Innovation Solution

A parking system with a limiting plate and elastic element, such as a torsion spring, connected via a hinge shaft, which limits the rotating wheel to ensure stable docking on a parking platform, incorporating a parking mechanism with cross and longitudinal beams for comprehensive positional stability.

Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improveparking capabilityVSAvoidvehicle stability
Core Design Contradiction:
Ease of operationVSReliability

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

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical 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

Engineering Contradiction:
Improvedriver controlVSAvoidslope judgment accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

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

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Inventive Principle:
Principle #23Feedback

3Reliability

If automatic parking systems are implemented, then parking safety is improved, but the system complexity and cost increase

Engineering Contradiction:
Improveparking safetyVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #6Universality (Multi-functionality)
