Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens processing systems suffer from long processing times and inefficient throughput due to fixed assignments between measuring and processing devices, leading to delays and reduced productivity.
Innovation Solution
A modular apparatus with flexible arrangements of measuring devices, processing devices, and conveying devices allows for decoupled measurement and processing, enabling lenses to be fed to any available device, and includes a handling device to manage the sequence and orientation of lenses, with a spindle device for simultaneous processing in rough and fine areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If lenses are processed through a fixed sequence with dedicated handling apparatus and edge processing devices, then measurement and processing can be completed, but the processing time becomes comparatively long and throughput is reduced
Solution Approach 1:
The processing system is divided into multiple independent processing stations (first edge processing device, second edge processing device, third edge processing device) that can operate simultaneously on different lenses. Each station has its own measuring device and processing capabilities, allowing parallel processing of multiple lenses to reduce overall processing time while maintaining quality standards.
Solution Approach 2:
Lenses are pre-measured and positioned on the conveying device before reaching the edge processing devices. The measuring devices at each station perform measurements in advance, and the conveying device is configured to position lenses optimally before processing begins, reducing waiting time and enabling continuous processing without interruption.
2Productivity
If a modular design with flexible arrangement of measuring devices and processing devices is implemented, then throughput and processing speed increase, but device complexity increases
Solution Approach 1:
The conveying device is designed as a universal platform that can transport lenses between different types of processing stations (measuring devices, edge processing devices, polishing devices). Each processing station is configured with similar functional capabilities, allowing the system to handle various lens types and processing requirements through a standardized modular architecture, simplifying operation despite increased throughput capacity.
3Loss of time
If multiple measuring devices and processing devices are linked with flexible arrangement, then the shortest processing time and highest throughput are achieved, but the system requires complex coordination and control
Solution Approach 1:
Each measuring device and processing device is equipped with sensors and control systems that continuously monitor lens position, processing status, and queue conditions. The conveying device receives real-time feedback from all stations and automatically adjusts lens transport timing and routing to optimize flow, balance workloads across stations, and minimize waiting time without requiring complex manual coordination.
