Stationary-Base Rowing Device With Rail-Guided Upper Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rowing devices lack improved configurations that enhance safety, reduce the risk of injury, and provide a more realistic rowing experience while maintaining a compact footprint.
Innovation Solution
A rowing device design featuring a stationary lower portion and a slidable upper portion with a seat assembly that moves independently, incorporating a rail system for smooth movement, a resistance element positioned in front of the user, and protective members to prevent injury, mimicking the motion of an actual rowing boat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seat assembly is coupled to the moving upper portion, then the rowing motion is more realistic, but the seat may slide or move unintentionally during exercise
Solution Approach 1:
The rowing device is divided into two separate portions: a stationary lower portion that supports the seat assembly, and a moving upper portion that contains the resistance element. This segmentation allows the seat to remain stable while the upper portion moves during the rowing stroke, resolving the contradiction between realistic motion and seat stability.
2Area of stationary object
If the upper portion moves behind the user during exercise, then the device footprint is reduced, but the resistance element may come into contact with the user
Solution Approach 1:
The resistance element is positioned in front of the user along the longitudinal axis, while the upper portion moves behind the user in a different spatial plane. This dimensional arrangement allows the moving upper portion to compact behind the seat without the resistance element contacting the user, simultaneously reducing footprint and preventing injury.
3Reliability
If the seat assembly is fixed to the stationary lower portion, then the seat remains stable during use, but the device occupies more space
Solution Approach 1:
The device is segmented into a stationary lower portion with the seat assembly and a moving upper portion. This allows the seat to be firmly anchored to the stationary base for stability, while the moving upper portion can slide behind the user during exercise, reducing the overall footprint without compromising seat stability.

AI summary
According to some embodiments, a rowing device for exercise comprises a lower or base portion configured to be positioned along a ground surface, the lower or base portion configured to remain stationary during use, an upper portion configured to slidably move relative to the lower or base portion during use, wherein the upper portion comprises a resistance element, a handle assembly and a footrest assembly, and a seat assembly coupled to the lower or base portion, wherein the seat assembly is configured to not slidably move relative to the upper portion when the upper portion is moved relative to the lower or base portion.
