Solution Overview
Problem
Existing treadmill safety systems, such as safety keys, are inconvenient for users and do not effectively prevent injuries from falls or foreign objects being drawn under the treadmill.
Innovation Solution
A treadmill equipped with an inertial sensor and a processor that continuously monitors the motion of the treadmill and user, determining an event threshold value based on sensed values, and automatically stopping the treadmill belt if abnormal conditions are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a safety key tied to the user is used, then the treadmill can be stopped when the user falls, but the method is inconvenient for the user
Solution Approach 1:
The system automatically detects accidents using inertial sensors and stops the treadmill belt without requiring user action. The processor analyzes sensed values to determine if an accident occurred, and if so, automatically stops the treadmill, making the safety system self-operating and convenient for users
Solution Approach 2:
The patent replaces the mechanical safety key system with an electronic detection system using inertial sensors and a processor. The inertial sensor detects motion patterns indicating accidents, and the processor controls the motor to stop the treadmill belt, substituting mechanical intervention with electronic sensing and control
2Productivity
If the treadmill operates continuously, then exercise effectiveness is maintained, but injuries may expand when accidents occur
Solution Approach 1:
The inertial sensor continuously monitors the treadmill and user motion, providing real-time feedback to the processor. When the processor detects sensed values indicating an accident, it immediately stops the treadmill belt to prevent injury expansion, creating a closed-loop safety feedback system
Solution Approach 2:
The system continuously senses and analyzes motion data before injuries can expand. By maintaining continuous monitoring readiness and automatically responding to accident conditions, the system takes preliminary protective action before harm can worsen
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively detects accidents in real-time, preventing further injury by stopping the treadmill belt, thus enhancing user safety without the need for user-tied safety keys.
Implementation Method 1
an inertial sensor mounted on the treadmill body continuously senses multiple sensed values
Data Source
AI summary
A treadmill and an exercise accident detection method thereof are provided. The treadmill includes a treadmill body, an inertial sensor, and a processor. The inertial sensor is mounted on the treadmill body and continuously senses multiple sensed values while a treadmill belt of the treadmill is running. The processor is coupled to the inertial sensor, acquires multiple first sensed values sensed within a preset period by the inertial sensor, and analyzes the first sensed values sensed within the preset period to determine an event threshold value. The processor determines whether multiple second sensed values sensed not within the preset period by the inertial sensor satisfy a normal condition according to the event threshold value. If the second sensed values do not satisfy the normal condition, the processor controls the treadmill belt of the treadmill to stop running.
