Vehicle Driver Search Interface for Multi-Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Driver information systems for vehicles often require high levels of attention and skill from operators, leading to potential distractions while driving, especially when searching for information across multiple services, as existing systems lack intuitive and efficient search functionalities.
Innovation Solution
A driver information system with a main search function that simultaneously searches across multiple services and displays links to service-specific search functions, allowing operators to directly access relevant information with reduced distraction and increased ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If service-specific search functions are used to search for relevant information within individual services, then search precision is improved, but operating time increases and distraction potential increases
Solution Approach 1:
The patent combines multiple service-specific search functions into a single main search function that simultaneously searches across navigation, music, radio, and other services. This unified search interface allows operators to access information from multiple services without iteratively switching between individual service search functions, thereby reducing operating time while maintaining search precision through service-specific links.
Solution Approach 2:
The main search function serves as a universal search interface that can search across multiple different services (navigation, music, radio, etc.) simultaneously. This multi-functional search capability eliminates the need for operators to know which specific service to search, reducing the time required to find information while still providing access to service-specific results through displayed links.
2Loss of information
If service-specific search functions are used to ensure relevant search results, then information accuracy is improved, but user complexity increases
Solution Approach 1:
The patent merges the complexity of multiple service-specific search functions into a single main search interface. The system automatically determines which services are available and displays corresponding search results with links to individual service functions. This reduces user complexity by presenting a unified interface while maintaining information accuracy through service-specific search results and direct links to relevant services.
Solution Approach 2:
The main search function automatically identifies and accesses available services without requiring user configuration or knowledge of service structures. The system self-adapts to the vehicle's configured services, automatically determining which search functions to display and how to present results. This reduces user complexity while maintaining accurate access to service-specific information through automatically generated service links.
3Ease of operation
If multiple services are searched simultaneously through a main search function, then operating comfort is improved, but attention requirements increase
Solution Approach 1:
The patent segments the search results from multiple services into distinct, service-specific sections with clear visual separation. Each search result is accompanied by a link to its corresponding service function, allowing operators to quickly identify and access relevant information without being overwhelmed by aggregated results. This segmentation reduces attention requirements while maintaining the comfort of simultaneous multi-service searching.
Solution Approach 2:
The main search function acts as an intermediary that manages and presents results from multiple services in a unified, organized manner. It translates complex multi-service search operations into a simplified interface that displays results with clear service attribution and direct access links. This intermediary function reduces attention requirements by handling the complexity of multi-service coordination while providing operating comfort through a single search entry point.
