Hole Data Input for Eyeglass Lens Rimless Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eyeglass lens processing apparatuses face inefficiencies in inputting hole data for forming holes on eyeglass lenses to attach rimless frames, particularly when multiple holes are required on one lens, as existing methods require manual input for each hole's position, diameter, depth, and angle, making the process cumbersome.
Innovation Solution
A hole data input device that includes a memory for storing target lens shape data and hole patterns, a display for graphic representation, and input means for designating reference positions and intervals, allowing automatic setting of hole positions, diameters, depths, and angles based on selected patterns, reducing the need for manual input of each hole's parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual input method is used for each hole's position, diameter, depth, and angle, then precise hole data can be obtained, but the input process becomes extremely time-consuming and complex when multiple holes are required on one lens
Solution Approach 1:
The system pre-stores multiple hole pattern templates (such as one-hole pattern, two-holes pattern, four-holes pattern) in the memory unit. When a user needs to input hole data, they can directly select from these pre-defined patterns rather than manually inputting each hole's parameters individually. This preliminary preparation of common hole configurations significantly reduces the time required for data input while maintaining precision through the structured pattern definitions.
Solution Approach 2:
The system creates a graphical copy of the lens shape on the display unit and allows users to visually designate hole positions by interacting with this graphical representation. The system then automatically generates the precise hole data (position, diameter, depth, angle) based on the selected pattern and the designated reference position, eliminating the need for manual numerical input of each parameter while maintaining accuracy through the visual-copy method.
2Reliability
If manual input method is used for each hole's parameters, then complete hole data can be obtained, but the operation becomes cumbersome and complex
Solution Approach 1:
The system merges multiple hole parameter inputs (position, diameter, depth, angle) into a single unified operation. By selecting one hole pattern and designating one reference position on the graphical lens display, the system automatically generates complete data for all holes in the pattern. This merging of multiple input tasks into a single selection action maintains data completeness while dramatically improving ease of operation.
Solution Approach 2:
The hole pattern templates serve multiple functions: they define the number of holes, their relative positions, their diameters, their depths, and their angles. A single universal pattern definition can be applied to different lens types and configurations, making the system versatile while simplifying the input process. The same pattern can be reused across different lenses, ensuring consistency and reducing operational complexity.
3Manufacturing precision
If individual hole data input is performed for each hole, then accurate hole parameters can be set, but the device complexity and operational steps increase
Solution Approach 1:
The system segments the hole data input process into two distinct parts: (1) selection of a pre-defined hole pattern that contains the structural relationships between holes, and (2) designation of a reference position on the graphical lens display. This segmentation transforms a complex multi-parameter input task into two simple steps, reducing operational complexity while maintaining precision through the structured pattern definitions that preserve accurate relative positioning and parameter relationships.
