Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers often struggle to locate their vehicles in unfamiliar parking lots, leading to confusion and inefficiency when returning after parking.
Innovation Solution
An electronic device that communicates with surrounding vehicles using V2V technology, generating and broadcasting data packages containing vehicle information, allowing drivers to navigate back to their parked vehicles without relying on GPS, by utilizing a network of nearby vehicles to determine the vehicle's location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS is used to locate vehicles in parking lots, then global positioning capability is provided, but positioning accuracy deteriorates due to signal blockage and multipath effects in enclosed parking structures
Solution Approach 1:
The patent introduces surrounding vehicles as intermediary objects to mediate the location determination process. Instead of relying directly on GPS satellites, the system uses nearby vehicles equipped with transmitters and receivers to establish communication paths and determine relative positions, thereby overcoming GPS signal blockage in enclosed parking structures
Solution Approach 2:
The patent combines multiple data sources including transmitter identifiers from surrounding vehicles, receiver signal strength measurements, and map data into a unified location determination system. This integration of multiple information sources compensates for the unreliability of GPS alone and improves overall positioning accuracy in challenging environments
2Measurement precision
If a network of surrounding vehicles is used to locate the target vehicle, then location accuracy in parking lots is improved, but system complexity increases due to multiple communication nodes and data processing requirements
Solution Approach 1:
The patent segments the location determination task into multiple independent components: transmitter vehicles broadcast their identifiers, receiver vehicles measure signal characteristics, and a separate processing system integrates the data with map information. This segmentation allows each component to operate independently and simplifies the overall system architecture despite the complexity of the V2V network
Solution Approach 2:
The system enables surrounding vehicles to automatically participate in the location determination process without requiring manual configuration or intervention. Vehicles autonomously transmit their identifiers, receivers automatically measure signal strengths, and the system self-organizes the communication network, reducing operational complexity despite the increased number of nodes
3Loss of time
If drivers manually remember parking locations, then no additional technology is required, but time is lost and confusion occurs when returning to unfamiliar parking lots
Solution Approach 1:
The patent performs preliminary actions by having the vehicle's electronic device automatically record parking location information and establish communication with surrounding vehicles at the moment of parking. This advance preparation eliminates the need for drivers to manually remember locations and enables rapid vehicle retrieval when returning to the parking lot
Solution Approach 2:
The system provides feedback to drivers through the electronic device, which receives location data from surrounding vehicles and communicates the target vehicle's position back to the driver. This feedback loop replaces manual memory with an automated information return system, reducing both time loss and driver confusion
Data Source
AI summary
A method for locating a vehicle left parked in a parking lot can be applied by an electronic device in the hands of the driver. The method generates a first data package based on the vehicle and the same is broadcast to other vehicles in the parking lot as a parking space is being found. A second data package is generated when the driver takes his electronic device away from the parked vehicle and sent to the other vehicles within a preset range. Upon the driver's return, the parked vehicle can generate a navigation path to itself. The navigation path sent by the parked vehicle is received by the electronic device, and the electronic device can prompt a driver to locate his/her own parked vehicle according to information of the navigation path.
