Wearable Proximity Warning Assembly for Exercisers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing proximity sensors for exercisers do not effectively alert users to approaching objects from behind, particularly at specific preset distances, leaving them vulnerable to attacks.
Innovation Solution
A wearable proximity warning assembly integrated into a garment, comprising a proximity sensor with an emitter and receiver, and a microcontroller-actuated proximity indicator that generates distinct alerts for different preset distances using time-of-flight calculations or ultrasonic signals, alerting the user when an object is detected within those distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a basic proximity sensor is used to detect approaching objects, then object detection capability is provided, but the ability to alert users at specific preset distances is insufficient
Solution Approach 1:
The detection range is segmented into multiple preset distance zones (first preset distance, second preset distance, etc.). The sensor system divides the continuous space into discrete alert regions, triggering different alerts based on which zone the approaching object occupies. This segmentation enables precise distance-based alerting while maintaining system reliability.
Solution Approach 2:
The system changes the parameter of distance thresholds by implementing multiple preset distance values. Instead of a single detection threshold, the sensor compares object distance against several predefined parameters (e.g., 10 meters, 5 meters, 2 meters), allowing differentiated alert responses based on the specific distance parameter matched.
2Loss of information
If multiple preset distance alerts are implemented, then situational awareness is improved, but device complexity increases
Solution Approach 1:
The proximity sensor system is designed with multi-functionality to handle multiple detection zones and alert types using a single integrated sensor unit. The sensor performs both distance measurement and zone classification functions simultaneously, reducing the need for multiple separate sensors while providing comprehensive distance-based alerting information.
Solution Approach 2:
A microcontroller or processing unit acts as an intermediary between the sensor and the alert output devices. This intermediary component receives raw sensor data, compares it against multiple preset distance parameters, and triggers appropriate alerts based on the matched zone. The intermediary simplifies the overall system architecture by centralizing the decision-making logic.
3Reliability
If a wearable proximity warning assembly is integrated into a garment, then user safety is enhanced, but the device portability and comfort are affected
Solution Approach 1:
The proximity sensor assembly is integrated into flexible wearable components such as bands, straps, or thin garment panels. The sensor housing and mounting structures utilize flexible or thin-film designs that conform to the wearer's body contours, distributing weight evenly and minimizing discomfort while maintaining safety functionality.
Solution Approach 2:
The proximity warning assembly is merged with existing wearable items such as exercise bands, wristbands, or garment seams. By combining the safety function with already-worn accessories, the system adds protective capability without requiring separate additional devices, thereby maintaining ease of operation and wearer comfort.

AI summary
A proximity warning assembly for detecting an approaching object. The proximity warning assembly includes a proximity sensor having an emitter and a receiver. The receiver detects a reflected emission generated by the emitter. The proximity sensor can determine the distance an object reflecting the emission is to the proximity sensor. An alert signal is generated by a proximity indicator that is operably connected to the proximity sensor when an object reaches a plurality of preset distances from the proximity sensor. The device can be worn by a user.
