Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglass lens processing apparatuses require complex data input for processing the peripheries and drilling holes for auxiliary lenses, making it difficult for non-experts to accurately attach magnet-type auxiliary lens units to eyeglass frames, often resulting in misalignment and improper fitting.
Innovation Solution
An eyeglass lens processing apparatus with a mode selector for auxiliary lens processing, including a lens chuck shaft, periphery processing tool, drilling unit, and determination unit that automatically sets processing conditions for hole positions based on target lens shapes and distances, simplifying the operation and ensuring precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional eyeglass lens processing apparatuses are used to process auxiliary lenses, then the periphery processing and hole drilling can be performed, but the data input operation becomes complicated and time-consuming
Solution Approach 1:
The determination unit automatically determines processing conditions (hole positions, peripheral shapes) for auxiliary lenses based on target lens shape data, eliminating the need for manual data input. The system serves itself by autonomously calculating and setting all necessary processing parameters without operator intervention.
Solution Approach 2:
The system prestores multiple types of data (lens shape data, hole position data, peripheral processing data) in advance. When processing auxiliary lenses, the determination unit retrieves and applies this pre-stored data automatically, avoiding complex real-time data input operations.
2Manufacturing precision
If manual data input is used for hole positions and target lens shapes, then processing can be performed, but alignment precision deteriorates due to operator error
Solution Approach 1:
The determination unit autonomously calculates hole positions and peripheral shapes by comparing target lens shape data, eliminating manual data setting operations that cause alignment errors. The system self-determines all processing parameters to ensure precise alignment.
Solution Approach 2:
The system uses target lens shape data as a reference to automatically determine auxiliary lens processing conditions, creating a feedback mechanism that ensures hole positions and peripheral shapes align precisely with the target lens specifications.
3Productivity
If multiple pieces of data must be input individually, then processing flexibility is maintained, but operational time increases
Solution Approach 1:
The system merges multiple data input operations into a single automated determination process. The determination unit simultaneously determines hole positions, peripheral shapes, and other processing conditions based on target lens shape data, dramatically reducing operational time.
Solution Approach 2:
By prestoring lens shape data, hole position data, and processing parameters in advance, the system eliminates time-consuming real-time data input operations. All necessary data is prepared beforehand and automatically applied during auxiliary lens processing.
