Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling, fixing, and processing of thin and flexible flat materials, such as anode and cathode foils, in the electronics industry are complex due to their delicate nature and the destructive properties of processing tools like laser beams, requiring a holding device that is both durable and flexible to ensure safe and efficient cutting.
Innovation Solution
A holding device with a worktop and vacuum devices for suction, combined with support modules using brushes, which allows for secure holding and flexibility in movement paths, with modular components for easy replacement and adjustment, ensuring the device can withstand processing tools like saw blades or laser beams without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vacuum devices are arranged at multiple positions on the flat material to ensure secure holding, then the holding reliability is improved, but the device complexity increases and the flexibility of the movement path is limited
Solution Approach 1:
The holding device is segmented into vacuum devices and support modules with brushes. The vacuum devices provide primary holding at critical positions, while the support modules with brushes provide continuous support along the movement path. This segmentation allows the system to achieve reliable holding without requiring vacuum devices at every possible position, thus reducing overall device complexity while maintaining flexibility.
2Reliability
If vacuum devices are arranged at multiple positions on the flat material to ensure secure holding, then the holding reliability is improved, but the flexibility of the movement path is limited
Solution Approach 1:
Support modules with brushes act as intermediaries between the vacuum devices and the flat material. The brushes provide continuous support along the movement path without interfering with the laser beam or other processing tools. This intermediary element maintains holding reliability while allowing the processing tool to move freely along its path without collision with vacuum devices.
3Reliability
If the holding device elements are placed in the movement path of the processing tool to ensure secure holding, then the holding reliability is improved, but the device durability decreases due to contact and destruction
Solution Approach 1:
The support modules with brushes are designed as replaceable, cost-effective components that can withstand contact with processing tools. The brushes are consumable elements that can be easily replaced when worn, allowing the holding device to maintain reliable support along the movement path without compromising the durability of critical vacuum devices. This approach accepts limited lifespan for the brush components while preserving the overall system durability.
