Horizontal Rowing Machine with Swivel Handles and Adjustable Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rowing machines have fixed grips and axes of motion, limiting their adaptability to different user sizes and muscle training needs, and do not effectively transfer reaction force to the legs during exercise.
Innovation Solution
A horizontal unilateral rowing machine with adjustable hand grips, seating, and foot positions, featuring swivel handles and a chest pad that allows for dynamic grip changes and varied motion planes, enabling users to perform exercises in multiple positions and angles, and incorporating weight plates and elastic bands for resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed grips and axes of motion are used in conventional rowing machines, then the structure is simple and stable, but the adaptability to different user sizes and muscle training needs is limited
Solution Approach 1:
The patent applies dynamics by making the grip position adjustable along the handle and allowing the handle itself to be repositioned on the frame. This enables the rowing machine to adapt to different user sizes and training needs by adjusting the grip location, while maintaining a relatively simple overall structure through modular adjustment mechanisms rather than complex multi-component systems.
Solution Approach 2:
The rowing machine achieves universality through multiple adjustable components including the movable grip, repositionable handle, and adjustable seat position. These universal adjustment features allow a single machine to serve multiple training purposes and accommodate various user sizes without requiring multiple specialized devices.
2Force
If fixed axes of motion are used for hands and legs, then the machine structure is simplified, but the reaction force is not effectively transferred to the legs during exercise
Solution Approach 1:
The patent implements dynamic motion axes by allowing the handle to be repositioned at different locations on the frame, which changes the angle and plane of motion for both the upper body and legs. This dynamic adjustment enables optimal force transfer to the legs by aligning the motion path with the user's anatomy, while avoiding complex mechanical linkages through straightforward repositioning mechanisms.
3Adaptability or versatility
If adjustable hand grips, seating, and foot positions are provided, then the machine can target various muscle groups effectively, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the adjustment system into independent modular components: adjustable grip position on the handle, repositionable handle on the frame, and adjustable seat position. Each segment can be adjusted independently to target specific muscle groups, while the modular nature keeps each individual adjustment mechanism simple and manageable.
4Ease of operation
If swivel handles are used to enable dynamic grip changes, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The swivel handle incorporates dynamics by allowing rotation and movement in multiple directions to accommodate natural rowing motion and different grip preferences. This dynamic capability improves ease of operation by enabling users to adjust their grip dynamically during exercise, while the swivel mechanism itself remains a relatively simple rotational joint rather than a complex multi-degree-of-freedom system.
