Multi-Directional Load Transmission for Compound Muscle Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing muscle training apparatuses primarily perform monotonous movements in one direction, leading to hardened muscles lacking flexibility and elasticity, as they do not facilitate compound movements in multiple directions.
Innovation Solution
A load transmission mechanism for training apparatuses that includes a main drive shaft unit, intermediate and perpendicular shaft units, and a sliding shaft unit, with rotation and tension transmission mechanisms, allowing for simultaneous multi-directional movements of the target body portion during exercise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a training apparatus performs monotonous movements in one direction, then the structure is simple and easy to operate, but the muscles become hardened and lack flexibility and elasticity
Solution Approach 1:
The patent introduces multi-directional movement capabilities by adding perpendicular shaft units and link mechanisms that enable the training apparatus to move the target body portion not only in the original direction but also in perpendicular directions, transforming single-directional linear movement into multi-dimensional compound movement, thereby improving muscle flexibility without significantly complicating the basic operational principle
2Adaptability or versatility
If a training apparatus enables compound movements in multiple directions, then muscle flexibility and elasticity are enhanced, but the device complexity increases
Solution Approach 1:
The patent divides the drive mechanism into multiple independent shaft units (main drive shaft unit, intermediate shaft unit, perpendicular shaft unit) and modular components (first rotation transmission unit, second rotation transmission unit, link mechanism). Each segment performs a specific function in the multi-directional movement chain, allowing the complex multi-directional movement capability to be achieved through coordinated action of simpler modular components rather than a single complex mechanism
3Adaptability or versatility
If a training apparatus uses a complex transmission mechanism for multi-directional movement, then compound movements are enabled, but the loss of time for operation increases
Solution Approach 1:
The patent designs the transmission mechanism so that the main drive shaft unit continuously drives the intermediate shaft unit and perpendicular shaft unit through engaged rotation transmission units, enabling continuous multi-directional compound movement without interruption. The link mechanism maintains continuous contact and force transmission, ensuring that the useful action of muscle loading continues seamlessly throughout the exercise range, reducing idle time and improving training efficiency
