Dumbbell With Orthogonal Handle For Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dumbbell weights, such as kettle bells, can be difficult to hold in a fixed position during exercises like lateral raises due to their shape, causing the handle to twist in the hand as the weight rotates towards the ground.
Innovation Solution
An improved dumbbell design featuring a base weight with lower braces and a horizontal handle between upper ends of the lower braces, with upper weights supported by upper braces forming a "dumbbell-like" structure. The handle is orthogonal to the axis between the upper and lower weights, and the upper weights can be curved to provide space for hand placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a kettle bell shape is used, then the weight can be lifted, but the handle twists in the hand as the weight rotates towards the ground due to gravity
Solution Approach 1:
The weight is divided into multiple segments (upper weights and lower weights) connected by braces, allowing each segment to be positioned independently to maintain proper orientation during exercise
Solution Approach 2:
The handle is repositioned from a vertical orientation to a horizontal orientation, changing the dimensional relationship between the handle and the weight axis, which prevents the handle from twisting during lateral raise exercises
2Device complexity
If the handle is positioned vertically, then the structure is simple, but it is difficult to hold in a fixed position during lateral raise exercises
Solution Approach 1:
The handle is repositioned from a vertical orientation to a horizontal orientation, changing the dimensional relationship between the handle and the weight axis, which prevents the handle from twisting during lateral raise exercises

AI summary
An improved dumbbell free weight is discussed, which includes one or more base weights, the dumbbell further having a pair of second, upper weights positioned above where the upper weights are suspended by upper braces extending from a handle attached to the one or more base weights.
