Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual control methods are used to synchronize traffic lights at multiple intersections, then the traffic controller can be简单地 connected to traffic lights via grid system, but the synchronization efficiency is low and time-consuming
Solution Approach 1:
The patent replaces the manual mechanical control system with an automated electronic control system. The traffic controller automatically synchronizes traffic lights at multiple intersections using electronic signals transmitted through the grid system, eliminating the need for manual intervention and significantly reducing synchronization time delays.
Solution Approach 2:
The traffic controller is designed to autonomously manage and synchronize traffic lights without requiring constant manual input. The system self-regulates the timing and coordination of multiple traffic lights based on pre-programmed parameters and real-time conditions, improving productivity while minimizing time loss.
2Adaptability or versatility
If manual control is used for modifying traffic lights at multiple intersections, then the existing grid system can be maintained, but the adaptability and real-time modification capability are limited
Solution Approach 1:
The patent replaces manual modification processes with automated electronic control. The traffic controller can remotely and instantly modify traffic light parameters, timing sequences, and operational modes at multiple intersections through the grid system, greatly enhancing adaptability while simplifying the operation of making modifications.
Solution Approach 2:
The traffic controller is designed with multi-functional capabilities to handle various modification needs across different intersections. It can adjust timing parameters, synchronize patterns, and adapt to different traffic conditions universally across the entire network, making the system highly versatile and easy to operate for modifications.
3Productivity
If wireless communication is implemented for remote control, then real-time synchronization and modification efficiency are improved, but the device complexity increases
Solution Approach 1:
The patent replaces physical wired connections with wireless communication technology. The traffic controller communicates with traffic lights and remote systems using wireless signals, enabling real-time synchronization and modification without the complexity of extensive physical wiring infrastructure, thus improving productivity while managing device complexity.
Solution Approach 2:
The patent introduces a remote control system as an intermediary between the traffic controller and the external environment. This intermediary handles complex communication protocols and data processing, allowing the core traffic control system to maintain simplicity while achieving real-time management efficiency through wireless communication.
