Block Map Conversion for Mixed-Size Mobile Collision Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing block control systems are inadequate for managing a mixed environment of autonomous mobile devices with different sizes, leading to increased production costs and processing loads due to the need for multiple block section maps and complex overlapping relations.
Innovation Solution
The use of individual block section maps with different section sizes and a common reference block section map to represent multiple types of mobile objects, reducing processing load and managing overlapping relations efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple individual block section maps with different section sizes are used to represent different types of mobile objects, then the system can accommodate diverse autonomous mobile devices, but the device complexity and processing load increase due to managing overlapping relations between maps
Solution Approach 1:
The patent introduces a reference block section map as an intermediary layer between individual block section maps. This reference map serves as a common coordinate system that mediates the overlapping relations between multiple individual maps with different section sizes, eliminating the need for complex direct comparisons between individual maps while maintaining accurate collision detection capabilities
Solution Approach 2:
The patent segments the block control system into multiple hierarchical levels: individual block section maps for each mobile object type, a reference block section map as a common framework, and a map converter for transformation. This segmentation allows each component to handle specific tasks independently, reducing overall system complexity while maintaining comprehensive functionality
2Productivity
If a common reference block section map is introduced to simplify map management, then the processing load is reduced, but the device complexity increases due to the additional map conversion process
Solution Approach 1:
The reference block section map serves multiple functions simultaneously: it acts as a common coordinate system for all individual maps, provides a standard framework for collision detection, and enables efficient map conversions. This multi-functionality justifies the added component by consolidating multiple operations into a single universal framework
3Ease of manufacture
If block control is performed with mobile objects of substantially the same size, then the control system is simpler to implement, but the system cannot effectively handle mixed environments with different sized autonomous mobile devices
Solution Approach 1:
The patent applies parameter changes by allowing the block section size parameter to vary according to mobile object type. Each individual block section map uses section sizes appropriate for its specific mobile object type, while the map converter transforms these varying parameters into a common reference framework, enabling both simplicity and adaptability

AI summary
An operation management apparatus includes: a map converter that performs interconversion between a first individual section state corresponding to a first mobile object and a reference section state and interconversion between a second individual section state corresponding to a second mobile object and the reference section state; and a block control controller that determines the first individual section state and the second individual section state to prevent a collision between the first mobile object and the second mobile object based on conversion results of the map converter.
