Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple equipment steps are used in the manufacturing process, then the manufacturing precision and quality of optical devices can be maintained, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple manufacturing operations (coating, embossing, and reflector deposition) into a single integrated process sequence that can be performed using fewer equipment pieces. The liquid coating process applies organic layers that are then embossed and have reflector layers deposited in succession, merging steps that traditionally required separate equipment into a streamlined workflow.
Solution Approach 2:
The manufacturing process is designed to perform multiple functions using the same equipment. The coating equipment also handles the deposition of subsequent layers, and the embossing process serves both structural formation and surface preparation for reflector deposition, reducing the need for specialized equipment for each step.
2Reliability
If traditional vacuum coating and wet stripping processes are used, then the release layer can be effectively removed, but the loss of time and increased manufacturing cost occur
Solution Approach 1:
The release layer is designed to be water-soluble from the beginning, allowing for direct aqueous stripping without requiring prior chemical treatment or complex removal procedures. This preliminary design choice enables straightforward water-based removal that eliminates time-consuming intermediate steps.
Solution Approach 2:
The release layer is designed as a disposable, water-soluble component that is easily removed and discarded after serving its purpose. This approach replaces complex, time-consuming removal processes with simple water washing, treating the release layer as a temporary, low-cost element that facilitates the main manufacturing objective.
