Dynamic Rowing Machine With Vertical-Rearward Seat Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rowing machines limit the movement of the seat and rower to axial motion, failing to simulate the dynamic motion of a rower operating a scull in water, which is less realistic for training purposes.
Innovation Solution
A dynamic rowing machine with a double framework design, incorporating lifting profiles that allow the seat and rowing scull to move in both horizontal and vertical directions, simulating the motion of a rower in a scull by supporting a dynamic framework along continuous paths formed by rising and rearward segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional rowing machines limit movement to axial motion along rails, then the machine structure remains simple and stationary, but the motion realism and training effectiveness deteriorate
Solution Approach 1:
The patent applies the Dynamics principle by transforming the stationary rail system into a dynamic lifting profile system. The seat assembly moves along three-dimensional curved paths defined by rising and rearward segments, allowing simultaneous vertical and horizontal motion. This dynamic path system realistically simulates scull motion while maintaining structural simplicity through fixed framework guides.
Solution Approach 2:
The patent implements Another dimension by adding vertical motion to the traditional horizontal-only rail system. The lifting profiles incorporate rising segments that enable the seat assembly to move vertically while also moving horizontally along rearward segments, creating three-dimensional motion paths that authentically replicate rowing dynamics.
2Device complexity
If the rowing machine allows only axial movement of the seat, then the mechanical system remains simple, but the simulation of true rowing motion deteriorates
Solution Approach 1:
The patent applies Segmentation by dividing the lifting profile into distinct functional segments: rising segments for vertical motion and rearward segments for horizontal motion. This segmentation allows the complex three-dimensional motion path to be achieved through simple, modular framework elements that maintain mechanical simplicity while ensuring reliable motion simulation.
3Ease of manufacture
If conventional rowing machines use stationary frameworks only, then manufacturing and setup are simple, but the dynamic rowing experience deteriorates
Solution Approach 1:
The patent transforms the static framework into a dynamic system by incorporating lifting profiles with curved three-dimensional paths. The framework remains stationary and simple to manufacture, but the guided motion along rising and rearward segments creates dynamic rowing motion that enhances operational realism and user experience.

AI summary
A dynamic rowing machine configured to simulate a motion of a rower working through a rowing motion of a rowing scull is provided. The dynamic rowing machine includes a stationary framework having one or more lifting profiles. Each of the lifting profiles has one or more segments forming a rising path and one or more segments forming a horizontally rearward path. The one or more segments forming the rising path and the one or more segments forming the horizontally rearward path form a continuous path. A dynamic framework is supported for movement along the continuous paths of the one or more lifting profiles of the stationary framework. Movement of the dynamic framework along the continuous paths of the one or more lifting profiles of the stationary framework results in upward and rearward movement of the dynamic framework.
