Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple slots are provided to support various image interface formats (HDMI, DisplayPort, MHL), then the device can process different image signal formats, but the circuit board complexity and layout costs increase
Solution Approach 1:
The patent implements a single slot that can accept connectors from multiple image interface formats (HDMI, DisplayPort, MHL) by defining a universal pin assignment scheme where pins are assigned functions based on detection results. The image processing device detects which connector type is inserted and automatically configures the pin functions accordingly, allowing one physical slot to serve multiple interface formats without requiring separate dedicated slots for each format.
2Adaptability or versatility
If multiple slots are provided to support various image interface formats, then the device can process different image signal formats, but the number of pins and chip size increase
Solution Approach 1:
The patent defines a pin assignment scheme where a single set of pins serves multiple interface formats. By detecting the connector type and dynamically configuring pin functions, the same physical pins can be assigned to different signal functions depending on which interface format is detected, thereby reducing the total number of pins required compared to having separate dedicated slots for each format.
Solution Approach 2:
The patent employs dynamic parameter changes by detecting the connector type and automatically adjusting the electrical characteristics and signal assignments of the pins. The image processing device changes the operational parameters of the pins based on the detected interface format, allowing the same hardware resources to be efficiently utilized across different standards without requiring additional pins for each format.
3Adaptability or versatility
If multiple slots are provided, then various image interface formats can be supported, but user operation becomes inconvenient due to the need for correct connector placement and signal source selection
Solution Approach 1:
The patent implements automatic detection and configuration functionality where the image processing device autonomously identifies the inserted connector type and configures the appropriate signal processing parameters without user intervention. The system performs self-service by detecting which interface format is connected and automatically selecting the correct processing method, eliminating the need for users to manually configure settings or worry about correct connector placement.

AI summary
An image processing device for processing an image signal is provided. The image processing device includes a circuit board, a slot and an image processing module. The slot, disposed on the circuit board, is to be plugged in by either a first connector corresponding to a first image interface format or a second connector corresponding to a second image interface format. The image processing module, disposed on the circuit board and coupled to the slot, detects the image signal inputted from either the first connector or the second connector to determine a target image interface format, and processes the image signal by an image processing method corresponding to the target image interface format.
