Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional traffic controllers are used, then device simplicity is maintained, but edge processing capabilities are lacking
Solution Approach 1:
The traffic controller is divided into two distinct processing units: an applications processor for executing applications and performing edge processing, and a signal controller processor for controlling traffic lights. This segmentation allows each processor to specialize in its function, enhancing edge processing capabilities while maintaining clear functional separation.
Solution Approach 2:
The applications processor serves multiple functions including executing applications, performing edge processing of sensor data, and communicating with the signal controller processor. This multi-functionality enables the system to handle diverse tasks without requiring separate dedicated hardware for each function.
2Adaptability or versatility
If integrated components are added to expand capabilities, then functionality is enhanced, but device complexity increases
Solution Approach 1:
Multiple functional components are merged into a single integrated traffic controller device, including the applications processor, signal controller processor, memory units, display assembly, and communication interfaces. This integration allows the system to perform multiple functions while maintaining a unified device architecture.
Solution Approach 2:
The retractable display assembly is nested within the controller housing, allowing it to be stored compactly when not in use and extended when needed for user interaction. This nesting approach enables the inclusion of additional functional components without permanently increasing the device's external dimensions.
3Ease of operation
If a retractable display assembly is added, then user interaction is improved, but device complexity increases
Solution Approach 1:
The display assembly is designed to be retractable rather than fixed, allowing it to dynamically change position between retracted and extended states. This dynamic design enables the display to be integrated into the controller housing without permanently increasing its size, while still providing improved user interaction when extended.
4Reliability
If passively cooled components are used, then reliability is increased, but cooling efficiency may be limited
Solution Approach 1:
The processor components are designed with passive cooling capabilities, allowing them to dissipate heat without requiring active cooling mechanisms such as fans or pumps. This self-service cooling approach increases reliability by eliminating moving parts that could fail, while relying on natural convection and conduction to maintain acceptable operating temperatures.
