Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for localizing parked vehicles in large parking areas are inefficient due to the reliance on manual GPS aided RFID scanners, which require additional manpower and time, and inbuilt localization devices often fail to provide accurate or reliable results, especially indoors.
Innovation Solution
A system equipping vehicles with optical senders that emit unique identification signals, which are detected by optical sensors and correlated with vehicle identification information using a data processing device, allowing for precise vehicle localization within the parking area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual GPS aided RFID scanners are used to read RFID chips in parked vehicles, then vehicle location information can be obtained, but additional manpower and time are required and the process must be repeated in defined cycle times
Solution Approach 1:
The vehicle's inbuilt localization device automatically transmits its location information without requiring manual scanning. The device serves itself by continuously providing location data to the server, eliminating the need for periodic manual RFID scanning and updating the parking map automatically.
Solution Approach 2:
The localization device continuously transmits location information rather than requiring periodic manual scanning. This continuous automatic transmission eliminates gaps in location data and removes the need to repeat the scanning process in defined cycle times, maintaining constant awareness of vehicle positions.
2Extent of automation
If inbuilt localization devices are used in parked vehicles, then location information can be obtained automatically, but the devices are not always activated or are not able to provide sufficient accuracy especially indoors
Solution Approach 1:
An optical sender mounted on the vehicle roof acts as an intermediary between the vehicle's inbuilt localization device and the optical sensor in the parking area. This intermediary transmits optical signals that enable accurate location detection indoors, overcoming the limitations of GPS and RFID in indoor environments while maintaining automatic operation.
3Measurement precision
If optical senders are mounted on vehicle roofs, then accurate indoor localization is achieved, but the system complexity increases with additional components
Solution Approach 1:
The optical sender serves multiple functions: it acts as a localization marker for indoor accuracy, provides a visual indicator to help drivers find their vehicles, and can potentially serve as a communication interface. This multi-functionality justifies the additional component by providing multiple benefits from a single addition.
