Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple fixed image signal receiving interfaces are provided, then the number of supported image formats is limited, but the device complexity increases
Solution Approach 1:
The patent implements a universal image processing architecture where a single image processing module can handle multiple image formats (HDMI, VGA, 3G-SDI, RGB, YCbCr) through a unified signal processing path. The expansion module provides universal compatibility by accepting various input formats and converting them to a standard internal format, eliminating the need for separate processing circuits for each format type.
Solution Approach 2:
The patent introduces an expansion module as an intermediary component between the image input units and the image processing module. This expansion module acts as a mediator that receives multiple format signals, performs format conversion and signal normalization, and outputs standardized signals to the processing module, thereby simplifying the overall system architecture while maintaining multi-format support.
2Quantity of substance
If the number of image signal receiving interfaces is increased, then more image signals can be received, but the device structure becomes more complex
Solution Approach 1:
The patent divides the image receiving system into modular components: multiple image input units (each with specific interface capabilities), an expansion module for signal management, and a unified image processing module. This segmentation allows the system to receive multiple image signals simultaneously while maintaining a clean, organized structure where each module has a specific function, reducing overall system complexity.
Solution Approach 2:
The patent merges multiple image signal processing functions into a single integrated image processing module. Instead of having separate processing circuits for each input interface, the system combines all format conversion, signal conditioning, and image processing operations into one unified module, thereby reducing device structural complexity while maintaining the ability to process multiple simultaneous signals.
3Ease of manufacture
If fixed receiving formats are used, then the interface design is simple, but the flexibility to adapt to different formats is reduced
Solution Approach 1:
The patent implements a dynamic format adaptation mechanism where the expansion module can automatically detect the input signal format and dynamically adjust its processing parameters. The system includes format detection circuits that identify the incoming signal type (HDMI, VGA, 3G-SDI, etc.) and dynamically configure the signal processing path accordingly, allowing the interface to adapt to different formats without requiring manual configuration or complex switching mechanisms.
