Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vehicle is parked on a steep slope, then the vehicle can be positioned in a parking space, but the vehicle may roll away or suffer brake failure due to gravity
Solution Approach 1:
The patent introduces a parking assistant system as an intermediary between the driver and the parking process. This system includes sensors that detect slope conditions, a controller that processes the slope information, and an actuator that automatically adjusts the parking brake, thereby mediating the parking operation to ensure safety on steep slopes
Solution Approach 2:
The patent replaces manual mechanical brake operation with an automated electro-mechanical system. The slope sensor detects gravitational effects, the controller processes this information electronically, and the actuator automatically applies or releases the parking brake, substituting the driver's mechanical judgment and action with an automated system
2Ease of operation
If manual brake operation is used on steep slopes, then the driver has direct control, but the driver may not accurately judge the slope and fail to apply the brake properly
Solution Approach 1:
The patent replaces the driver's subjective mechanical judgment of slope with an objective electronic sensing system. The slope sensor precisely measures the inclination angle, and the controller processes this data to determine the appropriate brake application, eliminating the imprecision of human judgment
Solution Approach 2:
The system implements feedback by continuously monitoring slope conditions through sensors and automatically adjusting the parking brake based on the detected slope information. The controller receives real-time data from the slope sensor and adjusts the brake actuator accordingly, creating a closed-loop control system that ensures accurate brake application
3Reliability
If automatic parking systems are implemented, then parking safety is improved, but the system complexity and cost increase
Solution Approach 1:
The patent segments the parking assistance function into three independent modules: a slope sensor module for detecting inclination, a controller module for processing information and making decisions, and an actuator module for executing brake adjustment. This segmentation allows each component to be optimized independently and simplifies the overall system architecture
Solution Approach 2:
The parking assistant system is designed to work with existing vehicle braking systems, making it compatible with various vehicle types and brake configurations. The actuator can interface with different parking brake mechanisms, and the controller can process slope data universally, allowing the system to serve multiple vehicle platforms

AI summary
A parking system includes a cleaning robot and a parking mechanism. The cleaning robot includes a driving mechanism and a rotating wheel. The driving mechanism is drivingly connected to the rotating wheel. The driving mechanism can drive the rotating wheel to rotate. The parking mechanism includes a parking platform, a limiting plate and an elastic element. The limiting plate is rotationally connected to the parking platform through a hinge shaft, and is configured to limit the rotating wheel of the cleaning robot. The elastic element is connected to the limiting plate and configured to maintain a limiting state of the limiting plate. The elastic element defines a spiral space. The limiting plate defines a first hole. The hinge shaft passes through the first hole and the spiral space. The cleaning robot can be docked stably on the parking platform.
