AI Workout Guidance Using Trajectory and Muscle Activation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users struggle to determine whether they are appropriately using fitness equipment based on their physical characteristics and workout capability, leading to ineffective workouts.
Innovation Solution
An AI workout guide device that includes a storage for muscle activation data, a sensor to detect workout trajectories, an AI processor to compare these trajectories with a guide, and a workout guider to adjust load or posture when deviations occur, providing real-time muscle contraction and relaxation information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fitness equipment is used without real-time guidance, then the workout can be performed freely, but the user cannot determine whether they are appropriately using the equipment according to their physical characteristics and workout capability
Solution Approach 1:
The system uses sensors to detect workout trajectories and compares them against pre-stored correct trajectory data to provide real-time feedback to users about their form and muscle activation, enabling them to adjust their workout accordingly
Solution Approach 2:
The patent replaces manual inspection of workout correctness with an automated sensor-based detection system that uses trajectory analysis to determine muscle activation and provide guidance
2Productivity
If real-time trajectory detection and analysis is implemented, then workout effectiveness is improved through real-time guidance, but device complexity increases due to sensors and processing requirements
Solution Approach 1:
The system pre-stores correct workout trajectories and muscle activation data before the workout begins, allowing real-time comparison during exercise without requiring complex on-the-fly analysis
Solution Approach 2:
The system creates a digital copy of the correct workout trajectory and compares it with the actual trajectory detected by sensors, simplifying the analysis process by working with pre-defined reference data rather than complex real-time generation

AI summary
An artificial intelligence (AI) workout guide device includes a storage storing one or more muscles activated when fitness equipment is used, a contribution of each of the one or more muscles, and an workout trajectory guide generated when accurately using the fitness equipment in a correct posture, a sensor configured to detect an workout trajectory corresponding to movement of a user moving the fitness equipment, an AI processor configured to determine whether a deviation between the workout trajectory detected by the sensor when the fitness equipment is moved in at least one direction matches the workout trajectory guide, and a workout guider configured to, when the deviation between the workout trajectory and the workout trajectory guide exceeds a preset value, guide to adjust an workout load of the fitness equipment or an workout posture.
