Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors (distance sensors and image sensors) are installed to provide comprehensive maneuvering guidance, then the reliability of obstacle detection is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent applies multi-functionality by enabling a single image sensor to perform multiple functions: detecting obstacles, identifying traffic signs, determining vehicle motion trajectory, and providing guidance information. This replaces the need for separate distance sensors and image sensors, reducing system complexity while maintaining comprehensive detection capabilities
Solution Approach 2:
The patent merges the functions of multiple sensors into a single image-based system. By combining obstacle detection, traffic sign recognition, and motion tracking into one integrated image processing system, the patent reduces the number of components and simplifies installation while achieving reliable comprehensive guidance
2Measurement precision
If multiple sensors are used to detect obstacles and provide guidance, then the measurement precision of distances is improved, but the cost of the system increases
Solution Approach 1:
The patent uses image copying and processing techniques to extract distance information from visual data. By analyzing the position and size of objects in captured images, the system determines distances without requiring expensive dedicated distance measurement sensors, achieving accurate measurement at lower cost
Solution Approach 2:
The patent replaces mechanical/electronic distance sensors with an optical-based image processing system. By substituting physical sensing devices with computational image analysis, the system achieves comparable or superior measurement precision while significantly reducing hardware costs
3Reliability
If a comprehensive maneuvering system is implemented to cover blind spots, then the driving safety is improved, but the ease of operation and installation is worsened
Solution Approach 1:
The patent makes the image sensor universal by programming it to perform multiple safety functions: detecting obstacles in blind spots, identifying traffic signs, tracking vehicle motion, and providing guidance. This single multi-functional device covers all safety needs without requiring multiple specialized sensors, greatly simplifying installation
