Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation apparatuses provide the same route to all users based on shared traffic and map information, failing to account for individual user needs and experiences during travel.
Innovation Solution
A navigation apparatus that recognizes a vehicle's state and traveling environment using sensors like vibration, weight, speed, and image sensors, and a processor that creates an individualization map by registering and updating drive contexts based on user requests, allowing for personalized route adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the navigation apparatus provides the same route to all users based on shared traffic and map information, then the system complexity is low and operation is simple, but the adaptability to individual user needs deteriorates
Solution Approach 1:
The patent segments the navigation system into two parts: a basic navigation function that provides standard routing to all users, and an individualization map service that segments and personalizes route information based on user-specific drive contexts. This allows the system to maintain simple base operations while adding personalized features through optional segmentation of route data.
Solution Approach 2:
The system performs preliminary actions by pre-collecting and storing drive context information during vehicle operation, then using this pre-collected data to generate personalized route recommendations. The drive context (including vibration patterns, speed profiles, and travel environment data) is captured in advance and processed to create individualized navigation profiles before actual route planning occurs.
2Adaptability or versatility
If the navigation apparatus collects and processes drive context information to create individualization maps, then the adaptability to user needs is improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The patent introduces an intermediary component - the individualization map - that acts as a mediator between raw drive context data and personalized navigation output. This intermediary layer processes and structures the complex sensor data into meaningful user profiles, simplifying the overall system architecture by creating a dedicated buffer and processing layer that handles personalization logic separately from core navigation functions.
Solution Approach 2:
The system creates copies of drive context information and stores multiple versions - including raw sensor data, processed drive context records, and individualization map profiles. These copies are stored in memory and can be referenced independently, allowing the system to analyze and process data without affecting ongoing navigation operations, thereby managing complexity through data replication and parallel processing.
3Measurement precision
If the navigation apparatus uses multiple sensors to detect vehicle state and traveling environment, then the measurement precision of drive context is improved, but the device complexity and cost increase
Solution Approach 1:
The patent applies multi-functionality by using existing vehicle sensors (vibration sensors, speed sensors, steering angle sensors) for multiple purposes - not only for their primary functions but also for collecting drive context information for personalization. This universal approach allows the same sensor infrastructure to serve both vehicle operation monitoring and user profile creation, avoiding additional dedicated sensors and reducing overall system complexity.
Solution Approach 2:
The system merges the collection of drive context data with existing vehicle operation data streams. Instead of creating separate dedicated sensing systems, the patent combines personalization data collection with routine vehicle monitoring, processing vibration, speed, and steering data through a unified system that serves both navigation and user profiling functions simultaneously.
