EMS Intensity Display and Tracking for Intuitive Workout Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Electrical Muscle Stimulation (EMS) systems lack intuitive and meaningful feedback for users regarding the intensity of electrical impulses, making it difficult for users to adjust settings appropriately, and they only store snapshot data of workout intensities, which may not accurately reflect a user's progress.
Innovation Solution
The system formulates and displays meaningful and intuitive intensity values by multiplying channel intensity values by a predefined number to generate displayable values, allowing for a global intensity value that provides user feedback, and tracks intensity history to determine more suitable starting intensities for subsequent workouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing EMS systems display channel intensity values as numbers between 0 and 100 calculated as a function of both channel intensity value and master intensity value, then the system can provide adjustable intensity control, but the displayed values are not intuitive or meaningful to users
Solution Approach 1:
The patent transforms the intensity display parameter from a calculated composite value (Master × Channel) to a direct representation of actual electrical current intensity. By changing what is displayed from abstract percentages to concrete current values, the system maintains adjustability while improving user comprehension of the actual intensity being delivered.
2Productivity
If existing EMS systems store only a point-in-time snapshot of ending channel intensities, then the system can determine starting intensities for subsequent workouts, but the starting intensities may be ill-suited for users
Solution Approach 1:
The patent applies preliminary action by storing and analyzing the complete intensity progression history before determining starting intensities for subsequent workouts. Rather than relying solely on the final intensity snapshot, the system prepares comprehensive historical data that enables more accurate and personalized intensity recommendations for future sessions.
Solution Approach 2:
The system implements feedback by using the full intensity history to continuously refine and adjust starting intensity recommendations. The complete workout intensity trajectory provides feedback information that helps the system learn user responses and optimize subsequent workout parameters for better suitability.
Data Source
AI summary
Described herein are techniques, devices, and systems for formulating, tracking, displaying, and using electrical muscle stimulation (EMS) intensity values that are meaningful and intuitive. Electrical impulses may be delivered via multiple electrodes of an EMS suit in accordance with pulse intensity settings, the pulse intensity settings comprising multiple channel intensity values associated with multiple channels. Each channel intensity value can be multiplied by a predefined number to generate displayable channel intensity values, and a global intensity value can be derived from the displayable channel intensity values. The global intensity value can be presented on a display, such as by presenting the global intensity value as a graphic overlaying media content featuring an instructor conducting a workout session.
