Exercise Device Proximity Sensor for Foreign Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exercise devices used in confined spaces often face interference or damage from nearby objects, as existing technologies lack effective sensing and response mechanisms to detect and react to objects in proximity, potentially interrupting user activity or causing damage.
Innovation Solution
An exercise device equipped with sensors that detect objects in various spatial zones of proximity, communicating with a console to provide audible and visual warnings or adjust operations, such as slowing or stopping the device, to address the presence of foreign objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If exercise devices are placed in confined spaces with other objects present, then the device can be used in limited areas, but foreign objects may approach too close causing damage or interference
Solution Approach 1:
The system performs preliminary detection of foreign objects in the vicinity of the exercise device before they can cause harm. The sensor continuously monitors the area around the device, and the control system is ready to execute protective actions (warning signals, operation interruption) in advance before actual damage or interference occurs.
Solution Approach 2:
The system establishes a feedback loop where sensors continuously monitor the environment around the exercise device, detect foreign objects, and provide real-time information to the control system. The control system then responds by providing warning signals to users or interrupting operations, creating a closed-loop safety mechanism that adapts to changing conditions.
2Device complexity
If no sensing mechanism is implemented, then the device structure remains simple, but foreign objects can approach without detection causing potential damage or interruption
Solution Approach 1:
The patent replaces complex mechanical sensing mechanisms with electronic sensors and control systems. Instead of using mechanical switches or physical barriers to detect foreign objects, the system employs optical, electromagnetic, or other types of sensors that can detect objects without mechanical contact, thereby maintaining structural simplicity while enhancing safety and detection capabilities.
3Reliability
If the device provides immediate stop response to detected objects, then safety is maximized, but user activity may be unnecessarily interrupted
Solution Approach 1:
The system provides preliminary warning signals to users when foreign objects are detected in the vicinity, giving users advance notice to clear the area or adjust their position. Only when objects approach closer to critical zones does the system interrupt operations, allowing exercise continuity to be maintained as long as possible while still ensuring safety.
Solution Approach 2:
The system implements different response strategies for different spatial zones around the exercise device. Remote detection zones trigger warning signals that allow exercise to continue, while closer detection zones trigger operation interruptions. This localized quality approach ensures safety while minimizing unnecessary interruptions to user activity.

AI summary
An exercise device configured to sense and respond to objects in proximity to the exercise device is provided. The device includes a sensor configured to sense objects in proximity to the exercise device other than the user who is operating the exercise device. A console is in communication with the sensor that instructs components of the treadmill to provide, for example, an audible and/or visual response to the user of the exercise device, or to slow or stop the exercise device from moving. Sensors that are capable of sensing whether objects are within different spatial zones of proximity are disclosed. Multiple pre-defined and/or user-defined responses to objects detected in multiple corresponding spatial zones of proximity are also disclosed herein.
