Combination Exercise and Massage Device with Resilient Outer Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercise and massage devices lack versatility and effectiveness in providing both resistance for workouts and massage functionality with a single device, often requiring separate tools for different exercises and massage techniques.
Innovation Solution
A combination exercise and massage device with a hollow, spherical body and a centrally positioned handle, featuring a rigid core and a resilient outer layer, allowing for various modes of use such as dumbbell, medicine ball, and massage, with adjustable weight and texture for enhanced grip and pressure distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate devices are used for exercise and massage, then each device can be optimized for its specific function, but the user needs to carry and manage multiple devices
Solution Approach 1:
The patent combines exercise and massage functions into a single device by integrating a resilient outer layer with projections onto a weight structure, allowing the same object to serve both workout and massage purposes
Solution Approach 2:
The device is designed with multiple functions: the weight portion provides resistance for exercise, while the projections on the resilient outer layer provide massage functionality, making one device serve multiple purposes
2Adaptability or versatility
If a single device provides both exercise and massage functions, then versatility is improved, but the device structure becomes more complex
Solution Approach 1:
The device is segmented into distinct functional zones: a weight portion for exercise resistance and a massage portion with projections on the resilient outer layer, allowing each segment to perform its specific function independently
Solution Approach 2:
The device uses composite construction with an inner weight structure and an outer resilient layer, combining materials with different properties to achieve both exercise and massage functions in one device
3Strength
If the device has a rigid structure for exercise, then resistance is effective, but it cannot provide the flexibility needed for massage
Solution Approach 1:
The device combines a rigid inner weight structure that provides exercise resistance with a resilient outer layer that provides flexibility and cushioning for massage, allowing both rigid and flexible properties to coexist in different portions of the same device
4Force
If the device provides adjustable resistance, then workout effectiveness is improved, but the device design becomes more complex
Solution Approach 1:
The device provides adjustable resistance by allowing users to modify parameters such as the amount of filling material in the weight portion or the hardness of the resilient outer layer, achieving variable resistance without complex mechanical adjustment mechanisms

AI summary
An exercise and massage device utilizes a substantially spherical body having a central cavity that extends to opposite sides of the spherical body so that the cavity forms openings on opposite sides of the spherical body. The spherical body has an outer core of a first resilient hardness. A single rigid handle is positioned within the cavity. The openings of the cavity are sized and configured for allowing a user to access and manually grasp the handle through either opening. A resilient outer layer surrounds the outer core of the spherical body and provides an exterior surface of the spherical body. The resilient outer layer has a second resilient hardness that is less than that of the first resilient hardness of the outer core of the spherical body to provide a cushioning effect when the device is used in a massage mode. The device is weighted to provide a total weight of the device of from 2 lbs or more.
