Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual payment processes are used for time difference determination, then payment can be made, but the process requires increased effort and complexity
Solution Approach 1:
The system performs automatic time difference determination and payment processing without manual intervention. The RFID device in the vehicle automatically exchanges signals with detection devices to record entry and exit times, and the communication device automatically completes payment transactions based on the calculated time difference, eliminating the need for manual payment processes
Solution Approach 2:
The patent replaces manual mechanical payment processes with automated electronic systems. RFID technology substitutes for manual time recording, and electronic communication devices substitute for manual payment transactions, thereby reducing effort and complexity in the payment process
2Productivity
If automated methods are implemented for time difference determination, then speed and reliability are improved, but device complexity increases
Solution Approach 1:
The automated system is divided into distinct functional modules: RFID devices in vehicles for identification, detection devices for signal exchange and time recording, evaluation devices for calculating time differences, and communication devices for payment processing. This segmentation enables automated high-speed operation while managing complexity through modular design
Solution Approach 2:
The detection devices serve multiple functions: they detect RFID signals from vehicles, record entry and exit times, and communicate with evaluation devices. The evaluation devices both calculate time differences and control barrier devices. This multi-functionality reduces the number of separate components needed, managing system complexity while maintaining automated productivity
3Extent of automation
If RFID devices are integrated into vehicle tires, then automatic identification is achieved, but manufacturing complexity increases
Solution Approach 1:
The RFID device is integrated into the tire structure, merging the identification function with the existing tire component. This allows automatic vehicle identification when the tire rotates and passes near detection devices, achieving high automation without requiring separate identification systems
Solution Approach 2:
The RFID device integrated in the tire is a relatively simple, cost-effective component that can be manufactured and replaced easily if needed. This approach keeps manufacturing complexity manageable while achieving automatic identification functionality
