Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If onboard sensors are used to measure parameters such as barometric pressure, then the vehicle can obtain parameter values, but the values may not be optimal during vehicle operation and may interfere with vehicle functions
Solution Approach 1:
The patent extracts the sensing function from the vehicle itself and relocates it to remote stationary sources. Instead of relying on onboard sensors that interfere with vehicle operations, the system obtains parameter values from remote sensors located at fixed geographic positions, thereby eliminating the interference problem while maintaining measurement capability.
Solution Approach 2:
The patent introduces a communication network as an intermediary between the vehicle and the parameter data source. Remote sensors transmit data through the network to the vehicle's processor, allowing the vehicle to obtain accurate parameter values without physical sensors onboard, thus resolving the conflict between measurement needs and operational interference.
2Reliability
If existing sensor techniques are used, then parameter values can be obtained, but redundancy is not provided and costs increase
Solution Approach 1:
The patent makes remote stationary sensors serve multiple vehicles simultaneously. A single remote sensor can provide parameter data to multiple vehicles in its coverage area, creating redundancy across the fleet without requiring each vehicle to have its own sensor, thereby reducing per-vehicle cost while improving reliability through redundancy.
Solution Approach 2:
Instead of each vehicle having its own physical sensor, the system creates data copies from remote sensor sources and distributes them to multiple vehicles via the communication network. This copying approach provides redundancy without the cost of duplicating physical sensors in each vehicle.
3Measurement precision
If onboard sensors are installed, then parameter measurement is enabled, but weight and space on the vehicle increase
Solution Approach 1:
The patent removes the sensing function from the vehicle's weight-bearing structure and relocates it to external remote sources. By extracting the sensor from the vehicle, the system eliminates the weight and space requirements while maintaining the ability to obtain parameter values through remote data transmission.
Solution Approach 2:
The patent replaces the mechanical sensor system (physical sensors mounted on the vehicle) with an electronic/communication-based system. Instead of mechanical sensors adding weight, the system uses software and communication networks to acquire data, substituting physical measurement with digital data transmission.
