Work Machine Operator Safety via Infrared Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lathes pose a safety risk for operators due to rapid workpiece or tool movements, and there is a need for operators to observe work processes while maintaining safety and preventing collisions or machine damage.
Innovation Solution
An electronic visualization device allows operators to observe work processes from a protected area, using cameras and a visualization processor unit to display real-time or simulated work processes, with options for synchronous or time-delayed displays, and infrared imaging to enhance visibility through coolants and lubricants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator directly observes the work area to monitor work processes, then the operator can observe work processes in real-time, but the operator is exposed to safety risks from rapid movements and flying parts
Solution Approach 1:
The patent uses cameras to capture images of the work area and displays them on a screen, creating a visual copy of the work process. This allows the operator to observe work processes remotely without direct exposure to safety risks, resolving the contradiction between safety and observability
Solution Approach 2:
The patent introduces a visualization device with camera and display as an intermediary between the operator and the work area. The camera captures images and the display presents them to the operator, mediating the observation process to eliminate direct exposure while maintaining observability
2Reliability
If the operator remains in a protected area away from the work area, then operator safety is improved, but the operator cannot easily access the work area for setup and maintenance
Solution Approach 1:
The visualization device enables the operator to perform setup and maintenance tasks by viewing the displayed images and manipulating controls remotely. The system provides visual feedback that allows the operator to service the machine without direct physical access to the work area, achieving both safety and ease of repair
3Productivity
If the work processes are displayed synchronously in real-time, then the operator can observe current work processes, but collision analysis and damage prevention capabilities are limited
Solution Approach 1:
The system records images continuously or at relevant events, storing them for later analysis. This preliminary recording action enables subsequent review of work processes, collision analysis, and damage prevention without interfering with real-time synchronous display and operation
