Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller-type exercise devices are limited to a single axis of motion, restricting the range of exercise and failing to effectively work out multiple muscle groups, particularly lacking side-to-side and circular motion.
Innovation Solution
An exercise device featuring a planar support surface with a rolling joint that allows 360° freedom of movement, incorporating a rolling ball and joint configuration to enable forward-and-backward, side-to-side, and circular motions, with a locking mechanism to restrict rotation for targeted muscle group exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional roller-type exercise device is used, then the device structure is simple, but the range of motion is limited to a single axis
Solution Approach 1:
The patent introduces a second axis of rotation by incorporating a rolling joint with a ball element that can rotate freely within a cup-shaped structure. This allows the device to move not only forward and backward along the primary axis but also side-to-side and in circular motions, effectively adding a dimensional degree of freedom to the exercise device.
Solution Approach 2:
The patent employs a dynamic rolling joint mechanism where a ball rolls within a cup-shaped structure, allowing the device to transition between different motion states. The ball can rotate freely within the cup, enabling the device to adapt its motion path dynamically during exercise, providing both linear and circular movement capabilities.
2Adaptability or versatility
If a roller-type exercise device with fixed axis is used, then the device structure is simple, but the ability to work out multiple muscle groups is limited
Solution Approach 1:
The patent creates a multi-functional exercise device by incorporating a universal joint mechanism. The rolling ball within the cup-shaped structure allows the device to perform multiple functions: forward rolling exercises, side-to-side rolling exercises, and circular rolling exercises, thereby targeting different muscle groups including abdominals, obliques, and back muscles with a single device.
3Adaptability or versatility
If a rolling joint with 360° freedom of movement is added, then the range of motion is expanded, but the device complexity increases
Solution Approach 1:
The patent utilizes spherical geometry by employing a ball element that rolls within a cup-shaped structure. The spherical ball naturally provides 360-degree freedom of rotation, allowing motion in all directions without requiring complex mechanical linkages or multiple articulated joints, thus achieving high versatility with relatively simple structure.

Function Achieved in This Case
The device provides a broader range of motion, allowing users to effectively work out multiple muscle groups, including the abs and back, by enabling 360° movement and adjustable restriction for specific exercises, enhancing the versatility and effectiveness of home-based workouts.
Implementation Method 1
a rolling joint including a joint wall extending from the second face of the support surface to define a cavity configured to receive a rolling ball which facilitates such motion of the exercise device
