Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a pixel pitch of currently commercialized SLM is used, then device limitation is avoided, but it is difficult to reconstruct a large hologram with high resolution
Solution Approach 1:
The patent divides the holographic display system into multiple functional modules: light source part, spatial light modulator, and display optical system. Each module is simulated independently through separate data interface files, allowing the system to handle large holograms by processing them in segmented portions while maintaining high resolution through coordinated operation of individual modules.
Solution Approach 2:
The patent introduces a standardized data interface layer that operates in a different dimension from the physical SLM constraints. By representing optical characteristics and display structures through abstracted data models (XML schemas), the system can simulate and optimize hologram reconstruction in a computational dimension, enabling large high-resolution holograms without being directly limited by physical pixel pitch.
2Adaptability or versatility
If software library modules are implemented in different structures and programming languages, then flexibility is improved, but compatibility deteriorates
Solution Approach 1:
The patent introduces a standardized data interface as an intermediary layer between different software library modules. This interface, defined through common XML schemas, acts as a mediator that translates between different programming languages and structures, allowing modules written in different languages to interoperably exchange optical characteristic data and display structure information without compatibility issues.
Solution Approach 2:
The standardized data interface serves multiple functions simultaneously: it provides a common communication protocol, defines data formats for various optical characteristics, enables interoperability between different programming languages, and supports both simulation and actual holographic display operations. This universal interface can be implemented across different software architectures and programming environments.
