Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack effective methods to detect and alert users of behaviors that may induce traffic accidents, such as sudden movements, especially in situations where traffic conditions are hazardous.
Innovation Solution
An electronic apparatus, like a smartphone, equipped with an accelerometer and a control program that determines the likelihood of a user's behavior causing a traffic accident by monitoring acceleration data and issuing alerts when predetermined thresholds are exceeded, thereby recognizing sudden movements like running or stopping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acceleration monitoring is implemented to detect hazardous user behaviors, then safety notification capability is improved, but device complexity increases
Solution Approach 1:
The accelerometer already present in the electronic device is repurposed to serve dual functions: its original function and the new safety monitoring function. The device uses its own existing sensors and processing capabilities to detect hazardous behaviors and generate notifications, eliminating the need for additional dedicated hardware components.
Solution Approach 2:
The existing accelerometer component is made multi-functional by applying different analysis methods to the same sensor data. The acceleration data is processed to detect various hazardous behaviors including sudden movements, running, and drowsiness, allowing a single component to serve multiple safety-related detection purposes.
2Measurement precision
If continuous acceleration monitoring is performed to identify sudden movements, then detection capability is improved, but energy consumption increases
Solution Approach 1:
Instead of continuously processing all acceleration data, the system applies threshold-based filtering to identify only those acceleration events that exceed predetermined limits. This partial action approach processes only the necessary portion of data (events above threshold) while ignoring normal variations, reducing computational load and energy consumption while maintaining detection capability for hazardous behaviors.

Data Source
AI summary
An at least one processor determines whether behavior of a user of an electronic apparatus has a high probability of inducing a traffic accident based on an acceleration measured by an accelerometer. The at least one processor issues an alert notification to the user when the at least one processor determines that the behavior of the user has the high probability of inducing the traffic accident.
