Exercise Machine Safety System Using Physiological Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise machine safety systems fail to effectively monitor and prevent users with poor or critical health states from engaging in intense exercise, posing a safety hazard.
Innovation Solution
A safety ensuring system that uses NFC tags, physiological detection instruments (including blood pressure meters, electrocardiography machines, and oximeters) to assess users' physiological states and restrict exercise machine usage based on their condition, preventing users with abnormal states from exercising.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art monitoring systems are used to track user health state during exercise, then health monitoring capability is provided, but the system fails to prevent users in poor health state from exercising, resulting in inadequate safety protection
Solution Approach 1:
The system performs preliminary detection of user physiological state before allowing exercise machine operation. The control device queries the physiological state data in advance, and only permits operation when the state is normal. This preventive approach ensures safety before the harmful event can occur, rather than just monitoring during exercise.
Solution Approach 2:
The control device acts as an intermediary between the physiological detection device and the exercise machine. It receives physiological state data, evaluates it against safety criteria, and controls the machine's operation accordingly. This intermediary layer enables safety enforcement without requiring direct modification of the exercise machine hardware.
2Reliability
If the system restricts exercise machine usage for users with abnormal physiological states, then user safety is improved, but user convenience and accessibility are reduced
Solution Approach 1:
The system changes the operational parameters of the exercise machine based on the user's physiological state. When the state is normal, full operation is permitted. When abnormal, the system adjusts by restricting operation or preventing machine startup. This dynamic parameter adjustment ensures safety while maintaining ease of operation for healthy users.
3Measurement precision
If comprehensive physiological monitoring is implemented, then detection accuracy of abnormal states is improved, but device complexity and cost increase
Solution Approach 1:
The control device serves multiple functions: it controls the exercise machine operation, queries physiological state data, evaluates safety criteria, and enforces access restrictions. By making the control device multi-functional, the system achieves comprehensive monitoring without adding separate dedicated hardware components, thus maintaining simplicity.

AI summary
A safety ensuring system of exercise machine (16) and a related method includes a physiological detection device (10) and an exercise machine (16). The physiological detection device (10) is used to detect a physiological state of a human body and save the physiological state. Before a user using the exercise machine (16), the physiological state of the user is detected by the physiological detection device (10) first. The exercise machine (16) includes a control device (18) and a working device (20), wherein the control device (18) determines whether the working device (20) is allowed to be used according to the physiological state saved in the physiological detection device (10). The working device (20) is allowed to be used if the physiological state is normal, and it is prohibited from being used otherwise. Whereby, the user in poor physiological state is prevented from doing exercise, which effectively ensures the safety at using the exercise machine (16).
