Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scanning methods for detection apparatuses are limited to scanning in one direction, lacking versatility and adaptability to changing scenarios, such as vehicle turns, which can lead to inefficiencies in obstacle detection.
Innovation Solution
A measurement device and method that allows scanning in multiple directions (first and second scan modes) and sending modes, with a control unit determining the appropriate mode based on steering signals, planned routes, and traveling speeds to enhance detection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single scanning direction is used, then the device complexity is reduced, but the adaptability to different driving scenarios deteriorates
Solution Approach 1:
The patent implements dynamic scanning mode selection where the control unit automatically switches between first scan mode (right-to-left) and second scan mode (left-to-right) based on the vehicle's turning direction. This dynamic adaptation allows the system to adjust scanning behavior to match driving scenarios without requiring multiple physical devices, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The patent changes the scanning direction parameter based on steering signals. When the vehicle turns right, the system switches to scanning from right to left; when the vehicle turns left, it scans from left to right. This parameter change approach enables the system to adapt to different driving scenarios while maintaining a single scanning device, thus improving adaptability without proportionally increasing complexity.
2Loss of time
If scanning is performed in the opposite direction of vehicle turn, then obstacle detection time is reduced, but the scanning pattern complexity increases
Solution Approach 1:
The system performs preliminary scanning in the direction opposite to the vehicle turn before the turn is complete. By scanning from right to left when the vehicle turns right (and vice versa), the system proactively detects obstacles in the turning path earlier, reducing detection time. This preliminary action is achieved through simple directional switching rather than complex multi-pattern scanning.
3Productivity
If multiple scan modes are implemented, then detection efficiency during turns is improved, but the control complexity increases
Solution Approach 1:
The control unit receives feedback from the steering signal to determine the vehicle's turning direction and automatically selects the appropriate scan mode. This feedback mechanism enables the system to improve detection efficiency during turns by switching between scan modes based on real-time driving conditions, while the automated feedback-based control keeps control complexity manageable through rule-based decision logic.

Function Achieved in This Case
