Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual tire pressure adjustment is used, then device complexity is reduced, but tire pressure control precision deteriorates leading to premature wear and safety risks
Solution Approach 1:
The system enables automatic self-adjustment of tire pressure through integrated sensors, processors, and valves that autonomously monitor and regulate pressure without manual intervention, resolving the contradiction by making the system self-regulating while maintaining precision
Solution Approach 2:
The system continuously monitors tire pressure via sensors and automatically adjusts pressure through feedback control, comparing actual pressure against target values and making real-time adjustments, thereby achieving precise pressure control through automated feedback mechanisms
2Reliability
If automatic pressure adjustment system is implemented, then tire safety and durability are improved, but device complexity increases
Solution Approach 1:
The system autonomously monitors and adjusts tire pressure without requiring external intervention, improving safety through continuous automatic regulation while managing complexity through integrated design of self-regulating components
Solution Approach 2:
The wheel assembly integrates multiple functions including pressure monitoring, pressure adjustment, and data processing into a single multi-functional system, improving reliability through comprehensive control while managing overall system complexity through functional integration
3Duration of action of stationary object
If continuous pressure monitoring is performed, then tire wear is reduced through optimal pressure maintenance, but energy consumption increases
Solution Approach 1:
The system performs pressure monitoring and adjustment at periodic intervals or based on pressure threshold triggers rather than continuous operation, extending tire service life through regular maintenance while reducing energy consumption by allowing the system to enter low-power states between measurements
Solution Approach 2:
The system automatically adjusts pressure only when needed based on sensor feedback, extending tire life through precise pressure maintenance while minimizing energy consumption by avoiding unnecessary continuous operation of adjustment mechanisms
