Rotating Exercise Grip With Nested Bearing Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment grips are typically stationary, causing user discomfort and limiting the ability to maximize workouts.
Innovation Solution
A grip apparatus with a freely rotatable handle is designed, comprising a first annular member and a second annular member with a bearing, allowing the second annular member to rotate relative to the first, which is connected to a weight system for exercise equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stationary grip is used in exercise equipment, then the structure is simple and stable, but user comfort is reduced and workout effectiveness is limited
Solution Approach 1:
The grip apparatus transitions from a stationary structure to a dynamic one by incorporating a rotatable handle member that can freely rotate about its longitudinal axis. This dynamic element allows the handle to move with the user's hand during exercise, improving comfort and effectiveness without significantly complicating the overall structure.
Solution Approach 2:
The grip apparatus uses a nested structure where the handle member is positioned within the grip body, and bearing races are nested within annular chambers formed by concentric annular members. This nesting approach allows multiple functional components to be integrated in a compact arrangement, adding rotation capability without proportionally increasing external dimensions or complexity.
2Productivity
If a freely rotatable handle is implemented, then workout effectiveness is maximized and user comfort is improved, but the device complexity increases due to additional components
Solution Approach 1:
The bearing races serve multiple functions: they enable free rotation of the handle, provide structural support within the grip apparatus, and facilitate smooth movement during exercise. This multi-functionality reduces the need for additional separate components, allowing the apparatus to achieve enhanced workout effectiveness without a proportional increase in complexity.
Solution Approach 2:
The grip apparatus is segmented into distinct functional components (grip body, handle member, bearing races, annular members) that can be independently manufactured and assembled. This segmentation allows for simplified production and maintenance while enabling the complex function of free rotation. Each segment performs a specific function, and their combination achieves the overall goal of improving workout effectiveness.
