Solution Overview
Problem
Users taking selfies may accidentally capture dangerous environments behind them, leading to accidents due to unawareness of their surroundings.
Innovation Solution
A mobile electronic apparatus equipped with an image acquisition device and a multi-axis sensing device that captures images and detects orientation information to determine if the user is in a potentially dangerous environment, suspending the shooting mode when necessary to prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image acquisition device continuously operates in shooting mode to capture selfies, then the user convenience and functionality are improved, but the risk of accidents in dangerous environments increases
Solution Approach 1:
The system performs preliminary detection of the background environment before allowing the shooting mode to operate. By analyzing images captured by the image acquisition device and comparing them against dangerous environment databases, the system proactively identifies potential hazards and prevents shooting mode activation in dangerous areas, thus eliminating accident risks before they can occur.
Solution Approach 2:
The system continuously monitors the environment during shooting mode operation and provides real-time feedback to the user. When dangerous environments are detected through image analysis and orientation data, the system immediately notifies the user and suspends shooting functionality, creating a closed-loop safety mechanism that dynamically adjusts operation based on environmental conditions.
2Reliability
If the system adds multi-axis sensing device and environmental detection capabilities to prevent dangerous selfies, then the safety is improved, but the device complexity increases
Solution Approach 1:
The image acquisition device serves multiple functions: it captures selfies for normal operation and simultaneously captures background images for safety detection. The same hardware components are reused for both photography and environmental monitoring, eliminating the need for separate dedicated safety detection devices and reducing overall system complexity.
Solution Approach 2:
The system merges the safety detection functionality with the existing imaging system. The image processing unit that normally processes selfie images is also used to analyze background environments for hazards. By combining these functions into a unified processing pipeline, the system achieves enhanced safety without proportionally increasing hardware complexity.
