Adjustable Exercise Device With Telescopic Supports And Deployable Stabilizers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pull-up devices are often bulky, expensive, and not easily adaptable to individual users' needs, leading to injuries and limited exercise options due to inadequate anchoring, durability, and lack of adjustability, making them unsuitable for home use and travel.
Innovation Solution
An adjustable exercise device with heavy-duty square tubing, telescopic upper and central posts, and deployable lateral leg supports for stability, along with selectively attachable handgrips to accommodate various exercises and user sizes, providing a sturdy and versatile fitness solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pull-up bar is used for upper-body exercises, then muscle development is promoted, but serious injury can result when the user is not properly trained
Solution Approach 1:
The device allows dynamic adjustment of the bar height and angle to match the user's current ability level. The bar can be positioned at multiple heights and tilted at different angles, enabling users to progress from assisted to full pull-ups as their strength increases, thereby reducing injury risk while maintaining exercise effectiveness
Solution Approach 2:
The device enables changing key parameters such as bar height, tilt angle, and support position to adapt the exercise difficulty to the user's training level. This allows novice users to perform modified pull-ups with reduced bodyweight support, while advanced users can achieve full pull-ups, thus preventing injuries from improper form
2Ease of operation
If door frame pull-up devices are used, then home exercise is enabled, but the device collapses from the door frame causing injury and property damage
Solution Approach 1:
Instead of relying on door frames, the device creates a self-contained stable base on the floor. The base unit with wide footprint and non-slip feet replicates the stability function of a door frame without the risk of collapsing, allowing safe home exercise independent of door frame anchoring
Solution Approach 2:
The device transitions from vertical anchoring (door frame) to horizontal stabilization (floor-based wide base). By distributing weight across a large horizontal footprint with strategic foot placement, the device achieves stability in a different dimensional approach, eliminating the collapse risk associated with vertical door frame anchoring
3Reliability
If door frame pull-up devices are positioned over the top of the door frame, then the device is anchored, but the user is unable to perform modified pull-up with less than all bodyweight lifted
Solution Approach 1:
The bar height and angle are dynamically adjustable to accommodate different exercise variations. Users can position the bar at heights that allow assisted pull-ups, neutral grip positions, and progressive strength building exercises, enabling a full range of modified pull-up regimens while maintaining device stability
Solution Approach 2:
The device serves multiple exercise functions beyond traditional pull-ups. The adjustable bar can be used for assisted pull-ups, negative pull-ups, hangs, and various grip variations, making it a universal fitness tool that adapts to different skill levels and training goals while maintaining reliable floor-based anchoring
4Ease of operation
If pull-up devices are made portable for home and travel use, then accessibility is improved, but the devices become bulky and heavy
Solution Approach 1:
The device is divided into separable components including the base unit, bar assembly, and adjustment mechanisms. This segmentation allows users to disassemble and transport only essential parts, reducing the weight burden during travel while maintaining full functionality when assembled at the destination
Solution Approach 2:
The bar assembly and adjustment components are designed to nest within or attach compactly to the base unit. When not in use, the bar can be stored within the base or folded against it, creating a compact package that minimizes transport weight and space requirements while preserving the complete device functionality
5Weight of moving object
If pull-up devices are made compact for portability, then weight is reduced, but the exercise range and stability are limited
Solution Approach 1:
The compact device incorporates dynamic adjustment mechanisms that allow the bar height and angle to be changed without adding significant weight. Telescopic or foldable components enable multiple exercise configurations within a compact form factor, maintaining exercise range while minimizing transport weight
Solution Approach 2:
The compact device is designed to perform multiple exercise functions despite its reduced size. The adjustable bar supports various grip positions, assisted pull-ups, and different exercise variations, ensuring comprehensive workout capability in a lightweight, portable package that does not sacrifice exercise versatility

AI summary
An exercise device, having a pair of supports that rest upon a ground surface and a bridge that extends between the supports and is elevated above the ground surface. The supports each include an upper support that includes an upper tube and a lower support that includes a central post that together telescope so as to adjust the height of the bridge. Handgrips are selectively attachable to the bridge for allowing the user to perform various exercises. Attachment plates secure each end of the bridge to one of the upper tubes. The lower supports are each T-shaped, including a base member and each have a pair of lateral supports that are deployable to stabilize the base members from side movement.
