Numerical Control Light Indicators for Display Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When an anomaly occurs in the display control unit of a numerical control apparatus for machine tools, there is a risk that the machine tool may be unnecessarily stopped, leading to reduced working efficiency as operators cannot determine the correct operating status.
Innovation Solution
Incorporating a first and second light-emitting portion within the numerical control apparatus, which emit light to notify the operator of the machine tool's status and the occurrence of an anomaly in the display control unit, respectively, allowing operators to determine whether to stop the machine tool correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display control unit is used to display machine tool status, then the operator can monitor the system, but when an anomaly occurs in the display control unit, the operator cannot determine the correct operating status and may stop the machine tool unnecessarily
Solution Approach 1:
The patent introduces light-emitting portions as intermediary devices that directly indicate machine tool status and display control unit anomalies. These intermediaries bypass the display control unit, providing reliable status information even when the display system fails, thereby preventing unnecessary stopping and maintaining productivity.
Solution Approach 2:
The patent creates simplified copies of status information through light-emitting indicators that replicate essential machine tool status and anomaly detection capabilities. These light-based copies provide critical information without depending on the complex display control unit, ensuring continuous monitoring reliability.
2Loss of information
If the display control unit is used to display machine tool status, then information can be presented to the operator, but when an anomaly occurs, the operator lacks sufficient information to make correct operational decisions
Solution Approach 1:
The patent segments status information display into two independent parts: light-emitting portions that show machine tool status and operate independently of the display control unit, and the display control unit that shows detailed information when functioning. This segmentation ensures that critical status information remains accessible even when the display control unit fails.
Solution Approach 2:
The patent uses different light emission colors or patterns to indicate different machine tool statuses and anomaly conditions. This visual encoding provides intuitive, easily distinguishable information that helps operators quickly determine correct operational decisions without relying on text-based displays.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents unnecessary stopping of the machine tool during machining by enabling operators to assess the machine tool's status accurately, thus avoiding wasted machining time.
Implementation Method 1
the first light-emitting portion notifies the state of the machine tool or the first control unit by emission of light and the second light-emitting portion notifies by emission of light that an anomaly has occurred in the second control unit

AI summary
A numerical control apparatus for controlling a machine tool, includes: a first control unit for controlling the machine tool for machining; an image display device for displaying at least the status of the machine tool and the first control unit; a second control unit for controlling the image display device; a first light-emitting portion; and a second light-emitting portion, is constructed such that when an anomaly occurs in the second control unit, making the second control unit unable to display the status of the machine tool and the first control unit on the image display device, the first light-emitting portion notifies the status of the machine tool by emission of light and the second light-emitting portion notifies by emission of light that an anomaly has occurred in the second control unit.
