Ship Radar Display Segmentation for Navigation Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ship radar systems require frequent manual adjustment of scale size to balance detailed views of nearby and distant areas, leading to difficulties in navigating and referencing routes and landmarks effectively.
Innovation Solution
An information display device that acquires positional information on display targets, including landmarks and movable bodies, and uses a controller to display this information in an information display area, associating targets outside the area with their direction relative to the movable body, allowing for simultaneous display of detailed information close to and far from the movable body's location, with customizable display conditions to reduce clutter and enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the scale size is enlarged to display detailed information of nearby area, then the detail visibility is improved, but the route and distant landmarks cannot be referred
Solution Approach 1:
The display screen is divided into two distinct regions: an information display area showing detailed radar images of the nearby area, and an outer circumferential area displaying simplified positional information of distant landmarks and route. This segmentation allows both detailed and distant information to be displayed simultaneously without interference.
Solution Approach 2:
The patent transitions from a single-scale display to a multi-scale display by adding a second display layer (outer circumferential area) that shows distant information. This dimensional addition to the display structure enables simultaneous presentation of both near and far information at appropriate scales.
2Loss of information
If the scale size is reduced to display distant area, then the route and distant landmarks can be referred, but the detailed position and shape of echo cannot be grasped
Solution Approach 1:
The display is segmented into two functional zones: the inner information display area maintains enlarged scale for detailed echo analysis, while the outer circumferential area uses reduced scale to show route and distant landmarks. This resolves the contradiction by providing appropriate scale in each spatial zone.
Solution Approach 2:
Different display qualities and scales are applied to different regions of the screen. The center region provides high-detail radar imagery for local area analysis, while the peripheral region provides contextual navigation information at a broader scale, allowing each region to optimize its display quality for its specific purpose.
3Loss of information
If multiple types of information are displayed simultaneously, then comprehensive navigation information is provided, but the display becomes cluttered and visibility degrades
Solution Approach 1:
Information is segmented by spatial location and type: detailed radar echoes occupy the central information display area, while simplified symbolic representations of landmarks and route are placed in the outer circumferential area. This spatial segmentation prevents information clutter while maintaining comprehensiveness.
Solution Approach 2:
The patent displays only the most essential information in each region rather than all possible data. The outer circumferential area shows simplified positional information of landmarks and route without detailed characteristics, providing sufficient navigation context without overwhelming the display.

AI summary
This disclosure provides an information display device. The information display device includes an acquirer for acquiring positional information on one or more display targets including at least one of a landmark serving as a reference mark used when a movable body is in move, another movable body, and a location registered by an operator, and a controller for displaying positional information and circumferential information on the movable body in an information display area, associating at least one of the one or more display targets of which a position is outside the information display area with a direction to which the at least one of the one or more display targets is located centering on the movable body, and displaying the at least one of the one or more display targets in an outer circumferential area of the information display area.
