Adjustable Body Weight Exercise Rack with Multi-Axis Bar Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body weight exercise devices lack variability in the types and ways exercises can be performed, restricting users to limited variations of exercises and requiring multiple devices for greater flexibility, which is costly and space-prohibitive for home use and inconvenient for public spaces.
Innovation Solution
A fully adjustable body weight exercise device with two opposing horizontal bars that can be adjusted up and down along vertical uprights, and the uprights adjusted side to side along a base, allowing for virtually unlimited variations of exercises like pull-ups, push-ups, dips, rows, squats, and leg raises by changing bar positions and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent body weight exercise devices are used to increase exercise variability, then exercise variety is improved, but cost and storage space requirements increase
Solution Approach 1:
The patent combines multiple independent exercise stations (pull-up bar, push-up station, dip station, row station) into a single integrated structure. The horizontal and vertical bars are arranged to simultaneously support pull-ups, push-ups, dips, and rows, allowing users to perform all these exercises on one device rather than requiring separate stations for each exercise type.
Solution Approach 2:
The exercise device is designed with universal functionality to support multiple exercise types through a single structure. The adjustable horizontal bars and vertical uprights can be configured to provide pull-up bars, push-up surfaces, dip stations, and row supports, making one device serve the purpose of multiple specialized devices.
2Adaptability or versatility
If multiple exercise devices are purchased for home use, then exercise variety is improved, but storage space requirements increase
Solution Approach 1:
The patent merges multiple exercise functions into a single compact structure that can be stored in limited space. By integrating the pull-up bar, push-up station, dip station, and row station into one unified device, the patent eliminates the need to store multiple separate pieces of equipment, significantly reducing storage space requirements while maintaining exercise variety.
3Device complexity
If fixed-position exercise towers are used, then device simplicity is improved, but exercise variability is reduced
Solution Approach 1:
The patent introduces dynamic adjustability to the exercise device through movable horizontal bars that can be repositioned along the vertical uprights. This allows the device to transition between fixed and adjustable configurations, providing both structural simplicity and exercise variability. Users can adjust the bar positions to create different exercise variations while maintaining a straightforward device design.
Solution Approach 2:
The patent enables exercise variability by allowing changes in the positional parameters of the horizontal bars along the vertical uprights. By adjusting these parameters, users can modify the height, angle, and orientation of the bars to create different exercise variations (pull-ups, push-ups, dips, rows) without changing the basic device structure, thus maintaining simplicity while increasing versatility.
4Ease of operation
If public park exercise equipment is used, then accessibility is improved, but weather and crowd exposure increase
Solution Approach 1:
The patent designs a self-contained exercise device that does not require external structures like ceilings, walls, or doorways for mounting. The device stands independently on the ground, making it suitable for indoor use in homes, gyms, or offices while also being portable enough for outdoor use. This self-service design eliminates the need to attach to existing structures, providing flexibility in placement and protection from weather and crowds.

AI summary
One embodiment of a steel adjustable body weight exercise rack consists of a left and right pair of vertical uprights that are attached opposite one another along a base consisting of two parallel base tubes. A lower and upper pair of horizontal bars are attached across each pair of vertical uprights. The horizontal bars adjust up-and-down along the vertical uprights, and the vertical uprights adjust side-to-side along the base tubes. Three dimensional adjustments to the improved body weight exercise device allow the user to manipulate their body with and across the horizontal bars to perform virtually unlimited variations of body weight exercises.
