Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous mobile robots lack effective visual indicators to communicate their status and service conditions to users, leading to difficulties in user interaction and maintenance.
Innovation Solution
An autonomous mobile robot equipped with a light indicator system featuring a light-propagating plate and light sources that generate patterns of illumination along a continuous loop, synchronized with a controller to convey status information, such as operation progress, battery charge, and error locations, ensuring intuitive user understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional status indication methods are used, then the robot can provide basic status information, but the visual feedback is insufficient and difficult to understand for users
Solution Approach 1:
The patent uses different colors of light (red, yellow, green, blue) to represent different status conditions of the robot. The light-propagating plate transmits light from internal sources through its translucent material to create visible color-coded status indicators on the robot's exterior, making status information intuitive and easy to understand at a glance.
Solution Approach 2:
The light-propagating plate is divided into multiple segments or zones that can be independently illuminated to indicate different status conditions. Each segment can be controlled separately to provide specific status information, allowing for detailed and differentiated status communication without overwhelming the user.
2Loss of information
If multiple light sources are used to indicate different status conditions, then comprehensive status information can be provided, but the device complexity increases
Solution Approach 1:
Multiple light sources of different colors are integrated into a single light-propagating plate structure. The plate serves as a unified component that houses and directs light from multiple internal sources, combining what would otherwise be separate indicator systems into one integrated unit, thereby reducing overall system complexity while maintaining comprehensive status indication capability.
Solution Approach 2:
The light-propagating plate serves multiple functions simultaneously: it houses multiple light sources, directs and distributes their light, provides structural support, and acts as the visible interface for status indication. This multi-functionality reduces the need for additional separate components, simplifying the overall system while providing comprehensive status information.
3Loss of information
If a continuous loop light-propagating plate is used, then comprehensive status information can be displayed along the perimeter, but the manufacturing precision requirements increase
Solution Approach 1:
The light-propagating plate incorporates flexible or adaptable features that allow for adjustment during assembly or operation. This dynamic capability compensates for minor variations in manufacturing tolerances, enabling the continuous loop structure to be assembled successfully even with moderate manufacturing precision while still achieving the desired status indication visibility.

Function Achieved in This Case
The light indicator system provides clear and intuitive visual feedback to users about the robot's status and conditions, enhancing user interaction and maintenance by offering consistent visual cues across multiple devices, facilitating easier troubleshooting and operation monitoring.
Implementation Method 1
light sources each being positioned to direct light through a portion of the plate to a portion of the continuous loop
Implementation Method 2
The light sources are configured to direct light through the inner surface of the light pipe toward the outer surface of the light pipe

AI summary
An autonomous mobile robot includes a body, a drive supporting the body above a floor surface, a light-propagating plate positioned on the body and having a periphery defining a continuous loop, light sources each being positioned to direct light through a portion of the plate to a portion of the continuous loop, and a controller to selectively operate the light sources to provide a visual indicator of a status or service condition of the autonomous mobile robot. The drive is configured to maneuver the mobile robot about the floor surface.
