Dual-Cable Exercise Machine With Independent Resistance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise machines lack the ability to variably adjust resistance during gymnastic exercises, with gravitational and electromagnetic systems either maintaining constant resistance or being interdependent through a single resistant member.
Innovation Solution
An exercise machine with independent first and second exercise devices, each equipped with a cable, actuator, and logic control unit, allowing for adjustable resistance through actuators and programmable training protocols, along with sensors for user positioning and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single resistant member is used to connect multiple cables, then device complexity is reduced, but the resistance perceived on each cable becomes interdependent and cannot be independently adjusted
Solution Approach 1:
The patent divides the single resistant member into multiple independent resistant members, with each cable having its own dedicated resistant member. This segmentation allows each cable's resistance to be independently adjusted without affecting other cables, resolving the interdependence issue while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
The patent implements dynamic resistance adjustment for each cable through electronic control systems that can vary the resistance levels independently in real-time. This allows the resistance characteristics to be dynamically adapted to different exercise requirements and user needs, providing versatility without requiring a completely rigid structural overhaul.
2Device complexity
If gravitational resistant members are used, then device complexity is reduced, but the resistant force remains constant and cannot be varied during exercise
Solution Approach 1:
The patent replaces pure gravitational resistant members with electromechanical or electromagnetic resistant members that can actively control and vary the resistant force. This substitution enables dynamic adjustment of resistance during exercise through electronic control, while the overall mechanical structure remains relatively simple and easy to manufacture.
Solution Approach 2:
The patent enables continuous variation of resistance parameters during exercise execution through electronic control systems. The resistant force can be adjusted in real-time based on exercise phase, user performance, and programmed training protocols, transforming the static gravitational resistance into a dynamically adjustable parameter without complicating the basic resistant member structure.
