Repetition Sensor Using Electricity Generator for Anaerobic Exercise Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anaerobic exercise systems lack accurate monitoring of repetitions and sets due to their non-rotation-based nature, leading to inaccurate data collection and user reliance on personal recording, as existing monitoring technologies are not suited to detect short or inconsistent movements.
Innovation Solution
A repetition sensor that generates electrical signals in response to exercise motion, using an electricity generator coupled to a moving component, allowing for differential signal detection of positive and negative strokes, and software modules to interpret these signals for accurate repetition counting, set tracking, and movement analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional monitoring apparatus (odometer, speedometer) are used on anaerobic exercise devices, then the device structure remains simple, but the measurement precision of repetitions is insufficient
Solution Approach 1:
The patent replaces mechanical monitoring apparatus (odometers, speedometers) with an electrical sensing system that uses electrical signals to detect and measure repetition movements. This substitution enables precise measurement of anaerobic exercise repetitions while maintaining system simplicity through electronic rather than mechanical means.
2Measurement precision
If electrical sensing systems are implemented to accurately detect repetitions, then measurement precision improves, but the device complexity increases
Solution Approach 1:
The patent introduces an intermediary electrical sensing system that translates mechanical movement into electrical signals for accurate repetition detection. This intermediary layer enables precise measurement without requiring complex mechanical monitoring apparatus, as the electrical system acts as a mediator between the user's movement and the monitoring function.
3Adaptability or versatility
If rotation-based monitoring is used on anaerobic devices, then the monitoring system remains simple, but the adaptability to various anaerobic motions is limited
Solution Approach 1:
The patent implements a universal electrical sensing system that can detect and measure various types of anaerobic motions (pulling, pushing, lifting, pressing) through a single monitoring apparatus. This multi-functional system replaces specialized rotation-based monitors, enabling the same device to adapt to diverse exercise movements without increasing complexity.

AI summary
An exercise repetition sensor comprises an electricity generator, such as an electricity generator, which is coupled to an exercise system, where the electricity generator is capable of sensing exercise movements of any size or intensity on the exercise system. The electricity generator can be based on a number of electrical, magnetic, or optical sensing principles. For example, an electricity generator comprising an electricity generator includes a spindle that is coupled to one or more parts that move in proportion to an applied force. The voltage-generator generates an electrical current as the spindle moves, and sends the electrical current to an electronic display interface. In one embodiment, the voltage-generator sends a positive direct current through one of two circuit wires to the electronic console, such that the electronic console can immediately identify that the user has performed an exercise repetition.
