Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices often fail to effectively target a broad spectrum of muscle groups and provide versatile resistance training, leading to limited workout variety and potential injury risks.
Innovation Solution
An exercise device featuring dual handle assemblies with integrated elastic bands and wheels, allowing for varied muscle engagement and resistance through adjustable tension and movement, including abdominal roll-outs and leg exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-type exercise device is used, then the device structure is simple, but the ability to target broad spectrum of muscle groups is limited
Solution Approach 1:
The exercise device is designed with dual handle assemblies that can perform multiple functions - targeting upper body muscles through handle movements, abdominals through rolling motions, and leg/hip muscles through various positions. This multi-functional design allows a single device to replace multiple specialized exercise equipment while maintaining structural simplicity through the shared elastic band resistance mechanism.
2Adaptability or versatility
If fixed resistance is used, then the device structure is simple, but workout variety is limited
Solution Approach 1:
The resistance mechanism transitions from fixed to dynamic through the use of elastic bands. The elastic bands provide variable resistance that changes based on the position and movement of the handles, allowing users to perform diverse exercises with different resistance profiles without adding mechanical complexity. The resistance adapts automatically to the exercise being performed.
3Strength
If high resistance is used, then muscle stimulation is effective, but injury risk increases
Solution Approach 1:
The resistance parameter is made adjustable and variable through the elastic band system. Users can modify the resistance level by changing the elastic band configuration or selection, allowing effective muscle stimulation at lower injury-risk levels. The elastic nature of the bands also provides progressive resistance that increases smoothly with movement, reducing sudden high-force injuries.

AI summary
An exercise device includes a first handle assembly and a second handle assembly, the first handle assembly including a first handle and the second handle assembly including a second handle. A first cylinder is retained within an inner diameter of the first handle and a second cylinder is retained within the inner diameter of the second cylinder. A first elastic band is attached to top portions of the first cylinder and the second cylinder, and a second elastic band attached to bottom portions of the first cylinder and the second cylinder. Each of the first and second elastic bands provides resistance when spreading the first handle assembly and the second handle assembly apart.
