Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the parking system performs an initial parking operation into a first parking space along a first path, then the parking operation can be completed, but the system cannot detect or select a better parking space that becomes available during the operation
Solution Approach 1:
The parking system dynamically adjusts the parking path during the parking operation. The processor continuously detects parking spaces and can switch from the first path to a second path when a better parking space is detected and user input is received. This dynamic adaptability allows the system to respond to changing environmental conditions while maintaining operational efficiency.
Solution Approach 2:
The system implements feedback by continuously detecting parking spaces during the parking operation and providing this information to the user through the display unit. The user can provide input based on this feedback to switch to a better parking space. This feedback loop enables the system to adapt to new information without completely aborting the parking operation.
2Ease of operation
If the system allows switching between parking paths during operation, then user convenience is improved, but the system complexity increases
Solution Approach 1:
The processor performs multiple functions: it executes the initial parking operation, continuously detects parking spaces, generates multiple parking paths, and handles user input for path switching. This multi-functionality is achieved within a single control unit, avoiding the need for separate dedicated systems for each function and thus limiting the increase in overall system complexity.
Solution Approach 2:
The system generates the second parking path in advance during the initial parking operation, before the user needs to make a decision. This preliminary preparation of alternative paths allows for quick switching when user input is received, improving ease of operation without requiring complex real-time path generation during the switch.
3Adaptability or versatility
If the system detects a second parking space during initial parking operation, then better parking spaces can be selected, but the parking operation time increases
Solution Approach 1:
The system performs partial detection and path generation during the initial parking operation. Instead of completely re-planning the entire parking operation when a second parking space is detected, the system only generates the alternative second path and waits for user input. This partial action approach maintains productivity by avoiding complete re-planning while still providing adaptability.
Solution Approach 2:
When user input is received to switch to the second parking space, the system rushes through the path switching process by using the pre-generated second path. This allows quick transition to the better parking space without extensive recalculation, thereby minimizing the impact on parking operation efficiency.

AI summary
An autonomous parking system includes an object detection apparatus, and one or more processors. The one or more processors are configured to: perform an initial parking operation for parking a vehicle into a first parking space along a first path, the first path including one or more first turnaround points; during the initial parking operation, detect a second parking space using the object detection apparatus; generate a second path for parking the vehicle into the second parking space; and, in response to user input, perform at least one of a first parking operation along the first path or a second parking operation along the second path.
