Parking Guidance Signals for Obstacle and Line Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems fail to provide clear signals to drivers regarding the availability of space around the vehicle, particularly when obstacles or parking lines are close, increasing the risk of collisions during parking.
Innovation Solution
A parking assistance system comprising a processor, proximity sensor module, and indicator that uses sensors to detect distances from obstacles and lines, and provides visual and auditory signals to guide the driver on whether to continue or stop vehicle motion based on threshold distances, using green and red lights or sounds to indicate safe parking paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing parking assistance systems detect obstacles and lines, then the system can identify potential hazards, but the system fails to provide clear directional guidance signals to drivers
Solution Approach 1:
The patent applies color-coded visual signals (green for safe/continue, yellow for caution/slow down, red for danger/stop) to provide intuitive directional guidance to drivers. This color-change system transforms complex sensor data into simple, universally understood visual cues that clearly indicate whether the driver should continue moving, slow down, or stop the vehicle.
Solution Approach 2:
The system implements real-time feedback by continuously monitoring distance to obstacles and lines, processing this information through the processor, and immediately providing corresponding visual signals to the driver. This closed-loop feedback mechanism ensures the driver receives up-to-date guidance based on the current parking situation, enabling responsive and safe maneuvering.
2Reliability
If the system provides continuous monitoring of distance, then collision risk is reduced, but the system complexity increases
Solution Approach 1:
The patent replaces complex mechanical monitoring systems with electronic sensors (ultrasonic, infrared, or optical sensors) that automatically detect obstacles and lines. This substitution reduces mechanical complexity while enhancing reliability, as electronic sensors provide continuous, precise distance measurement without moving parts, enabling robust collision prevention through software-based threshold comparison and signal generation.

AI summary
A parking assistance system for helping a driver park a vehicle includes a processor, a proximity sensor module, and an indicator. The proximity sensor module is operably coupled to the processor and is configured to detect a distance of the vehicle from a line on a driving surface or an obstacle. An indicator is operably coupled to the processor. The processor is programmed to cause the indicator to present a continue motion signal when the distance of the vehicle from the line or the obstacle is greater than a threshold distance and to cause the indicator to present a stop motion signal when the distance of the vehicle from the line or the obstacle is equal to or less than the threshold distance.
