Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If passive RFID technology is used for railcar identification, then the system is simple and low-cost, but location tracking is limited to when the railcar passes an AEI reader and real-time monitoring is not possible
Solution Approach 1:
The patent combines AEI reader functionality and GPS tracking capabilities into a single integrated wireless device mounted on the railcar. This merging allows the device to communicate with both trackside AEI readers for identification and wireless network nodes for continuous location tracking, resolving the contradiction between tracking precision and system complexity.
Solution Approach 2:
The wireless device performs multiple functions: it acts as an AEI tag for railcar identification, a GPS receiver for location determination, and a wireless communicator for data transmission. This multi-functionality enables continuous tracking while avoiding the need for separate dedicated devices, thus improving measurement precision without proportionally increasing complexity.
2Adaptability or versatility
If separate AEI tags and GPS devices are used, then comprehensive tracking functionality is achieved, but hardware complexity and management difficulty increase
Solution Approach 1:
The patent integrates the functionalities of AEI tags and GPS devices into a single wireless device. This consolidation maintains comprehensive tracking functionality while reducing hardware complexity and management burden, as operators now manage only one device instead of separate AEI tags and GPS units.
Solution Approach 2:
The wireless device is designed with universal capabilities to perform AEI identification, GPS location tracking, and wireless communication simultaneously. This multi-functional design achieves comprehensive tracking functionality while avoiding the hardware complexity that would result from using separate specialized devices.
3Productivity
If continuous location tracking is implemented, then real-time monitoring capability is improved, but energy consumption increases
Solution Approach 1:
The wireless device employs periodic action by transmitting location information to wireless network nodes at scheduled intervals rather than continuously. This periodic transmission maintains real-time monitoring capability while significantly reducing energy consumption compared to continuous data transmission, as the device can enter low-power states between transmission cycles.
