Motor-Driven Exercise Machine With Sensor-Based Safety Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise equipment, such as free weights and mechanical exercise machines, pose risks of injury and fail to adequately activate the user's stabilizer muscles, and existing systems lack effective safety measures to prevent accidents during use.
Innovation Solution
An exercise machine with a motor-driven mechanism and sensor system that applies controlled forces to an exercise bar, utilizing sensors to detect user interactions and safety parameters to prevent unsafe conditions by adjusting or stopping the motor force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If free weights are used for exercise, then muscle building and shaping are achieved, but risk of injury increases
Solution Approach 1:
A motor-driven cable system acts as an intermediary between the weight stack and the exercise bar, providing controlled resistance while eliminating the need for users to directly handle free weights. The motor controls the force application to prevent injury while maintaining exercise effectiveness
Solution Approach 2:
The patent replaces the purely mechanical free weight system with an electromechanical system where a motor controls the resistance application. This substitution allows for precise control of force magnitude and direction, reducing injury risk while maintaining muscle-building benefits
2Ease of operation
If mechanical exercise machines are used, then exercise guidance is provided, but stabilizer muscles are not adequately activated
Solution Approach 1:
The system transitions from fixed mechanical guides to dynamic motor-controlled resistance that can adapt during exercise. The motor adjusts force application in real-time based on sensor feedback, allowing natural movement variations that engage stabilizer muscles while maintaining proper exercise form through guided resistance
3Productivity
If conventional exercise equipment is used, then exercise performance is achieved, but safety measures are insufficient to prevent accidents
Solution Approach 1:
The system incorporates sensors that continuously monitor exercise performance parameters and provide feedback to a controller. This feedback loop enables real-time detection of unsafe conditions and automatic adjustment of resistance or termination of exercise, maintaining both performance and safety
Solution Approach 2:
The motor-driven system can pre-position the exercise bar and apply controlled resistance before the user begins exercising. Safety protocols are pre-programmed to prevent dangerous force applications before they can cause injury, rather than merely reacting to accidents after they occur
