Sliding Grip Exercise Device with Adjustable Spring Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices, such as pull-up bars, often neglect triceps in push motions and lower back in extension exercises, and lack adjustable resistance to work multiple muscle groups effectively, requiring users to purchase multiple devices to achieve diverse workouts.
Innovation Solution
A sliding grip resistance exercise device with rubber pegs for wall and floor support, featuring springs with rotatable spring caps for adjustable resistance, allowing for medial and lateral pull-ups, lower back extension, and sit-up assistance exercises, and adjustable resistance via knobs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single pull-up bar is used, then the device is simple and cost-effective, but it cannot provide diverse exercise functions for multiple muscle groups
Solution Approach 1:
The pull-up bar is designed with sliding hand grips that can be positioned at multiple locations along the bar, enabling a single device to perform multiple exercise functions including pull-ups, push-ups, and lower back extensions. The spring mechanism provides adjustable resistance for different muscle groups, making one device replace multiple specialized equipment.
Solution Approach 2:
The hand grips are designed to slide along the bar rather than being fixed, allowing dynamic repositioning during exercises. The spring-loaded mechanism enables variable resistance adjustment, and the foot rest can be positioned at different angles, providing adaptability for various exercise types and intensity levels.
2Force
If fixed hand grips are used on pull-up bars, then the device structure is simple, but it cannot provide adjustable resistance for working different muscle groups
Solution Approach 1:
The spring mechanism allows resistance parameters to be changed by adjusting the compression of springs through the sliding hand grips. Users can modify the resistance level by moving grips to different positions on the bar, enabling customized force application for targeting specific muscle groups such as biceps, triceps, and lower back.
3Adaptability or versatility
If vertical resistance only is provided by pull-up bars, then the device is simple to manufacture, but it cannot provide horizontal resistance for diverse muscle engagement
Solution Approach 1:
The device incorporates horizontal resistance capability through the sliding hand grip mechanism that moves along the horizontal bar, in addition to the traditional vertical pull-up motion. This adds a dimensional aspect to the resistance application, enabling exercises that engage different muscle groups through lateral and diagonal movements.
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
Enables a versatile workout that engages more muscle groups by providing adjustable resistance and support for various exercises, including medial and lateral pull-ups, lower back extension, and sit-up assistance, using a single device.
Implementation Method 1
The cavity of ventral bar supporting handgrips will have two springs, one spring for each respected handgrip
Implementation Method 2
one spring cap will have a protuberance attached to it. The protuberance will allow one spring cap to rotate and compress springs when engaged with handgrips appendage
Implementation Method 3
Disclosed fitness device will have at least six rubber pegs attached to its frame, rubber pegs will be utilized for wall and floor support

AI summary
A multi-functional sliding grip exercise device, specifically but not limited to: sliding grip medial pull-ups, sliding grip lateral pull-ups, lower back extension/sit-up assistance exercise. Exercise device will have rotatable rubber pegs attached to horizontal bars to aid in utility. Horizontal bars supporting hand grips will have apertures on its frame; apertures will take on the form of a âTâ with arms going vertically down to engage device locking system. Horizontal bar with apertures will have tracks on top surface and bottom surface to support guidance of Hand grips. Horizontal bar with apertures will have a resistance element housed within, preferably but not limited to springs; also housed within bar will be spring caps with an protuberance attached that will make contact with Handgrips appendage to engage springs. Handgrips may have indentations to support lower back bar for lower back extension/sit-up assistance exercise. Device may have adjustable resistance.
