Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current strength training methods, such as weight training and resistance training, lack safe and convenient ways to perform exercises effectively, as they rely on gravity or variable elastic/hydraulic forces, which can be unsafe and inconvenient.
Innovation Solution
A strength training machine with a motor-driven bar system that moves up and down at a constant rate, allowing users to push or pull against the bar without it moving, providing a customizable resistance based on the user's force exertion, independent of weight or gravity, and offering adjustable speed settings for cardiovascular benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weight training uses gravity to oppose muscle contraction, then strength training can be performed, but the method lacks safe and convenient ways to perform exercises
Solution Approach 1:
The patent replaces traditional gravity-based weight training with a motor-driven bar system that provides controlled mechanical resistance. The motor controls the bar's movement and resistance levels, eliminating the need for heavy weights and manual spotting, thereby improving both safety and convenience while maintaining strength training effectiveness
Solution Approach 2:
The machine enables users to perform exercises independently without requiring spotters or assistance. The motorized system automatically controls the bar's movement and resistance, allowing users to train alone safely and conveniently, thus resolving the contradiction between safety and ease of operation
2Reliability
If resistance training uses variable elastic/hydraulic forces, then muscle strength can be increased, but the method lacks safe and convenient ways to perform exercises
Solution Approach 1:
The patent replaces variable elastic/hydraulic resistance systems with a motor-driven mechanical bar system. The motor provides controlled, consistent resistance that is easier to manage and safer to use, eliminating the complexities and safety concerns associated with traditional resistance training equipment while maintaining training effectiveness
3Productivity
If the bar moves at a constant rate controlled by motor, then cardiovascular benefits are enhanced, but the resistance must be customized based on user force
Solution Approach 1:
The system automatically adjusts resistance based on the user's force application without requiring manual intervention. The motorized bar responds to the user's effort and maintains appropriate resistance levels, simplifying the customization process while enhancing cardiovascular workout efficiency through controlled movement speed
Solution Approach 2:
The motorized system incorporates feedback mechanisms that monitor the user's force application and adjust the bar's movement and resistance accordingly. This automatic feedback loop customizes the workout to the user's capabilities, improving cardiovascular efficiency without adding complex manual adjustment mechanisms

Data Source
AI summary
This patent discloses a machine to assist a person in strength training. The strength training machine may have a bar supported between two uprights. A motor and mechanisms may cause the bar to move up and down at a constant rate. A person may position themselves above, below, or to a side of the bar. As the bar moves, a person may push or pull against the resistance provided by the moving bar. The motor and mechanisms may prevent the bar from moving in response to the person pressing or pulling against the bar, no matter how hard the person presses or pulls on the bar.
