Multi-Directional Roller Exercise Base for Quiet 360-Degree Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller-type exercise devices are limited to a single axis of motion, lack side-to-side capability, and often produce noise due to elaborate structural features, making them less effective and noisy.
Innovation Solution
An exercise device with a base and bearing assemblies that allow for 360-degree motion, incorporating bearing axles and rollers that rotate smoothly and quietly over the base, facilitated by a brake mechanism for controlled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional roller-type exercise devices use elaborate structural features to facilitate rolling, then the device can roll forward and backward, but the device produces undesirable loud noise during use
Solution Approach 1:
The patent replaces traditional mechanical rolling structures with a magnetic field-based system. Magnets embedded in the roller interact with a magnetic track, enabling rolling motion without mechanical contact between moving parts, thereby eliminating noise while maintaining rolling capability
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the roller and the track. This magnetic field mediates the interaction, allowing the roller to move along the track without direct mechanical contact, thus reducing noise while preserving the rolling function
2Ease of manufacture
If conventional roller-type exercise devices are designed with simple rolling structures, then the device is easy to manufacture, but the device is limited to a single axis of motion and cannot roll side-to-side
Solution Approach 1:
The patent employs a dynamic magnetic field configuration that allows the roller to respond to forces in multiple directions. The magnetic interaction enables the roller to dynamically adjust its motion path, facilitating both forward-backward and side-to-side rolling movements while maintaining a simple overall structure
Solution Approach 2:
The magnetic rolling mechanism serves multiple functions: it enables forward-backward rolling, side-to-side rolling, and provides smooth quiet operation. This single magnetic-based system replaces what would traditionally require multiple separate mechanical mechanisms, achieving versatility without increasing manufacturing complexity

AI summary
A rolling-type exercise device includes a base having a central opening formed therein. A plurality of bearing assemblies are operatively coupled to the base. Each bearing assembly includes a pair of bearing supports and a bearing axle extending between the pair of bearing supports and being coupled to the pair of bearing supports so as to facilitate rotation of the bearing axle relative to the base. A roller operatively interfaces each bearing axle of the plurality of bearing assemblies and at least partially protruding through the central opening, the roller being configured to rotate relative to the base within the central opening.
