Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pedestrians use portable devices for mobile applications, then functionality and entertainment are improved, but attention to road safety decreases leading to accidents
Solution Approach 1:
The system continuously monitors the pedestrian's movement state through inertial sensors and provides real-time feedback by emitting warning signals when potential collisions are detected, creating a closed-loop safety mechanism that operates alongside mobile application usage
Solution Approach 2:
The portable device acts as an intermediary between the pedestrian and the environment, using detection systems to sense obstacles and transmitting warning signals to alert the user, thereby mediating the safety issue without interfering with mobile application functionality
2Reliability
If a detection system is added to warn of approaching objects, then safety is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple detection functions (inertial sensing, ultrasonic ranging, infrared detection, camera imaging, and GPS location) into a single integrated portable device that processes all inputs through one control unit, merging previously separate safety systems into a unified device
Solution Approach 2:
The portable device is designed to perform multiple functions simultaneously: mobile applications, safety detection through various sensors, navigation via GPS, and warning signal generation, making a single device universal rather than requiring separate dedicated safety equipment
