Parking Spot Projection for Clear Vehicle Occupancy Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assisting methods fail to clearly indicate which parking spot a motor vehicle intends to occupy, leading to confusion among pedestrians and other drivers, which can cause traffic jams and wasted time.
Innovation Solution
A parking assisting method using projection means to project an image onto the parking spot area, adjusting the deflection angle and imaging size to maintain a fixed projection image, allowing pedestrians and other vehicles to accurately identify the occupied spot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If projection means is used to indicate parking spot, then parking information visibility is improved, but projection image shape and size stability deteriorates during vehicle movement
Solution Approach 1:
The patent applies dynamics by making the projection means movable relative to the motor vehicle. The projection means can be deflected to different positions and angles, allowing it to track the vehicle's movement and maintain optimal projection on the parking spot throughout the parking process, thus keeping the projection image shape and size stable despite vehicle motion
Solution Approach 2:
The patent replaces traditional mechanical indication methods (such as physical markers or static signs) with optical projection technology. By using light projection instead of mechanical indicators, the system achieves clearer information transmission and more flexible positioning without physical contact with the parking spot
2Use of energy by moving object
If reversing lights are used to indicate parking intention, then energy consumption is reduced, but information transmission completeness deteriorates
Solution Approach 1:
The patent changes the parameter of information presentation by using projection technology to display visual images of the parking spot on the ground, transforming the indication from simple light signals to comprehensive visual information that clearly shows which specific parking spot will be occupied, thereby improving information completeness while maintaining low energy consumption
