Back Exercise Machine with Multi-Plane Cable Resistance Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment often subjects users to unnatural body positions and counterproductive stress, leading to potential injury and inadequate engagement of muscle groups, as it typically uses fixed resistance paths that do not mimic daily activities.
Innovation Solution
The development of exercise machines with cable connections and adjustable movement paths that allow users to maintain a biomechanically correct position through natural arcing motions, engaging additional muscle groups and providing resistance assistance, thus enabling a full range of motion and improved comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed resistance path machines are used, then the exercise targets a specific muscle, but the movement pattern does not mimic daily activities and causes unnatural body positions
Solution Approach 1:
The resistance path is made dynamic and adjustable rather than fixed. The cable connection system allows the resistance path to be reconfigured for different exercises and movement patterns, enabling the machine to adapt to various functional movement requirements while maintaining natural body positions throughout the range of motion.
Solution Approach 2:
The invention transitions from single-plane fixed motion to multi-plane adjustable motion. By allowing the resistance path to operate in multiple dimensions and planes through cable connections and adjustable guides, the machine can replicate the complex three-dimensional movement patterns of daily activities while keeping the user in natural biomechanical positions.
2Ease of operation
If fixed pattern motion is used, then the exercise is simple to perform, but it does not engage additional muscle groups and provides limited functional benefit
Solution Approach 1:
The exercise machine is designed with universal functionality to perform multiple exercises targeting different muscle groups. The cable connection system and adjustable resistance paths allow a single machine to replicate various functional movement patterns, engaging different muscle groups while maintaining operational simplicity through standardized cable attachment points and guides.
3Ease of operation
If cable connections with adjustable resistance paths are used, then user comfort and full range of motion are improved, but the device complexity increases
Solution Approach 1:
The resistance path system is segmented into modular components including cable sections, connection points, and adjustable guides. This segmentation allows each component to be independently positioned and adjusted to create the desired resistance path, simplifying the overall design while enabling complex adjustable movement patterns and improving user comfort.
