Modular Lens Processing Layout for Flexible Throughput Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens processing technologies 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 decoupling of 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
1Productivity
If a fixed assignment between measuring devices and processing devices is used, then the system structure is simple, but the processing time increases and productivity decreases
Solution Approach 1:
The system is divided into independent measuring devices and processing devices that are not fixed to each other. Each device can be independently assigned to different lenses based on availability and processing requirements, creating a segmented, flexible architecture that improves throughput while managing complexity through modular design.
Solution Approach 2:
The assignment between measuring devices and processing devices is made dynamic rather than static. The system can adaptively assign lenses to any available device based on real-time conditions, transforming the fixed structure into a dynamic one that optimizes processing flow and reduces waiting times.
2Duration of action of moving object
If lenses are processed sequentially in fixed positions, then the workflow is simple, but the processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-positioning lenses in the receiving device and pre-assigning them to available measuring or processing devices. This allows lenses to be ready for immediate processing without waiting for sequential operations, reducing overall processing time while the control system manages the complexity of coordination.
Solution Approach 2:
The system maintains continuous useful action by ensuring that lenses are constantly being measured or processed without idle waiting periods. The flexible assignment mechanism ensures that as soon as a device becomes available, a lens is immediately assigned and processed, eliminating interruptions and extending the duration of productive work.
3Productivity
If multiple measuring and processing devices are provided, then the throughput increases, but the device complexity increases
Solution Approach 1:
Each measuring device and processing device is designed with universal functionality to handle any lens assignment. The devices can perform the same functions regardless of which specific lens they are processing, allowing flexible redistribution of work across multiple units without requiring specialized assignments, thus managing complexity through standardization.
Solution Approach 2:
A control system acts as an intermediary between the multiple measuring and processing devices, coordinating assignments and managing the complexity of multiple device interactions. This intermediary layer simplifies the overall system management by centralizing the decision-making logic for lens distribution among available devices.
