Digital Projector Parking Spot Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assisting methods fail to clearly communicate which parking spot a motor vehicle intends to occupy, leading to confusion among pedestrians and other drivers, resulting in traffic jams and inefficiencies, especially in scenarios with multiple parallel parking spots.
Innovation Solution
A parking assisting method utilizing a digital projector to display a projection image indicating the occupied parking spot area, ensuring the image's position remains substantially unchanged relative to the parking spot, even as the vehicle moves, thereby clearly conveying parking information to other traffic participants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If reversing lights or voice prompts are used to indicate parking intent, then other traffic participants can obtain some parking information, but they cannot specifically determine which parking spot will be occupied
Solution Approach 1:
The patent introduces an intermediary device (projection device) that projects visual information onto the ground to indicate the occupied parking spot. This intermediary communicates parking intent directly to pedestrians and other drivers through projected images showing the vehicle's intended parking position, resolving the information gap without requiring complex communication systems between vehicles.
Solution Approach 2:
The patent replaces traditional mechanical/visual signals (reversing lights, voice prompts) with optical projection technology. The projection device creates visual representations of the occupied space on the ground, providing clear spatial information that neither reversing lights nor voice prompts can convey effectively.
2Reliability
If pedestrians or other drivers wait near the parking spot to observe, then they may obtain parking information, but traffic jams occur due to waiting time
Solution Approach 1:
The patent implements preliminary action by projecting the occupied parking spot information before the vehicle actually parks. The projection device displays the intended parking position in advance, allowing pedestrians and other drivers to react immediately without waiting to observe the vehicle's final position, thus eliminating the need for waiting time.
3Adaptability or versatility
If there are several parallel parking spots, then more parking options are available, but pedestrians may mistakenly avoid the wrong parking spot or other vehicles may park in inappropriate locations
Solution Approach 1:
The patent applies local quality by projecting visual information specifically onto the ground area corresponding to the occupied parking spot. The projection device creates localized visual markers that clearly delineate which specific spot is occupied among multiple parallel spots, allowing pedestrians and drivers to precisely identify the correct spot without confusion.
4Ease of operation
If the vehicle moves during parking, then parking maneuver is completed, but the projection image position changes relative to the parking spot
Solution Approach 1:
The patent implements feedback by continuously monitoring the vehicle's position and adjusting the projection image position accordingly. The control system receives feedback about the vehicle's movement and dynamically updates the projection to maintain accurate alignment with the occupied parking spot throughout the parking maneuver.
Solution Approach 2:
The patent applies dynamics by making the projection system adaptive to vehicle movement. The projection device and control system work together to dynamically adjust the projected image position based on the vehicle's real-time position, ensuring the visual information remains accurate despite the vehicle's motion during parking.

AI summary
A parking assisting method, device and system for a motor vehicle are provided. The parking assisting method includes the following steps: obtaining a relative position of an available parking spot relative to the motor vehicle; outputting a display instruction to the digital projector according to the relative position of the available parking spot relative to the motor vehicle; and projecting a projection image to the available parking spot by the digital projector according to the display instruction. The projection image is provided for indicating the available parking spot area will be occupied. The display instruction includes an image position for the projection image, so as to change the position of the projection image in the projection range, so that the position of the projection image in the available parking spot is substantially kept unchanged.
