Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If drivers use rearview mirrors to observe the environment during parking, then they can see the relative position of the vehicle and parking space, but blind spots remain that cannot be seen
Solution Approach 1:
The patent introduces image capturing modules as intermediary devices that capture environmental images from multiple positions (front, rear, left, right sides of the vehicle). These modules serve as mediators between the driver and the parking environment, providing visual information from blind spots through display devices that show the captured images to the driver.
Solution Approach 2:
The system transitions from two-dimensional mirror reflection to multi-dimensional visual information by placing image capturing modules at multiple positions around the vehicle (front, rear, left, right). This creates a comprehensive three-dimensional view of the parking environment, eliminating blind spots through spatial dimensionality expansion.
2Ease of operation
If drivers manually control the vehicle during parking, then they can adjust the vehicle position, but inexperienced drivers or those in adverse conditions may have difficulty parking safely
Solution Approach 1:
The system implements feedback by using image capturing modules to continuously monitor the vehicle's position relative to the parking space and providing real-time visual feedback to the driver through display devices. The operation module processes this visual information and provides guidance signals to the control device, creating a closed-loop feedback system that improves parking reliability.
Solution Approach 2:
The system enables self-service parking assistance by automatically capturing environmental images, processing the visual information to identify parking spaces, and providing automated guidance signals to control the vehicle. This reduces the burden on the driver and improves parking safety through automated functions.
3Reliability
If the system automatically controls the vehicle to park, then parking safety and convenience are improved, but the device complexity increases
Solution Approach 1:
The system achieves multi-functionality by integrating multiple functions into a unified automated parking system. The image capturing modules serve both manual assistance and automated control functions, the operation module processes information for both modes, and the control device executes both manual and automated commands, reducing overall system complexity through functional integration.
