installing and removing the body, the removable means being designed for removably installing the body on a base slidingly mounted in the frame.
