Multi-Purpose Exercise Apparatus With Pivotable Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing weightlifting equipment requires numerous attachment bars and separate holders for various exercises, limiting versatility and convenience, as each bar is typically designed for specific muscle groups and exercises.
Innovation Solution
A multi-purpose exercise apparatus with a central hub and pivotable arms and gripping members, allowing for adjustable angular positions and functions, enabling use as a barbell holder, cable attachment, and multiple exercise configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple attachment bars and separate holders are used for different exercises, then exercise versatility is improved, but device complexity and space requirements increase
Solution Approach 1:
The attachment bar is designed with multiple gripping members (first and second gripping members) that can be positioned at different locations along the bar, allowing a single bar to perform multiple exercise functions. The bar can be used for various exercises including bench press, shoulder press, and rowing movements without requiring separate specialized bars for each exercise.
Solution Approach 2:
The invention combines the functions of multiple separate attachment bars and holders into a single integrated apparatus. The first and second gripping members are merged onto one bar, and the holder integrates storage and positioning capabilities, eliminating the need for multiple separate pieces of equipment.
2Reliability
If separate holders are used to store barbells, then barbell retention is improved, but device complexity increases
Solution Approach 1:
The holder is integrated with the attachment bar system, combining the bar storage function with the exercise equipment itself. The holder includes a receptacle that receives and secures the attachment bar when not in use, eliminating the need for separate barbell racks or storage devices.
3Ease of manufacture
If fixed-position gripping members are used, then manufacturing simplicity is improved, but adaptability for different exercises decreases
Solution Approach 1:
The gripping members are positioned at multiple locations along the attachment bar, allowing dynamic selection of grip positions based on the specific exercise being performed. This provides adjustability and versatility for different exercise types while maintaining a relatively simple fixed-structure design that is easier to manufacture than fully movable systems.

AI summary
A multi-purpose exercise apparatus having a central hub. The central hub has a central plane and a bar bell aperture configured to receive a portion of a bar bell. A first arm is pivotably coupled to the central hub so as to be rotatable about a first arm pivot axis between a plurality of selectable first arm angular positions. A first gripping member is pivotably coupled to the first arm so as to be rotatable about a first handle pivot axis between a plurality of selectable first gripping angular positions. A second arm is pivotably coupled to the central hub so as to be rotatable about a second arm pivot axis between a plurality of selectable second arm angular positions. A second gripping member is pivotably coupled to the second arm to be rotatable about a second handle pivot axis between a plurality of selectable second gripping angular positions.
