Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If engine braking is applied when the driver releases the accelerator, then fuel efficiency is improved and primary brake wear is reduced, but the braking force is not adapted to the surrounding environment which may compromise traffic security
Solution Approach 1:
The braking force is dynamically adjusted based on real-time surrounding environment data. The system transitions from static engine braking to dynamic adaptive braking by continuously monitoring environmental factors (obstacles, traffic lights, road gradient, weather) and modifying the braking force accordingly, resolving the contradiction between energy efficiency and traffic security
Solution Approach 2:
The system implements feedback control by acquiring surrounding environment data through sensors, processing this information through a braking force estimation function, and adjusting the braking force based on the estimated optimal value. This closed-loop feedback mechanism ensures both fuel efficiency and traffic security by adapting braking to actual environmental conditions
2Reliability
If braking force is increased to improve traffic security in various environments, then safety is improved, but fuel efficiency deteriorates due to excessive braking
Solution Approach 1:
The system changes the braking force parameter dynamically based on environmental conditions. Instead of applying fixed high braking force for safety, the system adjusts the braking force parameter according to detected environmental factors (reducing braking when safe, increasing when necessary), thereby maintaining traffic security while optimizing fuel efficiency
Solution Approach 2:
The system applies partial braking action only when necessary based on environmental assessment. Rather than continuously applying maximum braking force for safety, the system applies braking force proportionally to the actual safety requirement, avoiding excessive braking that would waste fuel while maintaining adequate traffic security
