Vehicle Notification System Using Beacon Signals and Auxiliary Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle notification systems, such as those using GPS data, are insufficient in accuracy, making it difficult for users to find a target vehicle, especially in valet parking scenarios where multiple individuals share the same vehicle and parking positions may change or be unclear.
Innovation Solution
A notification system that provides both position information and auxiliary information, such as voice, photographs, or text, to help users locate the vehicle, along with a beacon-based system that outputs a signal when entering a predetermined area, allowing users to easily identify the vehicle's location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS data is used for vehicle location notification, then the system can provide position information, but the accuracy is insufficient for users to easily find the target vehicle
Solution Approach 1:
The notification system segments the location information into multiple types: primary position information (GPS coordinates) and auxiliary information (photographs, voice descriptions, text details). This segmentation allows the system to provide both broad location context and specific visual/audible cues for precise vehicle identification, resolving the contradiction between limited GPS accuracy and ease of vehicle finding.
Solution Approach 2:
The notification unit acts as an intermediary that translates imprecise GPS data into multiple forms of auxiliary information (photographs showing vehicle appearance, voice descriptions, text details). These intermediary representations bridge the gap between coarse GPS positioning and precise vehicle identification, enabling users to easily locate their vehicles even when GPS accuracy is limited.
2Ease of operation
If only position information is provided, then the notification system is simple, but users cannot easily identify the target vehicle among multiple vehicles
Solution Approach 1:
The system segments notification information into hierarchical levels: essential position information for basic location guidance, and optional auxiliary information (photographs, voice, text) for enhanced identification. This segmentation enables the system to remain simple when only position information is needed, while providing comprehensive auxiliary details when users need to distinguish their vehicle from others, thus balancing ease of operation with manageable complexity.
Solution Approach 2:
The notification unit provides partial information (position data) by default to maintain system simplicity, but can supply excessive information (multiple types of auxiliary details) when needed for vehicle identification. This partial-or-excessive approach allows the system to adapt its complexity level based on user needs, providing just enough information to solve the specific problem without always deploying the full complexity of the system.
3Ease of operation
If multiple types of auxiliary information are provided, then users can easily find the vehicle, but the information transmission requires more resources
Solution Approach 1:
The notification system applies local quality by providing different types of auxiliary information tailored to specific contextual needs: photographs for visual identification, voice descriptions for auditory confirmation, and text details for precise information. Rather than uniformly providing all information types, the system selectively delivers appropriate auxiliary information based on local conditions and user requirements, optimizing information quantity while maintaining ease of vehicle finding.
