Solution Overview
Problem
Aging populations face challenges with reduced muscular strength and joint problems, necessitating assistive devices that can help with walking and exercise with reduced effort, but existing technologies lack effective control mechanisms for personalized workout loads based on user heart rate.
Innovation Solution
An electronic device with communication and processing capabilities that sets a target heart rate, determines a corresponding workout load, and controls wearable devices to provide the appropriate load, integrating with sensors and motors to adjust torque and resistance forces in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed workout load is provided to users, then the device structure is simple, but the exercise effectiveness and safety for users with reduced muscular strength or joint problems is insufficient
Solution Approach 1:
The system continuously monitors user heart rate through sensors and uses this feedback to dynamically adjust workout load parameters. The controller receives heart rate data, compares it against target ranges, and automatically modifies resistance forces or motor assistance to keep the user within the desired heart rate zone, thereby adapting the exercise to individual physiological states without requiring complex manual intervention
Solution Approach 2:
The workout load is transformed from a static fixed value to a dynamic parameter that changes in real-time based on user response. The system adjusts resistance forces, motor torque, or assistance levels continuously or periodically based on heart rate fluctuations, allowing the same device to provide customized exercise intensity for different users and workout stages without requiring multiple specialized devices
2Productivity
If personalized workout control is implemented, then exercise effectiveness is improved, but the device complexity increases
Solution Approach 1:
The system performs automated self-adjustment based on pre-programmed protocols and real-time heart rate data. The controller autonomously determines when to increase or decrease workout intensity without requiring user input or external intervention, using built-in algorithms that automatically interpret heart rate data and translate it into appropriate load adjustments, thereby reducing the need for complex user interfaces or manual control mechanisms
Solution Approach 2:
The system modifies key workout parameters such as resistance force, motor assistance level, or exercise intensity based on heart rate data. By changing these parameters dynamically rather than requiring multiple discrete settings or complex mechanical adjustments, the system achieves personalized exercise control through relatively simple parameter modulation, improving exercise efficiency while limiting the increase in device complexity

AI summary
An electronic device may: set a target heart rate for a user wearing a wearable device (e.g., walking assist device); receive information of the user's current heart rate; determine, on the basis of the current heart rate and the target heart rate, target exercise load such that the user's heart rate can correspond to the target heart rate; and control the wearable device such that the target exercise load is provided to the user. Various other embodiments may also be possible.
