Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglass lens processing apparatuses lack efficiency in setting the facetting area, particularly for rimless frames, due to cumbersome processing conditions and inefficient visualization tools.
Innovation Solution
An eyeglass lens processing apparatus equipped with a facetting tool, lens chuck, input unit, measuring unit, display unit, and setting unit that allows for precise visualization and setting of the facetting area on both front and side outlines, using tilt angles of the lens surfaces and processing tool surfaces, with options for drilling and grooving tools, and color differentiation for clear visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional processing condition setting methods are used, then the apparatus can process lenses, but the efficiency of setting the facetting area is low and the process is cumbersome
Solution Approach 1:
The patent uses graphical copying of the lens shape to automatically generate facetting area settings. The system creates a visual copy of the lens contour and uses this copy to determine facetting parameters, eliminating the need for manual input of complex processing conditions. This allows operators to set facetting areas efficiently by simply selecting graphical options rather than entering numerous parameters.
Solution Approach 2:
The system performs self-service by automatically calculating facetting area parameters based on the measured lens shape and selected graphical options. The apparatus autonomously determines the facetting boundaries and processing conditions without requiring manual intervention for each parameter, thereby improving setting efficiency while reducing operational complexity.
2Manufacturing precision
If detailed processing parameters are manually set, then processing precision can be maintained, but the time required for setting increases
Solution Approach 1:
The patent implements preliminary action by pre-calculating and storing standard facetting patterns and processing parameters. When a lens is measured, the system automatically applies pre-defined facetting patterns that have been optimized for different lens types, eliminating the need for manual calculation and setting of each parameter while maintaining high precision.
Solution Approach 2:
The system uses feedback from the lens measurement data to automatically adjust facetting area settings. The measurement unit provides real-time feedback on the lens shape and dimensions, and the control unit uses this feedback to precisely determine the facetting boundaries, ensuring manufacturing precision without requiring manual measurement and calculation time.
3Ease of operation
If graphical display of facetting area is implemented, then operator visualization is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by using a single display unit that serves multiple functions: showing the lens contour, displaying the facetting area boundaries, indicating processing parameters, and providing operational feedback. This multi-functional display approach improves ease of operation by consolidating information in one interface while avoiding the need for multiple separate display devices or complex visualization systems.

AI summary
An eyeglass lens processing apparatus for processing an eyeglass lens, includes: a facetting tool that facets an edge corner of the lens which has been finished; a lens chuck that holds the lens; an input unit that inputs a target lens shape; a lens measuring unit that obtains front and rear edge paths of the lens, which has been finished, based on the input target lens shape; a display unit that displays a front outline graphic and a side outline graphic as view from at least one direction based on the measured front and rear edge paths; and a setting unit that sets a facetting area of the lens. The display unit displays the set facetting area in the front and side outline graphics.
