Autonomous Mobile Body Display Control for Restricted-Area Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to distinguish between autonomous moving bodies permitted and not permitted to enter entry-limited regions, leading to confusion among nearby individuals.
Innovation Solution
A management system that includes an autonomous moving body with a display apparatus and a movement managing section to determine and display priority/subordination degrees, allowing nearby people to identify if the moving body is allowed in entry-limited regions based on individual information and geographic unit classifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If autonomous moving bodies use common standard measures for entry-limited regions, then system simplicity is maintained, but nearby people cannot distinguish between permitted and non-permitted moving bodies
Solution Approach 1:
The patent applies color changes by having autonomous moving bodies display different colors based on their permission status for entering restricted regions. Permitted moving bodies display one color (e.g., green) while non-permitted bodies display another color (e.g., red), enabling nearby people to easily distinguish between them without complicating the system architecture
Solution Approach 2:
The patent introduces a display apparatus as an intermediary that communicates the permission status of autonomous moving bodies to nearby people. This display device acts as a mediator between the moving body's internal permission state and external observation, allowing distinction without requiring complex identification systems
2Loss of information
If autonomous moving bodies display priority/subordination degrees, then nearby people can understand movement states, but device complexity increases
Solution Approach 1:
The patent changes display parameters (color, brightness, pattern) based on the priority/subordination degree of autonomous moving bodies. The display control section adjusts these parameters according to permission status and movement state, enabling information communication through simple parameter variations rather than complex display mechanisms
Solution Approach 2:
The display apparatus serves multiple functions: it indicates permission status, shows movement state, and communicates priority level. By making the display device multi-functional, the patent reduces the need for separate indication systems while providing comprehensive information to nearby people

AI summary
A management system (10) that comprises a movement management part (30) that: communicates via communication devices (62, 102) with a plurality of mobile bodies (26) that include autonomous mobile bodies that comprise an autonomous control part (154) that is for autonomous movement; and manages the movement of the plurality of mobile bodies. The autonomous mobile bodies comprise a display device (158) that performs outward-facing display. The movement management part has a superiority determination part (120) that, on the basis of individual information for the plurality of mobile bodies, determines a preference ranking (R) for the movement of the plurality of mobile bodies. The autonomous mobile bodies comprise a display control part (167) that controls the display of the display device in accordance with the preference ranking determined by the superiority determination part.
