Display Apparatus Highlighting Movable Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In machine tools with multiple movable structures, operators face difficulties in distinguishing which structure a displayed feed axis image corresponds to, leading to potential misrecognition and wrong operations, especially when structures are positioned close to each other.
Innovation Solution
A display apparatus that generates and displays images of movable structures based on their positional relationship, with the ability to highlight the selected structure through distinct color, thickness, or blinking, allowing operators to easily identify the intended structure and axis of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If images of multiple movable structures are displayed near each other on the display device, then the display space is efficiently utilized, but the operator cannot easily distinguish which movable structure the displayed feed axis image corresponds to
Solution Approach 1:
The patent applies local quality by giving each selected movable structure a unique visual characteristic (highlighting) that distinguishes it from others. When a movable structure is selected, its image is displayed with distinctive visual properties such as different color, brightness, or graphical emphasis at its specific location on the display, enabling the operator to easily identify which structure corresponds to the displayed feed axis without requiring excessive display space.
2Device complexity
If the operator relies on indirect recognition of movable structures through feed axis images, then the display layout can be compact, but misrecognition or wrong operation may occur
Solution Approach 1:
The patent implements feedback by continuously updating the display to show the current state of movable structures in response to operator selections and system operations. When the operator selects a movable structure or changes its position, the display immediately reflects these changes through highlighting and positional updates, providing visual confirmation that prevents misrecognition and ensures the operator is controlling the intended structure.
Solution Approach 2:
The patent uses color changes as a visual feedback mechanism to distinguish the selected movable structure from others. The selected structure's image is displayed in a highlighted color or with enhanced visual properties, providing immediate and unambiguous recognition that eliminates reliance on indirect feed axis image interpretation and prevents wrong operations.
3Volume of moving object
If multiple movable structures are positioned close to each other in the machine tool, then the machine tool design is compact, but the operator faces difficulty in distinguishing which structure is the object to be operated
Solution Approach 1:
The patent applies local quality by providing distinct visual characteristics at the specific location of each selected movable structure on the display. Even though the physical structures are positioned close together in the compact machine tool, their images on the display are differentiated through highlighting techniques such as color changes, brightness adjustments, or graphical emphasis, enabling clear structure selection despite physical proximity.

AI summary
A display apparatus has a display on which images of movable structures are displayed, a display image data storage unit storing image data therein, and a display control unit which receives signals relating to the positions of the movable structures from a numerical controller and reads out image data relating to the received movable structures from the image data storage unit, and generates a display image in which images of the movable structures are arranged to have a positional relationship received and displays the display image on the display. When a selection signal for selecting a movable structure to be operated is input to the numerical controller from an input device, the display control unit receives the selection signal and generates a display image in which the image of the movable structure corresponding to the received selection signal is highlighted and displays the display image on the display.
