Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information display devices for ships and other vehicles fail to promptly display desired information from various sources, such as navigational, radar, underwater detection, image, and weather data, in an efficient and user-friendly manner.
Innovation Solution
A touch-position detection system integrated with processing circuitry that acquires and displays multiple types of information on a divided screen, allowing for dynamic changes in displayed content based on user input, while managing application programs and setting limits on non-essential information to optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple application programs are activated to display various information sources, then the variety and completeness of displayed information is improved, but the device complexity and resource consumption increase
Solution Approach 1:
The system dynamically activates and deactivates application programs based on user interaction. When a user selects a display area, the corresponding application program is activated; when not selected, it is deactivated. This dynamic management allows the system to maintain multiple potential information sources while actually running only the necessary ones, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The information display device provides a universal interface that can display multiple types of information (navigational, radar, weather, etc.) through a single integrated system. The change icon mechanism allows users to access different information sources through a unified interaction method, making the system versatile without requiring separate complex systems for each information type.
2Use of energy by moving object
If application programs are deactivated when not displayed to reduce resource usage, then energy consumption and processing load are reduced, but the speed of displaying desired information decreases
Solution Approach 1:
The system prepares display areas in advance by pre-configuring the interface and keeping application programs in a ready state. When a user interacts with the change icon, the corresponding application program can be rapidly activated because the display framework and data channels are already prepared, minimizing display delay while maintaining energy efficiency through selective activation.
Solution Approach 2:
The system maintains continuous readiness for information display by keeping the display framework and data acquisition channels active. While individual application programs may be deactivated, the underlying infrastructure remains operational, allowing for rapid reactivation and continuous capability to display information without significant interruption.
3Speed
If all application programs are kept running to ensure rapid display of any information, then the speed of information display is improved, but the resource consumption and system load increase
Solution Approach 1:
The system employs dynamic program activation where application programs are started only when needed and deactivated when not in use. This dynamic approach allows the system to maintain fast display capability for currently selected information while conserving resources by not continuously running all possible applications, thus resolving the contradiction between speed and energy consumption.
Solution Approach 2:
The system automatically manages application program lifecycle based on user interaction patterns. When a user selects a display area, the corresponding application is automatically activated; when not selected for a period, it is automatically deactivated. This self-service mechanism optimizes resource usage without requiring manual intervention while maintaining display performance.
4Adaptability or versatility
If the number of selectable information sources is increased to provide more options, then the adaptability and user customization are improved, but the device complexity and operation difficulty increase
Solution Approach 1:
The display screen is segmented into multiple display areas, each associated with a specific application program and information source. This segmentation allows users to navigate and select information sources by interacting with specific display area icons rather than managing a complex list of all available information, simplifying operation while maintaining versatility.
Solution Approach 2:
The change icon serves as an intermediary element between the user and the application programs. Instead of directly managing complex program selections, users interact with the simple change icon in each display area, which mediates the selection process by activating the corresponding application and displaying its information, thus simplifying operation while providing access to multiple information sources.

AI summary
An information display device includes a touch position and processing circuitry. The touch position detector is configured to detect a touched position of a screen. The processing circuitry is configured to acquire a plurality of information, display the plurality of acquired information on a plurality of display areas dividing the screen, respectively, display a change icon on one of the plurality of display areas, and sequentially change the plurality of information assigned as changeable information in the one display area where the change icon is displayed, each time the touched position of the screen is detected at a position where the change icon is displayed.
