Adjustable Pulley Exercise Device With Spring Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exercise devices that utilize body weight for resistance often lack adjustability and versatility to accommodate various user sizes, positions, and exercises, limiting their effectiveness in performing both bilateral and unilateral exercises efficiently.
Innovation Solution
An exercise device featuring a system of pulleys and a two-ended line with handles and carabiners, where pulleys are fixed to a wall or rack, and a spring assembly is used to increase resistance, allowing for adjustable and customizable exercises by varying the attachment points and incorporating a bar for different exercises like pull-ups and push-ups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a simple body weight exercise device is used, then the device is easy to operate and requires minimal equipment, but the device lacks adjustability and versatility to accommodate various user sizes and exercise types
Solution Approach 1:
The exercise device is designed to perform multiple functions including bilateral exercises, unilateral exercises, and exercises for users of different sizes and abilities. The system uses a single overhead support structure with adjustable components that can accommodate various exercise types and user requirements, making one device serve multiple purposes
Solution Approach 2:
The device incorporates adjustable components such as movable carabiners, repositionable handles, and modifiable line configurations that allow users to dynamically change the exercise parameters during use. This enables the same basic structure to adapt to different exercise intensities, user sizes, and exercise types without requiring multiple fixed installations
2Adaptability or versatility
If fixed position pulleys are used, then the exercise device provides stable support and consistent resistance, but the device cannot be quickly adjusted to accommodate different user sizes and exercise types
Solution Approach 1:
The exercise system is divided into independent modular components including separate pulleys, handles, carabiners, and line segments. This segmentation allows individual components to be quickly adjusted or reconfigured without affecting the entire system, enabling rapid adaptation to different exercise requirements and user sizes
Solution Approach 2:
The device includes pre-positioned attachment points, multiple carabiner locations, and strategically placed handles that are prepared in advance. Users can quickly switch between exercise configurations by simply moving to pre-established attachment points rather than making custom adjustments, reducing setup time while maintaining adaptability
3Adaptability or versatility
If the device is designed for bilateral exercises only, then the structure can be simplified, but the device cannot perform unilateral exercises which require different configurations
Solution Approach 1:
The exercise device is specifically designed to accommodate both bilateral and unilateral exercises using the same basic structure. The overhead support with multiple pulleys and adjustable line configurations allows users to perform symmetric bilateral exercises as well as asymmetric unilateral exercises, eliminating the need for separate equipment for different exercise types
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 device provides a versatile and adjustable resistance system that accommodates different user sizes and exercises, enhancing the effectiveness of bilateral and unilateral workouts by increasing linear force through the use of pulleys and spring assemblies, allowing for a range of exercises with adjustable resistance.
Implementation Method 1
a first pulley, a second pulley, and a two ended line trained through the first and second pulley
Implementation Method 2
the pulley or pulleys may be attached to the fixed position by a spring assembly or other device to increase the linear force in the handles or bar

AI summary
An exercise or training device that includes a first pulley, a second pulley, and a two ended line trained through the first and second pulley, the line having a first end and a second end, the first end of the line affixed to a first handle for gripping, a second handle for gripping affixed to the line at a position between the first end and the second end of the line. The pulleys may be fixed in position to a wall or rack such that they are horizontally spaced apart. In some embodiments, the pulley or pulleys may be attached to the fixed position by a spring assembly or other device to increase the linear force in the handles or bar.
