Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellular technology and safety features are integrated into the e-bike, then safety and connectivity are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple safety functions (helmet detection, face recognition, radar, cameras) and cellular connectivity into a single integrated e-bike system controlled by a central processor, reducing the need for separate devices and improving overall safety reliability
Solution Approach 2:
The e-bike's display unit and processor serve multiple functions including cellular communication, helmet status monitoring, face recognition, radar processing, and camera control, allowing one system to perform diverse safety and connectivity tasks
2Reliability
If sensors and cameras are added for surroundings awareness, then safety awareness is improved, but device complexity increases
Solution Approach 1:
The patent divides the safety monitoring system into specialized components: helmet sensors for head protection detection, radar for approaching object detection, and cameras for visual identification, allowing each sensor type to be optimized for its specific function while working together under central control
Solution Approach 2:
The processor acts as an intermediary that receives data from multiple sensors (helmet sensors, radar, cameras) and coordinates their information, processing inputs from various sources to create a unified safety awareness system
3Reliability
If main control unit disables functions based on permission violations, then safety control is improved, but ease of operation decreases
Solution Approach 1:
The system performs preliminary checks by the main control unit to verify user permissions and helmet status before allowing e-bike operation, preventing unsafe operation before it can occur by checking conditions in advance
Solution Approach 2:
The main control unit continuously monitors sensor inputs and provides feedback by disabling functions when permission violations are detected, creating a closed-loop control system that automatically responds to safety conditions
