Modular Stretching Tool With Rotating Shafts for Adjustable Reach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fitness devices often restrict users due to weight and physical constraints, limiting maximum stretch and flexibility, and require multiple devices for exercising different anatomical regions, lacking proper gripping capabilities and adjustable lengths.
Innovation Solution
A fitness tool with a shaft and handles or straps at each end, featuring a rotational connecting mechanism allowing independent rotation and adjustable length, enabling users to perform various exercises with a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fitness devices are designed with fixed length and rigid structure, then manufacturing is simple, but they cannot accommodate different body sizes and stretching needs
Solution Approach 1:
The fitness device is divided into multiple segments (first shaft portion, second shaft portion, third shaft portion) that can be connected or disconnected. This segmentation allows the device to adjust its overall length to accommodate different body sizes and stretching requirements while maintaining a relatively simple individual component design.
Solution Approach 2:
The device incorporates dynamic connection mechanisms between shaft portions that allow for adjustable length configuration. The connection features enable the device to transition between different lengths based on user needs, providing adaptability without requiring a completely different device for each body type.
2Adaptability or versatility
If fitness devices have fixed gripping capabilities, then manufacturing is straightforward, but they cannot provide proper gripping capabilities for all users and anatomical regions
Solution Approach 1:
The device incorporates multiple interface features (grips, straps, loops) at different locations along the shaft portions that can be used for various gripping needs. These universal interface features can accommodate different hand sizes, grip styles, and anatomical regions without requiring multiple specialized devices.
Solution Approach 2:
Different sections of the shaft portions have different interface features tailored to specific gripping needs. For example, some sections may have larger grips for hands while others have smaller attachment points for fingers or feet, providing localized adaptability for different anatomical regions.
3Adaptability or versatility
If fitness devices are designed as single-function machines, then structure is simple, but users must purchase multiple devices for different anatomical regions
Solution Approach 1:
The fitness device is designed as a universal tool that can be configured for multiple anatomical regions through its adjustable length and various interface features. The same device can be used for arm stretching, leg stretching, chest exercises, and other anatomical regions by simply adjusting the shaft length configuration, eliminating the need for multiple specialized devices.
Solution Approach 2:
By segmenting the device into multiple shaft portions that can be connected or disconnected, the device can be configured for different anatomical regions. Users can connect more portions for longer reach needed for leg exercises or disconnect portions for shorter exercises targeting upper body regions.
4Length of moving object
If fitness devices have fixed length, then manufacturing is simple, but they limit stretching capability for users of different heights and body types
Solution Approach 1:
The device is segmented into multiple shaft portions with connection features that allow users to adjust the overall length by connecting or disconnecting these portions. This segmentation provides a simple yet effective length adjustment mechanism that accommodates users of different heights and body types without requiring complex mechanical systems.
Solution Approach 2:
The device incorporates dynamic length adjustment capabilities through its modular shaft portions that can be reconfigured. The connection features allow for easy length changes based on user needs, providing adaptability for different stretching requirements while maintaining structural integrity.

AI summary
A fitness tool for a user to use in performing stretching or other fitness activities may include a first member including (i) a first elongated shaft, the first elongated shaft including a first interface feature on a first end of the first elongated shaft, and (ii) a handle disposed at the second end. A second member may include a second elongated shaft, where the second elongated shaft may include a second interface feature at a first end of the second elongated shaft. The first and second interface features, when longitudinally engaged with one another, may enable the first and second shafts to rotate relative to one another. The second elongated shaft may include a hand or foot engagement mechanism.
