Solution Overview
Problem
Existing exercise devices lack versatility and effectiveness in providing comprehensive workouts for various body parts, particularly in engaging core and stabilizer muscles through balanced movements and dynamic translations.
Innovation Solution
An exercise device comprising a platform with handles and a rotating roller that translates in different directions based on the roller's rotation, allowing for dynamic movements and balance adjustments to engage core and stabilizer muscles, including features like tilting and adjustable surface sections for diverse exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple roller design is used, then device complexity is reduced, but muscle engagement effectiveness deteriorates
Solution Approach 1:
The platform is designed to dynamically tilt and translate in response to user movements and roller rotation. The platform includes a tilting mechanism that allows it to rotate about a transverse axis, and the roller is configured to rotate about a longitudinal axis. This dynamic coupling between roller rotation and platform tilting creates adaptive resistance that engages core and stabilizer muscles effectively without requiring complex external control systems.
Solution Approach 2:
The device uses the user's own body weight and movements to generate the exercise resistance. As the user moves on the platform or applies force through the handles, the roller rotates and the platform tilts accordingly, creating self-adjusting resistance patterns. The system automatically adapts to user actions without requiring external power sources or complex control mechanisms.
2Manufacturing precision
If a fixed platform design is used, then manufacturing precision is improved, but workout versatility deteriorates
Solution Approach 1:
The platform transitions from a fixed design to a dynamic one that can tilt and translate. The tilting mechanism allows the platform to rotate about a transverse axis, and the roller rotation about a longitudinal axis creates coupled movements. This dynamic capability enables multiple exercise modes and body positions while maintaining straightforward manufacturing through well-defined mechanical joints and axes.
3Device complexity
If the roller is fixed in position, then device complexity is reduced, but core muscle engagement deteriorates
Solution Approach 1:
The platform is coupled to the roller such that roller rotation about a longitudinal axis causes the platform to tilt about a transverse axis. This dynamic coupling means the platform position and orientation change in response to roller rotation, creating unstable support that requires continuous core muscle activation for balance. The system achieves this with simple mechanical coupling rather than complex active control systems.
Solution Approach 2:
The tilting platform creates a counterbalancing effect where the user's center of gravity must be continuously adjusted to maintain equilibrium. As the roller rotates and the platform tilts, the user's body position relative to the support point changes, requiring opposing muscle actions to prevent falling and maintain proper exercise form. This passive instability provides effective core engagement without requiring active stabilization mechanisms.

AI summary
Disclosed is an exercise device having a platform and a roller. The platform has a surface sized and shaped to support a body part of a user and a pair of handles. The roller is coupled to the platform and configured to rotate relative to the platform. The platform is configured to translate in a first direction when the roller rotates in a first direction of rotation and translate in a second direction when the roller rotates in a second direction of rotation.
