Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rowing machines do not provide optimal rowing posture and adjustability of resistance, leading to inadequate exercise experience and limited health benefits.
Innovation Solution
A rowing machine with adjustable inclined rails and a support structure that allows for variable resistance, incorporating a movable user support and foot support system with rollers, pulleys, and springs to provide both concentric and eccentric resistance, enhancing user posture and exercise dynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional rowing machines use fixed horizontal rails, then the structure is simple, but the rowing posture is not optimal and resistance adjustability is limited
Solution Approach 1:
The patent applies the dynamics principle by making the rails adjustable in inclination angle rather than fixed. The support structure allows the rails to be positioned at different angles relative to the horizontal plane, enabling dynamic adaptation to user needs and providing optimal rowing posture through variable resistance angles.
Solution Approach 2:
The patent implements parameter changes by allowing the inclination angle of the rails to be varied. This parameter adjustment changes the resistance characteristics and rowing mechanics, enabling users to modify the exercise intensity and posture according to their fitness level and training goals.
2Adaptability or versatility
If conventional rowing machines provide only concentric resistance, then the device is simple, but the exercise effectiveness is limited
Solution Approach 1:
The patent applies segmentation by dividing the resistance mechanism into separate concentric and eccentric components. The concentric resistance is provided by the spring mechanism during the pulling phase, while eccentric resistance is provided during the return phase, allowing independent optimization of each resistance type.
Solution Approach 2:
The patent implements periodic action by providing alternating concentric and eccentric resistance throughout the rowing cycle. The resistance type changes periodically with each stroke phase, creating a comprehensive workout that utilizes both muscle contraction modes for enhanced exercise effectiveness.

AI summary
A rowing exercise device comprises a support structure; a movable user support movably associated with the support structure for movement relative to the support structure; a movable foot support movably associated with the support structure for movement relative to the support structure; a handle; and a rowing assembly operatively associated with the handle and at least the movable foot support to cause at least the movable foot support to move relative to the support structure with movement of the handle so that both a user s body and one or both feet move relative to the support structure with movement of the handle.
