Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise systems for the oblique muscle group are inefficient in adjusting force levels, leading to user fatigue and increased chances of error when changing settings.
Innovation Solution
A wheel-based exercise system with an outer and inner wheel portion at different radial distances, a weight system with multiple elements and a selection mechanism, and a coupling mechanism using a cable, pulley, and quick detach pin, allowing users to comfortably grip and turn the wheels in varying directions to adjust the force applied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single wheel mechanism is used with fixed weight, then the structure is simple, but the adaptability for different exercise intensities is poor
Solution Approach 1:
The wheel mechanism is divided into two distinct portions: an outer wheel portion and an inner wheel portion. Each portion can be independently grasped and rotated, allowing users to select different exercise modes and intensities. This segmentation provides adaptability for different exercise needs while maintaining a relatively compact structure.
Solution Approach 2:
The dual-wheel design enables the single apparatus to serve multiple functions: users can exercise by gripping only the outer wheel, only the inner wheel, or both wheels simultaneously. This multi-functionality increases adaptability for different exercise intensities and muscle engagement levels without requiring separate exercise equipment.
2Adaptability or versatility
If frequent adjustment of force is allowed, then the adaptability is improved, but the ease of operation deteriorates due to user fatigue and error
Solution Approach 1:
The system allows dynamic adjustment of exercise intensity by enabling users to freely combine or separate the use of inner and outer wheel portions. Users can start with one wheel and progressively incorporate the other wheel as strength improves, providing continuous adaptability without requiring complex mechanical adjustments or frequent interruptions.
3Adaptability or versatility
If multiple weight elements are provided for selection, then the adaptability for different force levels is improved, but the device complexity increases
Solution Approach 1:
Instead of adding multiple weight elements in a single dimension, the invention creates a new dimension of resistance adjustment by utilizing two concentric wheel portions at different radii. The resistance variation is achieved through the dimensional difference in rotational radius rather than through multiple discrete weight elements, thereby providing force level selection without proportionally increasing structural complexity.

AI summary
An exercise system for exercising a body's oblique muscle group relies upon a wheel mechanism having an outer wheel portion arranged at a first radial distance and an inner wheel portion arranged at a second radial distance, where the outer and inner wheel parts include respective sets of handgrips. A weight system is arranged to be coupled to and decoupled from the wheel mechanism. A coupling mechanism couples the weight system to and decouples the weight system from the wheel mechanism, in a first circumferential direction, or in a second circumferential direction. The hand grips allow a user to grasp the wheel mechanism and turn it in the first or the second circumferential directions against a respective force that the wheel mechanism is turned against that is defined by the aggregate selected weight when coupled to the wheel mechanism, in one of the first and second circumferential directions.
