Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver manually observes and reacts to obstructions, then the driver maintains control over the vehicle, but the response time is delayed due to human limitations such as inattention, blind spots, or slow reaction
Solution Approach 1:
The environmental detecting device continuously monitors the driving environment in advance to detect obstructions before they become a threat. The operation module pre-calculates the operating distance based on current speed, and the emergency brake controlling device is ready to activate immediately when an obstruction is detected within the calculated distance, eliminating human reaction delay
Solution Approach 2:
The state detecting device continuously provides feedback on the vehicle's speed and movement state to the operation module. The operation module uses this feedback to dynamically calculate the operating distance and determine whether an obstruction is within the safe stopping distance, creating a closed-loop control system that responds in real-time
2Reliability
If the driver relies on manual observation through the windshield, then the system structure remains simple, but the detection capability is limited by blind spots and environmental factors
Solution Approach 1:
The environmental detecting device with image capturing module serves multiple functions: detecting obstructions, determining their distance, and providing data for operating distance calculation. The operation module integrates multiple detection functions and control decisions into a single system, reducing overall system complexity while improving detection reliability
Solution Approach 2:
The operation module acts as an intermediary between the environmental detecting device and the emergency brake controlling device. It processes image data, calculates operating distance based on speed feedback, and determines whether braking is necessary, simplifying the system architecture while enhancing detection and response capabilities
3Speed
If the automatic emergency brake controlling device is activated, then the response speed to obstructions is improved, but the device complexity increases due to additional sensors and control systems
Solution Approach 1:
The patent combines the environmental detection function, speed feedback function, operating distance calculation, and emergency brake control into an integrated system. The operation module serves as a central hub that coordinates all functions, reducing the need for separate complex control units while achieving fast automatic braking response
Solution Approach 2:
The emergency brake controlling device is designed to work with the existing braking device rather than requiring a completely separate braking system. The operation module performs multiple functions including obstruction detection, distance calculation, and brake control activation, reducing overall system complexity while maintaining fast response speed
