Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for machining workpieces using laser plotters are complex for users, particularly in positioning the workpiece, leading to inaccuracies and increased operational difficulty.
Innovation Solution
A method that enhances user-friendliness by displaying the actual recognized position of identifying features on the computer, allowing for manual correction and automatic adjustment, with visual cues like flashing or color changes to highlight position discrepancies, ensuring accurate positioning without affecting subsequent processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the workpiece positioning and setup on the display element is performed using conventional methods, then the processing can be completed, but the initial positioning is relatively complex for the user
Solution Approach 1:
The system displays the actually recognized position of identification features and graphics on the computer screen, providing real-time feedback to the user. This allows users to see the current positioning status and make necessary adjustments, significantly simplifying the positioning process while maintaining precision.
Solution Approach 2:
The patent creates a visual copy of the workpiece position and identification features on the display element (computer screen). This graphical representation allows users to easily understand and adjust the positioning without directly manipulating the physical workpiece, reducing operational complexity.
2Productivity
If the new position is displayed immediately after processing, then the user can immediately improve recognition for the next process, but this may cause confusion if the position is incorrect
Solution Approach 1:
The patent uses different colors or visual states to indicate the status of position recognition and correction. For example, the new position may be displayed in a different color or with visual cues (such as flashing) to help users immediately recognize position changes and potential errors, allowing for quick verification without confusion.
3Manufacturing precision
If a comparison is carried out between the defined position and actual position during manual correction, then positioning accuracy is improved, but this delays the start of the next processing process
Solution Approach 1:
The system performs comparison only when necessary (during manual correction mode), rather than continuously for every operation. This partial application of the comparison function maintains positioning accuracy when needed while avoiding unnecessary time delays during automated or straightforward processing operations.
