Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the manufacturing device uses a conventional evaporation chamber configuration, then the substrate processing can be completed, but the maintenance time increases and productivity decreases
Solution Approach 1:
The evaporation chamber is divided into multiple independent evaporation sources (first evaporation source, second evaporation source, third evaporation source, fourth evaporation source) that can be maintained separately. This segmentation allows one source to be maintained while others continue operating, reducing overall maintenance time and improving productivity.
Solution Approach 2:
The manufacturing device enables continuous substrate processing by allowing maintenance of individual evaporation sources without stopping the entire system. While one evaporation source undergoes maintenance, other sources continue to deposit organic layers on substrates, maintaining continuous production flow.
2Productivity
If the manufacturing device allows simultaneous operation and maintenance, then productivity improves, but the device complexity increases
Solution Approach 1:
The evaporation chamber is segmented into multiple independent evaporation sources with separate control and maintenance access. This modular segmentation manages complexity by creating manageable, independent units rather than a monolithic system, allowing parallel operation and maintenance.
Solution Approach 2:
The system dynamically switches between operation and maintenance modes for different evaporation sources. The conveyance mechanism dynamically adjusts substrate routing to bypass sources under maintenance, managing operational complexity through adaptive control.
