Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DSRC transceivers are installed along roadways to enable widespread DSRC communication, then communication coverage and system capability are improved, but installation cost and infrastructure disruption increase
Solution Approach 1:
The patent combines the DSRC transceiver with the traffic light assembly into a single integrated unit. The transceiver is mounted on the housing of the traffic light, sharing the same physical structure and power supply. This merging eliminates the need for separate transceiver installations along roadways, reducing installation complexity while maintaining DSRC communication coverage.
Solution Approach 2:
The traffic light assembly is designed to serve multiple functions: traditional traffic signal control and DSRC communication. By making the traffic light structure multi-functional, the system utilizes existing infrastructure for dual purposes, avoiding the need for dedicated transceiver installations and reducing overall system complexity.
2Reliability
If multiple separate receiver units are installed to receive DSRC signals, then signal reception reliability is improved, but system cost and installation complexity increase
Solution Approach 1:
The receiver unit is integrated into the traffic light assembly rather than being installed as a separate component. The traffic light housing serves as the mounting structure for the receiver, and the same power supply energizes both the light emitting elements and the receiver. This consolidation reduces system complexity while maintaining reliable signal reception.
