High-Low Machine Handle Angle Adjustment for Muscle Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-low machines limit intense exercise due to limited grip options and inability to adjust handle angles, failing to accommodate diverse muscle groups and user body sizes effectively.
Innovation Solution
A high-low machine with adjustable handle angles via first and second angle adjusters on orthogonal axes, allowing for one or both arm motions, and adjustable seat and knee support features to accommodate various user sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed grip design is used in existing high-low machines, then the structure is simple and easy to manufacture, but the user cannot exercise diverse muscle groups intensively and the machine lacks adaptability to different user needs
Solution Approach 1:
The handle structure is transformed from a fixed static design to a dynamic adjustable design. The first angle adjuster allows the handle to rotate around a first axis, and the second angle adjuster enables rotation around a second axis orthogonal to the first axis. This dynamic configuration lets users adjust the handle angle to various positions, enabling intensive exercise of diverse muscle groups while maintaining reasonable structural complexity through modular adjuster components.
2Adaptability or versatility
If multiple angle adjusters are added to enable handle angle adjustment, then the machine can accommodate diverse muscle groups and user sizes, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The angle adjustment mechanism is segmented into two independent adjusters: the first angle adjuster for adjusting the handle angle around a first axis, and the second angle adjuster for adjusting around a second axis orthogonal to the first axis. Each adjuster is a separate modular component that can be manufactured and assembled independently, reducing overall manufacturing difficulty while providing comprehensive angle adjustment capability for diverse exercise needs.
3Adaptability or versatility
If the machine is designed to accommodate various user body sizes with adjustable seat and knee support, then the machine becomes more versatile, but the structural complexity and space requirements increase
Solution Approach 1:
The adjustment mechanisms utilize multi-dimensional rotation capabilities. The first angle adjuster rotates around a first axis, and the second angle adjuster rotates around a second axis orthogonal to the first axis, creating a three-dimensional adjustment space. This dimensional approach allows comprehensive adaptability to various user body sizes and exercise preferences without requiring excessive linear space or increasing the machine's footprint.
