Interchangeable Fitness Apparatus with Segmented Rolling Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing core workout appliances are typically designed for specific exercises, leading to the need for multiple devices in gyms and home studios, which is inconvenient and takes up space.
Innovation Solution
A multi-functional exercise apparatus with an elongate bar and a rolling member that can be interchanged to function as a push-up bar, plank bar, abdominal wheel, and mace-like fitness club, allowing for various exercises and increased functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple core workout appliances are provided for different exercises, then exercise versatility is improved, but device complexity and space requirements increase
Solution Approach 1:
The apparatus employs a universal bar structure with multiple aperture positions that can accommodate different rolling members (ab wheel, push-up bar, plank bar, mace). This single apparatus design allows users to perform multiple exercises including ab rollouts, push-ups, planks, and mace swings, replacing the need for separate dedicated equipment for each exercise type.
Solution Approach 2:
The apparatus is divided into separable components: a standardized bar with apertures and interchangeable rolling members. Each rolling member can be independently attached or detached by inserting or removing through the bar, allowing users to segment and reconfigure the apparatus based on exercise requirements without dealing with a complex integrated system.
2Adaptability or versatility
If multiple core workout appliances are provided for different exercises, then exercise versatility is improved, but space requirements increase
Solution Approach 1:
The universal bar design consolidates multiple exercise functions into a single apparatus footprint. Users can perform ab rollouts, push-ups, planks, and mace exercises all with one piece of equipment, significantly reducing the space required compared to having separate dedicated equipment for each exercise type.
Solution Approach 2:
The apparatus merges multiple previously separate exercise tools (ab wheel, push-up bar, plank bar, mace) into a single combined unit. The bar serves as a common platform for all rolling members, consolidating their functions and eliminating the need for multiple separate pieces of equipment occupying different spaces.
3Area of stationary object
If a single multi-functional apparatus is provided, then space requirements are reduced, but device complexity increases
Solution Approach 1:
The multi-functional apparatus is segmented into simple, independent components: a bar with standardized apertures and separate rolling members. This segmentation allows each component to remain structurally simple while the system as a whole provides multiple functions, avoiding the complexity that would arise from integrating all functions into a single monolithic structure.
Solution Approach 2:
The apparatus employs a dynamic, reconfigurable design where the bar can be quickly transformed between different exercise configurations by simply moving or swapping rolling members through the apertures. This dynamic adaptability provides multi-functionality without requiring complex mechanical systems, as the reconfiguration is achieved through simple insertion and removal actions.

AI summary
An exercise apparatus is disclosed. The exercise apparatus includes an elongate bar, a rolling member including an outer surface and a centrally-located axial aperture that extends through the rolling member, and at least one pair of apertures disposed within the elongate bar, each aperture of the pair of apertures being configured to receive a locking pin. A distance between the at least one pair of apertures is slightly greater than a length of the centrally-located axial aperture, and at least one pair of apertures is disposed entirely on a right or left side of a midpoint of the elongate bar.
