Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Parking vehicles in home garages is challenging due to tight spaces, making it difficult for drivers to maneuver and park accurately.
Innovation Solution
A system utilizing a vehicle controller, display, and garage camera to provide boundary lines superimposed on the camera feed, assisting the driver in parking by determining pixel changes and notifying when the vehicle is properly aligned within the garage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a driver manually maneuvers a vehicle into a home garage, then the driver has full control over the vehicle, but the tight space makes it difficult to park accurately
Solution Approach 1:
The patent introduces a garage camera system as an intermediary between the driver and the tight garage space. The camera captures video feed showing boundary lines and vehicle position, serving as a mediator that provides visual information to help the driver park accurately without directly controlling the vehicle's physical movement.
Solution Approach 2:
The system implements feedback by continuously monitoring the vehicle's position relative to garage boundary lines through camera video feed and pixel change detection. This feedback loop provides real-time information about parking progress, allowing the driver to make precise adjustments to achieve accurate parking in the tight space.
2Ease of operation
If the garage space is made larger to accommodate easy maneuvering, then the driver can move the vehicle more easily, but the home garage typically cannot be enlarged
Solution Approach 1:
The patent creates a visual copy of the garage environment through camera imaging. The video feed displays boundary lines and vehicle position, effectively copying the physical garage space into a visual representation that the driver can use for navigation, compensating for the limited physical space.
Solution Approach 2:
The system transitions from three-dimensional physical maneuvering constraints to two-dimensional visual information display. By projecting boundary lines and vehicle position onto a video feed, the system adds a visual dimension that helps the driver navigate the tight physical space more effectively.
3Measurement precision
If visual guidance systems are added to assist parking, then parking accuracy improves, but the system complexity increases
Solution Approach 1:
The garage camera system serves multiple functions: it captures video feed for visual guidance, detects pixel changes to determine vehicle position, and provides feedback for parking accuracy. This multi-functionality reduces the need for separate specialized components, thereby limiting the increase in system complexity while maintaining high parking accuracy.
Solution Approach 2:
The system uses the existing garage camera and its video feed to provide self-service for parking guidance. The same camera that monitors the garage space is utilized for detecting vehicle position through pixel change analysis, eliminating the need for additional dedicated sensors or complex detection systems.

AI summary
A method includes determining that the vehicle is approaching a garage and receiving a video from a garage camera and determining a frame difference per pixel with respect to time as the vehicle moves into the garage and counting a number of rows of pixels with no changes as the vehicle moves into the garage using the frame difference per pixel. Further, the method includes comparing the number of rows of pixels with no changes as the vehicle moves into the garage with a predetermined row threshold to determine whether the number of rows of pixels with no changes with respect to time as the vehicle moves into the garage is less than or equal to the predetermined row threshold and commanding a display to provide a notification indicative that the vehicle is properly parked in the garage.
