Machine Tool Workspace Lighting for Workpiece Holding Status Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current workpiece monitoring systems in machine tools require operators to leave the workspace to check the pick-up status, leading to increased workpiece changing times, reduced ergonomics, and potential inaccuracies in machining due to the need for external feedback.
Innovation Solution
A device that utilizes an existing lighting system in the machine tool's workspace to provide visual feedback on the workpiece's pick-up status through a signal operating mode, eliminating the need for external controls and allowing operators to correct positioning without leaving the work area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If feedback on workpiece pick-up status is provided on a control panel outside the workspace, then the monitoring function is achieved, but the operator must leave the workspace to check status, increasing workpiece changing time and reducing ergonomics
Solution Approach 1:
The patent moves the feedback interface from the external control panel dimension to the internal workspace dimension by using the workspace lighting system. Instead of requiring the operator to move to an external location to check status, the status information is projected into the workspace itself through selective illumination patterns, allowing the operator to remain in position and immediately see feedback about workpiece pick-up status.
Solution Approach 2:
The patent makes the workspace lighting system serve dual functions: its primary function of illuminating the workspace for operations, and a secondary function of displaying status information through selective activation of light sources. This eliminates the need for separate external signaling devices and allows the same physical infrastructure to provide both operational lighting and feedback communication.
2Reliability
If feedback on workpiece pick-up status is provided on a control panel outside the workspace, then the monitoring function is achieved, but operator ergonomics are reduced due to required movement outside the work area
Solution Approach 1:
The patent relocates the feedback interface from the external control panel dimension to the internal workspace dimension. By projecting status information into the workspace through the lighting system, the operator can receive feedback without leaving the comfortable work area, significantly improving ergonomics while maintaining reliable monitoring.
Solution Approach 2:
The workspace lighting system serves itself by providing dual functionality. The same light sources that illuminate the workspace also convey status information, eliminating the need for separate external signaling systems and allowing the operator to receive feedback within the workspace without physical movement.
3Reliability
If external signaling devices are used to provide feedback on workpiece status, then monitoring is achieved, but device complexity increases due to additional structural components
Solution Approach 1:
The patent eliminates additional structural components by making the existing workspace lighting system perform dual functions. The same light sources and control infrastructure used for workspace illumination are also used to display status information, thereby reducing device complexity while maintaining reliable feedback functionality.
Solution Approach 2:
The patent merges the lighting function and status display function into a single integrated system. By combining these two previously separate functions into the workspace lighting system, the patent reduces the number of separate components and simplifies the overall system structure while achieving both illumination and feedback communication.
