Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collisions and near collisions frequently occur in outdoor activities due to the difficulty in detecting approaching individuals or vehicles amidst topographical features and natural surroundings, and there is a need for early detection methods to ensure safety, especially for groups of outdoor enthusiasts.
Innovation Solution
A monitoring Bluetooth device equipped with a microprocessor, Bluetooth transceiver, display device, and input device, which includes a group monitoring application to detect and alert users when Bluetooth signal strengths of selected devices fall below a threshold, indicating they are out of range or not detected, using visual, auditory, and vibratory notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual, auditory, and vibratory notifications are implemented to alert users when group members are out of range, then safety monitoring capability is improved, but device complexity increases
Solution Approach 1:
The notification system is segmented into three independent alert mechanisms (visual display, auditory speaker, vibratory motor) that can operate individually or in combination. This allows the system to provide comprehensive safety monitoring through multiple channels while maintaining modular complexity, where each component can be independently controlled and managed by the microprocessor.
2Measurement precision
If Bluetooth signal strength monitoring is continuously performed for multiple devices, then proximity detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The system implements continuous feedback monitoring of Bluetooth signal strength from multiple group member devices. The microprocessor regularly measures signal strength indicators and compares them against threshold values to determine proximity status. This feedback mechanism enables accurate real-time proximity detection while allowing the system to enter low-power states between measurement cycles, balancing precision with energy conservation.

AI summary
A monitoring Bluetooth device for detecting a proximity of a selected group of Bluetooth devices is provided. The monitoring Bluetooth device includes a microprocessor, a Bluetooth transceiver, a memory, and a display device. The memory has a group monitoring application therein. The application determines that first and second Bluetooth signals from first and second Bluetooth devices are being received by the Bluetooth transceiver. The application selects the first and second Bluetooth devices as the selected group of Bluetooth devices in response to first and second user selections. The application displays a first textual message on the display device indicating that at least one Bluetooth device in the selected group of Bluetooth devices has a weak Bluetooth signal in response to the first Bluetooth signal being less than a first threshold signal strength.
