Movable Object Display Device for External Status Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices for movable objects, such as vehicles, do not effectively convey the status and future intentions of the object to people outside, particularly in terms of deceleration and turning, which can impact safety.
Innovation Solution
A display device with a controller that adjusts the display mode and brightness based on the object's status, including deceleration and turning intentions, using multiple display units and lamps to provide clear and dynamic visual information to external observers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display unit shows multiple types of information simultaneously, then information completeness is improved, but information clarity and visibility are worsened
Solution Approach 1:
The display unit is divided into a first area for displaying status information and a second area for displaying other information. The controller selectively controls the second area to display or hide information based on the current status, thereby segmenting the display space to avoid information confusion while maintaining completeness.
Solution Approach 2:
The display mode is dynamically adjusted based on the status variation. When status information needs emphasis, the controller configures the display unit to prioritize status information visibility, thereby dynamically optimizing information clarity based on current needs.
2Illumination intensity
If display brightness is increased to improve visibility, then visibility is improved, but energy consumption is worsened
Solution Approach 1:
The brightness of the display unit is adjusted as a variable parameter based on the current display needs and environmental conditions. The controller can dynamically change brightness levels to ensure visibility while minimizing energy consumption, rather than maintaining constant high brightness.

AI summary
A mobile-body display device (1) comprises: a display (2) that is disposed so as to be visible from outside of a mobile body (100); and a control unit (4) that causes the display (2) to display information indicating the state of the mobile body (100). The control unit (4) causes the display mode of the information displayed by the display (2) to change in accordance with changes in the state of the mobile body (100).
