Wearable Signal Intensity Based Event Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices manually preset notification methods for events, such as meetings or messages, do not adapt based on the user's distance from the device, leading to inefficient alerting.
Innovation Solution
An electronic device with an event notifying system that establishes a wireless connection with a wearable device, using signal intensity to automatically select between displaying, vibrating, or ringing notifications based on the user's distance, by comparing signal strengths against preset values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual preset notification methods are used, then the device structure remains simple, but the notification effectiveness and user experience deteriorate due to lack of adaptation to user distance
Solution Approach 1:
The system pre-establishes multiple notification methods (display, vibration, ringtone) and preset signal intensity thresholds before actual use. When an event occurs, the system automatically compares the current signal intensity with these pre-set values and selects the appropriate notification method, eliminating the need for manual user configuration and achieving adaptive notification without complex real-time decision logic
Solution Approach 2:
The system autonomously monitors wireless signal intensity, compares it with preset thresholds, and automatically selects the most suitable notification method based on the user's distance. This self-service mechanism eliminates manual intervention, adapts to changing conditions in real-time, and improves notification effectiveness without requiring additional user input or complex external control systems
2Productivity
If automatic distance-based notification selection is implemented, then notification effectiveness improves, but the device complexity increases due to additional sensors and processing
Solution Approach 1:
The system leverages the existing wireless communication module's signal strength detection capability for dual purposes: both for maintaining wireless connection and for determining user distance to select notification methods. By making the wireless module multi-functional, the system achieves automatic distance-based notification selection without adding dedicated distance sensors or separate processing systems, thus improving notification efficiency while minimizing the increase in device complexity
Solution Approach 2:
The system replaces potential mechanical or hardware-based distance measurement approaches with electronic signal intensity analysis. By using the wireless signal strength (an electronic parameter) to infer user distance and select notification methods, the system achieves automated efficient notification without complex mechanical sensors or additional hardware systems, thereby improving productivity with minimal complexity increase

AI summary
A method for notifying an event arising from an electronic device activates a wireless connection between the electronic device and a user-wearable device. A signal intensity of a wireless signal from the wearable device is measured and compared with multiple preset values. The method determines a signal range to which the signal intensity belongs, wherein the multiple preset values define the multiple signal intensity ranges. Notification of an event is issued in the notifying manner corresponding to the intensity range to which the signal intensity belongs.
