Dynamic Load Control for Exercise Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise training apparatuses cannot adjust the exercise load in real-time based on the physical condition of the user or the perceived exertion level during the exercise, limiting the ability to tailor the workout experience.
Innovation Solution
An electric training apparatus equipped with a load motor, physiological response detection units, and a control unit that adjusts the load based on detected physiological responses and user input, allowing for dynamic load adjustments during exercise to match a target exertion level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If load adjustment is performed based on pre-set upper limit load values, then the exercise load can be controlled to prevent exceeding target pulse rate, but the system cannot adapt to real-time physical conditions or perceived exertion levels during exercise
Solution Approach 1:
The system continuously monitors physiological responses (pulse rate, blood pressure, respiratory rate) during exercise and uses this feedback to dynamically adjust the load motor output. The control unit compares real-time physiological data with target values and automatically modifies the exercise load to maintain optimal physiological parameters, enabling both safety control and real-time adaptation.
Solution Approach 2:
The load upper limit value is transformed from a static pre-set parameter into a dynamic parameter that automatically adjusts during exercise based on real-time physiological monitoring. The system transitions from fixed load adjustment to adaptive load adjustment, allowing the exercise load to respond continuously to changing physical conditions and perceived exertion levels.
2Adaptability or versatility
If the load motor is controlled to maintain target physiological responses, then the exercise can be personalized to user conditions, but the system complexity increases due to continuous monitoring and adjustment
Solution Approach 1:
The control unit performs multiple functions: it monitors physiological responses, calculates load adjustments, and controls the load motor through a single integrated system. By combining these functions in one control unit rather than separate systems, the patent achieves personalized exercise control while managing device complexity through functional integration.

AI summary
An electric training apparatus is configured to apply, by a load motor, a load on a rotating body configured to apply a load on an exercising person, detect an exercise physiological response value of the exercising person and a number of revolutions of the rotating body, perform control for gradually increasing the load of the load motor toward a set load upper limit value so that a detection result of the exercise physiological response value of the exercising person approaches a target exercise physiological response value set in advance, and change, before an exercise or during the exercise by the exercising person, the load upper limit value in response to a control command input based on a state of the exercising person, a state of the control, and a perceived exertion scale for the exercising person.
