Segmented Mobile Navigation Route Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile navigation devices face challenges in power consumption and usability, as they consume battery life quickly due to continuous processor usage, display time, and unnecessary visual and audio cues, limiting their use over extended periods.
Innovation Solution
The method involves dividing navigation routes into segments based on complexity, controlling navigation features such as display and audio usage segment-wise, and allowing users to override or reduce features in familiar areas, thereby optimizing power consumption and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If navigation features are continuously activated to provide comprehensive guidance, then navigational usability is improved, but battery life is depleted faster
Solution Approach 1:
The patent divides the navigation route into multiple segments and applies different navigation feature configurations to each segment. Complex segments with many intersections receive full navigation support (display, audio cues), while simple straight segments receive reduced support. This segmentation allows the system to maintain high usability where needed while conserving battery life on straightforward portions of the journey.
Solution Approach 2:
The patent implements partial action by selectively activating navigation features only when necessary. Instead of continuously providing all navigation cues, the system activates display and audio features based on route complexity assessment. This partial activation reduces power consumption while maintaining adequate navigational guidance for complex sections.
2Ease of operation
If visual and audio cues are continuously provided to assist navigation, then user guidance is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by varying the intensity and type of navigation cues based on the local characteristics of each route segment. In complex segments with multiple intersections, the system provides both visual display cues and audio guidance. In simple straight segments, it reduces or eliminates these cues. This localized adaptation ensures adequate guidance where complexity demands it while reducing power consumption in areas where minimal guidance is sufficient.
Solution Approach 2:
The system provides partial action by selectively activating visual and audio cues only when route complexity warrants such guidance. The navigation features are not continuously active but are triggered based on real-time assessment of upcoming route complexity, thereby reducing overall power consumption while maintaining user guidance where necessary.
3Duration of action of moving object
If navigation features are reduced to conserve battery power, then battery runtime is extended, but navigational support quality deteriorates
Solution Approach 1:
The patent segments the navigation journey into complex and simple portions, applying appropriate support levels to each. This ensures that battery runtime is extended during simple segments without compromising navigational support quality during complex segments, where full features remain activated.
Solution Approach 2:
The system applies local quality by maintaining high navigational support quality in complex route segments while reducing support in simple segments. This localized quality adjustment extends overall battery runtime while preserving adequate navigational assistance where route complexity demands it.

AI summary
Apparatuses and methods for managing route navigation via mobile devices. A route is calculated between a starting point and a destination point. The route is divided into multiple segments based on the complexity of the calculated route, and navigation features are controlled as a function of the segment that corresponds to the user's current location. The user may opt to identify one or more segments, or one or more route portions independent of whether or not segmentation has occurred, in order to specify a portion(s) of the route where navigation support is not needed.
