Universal Gym With Floating Pulley and Modular Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment is limited in its ability to provide a wide variety of exercises in a small space, and often struggles to accommodate athletes of different sizes or those with special needs. Additionally, the resistance mechanisms in current systems can be inadequate, failing to provide optimal weight increments or allowing for multiple sources of resistance.
Innovation Solution
A versatile universal gym with a compact frame that incorporates a weight stack, cables, pulleys, and a floating pulley system. This system allows for a vast array of exercises by enabling the use of free weights, elastic bands, and adjustable resistance levels, while also accommodating different user sizes and needs through modular design and accessory receiving ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple purpose-built machines are deployed to provide a wide variety of exercises, then exercise versatility is improved, but floor space requirement increases
Solution Approach 1:
The patent implements a universal gym system where a single multi-functional machine can perform numerous different exercises through interchangeable components and adjustable mechanisms. The machine serves multiple purposes including but not limited to squats, bench press, and rowing exercises, eliminating the need for multiple separate machines and thereby reducing floor space requirements while maintaining exercise versatility
Solution Approach 2:
The gym machine is divided into modular segments including removable weight stacks, interchangeable exercise attachments, and adjustable components. This segmentation allows the same base machine to be reconfigured for different exercises by swapping or adjusting specific modules, providing high exercise variety from a compact single-machine design
2Ease of manufacture
If equipment is designed for average-sized athletes, then manufacturing cost is reduced, but adaptability to different body sizes decreases
Solution Approach 1:
The machine incorporates dynamic adjustment mechanisms including movable seats, adjustable handle positions, and variable resistance levels that can be modified during use. These dynamic features allow the equipment to adapt to athletes of different sizes and abilities without requiring multiple fixed-design machines, maintaining ease of manufacture through standardized components while achieving high adaptability
Solution Approach 2:
The equipment allows for parameter changes including weight stack selection, exercise angle adjustments, and resistance level modifications. By enabling users to change these parameters, the machine accommodates different body types and fitness levels while maintaining a standardized base design that is cost-effective to manufacture
3Device complexity
If a single weight stack is used for all exercises, then device complexity is reduced, but resistance optimization for different exercises becomes difficult
Solution Approach 1:
A single weight stack is designed to serve multiple exercises by incorporating a universal cable system with adjustable pulley positions and multiple attachment points. This universal resistance system can be configured for different exercises (squats, presses, rows) without requiring separate weight stacks, maintaining device simplicity while enabling exercise-specific resistance optimization through mechanical configuration rather than additional components
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
The universal gym provides a high-density exercise solution that can be used by athletes of varying sizes and abilities, offering a nearly infinite array of exercises in a remarkably small footprint. It allows for customizable resistance levels and multiple sources of resistance, enhancing user flexibility and workout variety.
Implementation Method 1
one or more cables routed about the frame via a plurality of pulleys selectively connecting the at least one weight stack to one or more exercise attachment points
Implementation Method 2
the resistance comprising at least one weight stack contained by the frame

AI summary
A universal gym exhibits improved versatility employing a frame supporting a weight stack connected via cable to an exercise attachment point, which further engages a floating pulley with an extension cable. Accessory receiving ports throughout the frame allow placement of the floating pulley virtually anywhere the athlete desires, affording a vast array of exercises employing the weight stack. Free weights, elastic bands, and the weight stack, alone or in combination, can provide a diverse resistance. Decorative panels, optionally mounted with hollow-headed bolts each having an axial recess for receiving and retaining a panel-mounting rivet, can disguise the universal gym when not in use.
