Navigation Device Single Detour Input Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation devices require extensive user input to calculate detour routes, which can be cumbersome and unsafe for users encountering dynamic travel conditions such as accidents or road construction, often leading users to forgo additional route calculations.
Innovation Solution
A navigation device with a processor and a single detour input that allows users to request a detour route without extensive input, using a processor to calculate both the primary route and a detour route based on user input, enabling quick and safe navigation around undesirable travel conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing navigation devices require extensive user input to calculate detour routes, then the routing functionality is comprehensive, but the ease of operation deteriorates and users forgo additional route calculations
Solution Approach 1:
The patent extracts and isolates the essential detour request function from the complex route calculation system. By providing a single dedicated detour input button, the system separates the simple user action (pressing one button) from the complex backend processing (calculating alternative routes), thereby improving ease of operation without requiring the user to understand or manage the underlying complexity.
Solution Approach 2:
The system performs self-service by automatically calculating detour routes when the single detour input is activated. The navigation device independently handles route analysis, alternative path calculation, and presentation of detour options without requiring the user to manually identify alternate routes or provide detailed instructions, thus resolving the contradiction between operational simplicity and functional comprehensiveness.
2Reliability
If users are required to manually identify alternate routes and provide detailed information, then the routing accuracy may improve, but the loss of time increases and safety deteriorates
Solution Approach 1:
The system performs preliminary action by pre-calculating and storing multiple alternative routes in advance. When the single detour input is activated, the device can immediately present pre-computed detour options without requiring real-time user input or manual route identification, thereby reducing time loss while maintaining reliable routing through pre-analyzed alternatives.
Solution Approach 2:
The system implements feedback by presenting calculated detour route options to the user for selection. The device analyzes the user's choice and dynamically adjusts the routing calculation, providing feedback loops that improve reliability through iterative refinement while minimizing time loss through efficient algorithms that learn from user preferences and real-time conditions.
3Measurement precision
If extensive user input is required for detour requests, then the routing precision may improve, but the ease of operation worsens and users are less likely to request detours
Solution Approach 1:
The single detour input button serves as an intermediary that bridges the gap between simple user action and complex routing precision. This intermediary element translates a single button press into a sophisticated route calculation process, allowing users to maintain ease of operation while the system handles the precision requirements through automated analysis of geographic data, road conditions, and alternative path evaluation.
Data Source
AI summary
A navigation device with improved detour routing is disclosed. The navigation device is generally operable to calculate a first route to a destination utilizing a current location of the navigation device, receive a detour request from a user provided by the user functioning a single detour input once, and calculate a second detour route to the destination in response to the detour request. Such a configuration enables the user to easily and safely request additional route calculations to provide a detour around undesirable travel conditions without requiring extensive user input.
