Adjustable Rowing Machine Support for Height and Posture Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment for bent over rows lacks adjustability in height and angle, leading to improper posture and strain for users, particularly beginners, due to fixed dimensions that do not accommodate varying user body sizes.
Innovation Solution
A two-way row machine with an adjustable support unit in height and angle, allowing users to customize the distance between their hands and the handle, and featuring a rotation stopper unit for adjusting the handle's position, along with a footrest unit that fits individual body sizes and a handle unit that can change grip types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed height and angle exercise equipment is used, then device complexity is reduced, but adaptability to different user body sizes deteriorates
Solution Approach 1:
The support unit is designed with adjustable height and angle capabilities, allowing it to dynamically adapt to different user body sizes and exercise requirements. The height adjustment mechanism includes multiple height positions, and the angle adjustment mechanism allows rotation between different angles, transforming a static fixed structure into a dynamic adjustable one that maintains both simplicity and adaptability.
Solution Approach 2:
The invention changes the parameters of the support unit by providing multiple adjustable height positions and rotation angles. This allows the same device to accommodate users of different heights and body types without requiring multiple different equipment configurations, thereby improving adaptability while maintaining a relatively simple device structure.
2Ease of operation
If fixed position handle is used, then device complexity is reduced, but ease of operation deteriorates due to inability to adjust hand distance
Solution Approach 1:
The handle is designed to rotate together with the support unit when the support unit rotates. This dynamic connection allows the handle position to automatically adjust relative to the user's hands as the support unit angle changes, improving ease of operation without requiring a complex independent adjustment mechanism for the handle.
Solution Approach 2:
The rotation stopper unit serves multiple functions: it limits the rotation angle of the support unit, prevents over-rotation, and works together with the angle adjustment mechanism. This multi-functional design improves ease of operation while avoiding the need for separate complex control systems.
3Adaptability or versatility
If non-adjustable support unit is used, then manufacturing precision requirements are reduced, but adaptability to different exercise postures deteriorates
Solution Approach 1:
The support unit is divided into segmented adjustment mechanisms: a height adjustment mechanism with multiple discrete height positions and an angle adjustment mechanism with discrete rotation angles. This segmentation allows for standardized manufacturing of each position while still providing continuous adjustability across the full range of motion, balancing manufacturing precision requirements with adaptability.
Solution Approach 2:
The support unit incorporates dynamic adjustment capabilities through its height and angle adjustment mechanisms, allowing users to configure the support unit for different exercise postures and body types. The rotation stopper unit dynamically limits the rotation range to ensure safe operation while maintaining manufacturing simplicity through standardized positioning holes and stoppers.
