Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional brake light systems are used, then the system is simple and reliable, but the brake status information provided is insufficient for various driving conditions
Solution Approach 1:
The brake lighting system is divided into multiple independently controllable light regions (first brake light region, second brake light region, third brake light region) that can be activated selectively based on braking intensity. This segmentation allows the system to provide differentiated brake status information without requiring a completely new complex system architecture.
Solution Approach 2:
The lighting system transitions from static brake light activation to dynamic control where different regions are activated based on real-time braking intensity detection. The system adaptively adjusts which light regions are illuminated according to the detected braking force, providing context-appropriate brake status information.
2Loss of information
If multiple light regions are activated to provide additional brake status information, then information completeness improves, but energy consumption increases
Solution Approach 1:
Different regions of the brake lighting system are activated selectively based on the local condition of braking intensity. Instead of uniformly activating all light regions, the system applies local quality control where only the necessary regions are illuminated according to the specific braking situation, optimizing energy usage.
Solution Approach 2:
The system changes the activation parameter of different light regions based on the detected braking intensity parameter. As braking intensity varies, the system dynamically adjusts which regions are active, creating a parameter-driven energy optimization strategy that balances information provision with energy conservation.
3Reliability
If brake lights flash under hard braking to warn following vehicles, then warning effectiveness improves, but the system lacks adaptability to different driving conditions
Solution Approach 1:
The brake lighting system dynamically adapts its behavior based on real-time detection of braking intensity and driving conditions. The system transitions from fixed flash patterns to dynamic control where the activation of different light regions responds to varying driving scenarios, enhancing both reliability and adaptability.
Solution Approach 2:
The system incorporates feedback from braking intensity detection to control which light regions are activated. This closed-loop control ensures that the lighting response is appropriately matched to the actual braking condition, providing reliable warnings while adapting to different driving situations.
