Mobile Terminal Navigation Screen Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile navigation devices incur high communication fees and increased power consumption due to GPS usage and image processing, and existing solutions for reducing guidance display are either inconvenient or lack situational adaptability.
Innovation Solution
A mobile terminal device with a direction detection unit, position detection unit, style detection unit, and display control unit that switches between detailed and simple navigation screens based on the device style, reducing unnecessary image processing and communication by displaying direction guidance on a smaller screen when not needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If detailed navigation screen is always displayed, then guidance information is complete and accurate, but power consumption increases and communication fees increase
Solution Approach 1:
The patent applies dynamics by making the display mode adjustable and adaptable rather than fixed. The system dynamically switches between detailed and simple navigation screens based on user preferences, device orientation, and navigation context, optimizing power consumption while maintaining guidance effectiveness.
Solution Approach 2:
The patent applies local quality by providing different levels of information detail in different contexts. Instead of uniformly displaying detailed navigation information in all situations, the system selectively displays simplified directional guidance when appropriate, reducing overall information processing requirements and power consumption while maintaining necessary guidance quality.
2Reliability
If detailed navigation screen is always displayed, then route information is comprehensive, but image processing load increases
Solution Approach 1:
The patent applies the extraction principle by separating essential navigation information (direction and distance) from non-essential detailed route information. The simple navigation screen extracts only the critical directional guidance elements, eliminating the need for complex map image processing while maintaining effective navigation capability.
Solution Approach 2:
The patent applies partial action by providing only the necessary portion of navigation information for each situation. When simple directional guidance suffices, the system displays only that partial information rather than processing and displaying complete route details, reducing computational load while maintaining adequate navigation functionality.
3Use of energy by moving object
If simple navigation screen is displayed, then power consumption is reduced and processing is simplified, but guidance may be insufficient for complicated routes
Solution Approach 1:
The patent applies dynamics by enabling flexible switching between simple and detailed navigation modes based on real-time conditions. The system can transition from simple directional display to detailed route information when complexity increases, ensuring guidance adequacy is maintained dynamically rather than being fixed.
Solution Approach 2:
The patent applies feedback by monitoring navigation context and user interactions to determine when to switch between display modes. The system uses feedback from route complexity assessment and user behavior to adjust the level of information displayed, ensuring adequate guidance is provided when needed while maintaining power efficiency during simpler navigation segments.
4Use of energy by moving object
If automatic shutdown of guidance display is implemented, then power consumption is reduced, but convenience decreases
Solution Approach 1:
The patent applies dynamics by replacing fixed automatic shutdown with adaptive display management. The system dynamically adjusts display duration and mode based on navigation context, device state, and user preferences, maintaining convenience while achieving power savings through intelligent rather than blanket shutdown policies.

AI summary
A control unit obtains a current position of a mobile phone by using a GPS receiver during the operation of the navigation function, while detecting a style of a device body based on detection of an opening/closing sensor. The control unit determines whether to perform route guidance or to perform direction guidance based on the detected style of the mobile phone. When the mobile phone is in “open style”, the control unit displays a detailed navigation screen including route indicating map images on a main display, while displaying a simple direction guidance on a sub display when the mobile phone is in “closed style”.
