Adjustable Two-Way Row Machine for Proper Posture Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment for bent over rows is not adjustable in height and angle, leading to improper posture and potential safety hazards for users, particularly beginners, due to fixed dimensions that do not accommodate varying user body sizes.
Innovation Solution
A two-way row machine with a support unit that is adjustable in height and angle, allowing users to customize the distance between their hands and a handle, featuring a rotation stopper unit for precise adjustments and a footrest unit that fits individual body sizes, along with a handle unit that can change grip types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If exercise equipment has fixed height and angle, then manufacturing is simple, but it cannot accommodate different user body sizes leading to improper posture
Solution Approach 1:
The support unit is designed with adjustable height and angle capabilities, transforming a static fixed-configuration structure into a dynamic one that can be modified according to user needs. The height adjustment mechanism allows the support surface to be raised or lowered, while the angle adjustment mechanism enables tilting the support surface to different inclinations, both controlled through user-operated adjustment devices.
Solution Approach 2:
The invention changes the physical parameters of the support unit by providing multiple discrete height positions and angle configurations. The height adjustment mechanism provides several predetermined height levels, and the angle adjustment mechanism offers multiple inclination angles, allowing users to select optimal parameters for their body dimensions and exercise requirements.
2Ease of operation
If exercise equipment is fixed in dimensions, then device complexity is low, but exercise efficiency decreases for beginners who cannot maintain proper posture
Solution Approach 1:
The support unit incorporates height and angle adjustment mechanisms that enable the equipment to adapt dynamically to different user body sizes. This dynamic capability allows beginners to configure the equipment to match their specific anthropometric measurements, thereby maintaining proper exercise posture more easily.
Solution Approach 2:
The adjustable support unit serves multiple functions: it can be configured for different user heights, different exercise intensities, and different body types. This multi-functionality allows a single piece of equipment to cater to diverse user needs, including beginners who require customized positioning for proper form.
3Reliability
If exercise equipment has fixed configuration, then manufacturing cost is low, but safety accidents increase due to improper usage
Solution Approach 1:
The support unit's height and angle adjustability allows users to configure the equipment according to their body dimensions, reducing the risk of improper posture and associated safety accidents. By enabling customization, the equipment adapts to individual users rather than requiring users to adapt to fixed equipment dimensions.
Solution Approach 2:
The equipment allows users to perform preliminary adjustments of height and angle before beginning exercise, ensuring proper configuration is established in advance. This preliminary customization prevents safety issues during exercise execution by ensuring the equipment is properly configured for each user's body size and capability.
