Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual sensors are used to detect occupancy, then detection capability is provided, but comprehensive safety monitoring and wireless communication capabilities are lacking
Solution Approach 1:
The patent combines multiple individual sensors (presence sensors, environmental sensors) into an integrated occupancy sensor system that provides comprehensive monitoring capabilities. The system merges sensor data collection, processing, and wireless communication functions into a unified architecture, resolving the contradiction between individual sensor simplicity and system comprehensiveness.
Solution Approach 2:
The occupancy sensor system is designed with multi-functional capabilities including occupancy detection, environmental monitoring, data correlation analysis, and wireless communication. This universal design allows a single system to perform multiple safety-related functions, addressing the limitation of individual sensors while maintaining reliability.
2Quantity of substance
If occupancy data and environmental data are collected separately, then data collection is achieved, but effective correlation and dangerous condition detection are not realized
Solution Approach 1:
The system implements feedback mechanisms where collected occupancy and environmental data are continuously correlated and analyzed. The processor uses the collected data to determine dangerous conditions, and this determination feeds back into activating mitigation systems, creating a closed-loop control system that improves detection accuracy through continuous data correlation.
Solution Approach 2:
The system performs preliminary correlation analysis on collected data to identify patterns indicating dangerous conditions before they become critical. By pre-processing and correlating data in advance, the system can detect potential hazards earlier and more accurately, resolving the contradiction between data quantity and detection precision.
3Ease of operation
If wireless communication capabilities are added to transmit alerts, then remote notification is achieved, but system complexity increases
Solution Approach 1:
The patent introduces a wireless communication bus as an intermediary component that connects the occupancy sensor system to remote electronic devices. This mediator handles the complexity of wireless communication protocols and data transmission, allowing the core sensor system to remain relatively simple while still providing remote alert capabilities.
4Adaptability or versatility
If RFID reader chip is integrated, then vehicle identification and communication capability is improved, but manufacturing complexity increases
Solution Approach 1:
The RFID reader chip is merged with the existing occupancy sensor system architecture, combining vehicle identification functionality with occupancy and environmental monitoring. This integration approach allows the system to gain additional capability while sharing common components and infrastructure, reducing the impact on manufacturing complexity.

AI summary
The present disclosure relates to an occupancy sensor system for a vehicle. The system includes a central processing unit (CPU) electrically connected to a power source of the vehicle, one or more sensors for inputting raw data into the CPU, an electronic device with a user interface, and a wireless communications bus connected to the CPU. The CPU compares the raw data received from the sensors with a predetermined safety threshold and transmits an alert to the electronic device via the wireless communications bus if the raw data is not within the safety threshold. The system further includes a global positioning system (GPS) transceiver coupled to the vehicle for receiving radio transmissions from GPS satellites, and a radio-frequency identification (RFID) reader chip.
