Gripedo Exercise Device Wrenching Motion and Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment, such as wrist rollers, lack versatility and do not allow for a wide range of exercises, including wrenching-like movements, supination, pronation, and rotations, which limits their effectiveness in targeting upper extremity muscles like wrists, forearms, and shoulders, and does not provide flexibility for use without a frame or structure.
Innovation Solution
The Gripedo device, a portable and multifunctional exercise device with a ball handle and shaft that allows for wrenching-like motions, supination, and pronation, and can be used with existing frames or structures, as well as with sand or weights, enabling exercises like wrist extensions, flexions, and rotations, and can be adapted for various activities like pull-ups, deadlifts, and therapeutic exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wrist rollers are mounted on existing frames or structures, then they can provide resistance for wrist flexion and extension, but they do not allow wrenching exercises or supination pronation movements
Solution Approach 1:
The Gripedo device is designed to perform multiple functions: it can be used for wrist flexion and extension when mounted on frames, and for wrenching exercises, supination pronation, and rotations when used with sand or weights. This multi-functionality resolves the contradiction by enabling a wide range of exercises without requiring different specialized devices for each exercise type.
2Force
If weights are attached to wrist rollers, then resistance is increased for twisting motions, but the device cannot be used for exercises without mounting on a frame
Solution Approach 1:
The Gripedo device transitions from a static mounted position to a dynamic portable configuration. When mounted on frames, it provides resistance for wrist flexion and extension. When used with sand or weights, it enables wrenching exercises, supination pronation, and rotations. This dynamic adaptability allows the device to provide resistance while maintaining flexibility of use across different exercise types.
3Reliability
If existing wrist rollers are designed for mounting on frames, then they provide stable support, but they lack portability and cannot be used without a frame
Solution Approach 1:
The Gripedo device is designed to function both when mounted on frames (providing stable support for wrist flexion and extension) and when used portably with sand or weights (enabling wrenching exercises, supination pronation, and rotations). This universal design resolves the contradiction by maintaining reliability in mounted use while adding portability for standalone exercises.

AI summary
The Gripedo device is a portable and multifunctional exercise apparatus that can be used alone or together with a variety of existing equipment. The Gripedo device includes a handle, a shaft and a plurality of fins. The handle, in various shapes and configurations, allows wrenching and twisting like motions of the supination and pronation of the hands, wrists, forearms, and internal and external rotation of shoulders. The user can also grip the shaft and conduct a variety of sport specific hold training. The user can also grip the shaft to perform wrist extensions and flexions or the handle to perform wrist extensions, wrist flexions, wrist ulnar deviation and wrist radial deviation. The plurality of fins on the shaft can be mounted to an existing apparatus or a weight. The Gripedo device can further be used with working against sand, rice, or similar granular material, can be used as gymnastic canes, for dips, pull-ups or push-ups, sled drags, single-arm deadlifts or carries, exercises using landmines, therapeutic exercises, goblet squats, sled, hammer-like wrist leveraging exercises, etc.
