External Proximity Indicators for Industrial Machine Detection Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Proximity detection systems in autonomous and semi-automated industrial machines do not provide external feedback to personnel about detected objects, posing safety risks as individuals approaching the machines are unaware of the detection and potential reactions.
Innovation Solution
A proximity detection system configured with sensors and light sources around the industrial machine, controlled by a processor to generate visual feedback indicating the presence and type of detected objects, using different colors, intensities, and patterns of light to alert external personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proximity detection systems are implemented in autonomous industrial machines, then collision avoidance and safe operation are improved, but external personnel are unable to verify detection status and remain unaware of the system's operation
Solution Approach 1:
The patent implements external visual feedback indicators (lights) that provide real-time information about the proximity detection system's operational status and detected objects. These indicators are positioned on the exterior of the machine so that personnel can observe and verify what the sensors are detecting, eliminating the information gap between the detection system and external observers.
Solution Approach 2:
The patent introduces visual indicators as an intermediary between the proximity detection system and external personnel. These indicators translate the internal detection status into externally observable signals, allowing personnel to indirectly observe the detection system's operation without requiring direct access to sensor data or system internals.
2Productivity
If proximity detection systems operate autonomously without external feedback, then operational efficiency is improved, but safety risks increase as personnel cannot verify detection and response status
Solution Approach 1:
The visual feedback indicators maintain autonomous operation while adding a safety layer by allowing personnel to verify that the detection system is active and responding appropriately to detected objects. This feedback mechanism does not interfere with the autonomous decision-making process but provides reassurance and verification for external observers.
Solution Approach 2:
The system provides its own operational status information through external visual indicators, eliminating the need for separate monitoring systems or direct inspection by personnel. The proximity detection system serves itself by communicating its status externally, maintaining efficiency while enhancing safety.

AI summary
Embodiments described herein provide an industrial machine that includes one or more indicators mounted to an external portion of the industrial machine. The one or more indicators are configured to provide an indication to an individual external to the industrial machine that a proximity detection system has detected his or her presence external to the industrial machine. The one or more indicators are controlled to provide the indication to the individual using, for example, different colors of light, different intensities of light, or activation of different indicators.
